Accounting mapping rules
Decide per invoice line on which ledger account, VAT code and dimensions your accounting package books it, beyond the pricing category codes.
Updated October 13, 2026
Without rules, an invoice line is booked on the Credit code or Debit code of its pricing category and the codes of its tax rate. Accounting mapping rules let you choose other codes per situation, for example a separate revenue account for customers outside the EU, a cost center per team or a project per customer. The rules are used by the accounting connectors for Exact Online, Twinfield, AFAS, Moneybird, SnelStart, e-Boekhouden and QuickBooks.
Create a rule
- Open Settings, click the Variables tab and go to Accounting mapping rules.
- Click New rule.
- Under General, enter a Name and leave Active on.
- Under When does the rule apply?, fill in only the conditions you need: the Accounting integration (empty: all), the administration, the Invoice type (Sales and purchase, Sales invoices or Purchase invoices), Pricing categories, teams, customers or suppliers, Countries of the customer / supplier (country codes such as DE, NL), Customer / supplier in the EU, Transport modes and VAT categories. All filled-in conditions must hold.
- Under Where is the line booked?, enter the Ledger account and/or the VAT code, in the same format as the codes of your pricing categories. Empty fields keep the pricing category and tax rate codes.
- Optional: click Add dimension and enter the Dimension and its Code, for example a cost center. A rule has at most 10 dimensions.
- Click Save.
Supported dimensions: Exact Online CostCenter and CostUnit, Twinfield dim2 and dim3 (cost center and project), AFAS DiC1 and DiC2, QuickBooks class and department. Moneybird, SnelStart and e-Boekhouden only use the ledger account and VAT code.
Put the rules in order
Rules are checked from top to bottom, and the first active rule that matches a line wins. Drag a rule to change the order, or use Move up and Move down. Put specific rules above general ones.
Test the rules on an invoice
- Click Test on an invoice.
- Find the invoice in Search an invoice.
- Click Test.
- For every line, read the ledger account, VAT code and dimensions, and under Decided by which rule set them, or Pricing category codes when no rule matched.
Testing saves and sends nothing. Changed rules apply to invoices sent to your accounting package from then on.
