What The Signing Record Proves
Plain facts about each signature.
Name
The name your client typed to sign, which must match the name on the request.
Time
When the signature was made.
IP Address And Device
The IP address the signature came from, and the device your client signed on.
Document Fingerprint
A SHA-256 fingerprint of the estimate, so you can tell which version was signed.
How Signing Works
You send, they sign, you keep the record.
Send The Request
Choose the estimate, the signer and how long the request stays open.
They Sign
They read the estimate and type their name. No app, no account.
Signing Rules That Protect You
Three things that keep every signature clear.
- The named signer only: the typed name must match the request
- Your timing: signing doesn’t create an invoice
- Requests expire: send a new one if your client needs more time

What Customers Say
“I built QuickBilling because sending an invoice should feel like sending a link. I want to know when it has been opened, and I want reminders to go out before and after the due date without me writing them by hand.”
“I send an estimate as a link, my client accepts it without needing an account, and I convert it to an invoice in one click.”
“I can see when a client has opened an invoice, and the reminder schedule does the nudging for me. I no longer write those awkward follow-up emails.”

How Does A Client Sign An Estimate?
You send the estimate for signature to a named person. They open the link, type their name to sign, and the result shows in QuickBilling.
Does The Signer Need An Account Or App?
No. The link opens a web page, with no account to create and no app to install.
What Does The Signing Record Show?
The name typed, the time, the IP address, the device and a SHA-256 fingerprint of the estimate. You can download it.
Who Can Sign An Estimate?
Only the person named on the request. The name they type must match.
Can A Signed Estimate Become An Invoice?
Yes. An accepted estimate offers Convert to Invoice, and you choose when to do it.
What Happens When A Request Expires?
It stops working. Send a new request if your client needs more time.
