Retail and online shops
Your orders become invoices.
Connect your online shop, import your catalogue in one go and track your orders with suppliers until delivery. Your accountant gets everything without retyping.
I retype every online order as an invoice.
Your online orders become invoices
With the online shop integration, every order becomes an invoice automatically, and your accountant gets it like any other.
The integrations page shows which shops this works with.
My product list is in an Excel file.
Your catalogue imported in one go
Import products with their price, VAT rate and unit from Excel in one go. After that they go onto your quotes and invoices with one click.
I sell sets, but I want one line on the invoice.
A set is one sales line
With bundled products you combine several items into one sales line. Your quote or invoice shows the set, not a row of separate items.
My business customers want a Peppol invoice.
Peppol for every business customer
Since 1 January 2026, you invoice other Belgian businesses via Peppol. That is included in every plan, at no extra cost. Add a customer with their VAT number: name and address come from the official database, and you see straight away whether they receive via Peppol.
What did I order again, and has it arrived?
Orders tracked until delivery
Order from your suppliers with a purchase order in your own branding and track it until the delivery has arrived.
My customer says something was missing from the delivery.
Every delivery on record
With a delivery note you record what was delivered, linked to the order or the invoice. You can also turn a quote or invoice into a delivery note.
Retyping supplier invoices.
Purchase invoices come in automatically
Via Peppol, purchase invoices arrive as structured data, with the supplier, amounts and VAT already filled in. You check them, your accountant gets them automatically.
Customer story
“I had already tried 2 other invoicing programs when I came across NumNum. With NumNum I can do more, and I pay less. It's very useful that you can see whether the customer has opened your invoice.”
