Modifying and cancelling subscriptions
A subscription may change over time, for instance the price or quantity of a product. To update you can simply specify the desired changes and set an effective date. We will then automatically make the changes and modify the billing respectively.
When you need to modify or cancel a billed subscription, Proper gives you several options of handling the invoice.
- Credit note entire invoice: Refunds the total amount of the invoice.
- Credit/charge custom amount: Refund only a partial amount of the invoice. Choose between a custom amount or quantity-based credit.
- Pro rata: Refunds a pro-rata amount based on used period. If applicable, an additional charge for the remaining period is added as a new line item on the next invoice. You can select to prorate based on the period start, the effective date of the change, or another specific date.
- No refund: Cancel the subscription without issuing a refund to your customer.
How changes to subscriptions work
Immediate vs scheduled changes
- Immediate changes: Take effect right away and are either prorated or applied to the next billing cycle
- Scheduled changes: Take effect on a specific future date
Effects of changes
Price changes
- Price increase: Customer pays the old price until the effective date, then the new price
- Price decrease: Customer gets the new lower price from the effective date
- Example: Monthly subscription changes from €100 to €120 on March 1st. February bill is €100, March bill is €120
If the change is mid-period, Proper will automatically prorate the change.
Quantity changes
- Quantity increase: Customer gets charged for more units from the effective date
- Quantity decrease: Customer gets charged for fewer units from the effective date
- Example: 5-user subscription changes to 10 users on June 1st. May bill is for 5 users, June bill is for 10 users
