The best course of action to prevent chargebacks is to make it ridiculously easy for customers to get in touch with you about refunds and other customer service issues. If the refund process is quicker and easier than issuing a chargeback, your users will be a lot less likely to try the latter. If you do receive chargebacks, I'd recommend keeping extensive records that you can later upload as a PDF file as part of the dispute process. Things like: - IP addresses, logins, usernames and other proof that the customer used the product. - User correspondence acknowledging the purchase. - All invoices sent to the user. - Emails or other documentation displaying cardholder consent for the transaction. While it isn't always easy to win disputes for SaaS business, submitting comprehensive evidence in your dispute response significantly improves your chances.
