Can I sue a customer for non payment of items brought in specifcally for them but have repo from customer.

Under the uniform commercial code which Pennsylvania law mostly incorporates, the rejection of goods by a buyer must be within a reasonable time after their delivery. It is ineffective unless the buyer seasonably notifies the seller. The buyer's failure to state in connection with rejection a particular defect which is ascertainable by reasonable inspection precludes him from relying on the unstated defect to justify rejection or to establish a seller's breach.

The short answer is yes. You can begin a court action. Caution: suing and winning are two different things. The question of fact and the strength of your case will be tested against the particulars of the product and whether their rejection of your items was justifiable under the law.
