Ask for the promise before you pay.
Build one short message that sends a seller to a clean receipt form for the price, deposit split, delivery range, returns, and cancellation terms. You send it through the channel you already use with the seller.
READY TO SEND
One message. No account handoff.
Preview the seller formOfferChecksum does not send this message, identify either party, process payment, or prove agreement. Only send it to a seller you are already dealing with.
Use the existing written channel
Copy the generated text into the seller conversation you already control. OfferChecksum never sees that conversation.
No demo terms are assumed
The seller form starts blank for every commercial promise that needs judgment.
A public checksum is created
The resulting receipt gets a timestamp, SHA-256 fingerprint, verification link, and badge HTML.
Verification introduces the next merchant
Every public receipt links to the free maker and back to this seller-request route.
Scope: this tool creates a draft request and seller-form link in your browser. It does not submit a receipt. A receipt exists only if the seller reviews the public commercial terms and chooses to seal them.
