Adjusting lump sum payment against invoices

Hello developer.
I am facing hard time against adjusting lump sum payment received from Amazon against the bill that I have generated. So just wanted to know if there is a way to adjust this payment against the bill. Your advice will be really helpful to me.
Thanks and regards

please read the below

You need to explain the situation in more detail. What do you mean by “adjust this payment against the bill?” Are you referring to applying a single payment against multiple sales invoices, reconciling tax amounts, recording fees deducted by Amazon, or something else entirely?

Thank you so much for the help. That really saved my day. It’s exactly what I was looking for. Thanks again.

Thanks Tut
