Now give clients a way to buy it.

The terms stop moving

The moment your client opens the proposal, Tolavo stores the exact document they are reading and records its SHA-256 fingerprint. From then on the document, the price, the scope, the permissions, the limits and who it is addressed to cannot be edited through Tolavo, and the database itself refuses an ordinary edit to them. Someone in full control of the database server could still alter them; if the stored document no longer matches its fingerprint, Tolavo accepts nothing, records no payment and charges nothing against it. A different deal means a new proposal.

They never need an account

The page they get contains that proposal and the seller details you fill in for your business — trade name, legal form, registration number, address and contact email, and for a bv or nv its registered name and statutory seat — and, once you ask for payment, that request with the payment details you set — and nothing else about your business. The link is a secret Tolavo shows you once and then keeps only as a hash.

Accepting is recorded, not signed

Acceptance records who agreed, when, and the fingerprint of the exact terms they accepted, which they are shown afterwards to keep. Tolavo does not call that a signature, because it is not one, and a record that claims more than it is worth is worth nothing.
