When a customer accepts a quote, Quoterium records evidence of who accepted what, when and from where. How customers accept and sign is covered in Accepting a quote and e-signatures; this article explains the evidence itself.
What is recorded
- Certificate id: a unique reference for the acceptance, starting with SIG-.
- Document hash: a SHA-256 fingerprint of the content the customer agreed to, including the quote number, title, text, items, totals and payment milestones. Any later change to that content would produce a different hash.
- Signed by: the name the customer entered and their email address, marked (email verified) when they confirmed it with a one-time code. If you accepted on the customer's behalf, the certificate says it was recorded by your organisation.
- Signed at: the date and time, including the exact UTC timestamp.
- IP address and Device (browser and operating system).
- Signature: the drawn or typed signature, if one was given.
- Countersigned: when your organisation countersigned, and by whom.
Where to find it
The Signature certificate is printed at the end of the accepted quote's PDF, followed by an Audit trail of the quote's key events. Download the PDF from the quote's actions menu with Download PDF. Your team can also see the full history of a quote under History in the editor.
Making the evidence stronger
Under Settings → Branding & layout you can require the customer to tick the acceptance statement, require a signature, and require them to verify their email with a one-time code before signing. Countersigning accepted quotes adds your own signature to the record.
If an acceptance is undone
If you use Undo acceptance on a quote, the certificate and any countersignature are cleared. A new acceptance creates a new certificate.
Whether an electronic acceptance is legally binding depends on your contract, your customer and the law that applies. Quoterium provides the record; it isn't legal advice. If in doubt, ask a lawyer.
