Google Sheets Add-on

Know who's staying, what's growing, and why.

Find the drop-off point, explain what moved revenue, and see exactly which customers are behind any number -
without leaving Google Sheets.

For SaaS, subscription, membership, and recurring revenue businesses.

Four steps. No context switching.

Everything happens inside Google Sheets. No exports, no new tabs, no other tools.

1

Open the sidebar

Launch from the Extensions menu. Your columns are detected automatically.

2

Map your columns

Customer name, date, and amount. Auto-mapped in most cases - adjust if needed.

3

Pick a report

Retention cohort, revenue waterfall, or data health scan. Core SaaS metrics, one click to generate.

4

Explore & share

Results land in a new tab. Drill into any number, chart it, share it. It's your spreadsheet.

Retention

Spot when customers drop off.

Pick a date range, run a cohort analysis - the kind that takes hours in a spreadsheet, done in seconds inside Google Sheets. Each row is a sign-up month, each column shows who stayed. The heatmap makes the drop-off obvious.

March sign-ups are dropping faster - 26% gone by Month 1 vs. 18-22% for other months.
"Customers who signed up in March are leaving twice as fast as every other month."
That's the kind of answer you get in seconds.
Revenue

See exactly why revenue went up - or down.

Every month broken into new, expansion, contraction, churn, and reactivation revenue. See your churn rate, what's driving it, and how much it's costing you.

Common questions.

Install Jetti Sheets from the Google Workspace Marketplace, open the sidebar, map your customer, date, and amount columns, and click Generate. You'll have a retention cohort with a heatmap in seconds - no formulas, no pivot tables, no exporting.

Three columns: customer name, transaction date, and amount. If your data is in Google Sheets, you're ready. Jetti Sheets auto-detects your columns so you can usually generate a report without any manual mapping.

No. Your data is processed in memory, never written to a database. A temporary cache speeds up drill-downs and reruns, but it auto-expires and you can delete it anytime. Once it's gone, it's gone.

A retention cohort groups customers by sign-up month and tracks how many come back over time - it shows your retention rate and where drop-off happens. A revenue waterfall breaks each month into new, expansion, contraction, churn, and reactivation revenue - it shows why MRR went up or down. Jetti Sheets generates both.

Yes. Jetti Sheets works with any spreadsheet that has recurring transaction data - Stripe exports, billing CSVs, POS data, membership records. If it's in Google Sheets, Jetti Sheets can analyze it.

Every report you generate during the trial stays in your spreadsheet as a normal tab - it's yours to keep. After 7 days, you just lose access to generate new reports until you subscribe.
