The number of chargebacks that you receive is also a factor in determining your processing limit. You can reduce chargebacks by regularly communicating with your customers. Additionally, you can work with your merchant service provider to reduce your business's risk of chargeback fraud. If your customers are unhappy with your products, they may be more likely to initiate chargebacks. It is a good idea to look for a merchant service provider that has good customer service. Having a good customer service team can help you to reduce chargebacks and keep your chargeback to sales ratio lower.
