How does a statute of limitations work?
Statutes of limitations are very simple. You have a specified amount of time from the date of the infraction to file a suit. If you're outside that window, even by a day, it's too bad, and you're just completely out of luck.
For example, if a customer owed you for unpaid inventory and the statute of limitations in your state was three years, you could file in civil court to collect that money between the moment the debt was considered overdue and three years from that date. So if your contract specified that collections would start at 90 days past due, and they received their goods on March 1, 2023, and failed to pay by May 30, 2023, you'd have until May 30, 2026, to file your grievance. If you filed on May 31, 2026, you'd be out of luck.
