By mistake, user associated time entries with the wrong project phase and wants to fix the invoice and payment related to this invoice.
BQE CORE gives you an option to reverse payments and invoices. When reversing invoices, CORE cancels your billing decisions and releases the WIP (approved time and expenses) back into the database for later billing. In this case, you can reverse the payment and then reverse the invoice, make the correction to the time entries by moving them to another phase, and then re-process the correct invoice.
