Three records that should not merge
| Record | Question answered | Boundary |
|---|---|---|
| Invoice | What did the seller or contractor bill, for what period and described scope? | Billing is not proof of payment, receipt, code approval, quality, or owner acceptance. |
| Proof of payment | What amount left which account, to which payee, on what date? | Payment does not automatically prove every item was delivered, accepted, or complete. |
| Owner acceptance | What did the responsible owner inspect and accept, subject to what exceptions? | Owner acceptance is an operating record; it does not replace permits, inspections, warranties, tax records, or professional review. |
The IRS lists invoices, paid bills, receipts, account statements, canceled checks, and other proof of payment among business supporting documents. It also notes that a combination of documents may be needed to substantiate all elements of a purchase or expense. The owner-acceptance layer is this article’s operating synthesis—not an IRS-created legal form.
A seven-field closeout card
- Legal parties, project or purchase, location, and period.
- Invoice number, date, described scope, amount, taxes, credits, and change references.
- Payment date, amount, account, payee, transaction reference, and reconciliation status.
- Received deliverables and objective inspection or test evidence.
- Owner acceptance date, responsible person, exceptions, and reserved issues.
- Separate permit, regulator, warranty, lien, tax, insurance, or professional evidence when applicable.
- Final stop point: do not call the matter closed while a material scope, safety, legal, payment, or acceptance question remains unresolved.
What the tool does not establish
It does not determine contract rights, tax treatment, permit status, workmanship, liability, warranty coverage, lien rights, or whether payment should be made. Those depend on the actual documents, facts, jurisdiction, responsible owner, and qualified review.
