Set up Reorder Predictions

Happify Reorder Predictions is installed from Shopify and billed by Shopify. When you install it, Shopify asks you to approve these permissions. Each one is used only for the reason shown.

The app keeps customer name and email, and needs Shopify’s protected customer data approval for them. It does not ask Shopify for phone numbers or addresses and does not store them; if another Happify app on your store needs them (Local Delivery Sheet, Invoice & Packing Slip), they are kept for that app and not shown here. SMS and WhatsApp consent is not used today.

1. Install the app and choose a plan. Every plan starts with a 21-day free trial billed by Shopify.
2. Wait for the first import; the “First import still running” banner clears when it finishes.
3. Open Products and check the classifications. Change any with the Override selector.
4. Open Customers, filter by status, and tag customers in Shopify or send them to Klaviyo.

If you see “Only the last 60 days of orders are included”, Shopify has not yet approved access to older orders. Predictions improve once it does.

The reorder window runs from the 25th to the 75th percentile of the product’s repeat gaps, or the customer’s own median gap when they have enough history. Each customer is placed by days since their last purchase of that product.

A product’s window needs at least five repeat gaps across your customers before the app trusts it.

Each product is replenishable, repeatable, seasonal or one-off, with a “Why” column. Your override is saved and used from then on.

• “Tag customers in Shopify” adds tags such as repeatiq:ready, repeatiq:approaching, repeatiq:high_intent or repeatiq:overdue. This is the only change the app makes to customers, apart from the VIP tag.
• Klaviyo: paste a private API key and list ID in Settings. The key is write-only on the page. Send to Klaviyo from Customers adds subscribed customers to that list with their status, product, due date and days since purchase.
• “Set VIP tag” on the Customers list in Shopify admin adds or removes repeatiq:vip.

Every activation includes only customers subscribed to email marketing in Shopify. The confirmation tells you how many were left out.

Ask Sidekick in Shopify admin, for example “Which products are due for reorder?” or “How many customers are ready to reorder?”. The app answers from the same analysis, read-only and product-level.

Add the “RepeatIQ replenishment” app block to a product or account page to show a heading, message and link, such as “Ready for your next order?”. The text is what you type; the block shows the same message to every shopper.

• Advanced: Download CSV of any audience on Customers.
• Pro: Explain on a customer row for a plain-language reason, and History of settings changes with restore.

Prices are in US dollars per month, billed by Shopify. Every plan starts with a 21-day free trial, and you can change or cancel the plan from the app at any time.

Uninstall from Settings › Apps and sales channels in Shopify admin. Uninstalling cancels the subscription and stops syncing straight away.

• Customer tags the app added (repeatiq:approaching, repeatiq:ready, repeatiq:high_intent, repeatiq:overdue, repeatiq:vip) stay on customers.
• Profiles sent to your Klaviyo list stay in Klaviyo; remove them there if needed.
• Remove the “RepeatIQ replenishment” block from your theme if you added it.

Shopify asks us to delete your store’s data 48 hours after uninstall, and we delete it then. The privacy page for this app lists exactly what is stored and what is deleted.
