Invoices

Every invoice, until it is paid

Issue invoices the way Estonian companies and banks expect them, with a reference number on each. When the money arrives, the bank statement’s line finds its invoice by that number and marks it paid; what is late comes first.

An invoice’s life

From draft to paid

  1. Draft

    Written and kept to change; not yet a document.

  2. Issued

    A number, a reference and a due date. From here it counts.

  3. Sent

    Marked as sent to the customer, with the day.

  4. Paid

    The bank statement’s line found it by its reference.

  • Credit note

    A negative invoice that settles the original, numbered C-n.

  • Copy

    A new draft from an old invoice, for the next month.

Frequently
asked questions

Can’t find your answer? Write to us

  • You issue the invoice in Profflow and it is ready to print or save as a document with the reference number; you mark it sent when you send it. E-invoicing operators are planned connections.

  • When you import the bank statement, each incoming payment is matched to its invoice by the reference number. You can also record a payment by hand; the statement replaces it when it arrives.

  • Not silently. An issued invoice is corrected with a credit note that settles it, or cancelled if nothing has been paid on it — so the books keep the trail.
