Yup. Get Quickbooks (even of you don't set up accounts or track every cent) to enter customers, do estimates, invoices... You can track "pending," PAID, or final invoices and enter customer payments very easily.
All my monthly invoices get a "pending" stamp on them until I send them out at the end of the month and all regular ones are not marked. They get marked PAID when I enter the check and all is tracked.
