Purchase and sales invoices

Enter an invoice or a credit note net of VAT with its VAT codes; NovaFisko generates the VAT and the third-party counterpart.

Updated on 10/05/2026 Edit this page

The Invoice tab is used to enter a purchase invoice, a sales invoice or a credit note the Belgian way: you enter the amounts excluding VAT and the VAT code of each line, and NovaFisko computes the VAT, creates the VAT lines and the counterpart of the customer or the supplier.

Entering an invoice

  1. Open Invoice.
  2. Choose the Journal. Its type sets the nature of the document: ACH for a purchase, VEN for a sale, NCA or NCV for a credit note.
  3. Choose the Supplier or the Customer. If it does not exist, create it with New third party without leaving the screen.
  4. Enter the Invoice date and, if you know it, the Due date.
  5. Enter the Supplier invoice no. (or Invoice no.), the Structured reference and optionally a label.
  6. Enter the Total amount incl. VAT: it serves as a check during allocation.
  7. For each line, choose the Account, enter the Net amount and check the VAT code.
  8. Add other lines with Add a line until the To allocate indicator is at zero.
  9. Click Save invoice. The message "Invoice saved" displays the reference and the amount.

Entry aids

Aid How it works
Third-party defaults The first line takes over the default account and VAT code of the third-party record.
VAT code of the account Failing that, the default VAT code of the chosen account is proposed (A21 for most 61 accounts, V21 for 700000...).
Account search Type a number or a word of the label in Account.
To allocate Total incl. VAT entered minus the sum of the net amounts and the VAT of the lines. Red as long as an amount remains, green at zero.
VAT summary Net amount and VAT per VAT code, with the totals.
Period and Document no. The period is derived from the date; the document number is assigned automatically.
Direction of the entries A D or C badge recalls the direction of the allocations according to the journal.

The generated entry

On saving, NovaFisko builds the complete entry. Example for a purchase invoice of 1 000,00 € excluding VAT at 21 %, allocated to account 612000:

Account Debit Credit
612000 Water, gas, electricity 1 000,00
411100 Deductible VAT on purchases 210,00
440000 Suppliers 1 210,00

The direction depends on the journal:

Journal Allocations Third party
Purchases Debit Supplier credited
Sales Credit Customer debited
Purchase credit notes Credit Supplier debited
Sales credit notes Debit Customer credited

For a credit note, enter positive amounts in the credit note journal: the inversion is automatic.

Special VAT cases

Partially deductible VAT. With a code such as A21V (vehicles, 50 % deductible), the deductible part goes to account 411100 and the non-deductible part to account 640200.

Non-deductible VAT. With A21R (restaurant, reception), all the VAT goes to account 640200.

Reverse charge. For an intra-Community acquisition (AICB), an intra-Community service (AICS), work on immovable property under the co-contractor regime (ACO) or an import with deferred payment of VAT (AIMP), the invoice stays net of VAT: the VAT is booked both to the debit of 411100 and to the credit of 451200, and the supplier is credited only with the amount excluding VAT.

Account Debit Credit
604000 Purchases of goods 1 000,00
411100 Deductible VAT on purchases 210,00
451200 VAT payable (reverse charge) 210,00
440000 Suppliers 1 000,00

Sale without Belgian VAT. With VICB, VICS, VEX or VCO, no VAT line is created; only the net amount feeds the corresponding grid of the return.

Note

VAT is computed line by line on the net amount, then grouped by VAT account. If the total of the supplier's document differs by one cent, adjust the net amount of a line or add a rounding line.

Common errors

Message Cause
Choose a journal and a supplier. The header is incomplete.
Add at least one line with an account and an amount. No usable line.
Period locked The date falls within a locked period or a closed fiscal year.
Account not found or not postable The chosen account is a heading account.
Tip

An invoice received as PDF or XML does not need to be entered by hand: drop it in the importer of the Documents tab. See Importer.
