See the accounts you already lost quietly.
Export your order history, drop it in, and see which customers drifted away — the date we would have caught each one, and how many days of warning that would have given you.
Free, no account, no limit. Anonymise the customer column if you like — codes work fine, and they come back exactly as you sent them.
Drop a CSV of your order history
It needs three columns: a customer identifier, an order date, and an order total. The identifier can be a code — you never have to send us a customer name.
Your file never leaves your browser. Nothing is uploaded, stored, or sent anywhere.
What it looks at
Only how often each account orders and when they stopped. It knows nothing about what is sitting in a customer's stockroom — we cannot see that, and neither can anyone selling you software that claims otherwise.
How it decides
Each account is measured against its own rhythm, not an industry average. An account that orders weekly and an account that orders quarterly are judged on entirely different clocks.
Why it runs here
The whole calculation happens in your browser. Your file is never uploaded, so there is nothing for us to store, leak, or hand to anyone.
