See the recorded product workflowDecisions to make before billing
An accepted-quote review starts with the actual approved proposal version, not whichever file was edited most recently. Record the service scope, price basis, currency and conditions, then match later approved changes separately. A proposed quote or unanswered message does not establish the same billing authority.
Compare like with like. A full project quote and a single stage invoice cover different scopes unless the stage baseline is explicitly defined. Keep tax-inclusive and before-tax amounts distinct, and explain fixed fees, eligible discounts and approved reductions rather than hiding them in one revised number.
The fictional baseline is USD 5,000 plus approved USD 500 additions less USD 200 reductions, giving USD 5,300. A draft of USD 5,400 has USD 100 unexplained excess. A draft of USD 5,300 still needs line-level review because offsetting errors could preserve the total.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Verify the accepted version and conditions
Preserve actual acceptance evidence and the authorized contact. Identify unresolved conditions or later superseding decisions before treating the price as ready.
Match scope and approved changes
Link draft lines to accepted work and change IDs. Hold queried or unapproved work, and use one consistent subtotal basis for the comparison.
Explain variance before release
Compare expected and draft amounts, investigate positive or negative differences and check line identity. Record the final reviewed version and actual release decision.

Avoid this
Forcing the draft to match by inventing a line
A total is a check, not billing authority. Resolve the underlying approved work and price.
Avoid this
Missing an unapproved substitution
An omitted line and unrelated equal-value charge can cancel in the total. Review identity as well as addition.

Questions people usually have before changing the workflow.
Can I compare a stage invoice?
Establish that stage's approved scope and baseline explicitly before comparing; do not use the whole-project price blindly.
Does a client request approve extra price?
Record the actual authorization under the agreed change process. A request alone may still need a priced decision.
Does zero variance mean release automatically?
No. Check scope, conditions, required fields and actual release authority.
