We worked on a project for a customer and now we received 4 checks that are post marked. The first check was returned for NSF and just Friday we were able to deposit that check which was dated 7/7/2022. The check dated 7/21/2022 the bank is telling us that there aren't enough funds to deposit it. We also have two checks post dated to August 4, 2022 and August 18, 2022. The deadline to file a bond claim is 8/11/2022. Since we did get the funds for the first check should we file anything against our customer or what are our options to get this money sooner?
