From seller paperwork to a before-payment action plan.
Bill of Sale Check extracts visible bill-of-sale fields, applies deterministic paperwork rules, runs VIN/recall checks when a VIN is visible, adds market context when possible, and returns a buyer-friendly report.
The review flow
1. Upload
Upload a PDF, phone photo, or screenshot of the seller's bill of sale.
2. Extract
The system reads visible fields such as VIN, price, mileage, parties, addresses, and terms.
3. Check
A rules engine checks consistent categories so the same document gets stable issue labels.
4. Verify
When a VIN is visible, NHTSA decode and recall checks add vehicle context.
5. Compare
A directional market scan helps frame whether price and paperwork issues create negotiation leverage.
6. Decide
The report organizes next steps into fix, verify, negotiate, or walk away triggers.
What the report is not
It is not legal advice, attorney review, title/lien verification, DMV/tax/title filing, title insurance, a mechanic inspection, a full vehicle-history report, or a guarantee that every issue will be found. It is a practical paperwork and transaction-risk layer before payment.
How issues are organized
The report is written for a buyer who has to make a decision soon. Instead of treating every missing field as equal, the review separates findings by action. Some issues are simple fixes, such as a missing address or incomplete date. Some require verification, such as a title/lien claim or mileage statement. Some create negotiation leverage, such as undocumented fees or unclear payment terms. A few issues may be serious enough to pause the transaction until the seller produces better proof.
Inputs that improve the review
- A clear photo or PDF of the bill of sale.
- The VIN, year, make, model, mileage, sale price, and state.
- Any title, lien-release, registration, inspection, or emissions paperwork the seller provided.
- The payment method and timing the seller requested.
- Any promises about repairs, warranty, deposits, delivery, or refunds.
Why the review happens before payment
Bill-of-sale problems are easiest to fix while the buyer still has leverage. Once money changes hands, missing title signatures, lien proof, odometer disclosure, or vague payment terms become harder to correct. The review is designed to surface those issues before the buyer commits funds.
