Where do I find my invoices?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
Your invoices are under Einstellungen (settings) in the Firma & Tarif (company & plan) tab, in the Rechnungen (invoices) card. The invoice for a month comes on the 16th of the following month, and also by email. The free trial lasts 14 days and costs nothing. After that you pay the base price and the ad share only for the days your company could use MargenOptimierer. Locked days therefore cost nothing.
How it works
- Open Einstellungen and then the Firma & Tarif tab.
- Scroll down to the Rechnungen card. Each row is one month.
- In the So ist diese Rechnung entstanden (how this invoice came about) column, read which tier and how many days the invoice charges for each OTTO account.
- In the Dokument (document) column, click Rechnung (invoice). If the invoice is already paid, the link is called Beleg (receipt) and shows invoice and payment together.
Example: The first invoice after the free trial
Say tier 1 costs 60 € a month. Your free trial ends on 10 November 2026, so in November you pay only for the 20 days after it. In the month your free trial ends, tier 1 always applies, and you pay no ad share that month. For 20 of 30 days that's 40 €, and this invoice comes on 16 December 2026.
Endet deine Testphase am 10.11.2026, zahlst du für November nur die 20 Tage danach.
What else matters on your invoice
What your tier depends on
From the second month on, your tier depends on your revenue at OTTO in that month. If you have several OTTO accounts, each has its own tier and its own base price. The tiers are listed in the Dein Tarif (your plan) card and in the price list.
When an ad share is added
MargenOptimierer calculates the ad share for each OTTO account separately. It's added when that OTTO account's ad revenue reaches the free threshold on the days your company could use MargenOptimierer. The entire ad revenue of those days then counts, not just the part above the free threshold.
If a payment fails
The Zustand (state) column then shows „Zahlung gescheitert“ (payment failed). What to do next is covered in How do I add a card or direct debit?
