Which accounting software is compatible?

The platform works with virtually all accounting software. Thanks to integrations with collection platforms and the digital mailbox, your documents can automatically reach your accountant regardless of which software they use.

How does it work?

There are two ways to send documents to your accountant:

1. Via collection platforms

Clearfacts and BillToBox are collection platforms that act as intermediaries. You send your documents to the platform, and from there they are automatically forwarded to your accountant’s accounting software.

This works with virtually all common accounting packages:

💡 Tip: Ask your accountant which platform they use. They often already have a preference for Clearfacts or BillToBox.

2. Direct integrations

For some accounting packages we offer a direct integration:

💡 SFTP integrations: For Expert/M+ and BOB Software we can set up an automatic SFTP integration. Contact help@numnum.be to configure this.

3. Via the digital mailbox

Many accounting packages (such as Horus, Admisol, and Billit) support a digital mailbox: a special email address linked to your accounting file. UBL files sent to this address are automatically imported into the correct accounting records.

Here’s how it works:

1. Go to Invoices and click Export
2. Choose Export to accountant
3. Check Send documents in separate emails
4. Enter the digital mailbox email address for your file
5. Click Start Export

Each UBL file is now sent separately by email and automatically arrives in your accounting software.

💡 Tip: Ask your accountant for the digital mailbox email address of your file.
