Tired of Inventory Headaches? Build Your Own Custom Stock Take App with Shopify Sidekick!

Hey everyone! As a Shopify migration expert, I’ve heard countless stories about the joys and pains of running an online store. One topic that consistently comes up, and often causes the most headaches, is inventory management. Keeping track of stock, especially when you’re growing, can feel like a never-ending battle against discrepancies. That’s why a recent conversation in the Shopify community really caught my eye – it showcased a fantastic, innovative way to tackle stock takes using Shopify’s very own AI assistant, Sidekick.

The discussion kicked off around the idea of a "Free Simple Stock Take app." We all know there are many apps out there, but sometimes you just need something tailored, something that does exactly what you need without all the extra bells and whistles (and recurring costs!). That’s where our community member, Jaxonday, stepped in with a brilliant solution: using Sidekick to build a custom, simple stock take app.

The Power of Sidekick: Community Insights

Before diving into the app itself, it’s worth noting that the thread also featured some interesting observations about Sidekick. Maximus3, another community member, shared their experience, calling Sidekick "very helpful" but acknowledging its inconsistencies. They mentioned how it can be "a miracle worker" one day and "nitpick all the minute dom leaks" the next, especially with code analysis. This is a great point: AI tools are evolving rapidly, and while they're incredibly powerful, they sometimes have their quirks. But the takeaway is clear: Sidekick is a tool that can help you do some "pretty cool stuff," and it’s constantly being improved, as Maximus3 also noted with the addition of deleting conversations.

Jaxonday’s initial attempt to share the app code involved multiple posts, which Laza_Binaery rightly pointed out was "really hard to follow." This kind of feedback is invaluable in a community! Jaxonday quickly adapted, moving the code to Pastebin, making it much easier for everyone to access. This is a perfect example of community collaboration leading to a better outcome.

Your Own Custom Stock Take App: What It Does

So, what exactly did Jaxonday create with Sidekick? It’s a custom app designed to simplify your stock take process, especially if you organize your inventory by collections. Here’s the gist:

  • Collection-Based Scanning: You can create a collection (e.g., "Stock Take - Warehouse Section A") and then scan the barcodes of items that should be in that collection.
  • Discrepancy Detection: The app will show you any differences between what Shopify thinks you have and what you’ve actually counted.
  • Inventory Adjustment: Once you're confident in your count, you can adjust your Shopify inventory directly through the app.
  • Customizable: This is a huge win! Because it’s built with Sidekick, you can ask Sidekick to add features you need – like taking stock at different locations or adding items by SKU instead of just scanning barcodes.
  • CSV Export: You can export your counts to a CSV file for your records or further analysis.

It’s important to understand what it isn’t: it’s not a full-blown inventory management system. It’s a focused, customizable tool for stock takes. Also, a key limitation is that it only works in the Shopify Admin in a web browser, not the mobile app.

Get Started: How to Implement and Use Your Sidekick App

Ready to try it out? Here’s how you can get this custom app up and running in your own Shopify admin, based on Jaxonday’s excellent instructions:

1. Get the Code

First things first, you’ll need the code. Jaxonday has generously shared it on Pastebin. You can find it here: Stock Take - Pastebin.com. Just copy all the code from that page.

2. Generate the App with Sidekick

This is where Sidekick truly shines. It makes building a custom tool surprisingly accessible.

  1. Open your Shopify Admin.
  2. Locate Sidekick (usually in the bottom right or via the search bar).
  3. Click the plus (+) icon in the "Ask anything" box.
  4. Select "Generate app."
  5. Paste the code you copied from Pastebin into the dialog box that appears.

Sidekick will then work its magic and create the custom app within your admin!

3. Customize It (If You Want!)

This is the fun part! If you need additional features, don’t be shy:

  • Simply ask Sidekick to add them. For example, "Add the ability to do takes at different locations" or "Allow me to add items from SKU along with scanning barcodes." Sidekick will rewrite the code to incorporate your requests.

4. Using Your New Stock Take App – Step-by-Step

Once the app is generated, here’s how to use it for your stock takes:

  1. Create a new Stock Take or select an "Active Session" from a previous one you’ve already started. You can name it whatever you want.

  7. Click the "select all" box, then click "Apply to Inventory."
