Billing Cycle Checklist
A reliable billing cycle turns invoicing from a scramble into a routine. This checklist sets out the steps to run a complete billing run on time.
What this checklist covers
- Run a billing cycle to a repeatable schedule
- Make sure every billable item is captured
- Issue invoices accurately and on time
- Reconcile the run so nothing is missed
- Smooth out cash flow with a steady rhythm

Before you start
A billing cycle is the regular rhythm on which you raise and send invoices — weekly, fortnightly or monthly. Running it as a defined routine, rather than billing whenever someone remembers, is one of the simplest ways to steady cash flow and stop revenue slipping through the cracks. Before a run, fix the cut-off date so everyone knows what counts in this cycle.
Have your list of billable jobs, timesheets, delivery records and recurring schedules ready. The whole point of a cycle is that the inputs are gathered before you start, not chased halfway through. A steady cycle also shortens the time from doing the work to getting paid.
Gather everything billable
The first step is to make sure nothing billable is left out:
- Completed jobs and deliveries since the last cut-off
- Approved timesheets and logged hours
- Billable expenses and disbursements to on-charge
- Recurring charges due this cycle
- Approved variations and extra work
Unbilled work is invisible revenue — a single forgotten job can wipe out the benefit of the whole run.
Raise and check the invoices
Now turn the captured items into invoices:
- Raise each invoice against its job, PO or contract
- Apply the correct rates, deposits and GST
- Run each through your accuracy check
- Confirm invoice numbers follow the sequence
- Set the due date from your standard terms
- Confirm the right billing contact for each
Batch the checking rather than doing it ad hoc — a consistent pass over the whole run catches errors a one-at-a-time approach misses.
Send and reconcile the run
Finally, get the invoices out and confirm the run is complete:
- Send every invoice in the run on the same day where possible
- Record what was sent, when and to whom
- Reconcile the run total against the work captured
- Confirm no expected invoice is missing
- Diarise due dates and the first reminder for each
Reconciling closes the loop: if the run total does not match the work you logged, you have found a missing invoice before the customer does.
Common mistakes
Billing runs fail in predictable ways. Watch for:
- Unbilled work — jobs that never made it into the run
- Drifting cut-off — no clear date for what counts this cycle
- Late run — slipping the cycle so payment slips with it
- No reconciliation — never checking the run is complete
A fixed schedule and a reconciliation step fix most of these. Our free invoice tools help you keep invoices consistent across a run, and if your cycle is in place but cash is still slow, see how to reduce the time it takes to get paid.
Key takeaways
- Run billing on a fixed schedule with a clear cut-off date.
- Gather every billable item before you start the run.
- Check the whole batch consistently rather than invoice by invoice.
- Reconcile the run total to confirm nothing was missed.
Frequently asked questions
How often should I run a billing cycle?
It depends on your business, but the more regular the better for cash flow. Many SMEs bill weekly or monthly. The key is consistency so customers and your team know the rhythm.
What is a billing cut-off date?
The date that decides what work falls into this cycle. Anything completed by the cut-off is billed now; anything after rolls to the next cycle. A clear cut-off stops arguments about what should have been billed.
Should every invoice in a run go out the same day?
Where possible, yes. Sending the run together makes it easy to reconcile, keeps due dates aligned, and gives you a single point to record what was sent.
