In addition to seeing unpaid invoices in the general invoice overview page, you can view all unpaid invoices at the same time.
Marking the invoice paid.
As with the main invoice overview page, this is one of the most useful features of Bright Invoicing. The amounts in a RED box are unpaid, those in a GREEN box are paid.
If you have received payment for an invoice, you can mark it paid by clicking on the RED amount box and turning it green. You can also toggle it back to red to mark it unpaid.
