Why stores add SignalDue

Repeat revenue is hiding in your order history

Most stores treat every past customer the same. SignalDue reads the pattern already in your data and tells you who's about to run out — and when.

Perfect-timing win-backs

Reach each customer in the days before they'd naturally reorder — the window when a reminder actually converts instead of annoying.

Predicted vs proven, always separated

Every forecast ships with a confidence score and window — never a fake certainty. You see the signal and the noise, honestly.

FAQ

Questions, answered honestly

How much order history do you need to predict a reorder?
A customer needs at least two past orders of a consumable product before SignalDue forecasts a window. Until then we mark them as "insufficient signal" rather than guessing — the whole point is honest prediction, never fabricated certainty.
Do you write to my store or send emails for me?
No. SignalDue reads your orders read-only and pushes segments to your email/SMS tools. You keep full control of what gets sent — we just make sure it goes out at the right moment to the right people.
How is a "predicted" window different from a "proven" reorder?
Proven means it already happened — measured from a real order. Predicted is our model's forecast, always shown with a confidence score and date range. We never blur the two, so you always know what you're acting on.
Is my customer data safe?
Yes. We access only the order fields required for forecasting, never store payment data, and are built on Shopify's approved data-protection requirements. You can revoke access and purge your data at any time.

Stop guessing who's coming back. Know.
