Verified Bill of Sale · Used & Secondhand Goods

A BILL OF SALE FOR ANYTHING YOU SELL SECONDHAND.

Q: Is a SENT. bill of sale a legal document?

It is cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It is independent, tamper-evident evidence you can show a buyer, a marketplace, or a payment processor.

Before money changes hands on furniture, a bike, a tool, a collectible — anything — seal the description, condition, price, parties and photos into a cryptographic, tamper-evident record. When a buyer later claims "item not as described" or accuses you of a scam, the proof of exactly what was sold already exists — dated and unalterable. The proof exists before the dispute can.

// The dispute this prevents

"IT WASN'T WHAT YOU DESCRIBED."

Every private sale — Facebook Marketplace, Craigslist, OfferUp, a local pickup — rests on a description and a handshake. When buyer's remorse sets in, the story changes: the item was damaged, it was missing parts, it "didn't work," it wasn't what the listing said. With payment apps now offering buyer protection, an "item not as described" claim can pull the money straight back out of your account, and the seller is left with nothing but screenshots either side could have edited.

Without a sealed record

A listing that can be deleted. Chat messages that can be edited or selectively screenshotted. Photos no one can prove were taken before the sale. When the claim comes, there's no neutral record of what was actually agreed.

With a SENT. bill of sale

A dated, cryptographically sealed record of the item, condition, price, both parties and the actual photos — created before money moved and impossible to backdate, with the buyer's own acknowledgment sealed in. The terms can't be rewritten after the fact.

// How it works — three steps

Describe the item

Enter the buyer and seller, the price, and a clear description and condition. The universal form fits any item — furniture, tools, bikes, collectibles, instruments, appliances.

Add the evidence

Attach photos of the item and any receipts or manuals, and declare any known flaws up front. Every file is hashed in your browser before it uploads, so the images are sealed exactly as they are.

Seal & send

The record is sealed with a timestamp and signature, and the buyer gets a link to acknowledge the terms. Their acknowledgment is sealed into the same record. Anyone can verify it — no account required.

// What gets sealed

EVERYTHING THAT SETTLES THE ARGUMENT.

✓Item & description — exactly what's being sold.
✓Condition & disclosures — flaws and "sold as-is" declared up front.
✓Price & parties — who sold what to whom, for how much.
✓Condition photos — hashed before upload, sealed as-is.
✓Provenance — where it came from and that it's clear to sell.
✓Buyer's acknowledgment — sealed with timestamp and IP.

// Questions

PRIVATE SELLERS ASK

Is this a legal document?

It's cryptographic proof of a transaction and its agreed terms — what was sold, by whom, to whom, when, and in what condition. It is not a legal title transfer and not legal advice. It's independent, tamper-evident evidence you can show a buyer, a marketplace, or a payment processor.

What kinds of items can I use it for?

Any used or secondhand item — furniture, tools, bikes, collectibles, instruments, appliances, equipment. There are dedicated flows for sneakers, jewelry and electronics if you need category-specific fields.

How does it help with an "item not as described" claim?

The record is sealed before money changes hands and timestamped cryptographically, so it can't be backdated. You have a dated record of the description, condition and photos you both agreed to at the point of sale.

What does it cost?

Pay per transfer, or create unlimited transfers on a Solo plan — see pricing. The same cryptographic guarantee applies either way.
