The information on a customer for their next billing date is a stamped value which is updated any time a subscription recharges. There are a number of potential reasons the billing date of a customer is in the past:
- If the customer is on hold or suspended, or the customer recently came out of on hold or suspended, then the billing date will only update a full billing period after they have been unpaused.
- If Advanced Taxation or Avalara Direct is enabled, verify that the customer's address is correct. Errors will be cause by an invalid address for customers in your nexus jurisdictions.
