The gap

Everyone else hands your client an app, or a PDF that forgot the math.

Spreadsheet tools build apps someone has to log into. Proposal tools flatten your formulas into a typed list. Proposolve keeps the numbers live and still sends something a stranger can open, read and sign.

The numbers your client sees are the numbers in your file.

No re-typing prices into a template, no copy of a copy. Upload the spreadsheet or link the Google Sheet, and the proposal reads straight from it. Uploaded formulas keep calculating; a linked sheet shows whatever Google calculates.

Know your spreadsheet works before you pay.

Drop your real pricing model into the compatibility checker and see exactly which formulas run. It reads the file in your browser and never uploads it. No signup, no card, no demo call.

When an import breaks, the AI fixes it with you.

Ask in plain words: this column should multiply B by C, the totals row is missing, this shows #VALUE!. The copilot reads your sheet, proposes the change, and shows you the diff before anything is applied.

Our Solution

Your sheet stays the source. Your client just signs and pays.

  1. Excel, CSV or Google Sheets

    Upload the .xlsx or .csv you already quote from, or paste a Google Sheets link. Every sheet, number and format comes through as a clean, branded table. Your client sees the result, never the file.

    Excel, CSV or Google Sheets
  2. Change the sheet. The proposal follows.

    Link a Google Sheet and it stays the source. Update a rate in Sheets and the proposal your client opens shows the new figure within minutes. No re-export, no re-send, no second version to keep straight.

    Change the sheet. The proposal follows.
  3. An AI Copilot for your numbers

    Ask in plain words: add a VAT row, apply 10% off over $20k, fix this #VALUE!. The copilot proposes the exact cell changes and nothing is applied until you approve.

  4. Signed and paid on the same page

    Your client types their name to sign; we record when, from where, and a fingerprint of exactly what they agreed to. Then they pay by card through your own Stripe account. The money goes straight to you, and Proposolve takes no cut.

    Signed and paid on the same page
  5. Integrates with HubSpot and other CRMs

    Every proposal creates or links its HubSpot deal, with the value, logs when it was sent, opened and signed, and moves the stage when your client decides. Another CRM? A signed webhook reaches Zapier, Make or n8n.

  6. Proposal analytics: who read what

    See who opened your proposal, when, for how long and which sections they read, down to whether they reached your pricing. Follow up while it is still on their screen.

  7. Looks designed, not exported

    Covers, headings, images, video and your tables, in your logo, colours and fonts. It reads properly on a phone, and exports to PDF when someone insists on a file.

Excel, CSV, Google Sheets Proposals

Already have a spreadsheet? Keep it.

Upload any .xlsx or .csv, or link a Google Sheet. Proposolve reads every sheet and every format and turns it into a branded page in seconds. Uploaded formulas stay live and editable; a linked sheet stays in Google and refreshes on its own. Your client sees the result, never the file.

Why Proposolve

The only proposal tool where your spreadsheet keeps working.

Six alternatives, from cheapest to most expensive. Most of them let you type prices into a table. None of them can run your formulas, import your Excel file or update the total when your client changes an input.

A dash means partial or conditional: a PDF has nothing to bill or verify, and PandaDoc and HubSpot have free tiers built around e-signature and CRM rather than proposals.

Capabilities reflect what each vendor documents or markets, checked August 2026. Pricing per user per month at annual billing. We have not bench-tested every competitor, so tell us if something here is out of date and we will correct it.

FAQs

Everything people ask before signing up.

Do real Excel formulas work inside a proposal?

Yes. Proposolve runs a real formula engine inside every proposal, not a static table. SUM, IF, IFS, VLOOKUP, XLOOKUP, SUMIFS, IFERROR and 66 functions in total evaluate live, along with arithmetic, percentages, absolute references like $A$1, ranges and cross-sheet references like Sheet2!A1. Change one cell and every dependent total recalculates. If your model uses something we don't run, link it as a Google Sheet instead. Google does the maths, so any function it supports works.

Can I import an existing Excel file?

Yes. Upload any .xlsx and Proposolve reads every sheet, cell value, formula, and the formatting: bold, colours, borders, merged cells and column widths. Supported formulas come through live and stay editable. Anything unsupported is imported at its last calculated value and flagged, so a number is never silently wrong. The file is then yours to edit inside the proposal; the original upload is discarded.

Can a proposal stay linked to a Google Sheet?

Yes. Share the sheet with Proposolve's read-only address, the way you would share it with a colleague, and paste the link. The proposal shows what Google calculated, in your own number formats, and refreshes within five minutes whenever your client opens it. A linked table is read-only in Proposolve: you keep editing in Sheets, where the numbers live. CSV files work too, uploaded like an .xlsx.

Can my client pay straight from the proposal?

Yes. Connect your own Stripe account once in Settings, set the amount on the proposal, and your client sees a Pay button. Payment runs through Stripe's hosted checkout directly into your account. Proposolve never holds the money and takes no fee on it. The proposal marks itself paid the moment Stripe confirms.

How does signing work?

Your client types their name and accepts. We record who signed, the email they gave, the date and time, IP address and browser, and store a copy of the proposal exactly as it appeared with a SHA-256 fingerprint, so what they agreed to cannot change afterwards. You get a confirmation by email the moment it happens. This is a simple electronic signature, the kind commonly used for commercial agreements; if a particular deal legally requires a qualified signature, use a dedicated signing service for that one.

Does it work with my CRM?

HubSpot is built in. Paste a private-app token, choose which stages mean won and lost, and each proposal creates its deal, or links to one that already exists, with the value. Sent, opened and signed are logged on the deal's timeline, and the stage moves when your client decides. For any other CRM, a signed webhook sends the same events to Zapier, Make or n8n.

How is Proposolve different from Qwilr, PandaDoc or Better Proposals?

Those are design tools that tolerate numbers. If your pricing needs a formula, you build it in Excel and paste a screenshot or a flat table, and it dies there. Proposolve treats the spreadsheet as a first-class citizen: the design layer and the calculation layer are the same document. You get drag-and-drop blocks and a working formula engine in one place, so changing scope means editing a cell, not rebuilding a page.

Can clients change numbers themselves?

Yes. Mark any cell as a client input and it renders as a live field on the proposal your client opens. They type their team size, budget or volume and every dependent figure (totals, ROI, payback) recalculates in front of them. Nothing they type changes your saved proposal; it is their own scenario, not an edit.

What does the client actually see?

A fast, responsive web page at your own link, not a PDF attachment and not a spreadsheet. Formula results are shown rather than formula strings, your brand colours and fonts are applied throughout, and it reads properly on a phone. You can also export the same proposal to PDF when someone insists on a file.

Can I control who opens a proposal?

Yes. Each proposal has its own link and can be protected by an email gate, an access code, or both together for genuinely confidential pricing. Access is checked on the server before any content is sent to the browser, so gated content is never hidden in the page source. Every view is logged with email, time and time-on-page.

How much does Proposolve cost?

Free covers 3 proposals with a small Proposolve badge on the published page. Starter is $29 a month for 20 proposals, 3 seats, no badge, analytics and 50 AI requests. Pro is $59 a month for unlimited proposals, 5 seats ($10 for each extra), a custom domain, unlimited AI and priority support. Signing, payments, Google Sheets and HubSpot are on every plan. No credit card is needed to start.

What does the AI actually do?

It works on the spreadsheet you already have. Ask it to repair a column that imported as text, build a pricing structure from a plain-English description, or explain a formula you inherited. It proposes the exact cell changes and shows you a diff. Nothing is applied until you approve it, and every change is undoable.

Do I have to rebuild a proposal for every client?

No. Save any proposal as a template with merge fields like client_company and client_name, then clone it and fill a short form. A personalised proposal takes under a minute, and cloning copies your formulas and formatting exactly, with no AI cost and no rebuilding.

How long does it take to get started?

Minutes. Sign up, upload a spreadsheet you already use or link a Google Sheet, and send the link. There is no onboarding call and no setup fee. If you know Excel, the grid already works the way you expect, including paste from Excel or Google Sheets with formulas intact.
