Feared loss of custom
If you have an invoice where the whole, or part of, principal amount remains and you suspect that it might never be paid, you can use the built in feature Write down.
This only affects your book keeping and the invoice will not look any different to the customer. If the customer would pay the invoice, it will be handled the same way as any other payment on an invoice and the books will be automatically corrected.
Confirmed customer loss
There is currently no function in Billogram to enter a confirmed customer loss. The only way to get it out of the ledger is to credit the invoice or mark it as Cash Payment.
