A common stumbling block for small businesses is AVS (Address Verification System) mismatches during credit or debit card transactions. There mismatches are fairly common and can occur online or in person. They’re an inconvenience to the customer who temporarily loses the funds used for the purchase and they’re an inconvenience to the merchant because they are often blamed for the error.
The problem occurs when a customer mistypes or doesn’t know the billing address attached to the debit or credit card they’re attempting to use. The money to be transferred then gets put on hold while the credit/debit card company confirms the billing address provided. The merchant does not receive the funds unless the AVS is a match. If it’s not the customer’s bank puts a hold on the funds which appears as a charge to the customer, but the merchant never touches the actual money. The bank holds the funds for 24-48 hours and the credit card company asks the merchant to void the transaction, which again the merchant has no record of being successful in the first place. While the funds are being held before being returned to the customer they call and blame the merchant for the hold on the funds. This creates a massive headache for the merchant and appears as poor customer service.
There are two basic options for the merchant to reduce the frequency of these mismatches. The first is to reduce the number of fields required to match for AVS. You can reduce the AVS requirements to just, for example, zip code. This will reduce the number of errors on input by the customer. If there’s a mismatch on just one field then you, as the merchant, can ‘eyeball’ the mismatch and determine if it’s high-risk or not. A high risk order would be a large bulk order or a suspicious shipping address. If there is a cause for concern the merchant can simply e-mail the customer and confirm the wrong address or zip code; 99% of the time the customer will clear up the error immediately.
The second option is to eliminate AVS match requirements totally. This will prevent duplicate transactions and the customer losing access to funds. This requires you the merchant to make risk assessments for each transaction as to fraudulent activity, but it will eliminate the AVS mismatch problem completely.
