Why did my Fortnox invoiced total suddenly jump?

The Fortnox help pages give 3 common reasons. The first to rule out: Contract invoices are created for every period up to the one you choose, so picking a later period can create several periods' invoices on one day.

Is it broken, or just quiet?

A number can fall because fewer people came, or because something stopped counting them. Below are the causes the Fortnox help pages give, and how to check each one yourself.

What causes it?

  1. Contract invoices are created for every period up to the one you choose, so picking a later period can create several periods' invoices on one day.

    In the Fortnox help: Ange fram till och med vilken period du vill att kundfakturorna ska skapas. Skapa avtalsfaktura, read 2026-11-12.

  2. Many contracts can be invoiced together in one go, which puts all of those invoices on the same day.

    In the Fortnox help: bockar sedan för de avtal du vill skapa kundfakturor på Skapa avtalsfaktura, read 2026-11-12.

  3. A recurring invoice set to create more than one invoice per run can add several invoices at once.

    In the Fortnox help: Antal fakturor per fakturering styr hur många fakturor som ska skapas vid varje tillfälle. Återkommande fakturering, read 2026-11-12.

How do I check it myself?

  1. Check the invoice dates on contract invoices created around the jump, to see which periods they were meant for.

    In the Fortnox help: kontrollera fakturadatumet Skapa avtalsfaktura, read 2026-11-12.

  2. Look at which periods a recurring invoice is set to cover, to see whether one run took in more than one period.

    In the Fortnox help: I steg två syns även vilka perioder som det kommer att skapas fakturor från. Återkommande fakturering, read 2026-11-12.

How would I know the day it starts?

  • Feder reads the amount you invoiced in Fortnox each day and compares each day with your own history.
  • It tells you when invoicing goes quiet or moves outside its usual range.

Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.

See what Feder reads from Fortnox, which feeds Money. Feder only reads. It never changes anything in Fortnox.

Where do these answers come from?

Every cause and check on this page comes from the Fortnox help pages, quoted above with the date we read them. Last reviewed 2026-11-12. We read them again by 2027-11-12. If one changes, this page changes or comes down.
