Out-of-Stock Substitute Suggestion
A done-for-you e-commerce and retail automation built for the Conversion Rate Manager, connecting Zapier and Make.com so the work below happens on its own.
What this automation does, step by step
When a customer tries to purchase an item that's sold out, instead of hitting a dead "out of stock" page, this automation automatically surfaces a similar in-stock alternative pulled from the same category using Rebuy or Nosto's product-matching logic, factoring in price range, style, and past purchase behavior when the shopper has an account.
The substitute appears directly on the product page and is also included if the customer had already requested a back-in-stock notification, giving them an immediate option instead of a wait with no clear end date.
Zapier or Make.com keeps the substitute mapping updated as inventory shifts, so a suggested alternative is never itself sold out.
Offering a real alternative in the moment recovers a meaningful share of sales that would otherwise be lost entirely to a dead end, turning what used to be an abandoned session into a completed order.
- Shopify or WooCommerce
- Rebuy or Nosto (product matching)
- Zapier or Make.com
- Klaviyo (back-in-stock fallback)
Using different software? We build around what you already have, so you never have to switch tools to automate.
The manual way vs. the automated way
Without automation
Left unautomated, a conversion rate manager spends hours on the parts of this job that don't require judgment: copying data, sending reminders, and tracking status by hand. It rarely feels urgent in the moment, but it adds up fast.
With this automation
- Status updates triggered by real milestones in your systems
- Support requests routed to the right owner with full context
- Escalations when a response deadline is about to slip
- Fewer inbound status calls for your front desk
