Contracts are usually used to move an account to a different plan on a defined schedule.
- Plan A for 6 months
- Plan B for 12 months
The number of invoices issued depends on the billing frequency of the plans. For example, if Plan A and Plan B both bill monthly, then a total of 18 invoices will be issued under this contract.
When you set up the contract, you also choose what happens at the end of the last contract: stop billing, or continue with the final plan.
If you just want to limit the length of a subscription (for example, have it automatically cancel after 9 months), then you could consider one of these options:
- Create a fixed-term plan with a length of X months. Every subscription for this plan will cancel after a set amount of time.
- Create a contract with only one contract period, for the amount of time you want. When you create the contract, you should set it to stop invoicing when it reaches the end date.
