Trust seal & verifiable signature
Every quote your client approves gets signed with a SHA-256 hash, their IP, and the exact date. A visible seal confirms it — and confirms the document is ready to be invoiced with CFDI 4.0.
The backup that ends "I never approved that"
Quoting over WhatsApp or a loose PDF leaves no proof your client accepted the terms. Cord signs every approval with an immutable cryptographic hash — name, IP, date, and time — and shows it in a visible seal right inside the quote.
Key benefits:
- Real evidence, not just an "approved" flag: The audit seal is tied to the exact version of the quote your client saw and accepted.
- Ready to invoice: For Mexican businesses, the seal signals the document is prepared to be stamped with CFDI 4.0 with zero retyping.
- Visible everywhere: The same seal shows up on the public link (
/q) and on any quote embedded via Cord Elements on your own site — it isn't exclusive to one channel.
