Every discovery call with a self-employed prospect hits the same beat: "Would an S-corp actually save me money?" You've fielded that question two hundred times, and your answer has never once been a sentence — it's a spreadsheet. You plug in their profit and a defensible salary, the workbook produces the self-employment tax delta, and the prospect goes quiet in the good way.
The trouble is when that math runs: live, on a call, after the prospect has already found you. The freelancer googling "S corp worth it" at 11pm never reaches your spreadsheet — she reaches a listicle, or a national tax-prep chain's tool that routes her to their call center. Your best sales asset performs for an audience of one.
The fix is letting the spreadsheet take the discovery calls. Love Spreadsheets converts your workbook into a web calculator that runs your exact formulas, trades results for an email address, and files each visitor's numbers into a Leads tab — so every submission is a discovery call that pre-interviewed itself.
You likely keep some version of all three of these. Confirm each has clean input cells, formula-driven outputs, and a fresh empty tab named Leads. Excel or Google Sheets, unchanged.
| Calculator | Visitor enters | Formulas return |
|---|---|---|
| S-corp vs. sole proprietor | Net profit $160,000; reasonable salary $85,000; state: CO | Estimated annual self-employment tax savings ≈ $9,100 |
| Quarterly estimated tax | Projected profit $120,000; last year's total tax $21,400; filing status: single | Four voucher amounts with their due dates |
| Home-office deduction | Office 180 sq ft; home 2,050 sq ft; annual home costs $28,000 | Simplified-method vs. actual-expense deduction, side by side |
Building and running calculators costs nothing at lovespreadsheets.com; the upgrade exists mainly to serve them from your firm's own domain.
Pick the Calculator template, then lay out the experience in plain English:
"Visitors choose one of my three calculators and enter their business numbers. My sheet's formulas generate the estimate. Collect an email before revealing results, and log the email together with everything they entered as a new row in the Leads tab. On the results screen, label the number an estimate and offer a button to book a call so we can verify it."
That verify-it button is the conversion engine — "here's your ballpark, want it confirmed?" is a far easier yes than "contact us." Three more asks worth making:
Use AI Optimize if the description needs sharpening, answer any follow-up the AI raises, and expect a working calculator in roughly twenty minutes. It ships as a hosted URL, or as downloadable HTML you can slot into your firm's existing site.
Link it from your services page, your newsletter footer, and the LinkedIn post you publish before every quarterly deadline. Then watch what arrives. A generic inquiry says "interested in tax services." A Leads-tab row says: sole proprietor, $340,000 profit, no S-corp election, Colorado. One is a maybe; the other is Monday's first callback.
Be plain with visitors about what they're receiving: an educational estimate, not tax advice. Their real answer depends on facts no web form captures — which is exactly why the results screen ends with a booking button instead of a filing instruction.
The logic is your intellectual property, and it never leaves. Widget builders would force you to reconstruct bracket math inside someone else's interface. Here the workbook remains the engine — and remains yours.
Next tax year is a cell edit. When thresholds and rates update, you revise the sheet the same way you always have, and the public calculator inherits the change instantly.
Busy season stops costing you pipeline. February through April you can't take exploratory calls — but the calculator can, quietly queueing qualified prospects in the Leads tab for May.
Am I giving the analysis away for free? You're giving away a number; the engagement is everything after the number. Nobody reads "$9,100 in estimated savings" and then self-executes a payroll setup and an S-corp election — they call whoever showed them the figure.
What about liability for the estimates? You control the framing. Request disclaimer text on the results screen stating that outputs are estimates for discussion, not advice or a filing position, and keep the sheet's assumptions conservative.
Can I gate some calculators and not others? Yes — the email gate is a per-build choice. Some firms show quarterly voucher amounts freely and reserve the gate for the S-corp analysis, where intent runs highest.
The spreadsheet that wins your discovery calls can win them while you sleep. Bring it to lovespreadsheets.com, brief the Calculator template, and let next quarter's prospects run their own numbers — straight into your Leads tab.
