Avoid double billing when changing plans
A
Agustín
When the plan associated with a subscription changes during the billing period, the customer may be billed twice for the same day. For example:
- On 1 November, plan A is assigned to the customer;
- On 20 November, customer upgrades to plan B;
- Result: plan A is billed for the period 1 November to 20 November, and plan B is billed for the period 20 November to 30 November.
In this scenario, the customer is billed twice for 20 November. We want to avoid this situation.
