Technical & Integrations
2FA (two-factor authentication) is a security method that requires, in addition to the password, a second confirmation, usually a code sent to a phone or generated by an app.
Turning on 2FA in a CRM sharply reduces the risk of unauthorised access to client data.
CRM Fundamentals
A 360° client record is the complete view of a client on one screen, bringing together contact details, communication history, quotations sent, orders, invoices and attached files.
Any team member can then take over the client relationship without searching for information in separate sources.
Sales & Leads
An account in a CRM is the record that represents a client company, grouping several contact persons and opportunities under it.
The account structure is essential in B2B sales, where an organisation as a client involves several contacts.
CRM Fundamentals
An activity in a CRM is any recorded action related to a client or opportunity: a call, an email, a meeting or a note.
The activity log builds the full history of the relationship and keeps continuity across the team.
Artificial Intelligence
An AI analysis in a CRM uses artificial intelligence to examine data and offer recommendations: it identifies promising leads, prioritises opportunities and highlights trends.
The team can then make decisions it would miss when analysing large volumes of data by hand.
Technical & Integrations
An API (Application Programming Interface) is a set of rules that lets two software applications communicate and exchange data automatically.
In a CRM, APIs enable integration with invoicing platforms, online stores, calendars and social networks.
Technical & Integrations
An audit trail is the chronological record of all changes and actions made in the system, with author and date.
In a CRM, the audit trail provides full traceability and helps with compliance and with investigating errors.
Technical & Integrations
An authentication token is a secure digital code that confirms the identity of an application or user when accessing an API, instead of sending the password repeatedly.
In CRM integrations, tokens enable secure connections with external platforms such as invoicing or e-commerce.
Sales & Leads
An automated review system collects client feedback through follow-up messages and SMS triggered by order status.
A CRM analyses the feedback in real time and turns it into concrete improvement actions.
Technical & Integrations
Automation in a CRM means running repetitive tasks automatically, such as sending follow-up emails, generating quotations and invoices, capturing leads from forms or importing online orders.
Automation frees the team from manual work and reduces human error.
Sales & Leads
The difference between B2B and B2C is that B2B (business-to-business) sales are made to other companies, with long cycles and several decision-makers, while B2C (business-to-consumer) sales are made to individuals, with faster decisions.
CRMs are configured differently for B2B and B2C workflows.
Technical & Integrations
A backup is a safety copy of data, made regularly so information can be recovered after a technical failure or loss.
In a self-hosted CRM, backups are configured automatically inside the company’s own network, for maximum safety.
Technical & Integrations
Batch processing means handling a large group of tasks or records at once, at a scheduled time, instead of one by one.
In CRM/ERP, batch processing is used for overnight synchronisations, invoicing runs or bulk imports.
Technical & Integrations
A bulk import loads a large volume of records into a CRM at once, usually from a CSV or Excel file.
Bulk import speeds up the initial setup, bringing thousands of contacts into the system in minutes.
Artificial Intelligence
Business Intelligence (BI) is the set of technologies and processes that turn a company’s raw data into reports and analyses useful for strategic decisions.
KPI reports and AI analyses in a CRM are applied forms of business intelligence.
Technical & Integrations
A calculated field is a field whose value is generated automatically from other fields, for example the total value of a quotation from price and quantity.
Calculated fields reduce errors and save time in a CRM.
Finance & Invoicing
Cash flow is the movement of money into and out of a company over a given period.
The payments module of a CRM keeps track of cash flow and payment history, for informed financial decisions.
ERP & Architecture
A product catalogue is a company’s standardised list of products or services, with codes, names and prices.
The catalogue in a CRM/ERP fills in automatically on quotations, invoices and documents, reducing errors.
Finance & Invoicing
Churn (customer attrition rate) is the percentage of clients who stop working with a company over a given period.
Tracking churn in a CRM helps identify clients at risk of leaving early and take retention action.
Finance & Invoicing
Client retention is a company’s ability to keep its existing clients over the long term, the opposite of churn.
A CRM supports retention through reminders to get back in touch, automatic follow-up and the full history of each relationship.
Technical & Integrations
A cloud CRM (SaaS – Software as a Service) is a system hosted on the vendor’s servers, accessed over the internet and paid as a recurring monthly subscription.
The advantage is quick setup; the drawbacks are recurring costs and the fact that data is stored externally, not on the company’s own hosting.
Sales & Leads
Cold, warm and hot lead describe a prospect’s level of interest: cold (new contact, low interest), warm (moderate interest) and hot (ready to buy).
A CRM classifies leads by these levels to prioritise the sales approach.
Sales & Leads
A commission is the amount paid to an agent as a percentage of the sales they generate.
A CRM calculates commissions automatically from closed deals, removing manual calculation errors.
Sales & Leads
A contact person is the individual associated with a client or account, with whom the team communicates directly.
A CRM links several contact persons to the same account, keeping each one’s role and history.
Sales & Leads
Conversion is the moment a lead becomes a client, completing the desired action (a purchase, signing a contract or placing an order).
The conversion rate measures the percentage of leads who become clients and is one of the most important sales performance indicators.
CRM Fundamentals
A CRM (Customer Relationship Management) is software that brings together in one place all information about clients, leads, quotations and communication, in order to manage client relationships and organise the sales process.
A CRM removes data scattered across spreadsheets and emails, giving every team member the full history of each client.
ERP & Architecture
The difference between CRM and ERP is that a CRM manages clients and sales (leads, quotations, pipeline), while an ERP manages internal resources (accounting, stock, production, payroll).
The two systems complement each other and can be integrated for a complete data flow between sales and operations.
Technical & Integrations
A cron job (scheduled task) is an automatic action that runs at set time intervals, with no human intervention.
CRMs use cron jobs for recurring automations such as sending reminders or synchronising data.
Sales & Leads
Cross-selling is the technique of offering products or services that complement what the client already buys.
The CRM suggests relevant cross-selling by analysing the client’s previous orders and preferences.
Technical & Integrations
CSV (Comma-Separated Values) is a simple file format in which data is organised in rows and columns separated by commas.
CSV files are the most common way to import or export client databases from a CRM.
Technical & Integrations
A custom field is a field added by the user in a CRM to store information specific to their business, beyond the standard fields.
Custom fields adapt the CRM to each company’s unique workflow, without complex development.
Technical & Integrations
A custom status is a user-defined stage a lead or opportunity goes through in the pipeline, adapted to the real sales process.
Being able to create your own statuses makes the CRM pipeline reflect exactly how the team works.
Sales & Leads
The customer journey is the whole path a client follows, from becoming aware of a brand to buying and staying loyal.
A CRM maps the customer journey so you can step in with the right message at each stage.
CRM Fundamentals
A dashboard is a CRM’s main control screen, showing the most relevant indicators in real time: active leads, quotations sent, revenue generated and tasks in progress.
The dashboard gives an instant picture of the business’s health, without separate reports.
Technical & Integrations
Data encryption turns information into code that cannot be read without a decryption key, protecting it in case of unauthorised access.
A secure CRM encrypts sensitive data both at rest and in transit over the internet.
Technical & Integrations
A data export extracts information from the CRM into an external file (CSV, Excel, PDF) for reporting, backup or transfer.
Being able to export guarantees that you control your data and can move it at any time.
Technical & Integrations
A data import transfers existing information (from Excel, CSV or another CRM) into the new system when you start using it.
A good CRM allows a secure import of the client base without loss, usually within a few hours.
Technical & Integrations
Data migration is the process of moving information from an old system to a new one, preserving the integrity and structure of the data.
When adopting a CRM, correctly migrating the client base from Excel or a previous system is essential for continuity.
Technical & Integrations
Data protection rules — the EU General Data Protection Regulation (GDPR) and, in the UAE, Federal Decree-Law No. 45 of 2021 (PDPL) — set strict requirements for collecting, storing and processing clients’ personal data.
A self-hosted CRM makes compliance easier, because data stays stored on the company’s own server, with no transfers to external clouds.
Sales & Leads
A deal is a concrete sales opportunity with an estimated value, tracked from start to close in the pipeline.
In a CRM, every deal has a status, a value and a win probability that feed the forecasts.
Technical & Integrations
A dedicated server is a physical or virtual machine used exclusively by one company, without sharing resources with other users.
Hosting a CRM on a dedicated server ensures consistent performance and complete data isolation.
Technical & Integrations
Deduplication is the process of finding and removing duplicate records from a database, for example the same client entered twice.
Deduplication features in a CRM keep the database clean and avoid confusion in client communication.
Sales & Leads
A drip campaign is a series of automated messages sent at set intervals to a lead or client, guiding them step by step towards a decision.
In a CRM, drip campaigns keep contact going without manual effort, increasing the chances of conversion.
Technical & Integrations
A dynamic form is built by drag and drop, and its fields can adapt based on the user’s answers.
In a CRM, dynamic forms capture leads from the website and send them straight into the pipeline, with no code.
Technical & Integrations
An electronically signed contract is a digitally signed document with legal validity, removing the need to print and sign on paper.
Modern CRMs generate contracts with two-party electronic signature, completing the agreement between company and client in a few steps.
Sales & Leads
Email marketing means sending commercial or informational messages to a list of contacts, in order to generate sales or maintain client relationships.
CRMs integrate with email marketing platforms and synchronise the client base automatically for targeted campaigns.
Technical & Integrations
An endpoint is a specific URL of an API through which a given resource or function is accessed, for example the client list or creating an invoice.
Every CRM integration uses distinct endpoints to read and write data between systems.
ERP & Architecture
An ERP (Enterprise Resource Planning) is software that integrates and centralises a company’s internal processes — accounting, stock, procurement, production, human resources and logistics.
Unlike a CRM, which looks towards clients and sales, an ERP looks towards the company’s internal operations.
Technical & Integrations
Failover is the automatic switch to a backup system when the main component fails, to maintain continuity.
In a critical CRM infrastructure, failover reduces downtime when something breaks.
Sales & Leads
A follow-up is the action of getting back to a client or lead after a first contact, by email, phone or SMS, to continue the conversation and move closer to the sale.
CRMs automate follow-up, sending personalised messages based on each contact’s status and history.
Sales & Leads
Forecasting is estimating future revenue based on the opportunities in the pipeline and their probability of closing.
A CRM automates the forecast, giving managers a realistic projection of results.
Technical & Integrations
An embedded widget (often via an iframe) is a CRM component displayed directly on another website, for example a booking or contact form.
Widgets let you capture leads directly from the company’s website, with no redirect.
Technical & Integrations
An incremental backup saves only the data changed since the last backup, reducing the space and time needed compared with a full backup.
A CRM backup strategy combines periodic full copies with frequent incremental backups.
Technical & Integrations
An integration is the connection between the CRM and another application (invoicing, e-commerce, email, calendar) that lets data synchronise automatically between the two systems.
Integrations remove manual data entry and keep information up to date in real time.
CRM Fundamentals
An internal note is a comment added to a client record, visible only to the team, to keep useful context and observations.
Internal notes in a CRM make sure important information is not lost between colleagues.
Technical & Integrations
JSON (JavaScript Object Notation) is an easy-to-read text format used to exchange data between applications.
Most CRM APIs send and receive data in JSON format, thanks to its simplicity and universal compatibility.
Sales & Leads
Kanban is a visual way of organising work in which tasks or opportunities appear as cards in columns representing stages, and the cards move from one column to the next as they progress.
In a CRM, the Kanban view of leads and quotations gives immediate visual control over the sales flow.
CRM Fundamentals
A Kanban board is the visual interface in which leads or quotations appear as cards in columns representing stages, movable by drag and drop.
The Kanban board in a CRM gives an immediate picture of each opportunity’s status.
Finance & Invoicing
A KPI (Key Performance Indicator) measures how well a team or company is meeting its objectives, for example conversion rate, average order value or revenue per agent.
A good CRM provides automatic KPI reports for data-based decisions.
Sales & Leads
A landing page is a web page dedicated to a single campaign or offer, designed to convert visitors into leads.
Landing pages connect to the CRM to capture the details of interested visitors automatically.
Technical & Integrations
Latency is the delay between sending a request and receiving the response in a computer system.
Low latency makes a CRM respond quickly, which is essential for team productivity.
Sales & Leads
A lead is a potential client who has shown interest in a product or service, for example by filling in a form, asking for a quotation or leaving contact details.
In a CRM, leads are captured automatically from web forms, campaigns or imports and tracked step by step until they become clients.
Sales & Leads
Nurturing is the process of developing the relationship with leads who are not yet ready to buy, through relevant content and communication over time.
CRMs automate nurturing through email sequences triggered by the lead’s behaviour.
Sales & Leads
Lead qualification is the process of assessing how well a prospect fits the ideal profile and whether they have a real chance of buying.
A CRM supports qualification with clear criteria and scoring, directing the team’s effort towards valuable leads.
Sales & Leads
Lead routing is the automatic process of assigning new leads to the right agents, based on rules such as territory, product or availability.
A CRM with lead routing makes sure every lead quickly reaches the right person.
Artificial Intelligence
Lead scoring is the method of giving each lead a score based on how likely they are to become a client, using behaviour and demographic data.
CRM systems with artificial intelligence calculate this score automatically, helping the team prioritise high-potential leads.
Finance & Invoicing
A lifetime (perpetual) licence is a software purchase model in which you pay once and own the right of use permanently, with no recurring monthly subscription.
It is the opposite of the SaaS model and, for a CRM, turns the cost into an investment that is fully paid off.
Artificial Intelligence
Machine learning is the branch of artificial intelligence through which a system learns from data and improves its predictions without being explicitly programmed for each case.
In a CRM, machine learning underpins lead scoring and sales forecasts.
ERP & Architecture
Master data is a company’s essential, stable reference data — clients, products, suppliers — used consistently across all modules.
Synchronising master data between CRM and ERP avoids inconsistencies and double entry.
Technical & Integrations
Middleware is an intermediate software layer that enables communication and data exchange between two applications that could not otherwise connect directly.
In complex integrations, middleware translates and routes data between the CRM and external systems.
CRM Fundamentals
A module is a distinct functional component of a CRM, dedicated to an area such as sales, invoicing, stock or support.
A modular architecture lets each business activate only the functions it needs.
Sales & Leads
An MQL (Marketing Qualified Lead) is a lead who has shown interest through marketing actions (downloaded a resource, subscribed) and is considered ready for closer contact.
In a CRM, MQLs are flagged to be handed over to the sales team at the right moment.
Technical & Integrations
Multi-tenant architecture means several clients share the same software instance (typical of SaaS), while single-tenant means an instance dedicated exclusively to one company.
A self-hosted CRM is single-tenant by definition, offering isolation and full control of data.
Technical & Integrations
OAuth is a standard authorisation protocol that lets an application access data in another service without knowing the user’s password, using access tokens.
CRMs use OAuth to connect securely to Google, Microsoft or other third-party platforms.
Technical & Integrations
The difference between on-premise and cloud is that an on-premise system runs on the company’s own hosting, with full control of the data, while a cloud system runs on the vendor’s servers and is accessed over the internet.
The choice affects cost, data control and compliance, with an on-premise CRM offering full ownership.
CRM Fundamentals
Onboarding is the process of initial setup and adoption of a new system (CRM) by a team, including installation, data import and user training.
Good onboarding shortens the time until the team becomes productive with the new software.
Sales & Leads
An opportunity is a qualified lead with a real probability of turning into a sale, actively tracked in the pipeline.
Algorithms in a CRM automatically identify the most promising opportunities, helping the team prioritise correctly.
ERP & Architecture
Procurement is the process of buying the materials, products or services a company needs for its activity.
In an ERP, the procurement module manages orders to suppliers and links them to stock.
Technical & Integrations
A production environment is the real, live system used daily by users, containing the company’s real data.
Unlike a sandbox, any change in the CRM’s production environment directly affects real work.
Finance & Invoicing
A proforma invoice is a preliminary document showing the details of a proposed transaction (products, prices, terms) before the final tax invoice is issued.
In a CRM, the proforma is generated directly from the quotation and can be converted automatically into a tax invoice once payment is confirmed.
Technical & Integrations
A query is a request to the database to extract or filter specific information.
Reports and filters in a CRM are based on queries over the client and sales database.
Sales & Leads

The CRM tracks progress against quota in real time, motivating the team and keeping it accountable.
Sales & Leads
A quotation is the commercial proposal sent to a client, detailing products or services, prices and terms.
CRMs generate professional PDF quotations directly from the opportunity record and email them automatically, tracking their status.
Technical & Integrations
Rate limiting restricts the number of requests an application can send to an API in a given time, to prevent overload.
CRM integrations must respect the rate limits of external platforms to work reliably.
Sales & Leads
A recall system automatically reminds the team to contact a client again at the right time, for example for a periodic check-up or a renewal.
Recall in a CRM increases retention and recurring revenue through timely follow-up.
Technical & Integrations
A relational database organises data in tables linked by relationships, allowing complex queries and high integrity.
Most CRMs use relational databases (such as MySQL) to link clients, quotations and invoices.
CRM Fundamentals
A reminder is a scheduled alert that tells the team about an action or deadline, shown as a pop-up or notification at the set time.
Smart reminders in a CRM prevent missed calls, quotations or important follow-ups.
Technical & Integrations
A required field must be filled in before a record can be saved in a CRM.
Required fields make sure essential data, such as a lead’s name or phone number, is never missing.
Technical & Integrations
A REST API is a standard type of programming interface that lets applications communicate through simple HTTP requests (GET, POST, PUT, DELETE), usually using JSON.
Modern CRMs expose a REST API so developers can integrate the system with other platforms and automate data flows.
Technical & Integrations
Roles and permissions are the settings that control what each user can see and do in a CRM, limiting access to sensitive data according to job role.
For example, an agent can see only their own leads, without the right to export the company’s whole database.
Sales & Leads
A sales cycle is the average time from first contact with a lead to closing the sale.
Shortening the sales cycle, tracked in a CRM, means faster revenue and a more efficient sales process.
Sales & Leads
A sales funnel is the model describing a prospect’s path from first contact to purchase, narrowing as uninterested leads drop out.
Unlike the pipeline (the internal view of stages), the funnel describes the audience’s buying behaviour.
Sales & Leads
A sales pipeline is the visual representation of the stages a sales opportunity goes through, from first contact to closing the sale.
Typical stages are: New lead, Contacted, Quotation sent, Negotiation and Won. A clear pipeline shows exactly where sales get stuck.
Sales & Leads
A sales territory is a geographic area or market segment assigned to an agent or team.
In a CRM, dividing by territory avoids overlaps and ensures full market coverage.
Sales & Leads
Sales velocity is the speed at which opportunities move through the pipeline and generate revenue, combining the number of deals, average value, win rate and cycle length.
A CRM calculates sales velocity to show how quickly sales effort turns into money.
Technical & Integrations
A sandbox is an isolated test environment, identical to the real one, in which you can try configurations and integrations without affecting production data.
Developers use the CRM sandbox to test new workflows before enabling them for real clients.
Technical & Integrations
Scalability is a system’s ability to handle a growing volume of data and users without a drop in performance.
A scalable CRM supports business growth, letting you add users and records without redesign.
Sales & Leads
Segmentation is the process of dividing the client base into groups with common characteristics (industry, budget, behaviour, location), in order to send them relevant messages and offers.
A CRM allows automatic segmentation and targeted campaigns for each segment.
Technical & Integrations
A self-hosted (on-premise) CRM is a system installed on the company’s own hosting, where all data stays stored locally under full control, usually with a one-time licence instead of a monthly subscription.
The opposite is a cloud (SaaS) CRM, where data sits on the vendor’s servers.
Technical & Integrations
An SLA (Service Level Agreement) defines the guaranteed level of service, such as availability or support response time.
When buying a CRM, the SLA sets clear expectations about support and platform reliability.
Sales & Leads
An SQL (Sales Qualified Lead) is a lead validated by the sales team as ready for a direct sales conversation.
The move from MQL to SQL in a CRM marks the moment marketing hands the lead over to sales.
Technical & Integrations
SSO (Single Sign-On) lets a user sign in once and access several applications without entering the password again.
In business environments, SSO simplifies the team’s access to the CRM and other connected tools.
Technical & Integrations
Stock management means tracking available product quantities, linked to sales and services, with automatic alerts when stock runs out.
Integrating stock into the CRM centralises inventory movements in the same interface as sales.
Technical & Integrations
A tag is a short label attached to a client, lead or opportunity to classify and filter them quickly.
Tags in a CRM allow flexible organisation of contacts by your own criteria, such as source, interest or priority.
CRM Fundamentals
Task management is organising and assigning tasks to team members, with each task’s status tracked in real time.
In a CRM, tasks are linked directly to clients and opportunities, so no important action is forgotten.
Technical & Integrations
A template is a reusable predefined model for documents, emails or quotations, filled in automatically with the client’s details.
Templates in a CRM speed up the generation of repetitive documents and keep a consistent look.
CRM Fundamentals
Ticketing is the system through which client requests are recorded as individual tickets, prioritised and tracked until resolved.
The support module in a CRM centralises tickets and sends automatic notifications, giving the team full control over requests.
ERP & Architecture
Timekeeping is the record of hours worked by employees, used for payroll and management.
A timekeeping module integrated into a CRM/ERP automates the tracking of staff attendance and hours.
Sales & Leads
A touchpoint is any interaction between a client and the company, from an email or call to a website visit.
The CRM records all touchpoints, giving a complete picture of the customer journey.
Technical & Integrations
A trigger is a condition that automatically starts an action, for example sending an email when a lead reaches a certain stage.
Triggers are the basis of CRM automations, linking events to predefined reactions.
Technical & Integrations
Two-way synchronisation means data updates automatically in both directions between two systems, so a change in one is reflected instantly in the other.
In a CRM, two-way synchronisation with the calendar or invoicing platform keeps information consistent everywhere.
Finance & Invoicing
A CRM with unlimited users lets you add any number of agents, operators or managers without the licence price going up.
It is the opposite of the classic SaaS model, where every new user increases the monthly bill and limits team growth.
Sales & Leads
Upselling is the technique of offering a client a higher or more complete version of the product they intend to buy.
A CRM identifies upselling opportunities based on each client’s history and profile.
Technical & Integrations
Uptime (availability) is the percentage of time a system is working and accessible, a key indicator of reliability.
For a self-hosted CRM, uptime depends on the company’s own infrastructure, giving direct control over reliability.
Technical & Integrations
A VPS (Virtual Private Server) is a virtual server with dedicated resources, isolated from other users of the same physical machine.
A self-hosted CRM can run on a VPS, offering control and security at an affordable cost.
ERP & Architecture
A stock location is a storage unit (warehouse, shop) in which product receipts and issues are tracked.
An ERP manages several stock locations at once, giving a consolidated view of stock.
Technical & Integrations
A webhook is a mechanism through which one application automatically sends data to another the moment an event occurs, without the second having to check periodically.
In a CRM, webhooks trigger actions instantly, for example creating a lead as soon as a form is filled in on the website.
Technical & Integrations
The difference between a webhook and polling is that a webhook sends data automatically when an event occurs, while polling means an application periodically checks for new data.
Webhooks are more efficient for a CRM, because they update information instantly, without unnecessary repeated requests.
Sales & Leads
Win rate is the percentage of opportunities won out of all those tracked in a period.
Tracking win rate in a CRM shows the sales team’s efficiency and the quality of leads.
Technical & Integrations
A workflow is a predefined sequence of steps and automatic actions triggered by certain conditions or events.
In a CRM, workflows automate processes such as sending a quotation after a lead is qualified or an email after an order is completed.
