How to find completed work that has not become an invoice
A practical review for contractors and service businesses.

Separate work done from money billed
A busy team can finish the work while an approval, time record or change order is still missing. A completed job does not necessarily mean an invoice is due immediately. The first task is to make those differences visible.
Use three lists
Gather completed work, approved changes and issued invoices for the same period. Include job identifiers, customer names, dates, amounts where available and responsible owners. Use consistent job identifiers before comparing totals; similar names can create false matches.
Create an exception list
Flag completed jobs without a linked invoice, approved changes not reflected in billing, and records that cannot be matched. Treat each as a question. Contract terms, staged billing, disputes and reporting delays can explain apparent gaps.
Give each exception an owner
Finance reviews the amount and billing terms. Operations supplies missing completion evidence. The account owner handles customer approval where needed. Record the reason, next action and review date so the same issue is not rediscovered every week.
Measure resolution, not alert volume
Track how many exceptions were confirmed, how many were explained and how much approved billing was issued. Do not count every flagged amount as recovered cash or additional profit. Collections and accounting treatment need their own validation.
Where Z can fit
A scoped pilot can compare approved exports, summarize exceptions and prepare follow-up tasks. Start with one business unit and a weekly review. A person approves customer contact, invoice changes and any financial conclusion before action is taken.
