01Define what complete means
A technician marking a job finished does not always mean finance can bill it. Agree the prerequisites for each job type: completed work, accepted variations, required evidence, customer reference and any responsible approval. Record operational completion separately from acceptance for invoicing.
02Build an invoice-ready handoff
Send the accepted job reference, customer account, agreed chargeable items and supporting evidence to finance. Identify the authoritative source for each field. A named finance reviewer should see what is ready, what has already been invoiced and what needs a decision, without recreating a second job list.
03Return incomplete or disputed work
Missing purchase-order details, a disputed variation or a customer refusing acceptance need an owner and reason. Return only the unresolved item to operations, retain the evidence already accepted and prevent duplicate invoice drafts when the corrected record is submitted again.
