Release 27/9/2026 (6.17)

In this release, we are introducing a brand-new flow for the quarterly VAT closing, allowing businesses and accountants to collaborate even more smoothly. We are also expanding invoicing with full support for billing periods, making it possible to officially reject Peppol invoices, and introducing handy draft previews (PDF) for invoices in preparation.

• Simple quarterly closing
  No more uncertainty about whether your accountant can start preparing the VAT return. Once you have processed all purchase and sales documents from the past quarter in OkiOki, you can now let them know with one click using the new "Ready for closing" button. Your accountant immediately sees in their portal that your file is complete, ensuring a smooth and timely VAT closing without back-and-forth emails.

• Support for billing periods
  For recurring services, subscriptions or projects, it is often important to indicate which period an invoice relates to. From now on, when preparing an invoice, you can easily enter a billing period (start and end date). OkiOki ensures that this period is automatically included correctly in the digital e-invoicing standards (both in Peppol BIS 3.0 and UBL.BE). This means your customer and their accounting department immediately have the right context.

• Reject Peppol invoices with one click (IRM)
  Have you received an invoice via Peppol that is not intended for you or is incorrect in terms of content? From now on, you can officially reject a received Peppol invoice directly from the home screen or the document overview. OkiOki will then send a standardised Invoice Response Message (IRM) back to the supplier via the Peppol network. This ensures that communication concerning disputes takes place entirely according to the official e-invoicing standards.

• Handy draft PDF preview
  Would you like to have an invoice reviewed or checked internally before sending it definitively? You can now download a printable PDF example of your draft invoice. This example contains a clear "DRAFT" watermark and only receives its definitive invoice number once you actually finalise the invoice.

• Card view for the active client overview
  To make the overview of your files even clearer, we are introducing a new card view in the accountant portal. With a handy switch, you can effortlessly switch between the familiar list and the visual card view.

• Bulk switch to self-paying clients
  For accountants with mixed plans, management is now much more efficient: you can now collectively switch active clients to self-paying in one action (or vice versa).

• Modernised Exact Online CODA integration
  The CODA export to Exact Online now uses the latest API integrations. This increases reliability and eliminates the need to select digital mailboxes manually.

• Smooth navigation in VAT selection: When entering invoices, the Tab key now reliably takes you directly to the next field after selecting a VAT rate.

• Improved Excel import of contacts: An error no longer occurs when importing private contacts (without a VAT number) or French VAT numbers via Excel.

• Smooth document conversion: A validation error when directly creating a credit note or quotation based on an existing invoice has been resolved.
