Support for Finnish Reference Numbers

Jun 19, 2025

This update was published over a year ago. Some of the information may be outdated.

We're excited to announce that Sliptree now supports reference numbers for invoices in Finland!

Reference numbers are a crucial part of invoicing in Finland, helping ensure payments are processed accurately and efficiently. With this update, you can now automatically generate and use Finnish reference numbers on your Sliptree invoices.

Reference numbers can be generated based on the invoice or customer number.

To get started, click on the invoice details (number, date) when creating an invoice, then click on Reference number, and choose whether to use invoice-based or customer-based reference numbers.

Save the settings, and then proceed creating the invoice - the reference number will be automatically generated when you save the invoice.

More details can be found in our help docs.
