To record a payment select an invoice from the list and click on the Payments tab.
An invoice can be paid in full or partially.
If you have a partially paid invoice, click on Record Payment and enter the amount that has been paid.
Productive will automatically calculate how much remains to be paid.
Add as many payments as you need by clicking on the "+New" button and selecting Payment.
Writeoff remaining debt
If there is a problem with a client and you need to write off a certain amount, click the "+NEW" button and select Writeoff.
Once you have recorded all the payments (and hopefully zero write-offs), the status of your invoice will change from Unpaid to Paid.
Edit and Delete a Payment
To edit or delete a recorded payment click on the payment you want to change and select one of the options.
