Accruals and deferrals
Under Finance → Accruals & deferrals you spread a prepaid expense or deferred income over the months it belongs to.

Some amounts belong to more than one month, such as a year's rent paid in advance. On this page you give them a schedule that spreads them over their months, and each month's share is recognised once in the monthly recognition run, with no new payment.
You'll find it in the sidebar under Finance → Accruals & deferrals. Owners and managers can open it, and so can anyone given a role with the permission to view schedules.
