Why Odoo 18 matters for Belgian SMEs

Belgian legislation around accounting and VAT continues to evolve.
Companies must report faster, invoice more accurately, and collaborate more digitally with clients and suppliers.

Odoo Accounting responds to this with:

1. Automatic VAT returns that follow Belgian rules
2. Real-time dashboards for cash flow and profit
3. Integrated Peppol e‑invoicing and bank syncing

For SMEs in construction, logistics, consulting, retail, marketing or IT, this means more control, fewer mistakes and a more professional approach.

The 9 best new accounting features in Odoo 18

1. Improved VAT codes tailored to Belgian rules

Odoo 18 supports all specific Belgian VAT regimes, including reverse-charge, intra-community deliveries and exemptions. Reports now align automatically with the declaration format of the FPS Finance.

2. Peppol e‑invoicing built-in by default

Send and receive electronic invoices directly via the Peppol network. No need for extra tools. Perfect for working with government clients or large businesses.

3. Automatic recognition of incoming invoices

Thanks to built-in AI, Odoo now scans PDF invoices and recognizes amounts, suppliers, VAT codes and booking rules. Less manual work and faster processing.

4. One-click smart bank reconciliation

Odoo suggests automatic links between bank transactions and invoices. With a single click, you can confirm dozens of payments and receipts—saving hours every month.

5. Cash flow forecasting based on real and expected data

The new cash flow report combines outstanding invoices, recurring expenses and bank balances. Ideal for predicting surpluses or shortfalls in advance.

6. Budgeting per project, client or department

Set budgets for each project or team, and automatically track deviations. Useful for consultancy, IT and marketing firms that report by client.
