Sales & Invoicing

This is the module everyone turns on, because it carries the only legal obligation of the set: since 1 January 2026, an invoice between VAT-registered companies in Belgium must travel in a structured format. It is included in every plan, with no per-document surcharge.

But compliance is only the door. This module holds the whole chain: what was offered, what was ordered, what was invoiced, what is still owed.

The quote

A quote is a priced proposal, valid until a date. It carries its lines, its per-line discounts and its terms.

• It is revised without being rewritten. A change after issue opens a new version; the previous one stays readable, with its date. You always know what the customer actually received.
• It can be accepted in part. The customer takes three lines out of five? The order is created on those three, and the rest does not vanish into an email thread.

The order, the pivot everyone forgets

Between the quote and the invoice sits what is committed . That is the order, and it is what stops you invoicing the same thing twice.

Each line carries its ordered, delivered and invoiced quantities. An order is settled when every line is invoiced, delivered or cancelled — not when somebody decided it was.

The invoice

A legal document, therefore immutable . Once issued, its content is frozen and its number belongs to an unbroken sequence.

• PEPPOL sending and receiving in UBL 2.1, no per-document surcharge.
• Belgian structured communication ( +++…+++ ) and a SEPA payment QR code : your customer pays without retyping an IBAN.
• Partial payments tracked line by line, and an outstanding amount that is a calculation rather than an estimate.
• Credit notes attached to their invoice, whose total can never exceed the original.
• Recurring invoices for what comes back every month, in the same sequence as the rest.

The receivables side

• Aged balance : what is not yet due, and what is dragging at 30, 60, 90 days and beyond.
• Dunning in configurable tiers. An invoice never receives the same tier twice, which avoids the reminder sent three times to a good customer.
• Billing accounts kept separate from the party directory: the billing address, the payment terms and the schedule belong to the customer role, not to the company identity.

The catalogue

Products and services, families, variants, UN/ECE units, VAT rates and coefficient tags. A product is never deleted — it is retired, and stays readable on documents already issued.
