How to sign a bill of sale online

Sign a bill of sale in three steps

1. 1

   Open the bill of sale in the free signer

   PDF or photographed paper form, both load locally in the browser. Each party can sign on their own device and pass the file along.

2. 2

   Both parties sign and date

   Seller signs first, buyer countersigns (or vice versa, the order doesn't matter legally). Each pass flattens the previous signatures so they can't be altered afterwards.

3. 3

   Both parties keep the final copy

   Download the finished PDF and send it to the other party, matching copies protect both sides in 'as-is' disputes and registration paperwork.

What a good bill of sale includes

Full names and addresses of buyer and seller, description of the item (for vehicles: make, model, year, VIN, odometer), the price and payment method, the date of transfer, and the 'as-is' or warranty language. For vehicles, the bill of sale complements, not replaces, the title transfer and registration steps your motor-vehicle authority requires.

Meeting a stranger from a classifieds site? Signing on your own phones, with the document never uploaded anywhere, is both faster and more private than exchanging paper or emailing the form through third-party tools.

When e-signing isn't enough

Some US states require a notarized bill of sale for vehicle transfers, and title documents themselves often have their own signing rules, check your state's or country's motor-vehicle authority before relying on an e-signed form alone. For ordinary personal property (electronics, furniture, bikes), no special formality applies and the e-signed document is sufficient.

Frequently asked questions

Do both the buyer and seller have to sign?

Best practice is both, and some jurisdictions require both for vehicles. Two signatures make the document useful to each side: the buyer proves ownership transfer, the seller proves the sale date and 'as-is' terms.

Can we sign the same bill of sale on two different phones?

Yes, one party signs and sends the flattened PDF to the other, who opens it in the signer and adds their signature. Each pass bakes the existing signatures into the page, so nothing can be repositioned afterwards.

Does a bill of sale for a car need a notary?

Depends on where you are: a minority of US states require notarization for vehicle bills of sale, and title/registration paperwork has separate rules. Check your motor-vehicle authority; for non-vehicle personal property a notary is generally not required.
