When I accidentally sent a payment to the wrong company due to an error on the coding which wasn’t spotted before the payment run was released. Not long after this I was informed that July client hadn’t been paid for their invoice. I reconciled the weekly run again and notice the company code was inputted incorrectly. I then wrote to the vendors who received the goods in error and explained the situation of which they were compliant and sent the money back to us I then made a same day payment to the original vendor and paid the invoice correctly followed with an apology Last step was to reconcile both the payment run and statements on both vendors I learned to never overlook the importance of double checking the codes and the numbers on invoice match up. I have not made such a big error since
