Your Own Multi-Client Cloud Accounting Firm in a Box
Fully Managed, 100% Private per Client, Powered by AI — Built for Belgian Accountants and Firms
Your Country's Compliance, Built In
| Filing | Frequency | What's actually automated |
|---|---|---|
| VAT (Intervat) | Monthly / quarterly | Generates the full Belgian VAT return on a free-tier OCA stack, validated against the current Intervat schema (2026/2) using real invoice data. |
| DmfA (social security) | Quarterly | Custom-built XML generator covering both blue-collar (PC112) and white-collar (PC200) joint committees — correct ONSS contribution rates, full/part-time detection, and legally-mandated holiday-pay handling, generated from the employee contract terms you enter directly in Odoo. |
| Précompte professionnel | Monthly / quarterly | Full withholding-tax bracket (barème) calculation across all five marital-status categories plus dependent-children reductions, generated from Odoo payroll data and validated against the official withholding schema. |
| Belcotax (fiche 281.10) | Annual | Full annual fiscal certificate generation, correctly handling multi-word Belgian surnames and official checksum validation, tested against real employee records. |
Every filing is generated and schema-validated, ready for your accountant's review and confirmation before they upload it manually to the relevant government portal.

- Support for the bundle itself, not just the servers
- True Client Isolation — each of your clients operates in its own dedicated, private environment with its own web/app portal.
- Intelligent Intake — AI agents read multilingual documents uploaded via web or app and calculate tax splits; VAT numbers are format-validated.

- No More Manual Bookkeeping — you no longer enter data by hand. Every entry is automated and traceable back to its source document; your role shifts to review and sign-off in Odoo.

| Filing | Frequency | What's in progress |
|---|---|---|
| VAT (i.SAF) | Monthly | Full field-level mapping complete — every i.SAF field (Header, MasterFiles, Sales/Purchase Invoices, Settlements) mapped directly to Odoo's invoice data. Currently building the tax-code lookup against VMI's official PVM classifier and the XML generator itself. |
| FR0600 (preliminary VAT declaration) | Monthly | Built on top of i.SAF via the i.MAS preliminary-declaration path, with a mandatory human review step before EDS submission — the same "generate, verify, sign off" model used in Belgium. |
| Sodra payroll (SAM) | Monthly | Salary and contribution data computed directly in Odoo, not spreadsheets, using the same deterministic-generator architecture as Belgium's DmfA — no AI in the number-generation path. |
Built on the same core principles as the Belgium bundle: deterministic generation, schema-validated against VMI's official specs, and submission always stays a manual step for your accountant.

The Manual Work Behind Every Set of Books, Handled for You
Each of your clients uploads invoices, receipts and cash register entries through their own private web and mobile portal. The system matches them against bank statements and prepares VAT, DmfA and payroll reports — ready for you to review and file. Fully managed and hosted for you, monitored 24/7, with weekly checkups included.
Three Systems, Working as One
You don't manage three separate products. You get one working process — we handle everything underneath it.
Reads the Documents
Each client uploads invoices and receipts through their own private web and mobile portal — an AI agent reads them, even handwritten or paper receipts, and turns them into structured data.
Moves & Matches the Data
Automation pulls bank statements and matches every transaction against the right invoice, automatically.
Books It & Reports It
Everything lands in Odoo, ready for your review — including monthly reports, VAT and DmfA filings, and payroll from the contract terms you entered directly.
Your Client vs. You
Clear division of labor: your client enters the day-to-day data through their own Portal, you handle the parts that require professional judgment and file with the authorities.
Your Client (via Portal)
- Uploads invoices & bills
- Enters cash & card takings, uploads bank statements
- Adds/updates employees (except wage, INSS, joint committee, contract dates)
- Logs staff hours, runs payroll (draft)
- Views and downloads reports
You (in Odoo)
- Set salary structure, joint committee and wage on new contracts
- Reconcile anything the bank import couldn't auto-match
- Confirm payslip batches before they're final
- File VAT, DmfA, withholding tax and Belcotax with the authorities
- Reset your client's password if they lose it (admin access stays with Cloud Acropolis)
Ready for Mandatory Peppol E-Invoicing
From 2026, structured electronic invoicing via the Peppol network becomes mandatory for B2B transactions in Belgium. Your accounting bundle is built to handle this from day one — no separate tool, no manual XML wrangling.
- Incoming and outgoing invoices processed in UBL/XML format via the Peppol network
- Full integration with Odoo — Peppol invoices flow straight into your books, no double entry
- Automated validation, routing, and error handling behind the scenes
Enterprise-Grade, Without an IT Department
Private & Secure by Design
Every client gets their own dedicated, isolated, EU-hosted environment — never shared, never mixed with another client's data.
You Stay in Control
The system prepares the books and drafts the reports. You review, sign off, and file. Nothing is submitted anywhere without you.
Belgian Rules, Built In
VAT, DmfA and payroll rules pre-configured from day one — not a generic template you have to adapt yourself.
New Clients Onboarded in Minutes
Adding a new client to your package takes under 20 minutes, start to finish — no lengthy setup project.
Managed & Monitored 24/7
Our team watches your infrastructure around the clock. Weekly checkups, patch updates and monitoring are included — you never touch a terminal.
Built for Accountants, Not Developers
No coding, no command line, no in-house IT required. Send a message, enter a contract — that's the whole interface.
How Many More Clients Could You Take On?
Estimate the time freed up per client, and how many more clients you could serve with that same time — without hiring.
Based on published AP processing benchmarks: manual pre-accounting averages ~12 minutes per invoice (IOFM/Ardent Partners AP benchmarking), vs. ~1.2 minutes per invoice with AI-native automation, a ~90% reduction (Nexus AP research). Actual results vary by client and document complexity.
9 Layers of Security, on Every Client's Data
Financial records deserve more than a shared spreadsheet. Every client's data is isolated, encrypted, and protected by the same infrastructure banks and enterprises rely on.
Every link and file handled by your bundle is checked by our URL Security Monitor before it ever reaches your infrastructure. Combined with real-time antivirus, double-encrypted storage and daily backups, your financial data stays protected without you having to think about it.
Technical details, for your IT team
Each client gets their own isolated environment, running Odoo (books and reports) with an AI-assisted document intake and matching layer. Every client's data is separated at the database level — nothing is shared between clients.
| Storage | 100 GB (Accountant 1) / 300 GB (Accountant 2) / 1,000 GB (Accountant 3) total, EU-hosted enterprise storage |
| Support | 3-hour MTTR, via email ([email protected]) |
| Deployment | Isolated environment per client, own URL and login, EU-hosted |
| Backups | Daily, EU-hosted, encrypted at rest |
AI-assisted preparation with final human validation by the certified accountant. Cloud Acropolis prepares and validates data for submission; final filing remains the accountant's professional responsibility.
Frequently Asked Questions
Common questions from Belgian accountants and accounting firms.
Yes. Our custom DmfA XML generator explicitly covers both blue-collar (PC 112) and white-collar (PC 200) joint committees, with correct ONSS/RSZ contribution rates, full-time/part-time detection, and legal holiday pay handling.
Yes. VAT declarations are generated and validated against the current Intervat schema (2026/2) using your real invoice data, then handed to your accountant for review before submission.
All data is hosted on 3 dedicated, EU-based servers protected by a 9-layer security stack. Only your authorized team and CloudAcropolis's managed-service engineers have access.
No. Every declaration is generated and schema-validated automatically, but final submission to Intervat, DmfA, or Belcotax always remains a manual, deliberate step performed by the accountant.
Onboarding a new client takes under 20 minutes. The system comes pre-configured with Belgian tax and payroll rules from day one.
Pre-accounting automation uses AI and workflow tools to read invoices, receipts, and bank statements automatically, matching them against the right ledger entries and preparing VAT, DmfA, and payroll data for an accountant's final review — reducing manual data entry without replacing professional oversight.
In Belgium, pre-accounting automation reads documents uploaded via each client's private web and mobile portal, extracts invoice and VAT data, matches it against bank transactions, and prepares Intervat VAT declarations and DmfA filings in the correct format — ready for the accountant's review before submission.
Beyond the standard bank sync, we can build integrations with other banks, or connect to your firm's own internal systems and portals. This is custom scope work — get in touch to set up a call and define what you need.
