Price the proposal before
you write the proposal.
Proposal Estimator lives in the Google Docs sidebar. Set the scope, attach a client, total the line items, and insert a finished proposal without ever opening a spreadsheet.
Free 7-day trial · No credit card required · Works inside any Google Doc
Built for the sidebar, not a second app.
No new login, no separate dashboard. Proposal Estimator opens next to the document you're already writing.
Scope, in one card
Title, notes, and scope summary live in one setup card, with an active-scope indicator so you always know which proposal is live.
Client records
Attach an existing client or create one on the spot. No re-typing a company name for the fifth proposal in a row.
Reusable templates
Save a proposal structure once and start every future estimate from it instead of a blank sidebar.
CSV import & export
Bring in pricing from a spreadsheet you already maintain, or export an estimate to share with finance.
Local browser storage
Drafts save to your browser as you type. Nothing sits on a third-party server until you choose to export it.
One-click insert
When the numbers are right, insert the formatted proposal directly into the open document. No copy-paste.
The same sidebar, right on this page.

Proposal Estimator, in plain answers.
What does Proposal Estimator do?
It's a Google Workspace add-on that opens in the Docs sidebar. You fill in a proposal title, scope notes, and client, then insert a formatted proposal directly into the open document.
Where is my data stored?
Drafts, clients, and templates save to your browser's local storage by default. Nothing is sent to a server unless you explicitly export or import a CSV file.
Can I reuse my own templates?
Yes. Save any proposal structure as a template from the Templates tab, then start future proposals from it instead of a blank scope.
Does it work with any Google Doc?
Yes. Open the add-on from the sidebar of any Google Doc you have edit access to, and insert the proposal at your cursor.
Can I import pricing from a spreadsheet?
Yes, on Pro and Business plans. Import a CSV of line items and pricing, or export a finished estimate to share outside the document.
How does billing work?
Plans are flat monthly fees, not per-seat charges on Business. Every plan starts with a free 7-day trial and no credit card is required to begin.
