View the history of an invoice
On your SumUp profile, select "Invoices" from the left-hand menu.
Open the invoice you want to check up on.
Scroll down and click "History".
From your invoice's history, you can review every change made to the invoice. From its creation to when it was sent and paid, you can even view any connected payments or if it ever became overdue.
You can also use the available search bar and filter settings to check and amend multiple invoice statuses at once.
