# Bill Config Endpoints

> Endpoints for updating and retreiving the Bill Configuration for an Organization.

You can use the **Update BillConfig** endpoint to set a global lock date for **all** Bills - any Bill with a service period end date on or before the set date will be locked and cannot be updated.

<Warning>**Ensure all Bills are Approved!** If you try to set a global lock date when there remains Bills in a *Pending* state whose service period end date is on or before the specified lock date, then you'll receive an error.</Warning>
