Billing cycle
The regular period, such as monthly, at which a business invoices its customers for recurring or accumulated charges.
In short
- It sets when invoices go out, and therefore when payment clocks start.
- Longer cycles delay cash; shorter ones mean more invoices to manage.
- Many businesses spread customers across the month so invoicing and collections are not all on one day.
A billing cycle is the interval between invoices for a customer. A software company might bill monthly on the date each customer signed up, a utility every two months, a law firm at the end of each month for hours worked, and a subscription box every four weeks.
Why it matters for cash
Payment terms start from the invoice date. A service delivered on the 2nd of the month but billed on the 31st, on net 30 terms, is paid around 60 days after the work began. Moving to more frequent billing, or billing at the start of a period rather than the end, brings cash in sooner without changing the terms at all.
Choosing a cycle
- Anniversary billing: each customer is billed on the date they started, which spreads invoices across the month.
- Calendar billing: everyone is billed on the same date, which is simpler but creates a monthly spike in work and in customer questions.
- Usage billing: charges accumulate during the cycle and are billed at the end, common for metered services.
- Milestone billing: invoices follow project stages rather than dates.
Revenue and billing are not the same
A customer billed annually in advance has paid for twelve months, but revenue is recognized month by month as the service is delivered. The unearned part sits as deferred revenue until then.
Worked example
Moving invoices earlier
A cleaning company bills each client at the end of the month on net 30. Work done on the 1st is paid around the 30th of the next month. It switches to billing in advance on the 1st for the coming month's scheduled visits. Terms stay net 30, but cash arrives about a month earlier, freeing up nearly one month of revenue in working capital.
