Readiness score
Checks common document fields and payment or trade details. Not tax, legal, or customs advice.
Use the invoice checker as a final pass before you email a client or upload a PDF to a portal. It reviews common invoice fields, payment instructions, total consistency, due dates, and wording that may slow down client approval.
A high score means common fields look complete. The checker does not authenticate the sender or document, and it does not mean the invoice is legally or tax compliant in every country or industry.
Missing invoice numbers, unclear due dates, blank client details, incomplete payment instructions, inconsistent totals, and vague line items may require clarification. Review them before sending while the project details are still available.
Templates help with structure, and the checker helps review the filled-out document. For B2B clients, pay extra attention to PO numbers, billing entity names, tax IDs when relevant, and the email address or portal used for submission.
Use the checker as a structured review of the information you entered. It helps surface ordinary omissions and inconsistent totals; it does not authenticate a document, identify fraud, verify a supplier, or decide tax and legal requirements.
| Review area | What to check | Why it matters |
|---|---|---|
| Document identity | Invoice number, issue date, and due date | The client needs one unambiguous document and payment deadline. |
| Seller and buyer | Business name, client name, and billing entity | The invoice needs to match the entity the client asked you to bill. |
| Charges | Specific line items, quantities, rates, and total | Clear descriptions make the amount easier to approve and reconcile. |
| Payment | Terms, method, instructions, and payment reference | A complete invoice should tell the client how and when to pay. |
| Client workflow | PO number, project code, or AP contact when required | Client-specific references help the buyer route and match the invoice. |
Before
“Services — $2,400” with no work period, due date, payment instructions, billing entity, or PO reference gives the client little information to approve or route.
After
“Website implementation milestone — July 1–15 — $2,400,” paired with invoice INV-2026-0042, a specific due date, Net 15 terms, bank reference, and the client’s PO number is easier to reconcile.
If you already created a draft, the checker can load it from local browser storage. Each issue links back to the relevant generator field, and saved corrections remain in the same browser. Run the check again after changing totals, dates, payment instructions, or client references.
It flags missing invoice numbers, dates, client details, line items, calculation issues, and other common problems that may delay payment.
No. It reviews common fields only and is not tax, legal, or accounting advice.
The checker runs in your browser on the data you enter. Your invoice content is not uploaded for checking.
No. It reviews the fields you enter but does not authenticate the sender, bank account, supplier, tax ID, or underlying transaction.
