I overpaid a contract worker with a check. can I correct by adjusting future payments
I pay a contract worker by the piece, for documents completed. in his May billing summary to me, he made a math error and overcharged me by one "piece". The check I wrote for May is not matching invoices posted in May. (one piece overpaid) Can I make a correction by backdating his next "piece" submitted in July to May, then telling him not to include it in his July billing summary?
