Credit card error for Bill.com billing
If there is difficulty processing payment for your Bill.com subscription fees based on the credit card on file, an email notification will be sent. To protect your security and privacy, the issuing credit card company cannot provide Bill.com with information regarding why the charge was declined.
To resolve the issue, verify the payment information within the Billing section of your Bill.com account (expiration date, billing address, security code, etc.). A common issue is entering a company address instead of a personal address or vice versa.
Please contact your credit card company to learn more about their policies, including detailed reasons for this particular charge decline. Some issuers put restrictions on using credit cards for electronic or Internet charges.
Update the credit card on the account
Once you've addressed the reason for the declined charge, update your credit card information on the screen that appears after login. A charge will be processed for the outstanding balance when the updated credit card information is saved.
