From Estimate To Invoice In Three Steps
Send it, they accept, you convert.
Send It
To the person who will approve it, by name.
They Accept
By typing their name. No app or account.
Convert It
One click, when you decide.
Send The Estimate, Get A Yes Back
Your client opens it, types their name and accepts. The accepted estimate is then ready to convert.
- Accept or decline from the link
- You get an email when they respond
- Every line item carries over to the invoice
What To Know Before Sending
Rules that keep approvals clean.
A Named Approver
You enter their name when you send, and only that person can accept.
You Control Invoicing
Acceptance never creates an invoice by itself. You choose when to convert.
No Account Needed
They accept on a web page, with nothing to install.
Proof Of Acceptance
Every acceptance creates a signing record. See e-signatures for what it contains.
Built For Quote-First Work
Where online approval speeds up the yes.
Bathroom Refit Quote
Send the itemized quote; the homeowner accepts on their phone that evening.
Design Project
The client accepts the scope, then you convert it into the deposit invoice.
Commercial Job
The named approver accepts, so you know exactly who said yes.
Revised Estimate
Send a revised estimate if the scope changes, then convert the accepted one.

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.”
