For buyers
Upload the seller's bill of sale before you pay.
Bill of Sale Check helps used-car buyers spot missing VINs, odometer gaps, title/lien proof problems, risky payment terms, weak as-is language, and signature issues before money changes hands.
Private beta: public checkout is paused while we finish report language, account saving, and vehicle-history provider integration.
What buyers should check
Fix
Blank VINs, missing names, missing prices, incomplete dates, and unclear signatures should be corrected before payment.
Verify
Compare the VIN, mileage, seller ID, title, lien release, recall status, and vehicle history against the document.
Negotiate or pause
If the seller will not document the basics, use that as leverage or pause the transaction before sending money.
Common private-party paperwork risks
| Risk | Why it matters | Buyer action |
|---|---|---|
| Missing VIN | The document may not identify the exact vehicle. | Add the 17-character VIN and compare it to the title and vehicle. |
| Odometer gap | Mileage may be visible but disclosure language can still be incomplete. | Ask for the odometer disclosure section or state form. |
| Payment not documented | Disputes and scams are easier when payment terms are vague. | Record method, amount, timing, and receipt. |
