IT services for accounting
firms in Reunion Island
Chartered accountancy firms, statutory auditors, approved management centres — your IT requires a provider who masters Sage, Cegid, FEC retention and high availability during tax season. ECLAUD IT supports accounting professionals in Reunion Island.
49% of French businesses experienced at least one successful cyberattack in 2023 (CESIN). Accounting firms are priority targets: they hold the financial, tax and payroll data of hundreds of clients. 10-year FEC retention, mandatory electronic invoicing, 8 in 10 attacks involve ransomware, phishing or account compromise. ECLAUD IT secures and manages IT for accounting firms in Reunion Island.
Why does your accounting firm need a specialist IT provider?
An accounting firm is not a standard office. You manage the financial, tax and payroll data of dozens — sometimes hundreds — of clients. Sage, Cegid and QuadraExpert run in client/server architecture on critical databases. A failure on 15 April means the production of tax returns comes to a dead stop.
We see the same scenario repeatedly: a generalist technician installs an antivirus, makes a backup to an external hard drive and leaves satisfied. But they do not know that the FEC must be retained for 10 years in a standardised format. Nor that Sage requires a regulatory update before each payroll deadline. A poorly planned Windows update can lock access to Cegid databases for several hours — right in the middle of year-end close.
"8 in 10 cyberattacks against accounting firms fall into three categories: ransomware, phishing and account compromise. Financial data is the most lucrative target after health data." — Cegid, Accounting firm security report 2025
60% of small businesses that suffer a cyberattack close within 6 months (Senate report). For an accounting firm, the loss of client data is not just a technical incident: it triggers a professional body investigation, a mandatory CNIL notification, and the task of rebuilding client trust. The Order of Chartered Accountants has joined the GIP Cybermalveillance programme to strengthen cybersecurity across the profession.
What FEC retention and compliance obligations apply to accounting firms?
10-Year Retention
Accounting records (ledgers, journals, supporting documents, FEC) must be retained for 10 years from the end of the financial year. A legal obligation: Article L123-22 of the Commercial Code. Applies to digital backups.
FEC — Accounting Entries File
The FEC must be provided to the tax authority upon request, in a standardised format. The mandating accountant assumes responsibility for retaining it for 10 years. Loss of the FEC represents a major risk during a tax audit.
Electronic Invoicing
Progressive obligation from 2024 for large companies, extended to all businesses by 2026. Accounting firms manage their clients' invoicing flows — their IT infrastructure must support PDPs (Partner Dematerialisation Platforms).
Which accounting software does a specialist IT provider support?
Every firm has its own ecosystem. Some have been on Sage for 15 years, others have migrated to Cegid Expert, others use QuadraExpert with Silae for payroll. We know these architectures. Installation, regulatory updates (contribution rates, tax brackets, DSN, collective agreements), backup, support — everything is covered.
| Software | Type | Profiles |
|---|---|---|
| Sage (50, 100, 1000) | Accounting, payroll, commercial management | Firms and businesses — French market leader |
| Cegid Expert / ACD | Accounting production, review, tax returns | Chartered accountancy firms |
| QuadraExpert (Cegid) | Bookkeeping, review, tax filings | Firms — historically very established in France |
| EBP Compta | Accounting and invoicing | Micro-businesses and small firms |
| Dext (ex Receipt Bank) | Document digitisation and OCR | Firms — automated document collection |
Payroll & HR — Sage Paie, Cegid, Silae

A contribution rate not updated, a rejected DSN, a payslip sent with the wrong tax bracket: the consequences for your clients are immediate. Our role is to ensure your payroll environment is stable, up to date, and that you never discover a problem on the 5th of the month.

Accounting firm IT in Reunion Island — local specificities
Reunion Island has more than 200 chartered accountancy firms and approved management centres. The sector is dense. IT providers who truly know Sage client/server or FEC obligations are rare. Most firms end up relying on an occasional technician — competent on workstations, but not on the profession-specific constraints.
We are based in Saint-Paul. That means same-day on-site intervention and knowledge of island-specific constraints — latency to Cegid cloud servers in metropolitan France, dependence on undersea cables, need for a local backup that takes over when the connection drops. This is not the same as managed IT delivered from Paris.
We support Reunion Island firms through the digital transition: dematerialisation, electronic invoicing, securing remote access for team members working from home. The electronic invoicing reform directly affects your clients — it is better to be prepared.
How much does managed IT cost for an accounting firm?
| Firm type | Workstations | Monthly range |
|---|---|---|
| Solo / small firm | 3–5 workstations | EUR 200 — 450/month |
| Mid-size firm | 10–25 workstations | EUR 49 — 89/workstation/month |
| Large firm / group | 25–80 workstations | Custom quote (dedicated infrastructure) |
All plans include: unlimited support, compliant backup (FEC 10-year retention), managed antivirus, business software updates, 24/7 monitoring. Tax season on-call service available as an option. On-site interventions in Reunion Island are included.
FAQ — Accounting firm IT services
Why choose a specialist accounting IT provider rather than a generalist?
An accounting firm uses complex business software (Sage, Cegid, QuadraExpert) with frequent regulatory updates (DSN, contribution rates, collective agreements). A specialist provider knows this software, its client/server architectures, and the legal retention requirements. A generalist risks misconfiguring the FEC backups or mishandling a critical Sage update during the tax season.
How do you protect client data during the tax season?
The tax season (January to May) is the most critical period: any IT failure stops the production of balance sheets and tax returns. ECLAUD IT implements enhanced backups (RPO < 4h during tax season), 24/7 server monitoring, and a tested business continuity plan. We verify Sage/Cegid updates BEFORE the season to avoid unpleasant surprises.
Do my backups comply with the 10-year retention obligation?
With ECLAUD IT, your backups are encrypted, stored on servers in France, and retained according to a schedule compliant with Article L123-22 of the Commercial Code (10 years). We archive each year's FEC separately and test restoration quarterly. A compliance report is provided for your professional body obligations.
What happens if my Sage server fails during the year-end close?
Our disaster recovery plan (DRP) provides an RTO of less than 4 hours for accounting firms. In the event of a server failure, we restore your Sage/Cegid environment on a standby server. During the tax season, we activate a dedicated on-call service with priority intervention. 60% of SMEs that suffer a major failure without a DRP cease operations within 6 months.
What does managed IT cost for an accounting firm?
For a firm of 3–5 workstations, expect EUR 200 to 450/month all-inclusive (unlimited support, backup, antivirus, business software updates). For a firm of 10–25 workstations, the range is EUR 49 to 89/workstation/month. The investment is tax-deductible and replaces hiring an in-house technician.
Does ECLAUD IT handle mandatory electronic invoicing?
Yes. We support firms through the transition to electronic invoicing: choice of PDP (Partner Dematerialisation Platform), configuration of inbound/outbound flows, integration with Sage or Cegid. The obligation is being rolled out progressively to all businesses — your clients are counting on you to be compliant.
Does ECLAUD IT serve accounting firms in Reunion Island?
Yes, we are based in Reunion Island (Saint-Paul) and serve the entire island. We support several Reunion-based chartered accountancy firms — from 3 to 25 workstations. On-site intervention within 4 hours, unlimited remote support.
