Payment of a invoice in advantage


I recieved a invoice on this month.
But the month before this month I pay a part of this invoice already.

How can I take care that everything will be allright and the payment is in the system of this invoice.

All explained here Record supplier deposits and advances with example of how to enter the necessary transactions

oke, so manager can handle payments before the payment date. Happy to see that

You should take care that the earlier payment was not specified to apply only to the earlier invoice or you will end up with that invoice being overpaid and the current one underpaid. See this Guide for an explanation: Manager Cloud.
