Prosource was a non-optional selection by my realtor to provide a roof inspection. The service was performed quickly, but they were unwilling to receive any payment besides Credit Card, for which they tacked on an additional 4% fee. They gave me an option of mailing in a check, but they were unwilling to certify the work was done for the bank inspector until they had received it and the check had cleared. They knew I was on a timeline, so there were no options besides paying. The fee for processing credit cards is expected, but it is 1.25%-1.5% above what other vendors charge, and with no alternative payment to get around the fee? You can tell that customer service and satisfaction isn't really a priority here.
