Profit & ad-efficiency analysis for e-commerce
Your ad platform grades its own homework. Your ledger doesn’t.
Financial Compass links your store’s business numbers to your ad-platform numbers, day by day, inside a Google Sheet you own — so you can see your true contribution margin and decide exactly how much to spend on ads.
- Business truth
- Contribution margin
- Platform claim
- Reported ROAS
- The gap between them
- Your decision↗
A working system, not another dashboard
Financial Compass is a structured Google Sheets system, set up and operated with the help of an AI assistant. It rolls daily sales and advertising data into weekly and monthly profit views, then puts your actual margins next to what the ad platforms report about themselves.
Everything lives in your own spreadsheet, in your own Google account. No new logins, no black box, no vendor holding your data.
- Connect your sheetYou sign in with Google once and choose the spreadsheet the system works in.
- Numbers flow in dailyOrders and ad spend land in staging tabs; costs and goals are captured once.
- Read the compassDaily, weekly, and monthly P&L — plus the business-versus-platform gap that tells you whether to lean in or pull back.
What Financial Compass accesses — and what it never touches
| Scope | Detail |
|---|---|
| Google Sheets you connect | Reads your business figures and writes calculated results (margins, efficiency metrics) back into the same spreadsheet. This is the app’s only Google permission. |
| Your Google Drive, Gmail, contacts | Never requested. The app cannot see, list, or open anything beyond the spreadsheets you use it with. |
| Your data on our servers | None. Processing happens on your own computer; we run no servers that store your information. |
| Sign-in credentials | Your Google sign-in token is stored only on your own machine, and you can revoke it any time from your Google account settings. |
