Mailbox intake and multi-page PDFs

Give each company a mailbox, let suppliers keep emailing it, and watch a 13-page PDF of separate invoices arrive as thirteen documents.

The fastest invoice to process is one nobody has to upload. Give each company its own mailbox in Invoreg, and invoices arrive within a minute of the supplier sending them. A single PDF holding several invoices is split into separate documents, and phone photos and scans are read too.

Set up a mailbox, step by step

  1. Open the organisation's settings. Go to Settings and open Email mailboxes.
  2. Add a mailbox. Connect the address suppliers already send to, or create a new one and set up a forward from the old address.
  3. Keep one mailbox per company. Every invoice then lands in the right client organisation without anyone sorting it.
  4. Send a test. Email an invoice to the address. Within about a minute it appears in Buying with the status New: unregistered, waiting for a check.
  5. Tell suppliers nothing, if you connected the existing address. If you created a new one, add it to purchase orders and your email signature over time.

Multi-page PDFs

Some suppliers send a month of invoices as one PDF. Invoreg splits it: a 13-page PDF holding thirteen invoices becomes thirteen separate documents, each read on its own with its own number, date, lines and total.

That matters for two reasons. Each invoice can be checked, approved and registered on its own, and duplicate checks work per invoice rather than per file.

Phone photos and scans

The same mailbox accepts photos and scans, not only PDFs:

  • Formats: JPG, PNG and HEIC photos as well as PDFs.
  • Poor captures: low-quality phone photos and even upside-down receipts are straightened and read.
  • Doubts are flagged: anything the AI isn't sure about is marked on the field for the person checking it.

What happens next

Nothing is posted automatically. Every document waits until someone checks it and clicks Register, as in reading and registering your first invoice, and after any purchase approvals you've switched on.

Common questions

Can several people forward to the same mailbox? Yes. Anyone can forward invoices to the organisation's address: suppliers, the client's staff or your own team.

What about invoices that arrive as attachments to reminders? They come in like any other email attachment. If it's the same invoice you already have, it's flagged as a duplicate.

Does the mailbox also take bank statements? Bank statements are uploaded for bank reconciliation, where each payment is matched to the invoices it settles.
