The documents of everyday commerce

From restocking the shelves to opening a new location: what stores, chains and distributors send for signature most.

Supply agreements

Price, delivery windows and restocking terms agreed with each supplier become a signed contract before the first order.

Franchise agreements

From the franchise disclosure document (Brazil's COF) to the definitive agreement, franchisor and franchisee sign in the same envelope, each through their own link.

Exchange and warranty terms

The customer signs the form at the exchange or product pickup, and the store keeps who authorized it, when and under which conditions.

B2B commercial agreements

Corporate sales, volume pricing tables, reseller partnerships: agreements between companies close without paper going around by courier.

Sales representative agreements

Whoever represents the brand signs commission, territory and targets before going into the field. The termination, when it comes, is documented just the same.

Consignment terms

Consigned goods need a clear owner. The form records what was delivered, the settlement deadline and who answers for the stock.

A B2B order, from proposal to ERP

The path of a corporate sale inside Signater, in the order it happens.

  1. The approved proposal becomes an envelope

    Closed the deal with a corporate customer? The contract goes into an envelope with sequential signing order and validations set per signer.

  2. The buyer signs through WhatsApp

    They receive the link, review the document on their phone and confirm their identity with the code sent on WhatsApp itself. Nothing to install.

  3. Guarantor and store finish in sequence

    As soon as the buyer is done, the guarantor is released; after them, whoever answers for the store signs and the envelope completes with the full certificate of completion.

  4. The webhook notifies your ERP

    The completion event reaches your system as a POST the moment it happens, and the order moves to invoicing without anyone watching an inbox.

How webhooks work is detailed on the feature page.

Identity validated before releasing the order

Factors configured per signer, on the channel the customer already uses. Every recorded validation becomes evidence in the envelope's certificate of completion.

Code by WhatsApp

The confirmation code reaches the signer's WhatsApp, via the Meta Cloud API with pre-approved templates. Simple for the customer, recorded for the store.

PIX with payer data

The signer makes a symbolic payment through PIX, Brazil's instant-payment system, and the arrangement returns the payer's name, tax ID (CPF/CNPJ) and bank: identity attested by the banking system for installment sales.

Selfie with liveness detection

For store credit and higher amounts, the signer takes a selfie with liveness detection at the moment of signing, and the image enters the certificate of completion as evidence.

The nine available factors, from a code by email to the A1 digital certificate, are on the Identity validation page.

Frequently asked questions

Can my customer sign through WhatsApp?

Yes. The invitation arrives as a link by WhatsApp, SMS or email, and the confirmation code can also be sent on WhatsApp, via the Meta Cloud API with pre-approved templates. The customer opens the document on their phone, types the code and signs, without installing an app.

Can I integrate it with my store's ERP?

Yes, with any system via the REST API: your ERP creates the envelope, publishes it and checks its status through HTTP calls. Webhooks complete the cycle by notifying your system when the envelope is published, signed or declined, with automatic retries when delivery fails.

I have more than one store. Do I need an account for each?

No. Users are unlimited, so each store can have its own team inside the same account. To keep documents separate, create a group vault per store: group members see that vault's documents, and whoever is outside has no access.

Can I set the order in which buyer and guarantor sign?

Yes. In sequential order, each signer is released when the previous one finishes: the buyer signs first, then the guarantor and finally whoever answers for the store. If order does not matter, the parallel flow sends the invitation to everyone at once.

Is an electronically signed sales contract legally valid?

Yes. Electronic signature laws such as the U.S. ESIGN Act and the EU's eIDAS regulation recognize electronic signatures; in Brazil, contracts between private parties can be signed electronically under MP 2,200-2/2001. Signater produces an advanced electronic signature based on a digital certificate, in the PAdES standard. In a dispute or collection, the certificate of completion gathers the evidence of who signed, when and with which validations.
