The object of the agreement and the validity of the document

This certificate governs the level of technical assistance and stability patches provided as a matter of obligation by the engineering team in our division. Unlike the rigid systems rented in the cloud (SaaS), buying our perpetual licence represents an asset of your own.

CRM system

The warranty covers the integrity of the source code delivered and the sound operation of the core modules. Because this is installed privately (self-hosted), full autonomy is assured, and absolute control over your data is protected for life.

Zero Downtime Framework

The system includes a protocol of , running structural SQL verification routines silently at every initialisation. When versions change or are updated, the platform auto-migrates its tables in the background, eliminating unforeseen errors and the need for manual intervention by an outside programmer.

Warranty clauses

What the technical warranty covers, clause by clause

The eight clauses below set out the technical coverage committed to for installations under warranty.

2. Resilient security and the anti-data-loss guarantee

The level of security is a structural priority in every implementation. We guarantee you specialised technical assistance for isolating the databases correctly and securing the commercial perimeters, with data protection built in by design.

All internal transactional operations, lead conversions and major financial changes are carried out under the atomicity protection shield (native SQL transaction commands). In the event of an unforeseen error or a network fault, the system triggers an automatic rollback, preserving structural consistency. This instantly cancels any fragmented write, returning the database to its previous stable state.

  • Local backup routines: During onboarding, our specialists configure automated periodic backup scripts (daily/weekly) with secure storage on isolated secondary volumes.
  • End-to-end encryption and company lookup: All API flows transmitted are secured through advanced SSL/TLS protocols. Registering new companies uses a secure anti-duplicate system that blocks the saving of polluted or overlapping data.
  • Cascading clean deletion: Deleting data on request follows a strict 8-step protocol, physically deleting orphaned files from the disk while preserving the mathematical integrity of the overall financial reports through intelligent decoupling.
3. Maintaining tax compliance (API synchronicity)

A major component of the technical warranty is maintaining a live connection with the administrative invoicing channels. We commit contractually to developing and delivering corrective patches where legislative changes require code restructuring.

The system automatically performs a reverse mathematical reconstruction for VAT and net price down to the fils. To guarantee a stable connection with third-party cloud servers, the platform includes a special structural sanitisation function for input data, removing invisible Unicode characters picked up accidentally by copy-paste and preventing blocked 401 Unauthorized errors.

e-invoicing specification: This CRM application is interconnected through a dedicated API with the accounting system you use. The technical warranty covers keeping these API bridges working, ensuring that any tax document generated from the sales pipeline is submitted automatically to the e-invoicing system, with no manual intervention and no risk of desynchronisation. Once the document receives its official tax number, the system automatically blocks local editing to ensure full compliance before the law.

4. The incident protocol and reaction times (response matrix)

Technical reports are submitted through the secure channels (ticketing system or premium email). The contractual intervention and remediation times are classified strictly by the severity of the incident.

For incidents of maximum severity, the platform activates an automatic protocol called Least-Loaded Agent Assignment, which queries the database in real time and passes the ticket to the operator or engineer with the lowest active workload. At the same time, a live countdown starts (SLA Countdown Ticker) on the technician’s monitor, pulsing visually on screen to force resolution of the crisis.

The response and resolution times for each severity level are in the table in the SLA indicators section.

5. Synchronisation guarantee for the sales and e-commerce module

The technical warranty covers maintaining the asynchronous communication bridges for online shops (WooCommerce and PrestaShop). All leads and orders captured by webhook benefit from high-speed processing with no packet loss.

  • Flawless stock reservation: The system runs a native instruction that records stock movements in the logical register, preventing phantom stock from being locked.
  • Duplication protection: Consecutive generation of quote numbers blocks the issuing of duplicate documents during simultaneous agent actions.
6. Protection of the HR module, automatic attendance and IP location

The automated three-state attendance system is protected contractually against the accumulation of fictitious hours through asynchronous activity monitoring algorithms.

  • Idle Detector Framework: If an employee records 20 minutes of complete inactivity at peripheral level, the clock is forced to stop automatically, storing the real working value.
  • Validated IP geolocation: The system checks the IP address at every check-in, applying the correct Office or Remote label automatically, with no possibility for ordinary users to fake the reports.
7. Reputation automation and critical emergency escalation

The Reputation Management module acts as a shield for the brand. AI semantic analysis algorithms scan client reviews in the background and can instantly tell promoters from detractors according to strict corporate NPS® standards.

Where a client gives feedback below 3 stars, an automatic critical ticket is guaranteed to open asynchronously in the helpdesk, assigned with priority to the least busy manager, and the SLA intervention clock starts with a maximum of 2 hours.

8. Cryptographic traceability and document preview

The public split-screen online signing portal guarantees the capture of unique digital fingerprints at every contracting. Every file generated receives a secure SHA-256 mathematical key that validates the integrity of the legal document.

Smart Attachment Suppression technology holds back the physical PDF until both parties have applied their handwritten signature on the digital canvas, delivering the final secured document only when the transaction is perfectly concluded by both sides.

9. Infrastructure boundary and official validation

Hardware maintenance of the physical server or the private VPS on which the platform runs is the responsibility of the hosting provider chosen by the client or of the internal IT department. Our team guarantees exclusively the maintenance, troubleshooting and continuous updating of the software layer.

Frequently asked questions

Answers about the technical warranty

The severities, the deadlines and what is and is not within the contractual coverage.

How quickly do I get a reply to a critical report?
For severity S1 — platform entirely blocked, system offline — the committed response time is under 2 hours, and resolution is guaranteed in under 12 hours.
What are the severity levels?
Three: S1 — critical, the platform entirely blocked; S2 — major, an error on a specific module, for example the invoicing API or a blocked webhook; S3 — standard, minor adjustments, interface optimisations and everyday usage questions.
How long does fixing an error on a single module take?
For severity S2 the response time is under 6 hours, and resolution is guaranteed in under 24 hours.
How are technical reports submitted?
Through the secure channels provided in the agreement — the ticketing system and the contact addresses communicated at implementation. The incident protocol and the reaction times are detailed in clause 4.
What happens to requests for adjustments or optimisations?
They fall under severity S3, with a response in under 24 hours. Resolution is planned in the sprint pipeline; it has no fixed guaranteed deadline, because it does not affect how the platform works.
Which infrastructure does the warranty apply to?
To the client’s private infrastructure, where the platform is installed. The division of responsibilities between supplier and client is described in clause 9.
Does the warranty also cover tax compliance?
Yes. Maintaining connectivity with the tax systems is the subject of clause 3 on tax compliance and API synchronisation.
Where is the agreement valid?
The applicable jurisdiction is UAE / Global, per the agreement details above.
