See the recorded product workflowDecisions to make before billing
An overdue report cannot reveal work that has never reached an invoice. A month-end unbilled-work review starts earlier in the pipeline: delivered tasks, reviewed timesheets, accepted milestones, approved changes and supported expenses. Each needs a billing trigger and a traceable next action.
Do not confuse the pipeline with receivables or accounting revenue. An estimated charge can be unbilled and still lack approval. This review determines operational invoice readiness under the agreement; it does not make a revenue-recognition or tax-period decision.
Use stable work references to connect the register, approval and eventual invoice. The objective is to make each eligible item reach billing once, while keeping blocked items visible. A cutoff date helps organize the run but does not supply authority to charge incomplete or disputed work.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Collect items from the delivery records
Compare the work tracker, reviewed time exports, change approvals and expense evidence with prior invoices. Identify the service period, amount basis and contractual billing trigger for each item.
Classify readiness and assign exceptions
Mark ready, needs review, blocked or held. A ready amount needs its approval evidence; a blocked estimate needs the missing requirement, owner and next review date. Check relevant PO or project cap headroom before submission.
Link the billing decision to a document
Before drafting, check planned invoices and existing schedules for the same work reference. After the item is properly invoiced, save the invoice ID and amount on the register. Carry held items to a named later review, not an unexplained new total.

Avoid this
Adding estimates to the client balance
The unbilled register is not a client statement. Keep proposed amounts separate from issued invoice balances until the proper billing record exists.
Avoid this
Re-entering the same work next month
An item with no invoice reference can look unbilled again after it was charged. Record the actual invoice link and remove it from the ready-to-bill set.

Questions people usually have before changing the workflow.
Can approved work miss the current cutoff?
Yes. Record the reason and agreed next billing action. Do not lose the item simply because it falls outside the current operational run.
How should I handle a missing PO?
Treat it as a specific blocker with an owner. Confirm the client's actual purchasing requirements before sending the charge.
Is every delivered hour billable?
No. Check the agreed categories, acceptance and approval process. Delivery evidence and authority to bill are separate checks.
