Odoo Accounting Consultant, Belgium

Belgian VAT grids and listings, line by line

The Belgian VAT return is organized around numbered grids, and Odoo produces it from tax grids attached to each tax. A tax linked to the wrong grid, or a credit note that does not reverse the right grid, gives a report that looks plausible and is quietly wrong. Because the Belgian localization does much of the setup for you, it is tempting to trust it. I prefer to verify.

For each tax I record the target grid for the net amount and for the VAT amount, separately for invoices, bills and credit notes. Your accountant prepares expected figures for a set of sample documents covering domestic sales at each rate, intra-EU supplies of goods and services, reverse charge purchases, imports, exports and any special regime they identify. We run those documents through a sandbox and compare the report with the expected values.

Listings depend on contact data. The intra-EU listing needs valid VAT numbers and country codes, and the annual customer listing needs Belgian customers' enterprise numbers. Missing identifiers block go-live, and a recurring control catches gaps on newly created contacts. How each transaction is treated and filed stays with your accountant. Edition and implementer questions sit on my freelance Odoo consultant in Belgium page.

CODA statements and reconciliation models

Belgian banks commonly supply statements in CODA format, and Odoo can import CODA files, subject to your edition and modules. Importing is the easy part. The time saving comes from reconciliation models, which decide what happens to each line once it arrives.

I design those models from a sample of your real statements. Customer receipts that carry a structured payment reference can be matched to the corresponding invoice automatically. Receipts with a free-text reference need a looser rule, usually based on invoice number or amount and partner, with a suggestion for the user to confirm. Bank costs, card terminal settlements, loan repayments, insurance and recurring utility debits each get a model that books the entry directly or proposes it.

We then run several weeks of real statements through a sandbox and measure how many lines remain for manual handling. The models are tuned until that remainder is mostly genuine exceptions. I also document what users should do with unmatched lines and how often, because a small backlog left for a month becomes a large one. For outgoing payments, SEPA files generated from Odoo are tested with your bank before go-live. The product view of reconciliation is on Odoo Accounting.

Payroll journals from the social secretariat

In Belgium, payroll is commonly run by a social secretariat rather than inside the ERP. Each month the secretariat produces salary figures and a journal, and finance has to post them correctly: gross pay, employer contributions, withholding tax, net pay to employees and amounts due to the secretariat itself. If this is done by hand from a PDF, errors creep in and analytic reporting by department suffers.

Odoo can import payroll journals in a structured format in some Belgian setups, depending on edition, modules and the secretariat's export. I check what your secretariat provides, whether Odoo can read it directly and, if not, design a simple import template. Each line maps to an agreed account, and where you report costs by department, project or site, the analytic distribution is defined as part of the mapping.

A monthly check compares the posted totals with the secretariat's summary before the period is locked. Payments of net salaries and amounts due to the secretariat are then reconciled through the bank like any other line. This keeps payroll costs visible in management reports without bringing payroll calculation itself into Odoo, which stays with the specialists. Integration options are covered under ERP integration.

Intercompany and the edition question for finance

Belgian business owners frequently hold an operating company alongside a management company, a real estate company or foreign subsidiaries. Those entities can share one Odoo database: books and taxes stay separate per entity, while catalog items or contacts are shared only if you choose. I agree with your accountant which companies belong together and which data each user may see.

Intercompany flows such as management fees, rent, recharges and loans should be booked symmetrically. Odoo Enterprise can create the counterpart document in the related company automatically; without that feature, finance books both sides manually via clearing accounts and agrees the balances at month end, which works when one person is clearly responsible. If companies form a VAT unit, ask your accountant how the combined return will be prepared and I configure reporting to support their method.

Group consolidation is often prepared by the accounting firm outside Odoo, fed by clean trial balances. On edition: Community can work for straightforward invoicing with a developer behind it, but CODA import, reconciliation tools, intercompany automation and supported localization updates usually point to Enterprise for a Belgian finance team. I compare both against your requirements. See multi-company ERP for broader design questions.

Working with the accounting firm and the implementer

A Belgian Odoo accounting project involves several parties: your finance staff, the external accounting firm that files returns and prepares annual accounts, the implementation firm responsible for configuring and supporting Odoo, and the social secretariat for payroll. Each has a piece of the picture, and gaps appear between them. My role is to hold the finance requirements together and make sure each party's output fits the next.

That means a written finance requirements document before configuration, a test plan built from Belgian scenarios, a sign-off by your accountant after reviewing results, and a log of issues tracked to closure. I also review the opening balance load and the first live VAT return preparation, which are the moments where small mistakes become lasting ones.

Filing, tax opinions and the annual accounts stay with your accounting firm. If Odoo turns out to be wrong for your finance needs, I say so. Broader system choices are handled through ERP consulting in Belgium, with background on the Belgium hub, while my testing and UAT service sets out how sign-off works.
