On the eConnect platform you can configure automatic invoice numbering per organisation. The system then automatically assigns a sequential number to each new invoice you create. With a prefix and suffix you make the numbering recognisable for your administration.

When you activate automatic numbering for an organisation, the platform automatically fills in the invoice number field when you create a new invoice. The number consists of three parts:

1. Prefix: a fixed prefix, for example your Chamber of Commerce number or a company abbreviation
2. Sequential number: the system counts up automatically from the configured starting number
3. Suffix: an optional suffix, for example the year

Example: with prefix EC-, starting number 1001 and suffix -2026, your invoices are numbered as EC-1001-2026, EC-1002-2026, and so on.

The invoice number is automatically filled in as soon as you create a new invoice via the platform. If you want to adjust the number manually, you can overwrite the field before sending the invoice.

Note: automatic numbering only applies to invoices created manually via the platform. Invoices that arrive via the API or Email Receiver use their own numbering.

• Use your Chamber of Commerce number as prefix when sending invoices to government bodies; some recipients require this
• Start with a starting number that connects to your existing administration, so there are no gaps in the sequence
• Keep the prefix short and recognisable, so the invoice number does not become unnecessarily long
