How it works

Paste or upload

Copy your transaction history from a spreadsheet or POS export. Three columns: customer, date, amount.

The arithmetic runs

Every customer gets scored on recency, frequency, and spend — all in your browser, nothing sent to a server.

See who is lapsing

Results sorted by urgency. Lapsing customers first, then at-risk, then steady. The math that produced each label is shown alongside it.

What it does — and what it does not

Shows the math

Every label includes the arithmetic that produced it

No black-box score, no predicted churn probability. You see days since last visit, visit count, average interval, total spend — and the threshold that placed this customer in lapsing or steady.

Works from what you already have

Your transaction history is all it needs

No CRM integration, no API setup, no monthly subscription. Paste from a CSV export or upload a file. The analysis finishes in your browser in milliseconds.

Try it with your own data

No signup, no download. Open the tool, paste your transactions, and see who is lapsing in under a minute.
