We wrote our own system that preauths to get AVS, mandates a match to proceed or automatically voids the auth. You wouldn't believe his many people don't seem to know their own billing address. Customers get frustrated about the strict enforcement but we've only ever had one or two complaints about held funds. We just explain that those pending charges will fall off in 24 hrs, and they accept. Frankly, if the charge risks putting the customer over their limit, then it might not be such a good idea to deal with those customers. The cheapest customers are the most trouble and carry a higher incidence of returns fraud, fraudulent chargebacks, etc.
