Frequently asked questions
What is a write-off in Flows ERP?
A write-off records a payment against the plan: a customer's payment against a sales contract, or your payment against a purchase contract. Once it's written off, the balance on the contract updates straight away.
How are partial payments handled?
You can write off the amount that was actually received. The rest of the period stays open and keeps its reminder until it's fully paid.
Can one bank transfer settle several invoices?
A single transfer can settle several invoices with a batch write-off. Select the periods, even across different contracts, and settle them all in one step.
How do we write off many payments at once with Excel?
Download the write-off template, fill in the payments, and upload the file. Flows checks every row and tells you if anything needs fixing.
What are deemed receipt and deemed payment for?
They close amounts that won't actually be paid, such as a discount for damaged goods on the customer side or a quality deduction on the supplier side. The amount is closed and the reason is recorded.
Who can perform write-offs?
Only the people you give permission to can write off payments. Every write-off is recorded with the user, the time, and the amount.
