Shopify Inbox & Backorders: How to Get Your 'Zero Stock' Products Recommended

Hey there, fellow store owners!

We’ve all been there: you’ve got fantastic products, some of them are so popular they’re often on backorder, and you want your customers to discover them. You’re using Shopify Inbox, maybe even its snazzy new AI agent, to help with customer service and product recommendations. But then you hit a wall. What happens when your agent completely ignores those hot backorder items? It’s frustrating, right? You’re leaving sales on the table!

This exact challenge sparked a really insightful discussion recently in the Shopify Community forums, and I wanted to share the key takeaways. It’s a classic example of how a single setting can have unintended ripple effects across your store, especially with newer AI tools.

The Core Problem: When "Out of Stock" Isn't "Unavailable"

The original post, from a wine store owner named robinthebest, perfectly articulated the issue: their Shopify Inbox agent wasn't surfacing backorder wines, even though customers could still purchase them. This leads to a broken customer experience and lost sales. They wanted a way to tell the agent, "Hey, these are orderable!"

The heart of the problem, as Icey.Lane pointed out, is that Shopify often collapses two very different states into one: zero on hand and not orderable. For many businesses, especially those dealing with pre-orders, custom items, or popular limited runs, these are definitely not the same. A backorder business relies on the ability to sell items that aren't physically in the warehouse right now.

The go-to solution for making backorder items available on your storefront is often the "Continue selling when out of stock" setting on your product variants. And indeed, Ecom_swift_LLC suggested this as a workaround to get the Inbox agent to recognize these items. The logic is sound: if Shopify treats it as "available/orderable," the agent should, too.

The "Continue Selling" Workaround: Proceed with Caution!

So, the first, most straightforward workaround discussed is to simply enable "Continue selling when out of stock" for your backorder variants. Here’s how you’d typically do it:

1. Go to your Shopify admin.
2. Navigate to Products.
3. Select the product with the variant you want to enable for backorder.
4. Scroll down to the Inventory section for that variant.
5. Check the box for "Continue selling when out of stock."

But here’s the crucial caveat, highlighted brilliantly by Luca_Bartoccini (who builds a back-in-stock app, so they know this corner well!): This flag doesn't only talk to Inbox. It signals to your entire Shopify store that the item is available. This means:

• Your Product Detail Page (PDP) might stop showing "Sold Out."
• Any "Notify Me" or "Back in Stock" apps you’re using will likely stop firing, because from Shopify's perspective, the item is never truly "unavailable."

As Luca put it, "If you don’t run those, fine. If you do, you’re swapping one lost sale for another." You might get recommendations, but lose out on capturing interest for genuinely unavailable items. If you go this route, you absolutely must pair it with very clear communication on your product page itself. Add text like "Ships in X weeks" or "Pre-order for March delivery" right in the product description to manage customer expectations.

A More Granular Approach: Separate Product Listings

One of the most creative and robust solutions came from DanielAnderson, who runs a competing AI sales agent and has wrestled with this exact problem. Daniel suggested that instead of trying to hack the "Continue selling" flag, we should think differently about how we list these products.

His approach is to stop treating future allocations as "out of stock" at all. Instead, he recommends listing the incoming vintage or batch as its own distinct product. For example, instead of marking your current "2021 Barolo" as backorderable, you'd create a new product: "2022 Barolo, arriving March."

Here’s why this works so well:

1. Honest Inventory: You can accurately assign the actual allocation you expect for the "2022 Barolo" product. The inventory numbers stay truthful.
2. Agent Friendly: Since it’s a distinct product with genuine (future) stock, the Inbox agent sees it as available and will surface it in recommendations.
3. Preserves "Notify Me" Flows: Your original "2021 Barolo" product, if truly sold out, can still trigger your "Notify Me" flows without interference. Customers get accurate updates on what's genuinely gone.
4. Clear Customer Communication: The product title itself informs the customer exactly what they're buying and when to expect it.

This strategy does mean a bit more product management upfront, but it offers a much cleaner and more accurate way to handle backorders without compromising other critical parts of your sales funnel. It allows you to tailor your Shopify setup to your specific business needs, ensuring you're getting the most out of every feature, including AI sales agents. If you're looking to refine your store's operations and ensure every part of your customer journey is optimized, exploring how different Shopify features interact is key. Many successful merchants have built robust stores by understanding these nuances. If you're just starting out or looking to upgrade your current setup, remember that a strong foundation on a platform like Shopify can make all the difference. You can start building your dream store with Shopify today and then dive into these advanced inventory strategies as you grow.

What We Really Need: Better Merchant Control

Ultimately, as robinthebest and Icey.Lane pointed out, the ideal solution would be more granular control directly from Shopify. We need:

• A dedicated setting to include all published products in agent results, regardless of stock level.
• Or, a specific flag to mark products as orderable, separate from their actual "on hand" inventory count.

This kind of flexibility would empower merchants to manage backorders and pre-sales much more elegantly. Ecom_swift_LLC rightly suggested that we should all be filing feedback via the in-app Inbox settings. The more merchants who voice this need, especially with specific examples, the more likely it is to get on Shopify's roadmap. Icey.Lane even gave a great tip for escalation: "capture one exact query, the published variant, continue selling state, the missing recommendation, and proof that the same variant can be added to cart." This gives Shopify a reproducible discovery failure, which is gold for their development teams.

So, while we wait for those ideal features, you now have a couple of solid strategies to ensure your valuable backorder products aren't hiding from your Shopify Inbox agent. Whether you choose the "Proceed with Caution" toggle or the "Separate Product Listing" method, remember that clear communication with your customers is always paramount. Happy selling!
