Is Cin7 Core worth it for my Shopify store?
Shopify is switching Stocky off on 31 August 2026.
If that means nothing to you, stay with me, because the question underneath it is one every growing store hits eventually. If it means rather a lot to you, you already know you've got a decision to make. Either way, the deadline is a good excuse to ask something bigger than "what replaces Stocky?" The real question is where your inventory should actually live.
Stocky was never really about your online store.
Stocky was Shopify's purchasing and stock-counting companion for Shopify POS. It was built for physical retail: multi-location shops, regular buying from suppliers, receiving stock, stocktakes, and some basic demand forecasting. If you run a counter as well as a website, you might have leaned on it heavily. If you're purely online, you might never have touched it.
So why does its retirement matter to a Shopify store owner who isn't running tills? Because of what it exposes. Stocky going away is Shopify pulling its inventory tools back into the core platform, and that draws a clear line around what Shopify does and doesn't do with your stock. Once you can see that line, you can see whether you've already crossed it.
After 31 August, Stocky doesn't go read-only. It goes dark. No purchase orders, no supplier records, no forecasting. And one thing genuinely catches people out: some of that data, your supplier details especially, can't be cleanly exported. If you don't capture it before the lights go out, it's gone. So if you're still on Stocky, that's your near-term job regardless of what you decide next.
First, the honest part. You might not need much.
I'm not going to pretend every Shopify store needs a separate inventory system. Plenty don't, and the people telling you that include Shopify themselves.
A lot of what Stocky did now lives natively in Shopify Admin: transfers, stock adjustments, low-stock alerts, purchase orders, supplier records, and a couple of newer reports that give you a proper audit trail of stock movements. For a store doing straightforward buying and receiving, that's often enough on its own.
Where native Shopify runs thin is the cleverer stuff: automated forecasting, suggested reorder quantities, min and max levels per location, and reporting by the supplier you actually buy from. That's the gap the Shopify-native apps fill. Prediko is a good Admin-first option for forecasting and purchase orders. Pimsical suits stores that do their receiving on the shop floor through POS. EasyScan is the budget-friendly pick if you mostly want barcoding and simple ordering without the forecasting. They're good tools that do a real job.
Before you buy anything, ask yourself one question: "Replace Stocky for what?"
"We need an inventory app" isn't a brief, but "We keep guessing reorder quantities and we want margin reporting by supplier" is. Once you know the actual job, the right answer usually picks itself. And often the right answer is native Shopify plus one of those apps, for somewhere between roughly USD $60 and USD $300 a month. Stocky was free, which is a tough act to follow. More on the money shortly.
If that's you, brilliant. You don't need us, and you don't need Cin7 Core. Spend the money on the app and get on with your day. Maybe spend your saved time watching Andor, it's fantastic!
Now the part the apps can't fix.
A native app sits inside Shopify and treats Shopify as the centre of your world. That's the whole appeal. It also works right up until Shopify stops being the only place your stock lives. The moment your inventory reality gets bigger than your storefront, an app bolted onto that storefront starts to strain.
You'll feel it when:
Your true cost of goods isn't just a buy price. You assemble or manufacture products from components, and the cost of every piece that goes in needs to land correctly, or your margins are fiction.
You sell through more than Shopify. A retail counter, wholesale, a marketplace, a second region. Each one needs to know what's actually in stock right now, and they keep disagreeing.
You're running wholesale or B2B alongside your DTC store, with different pricing, terms, and order workflows.
You're holding stock in more than one place and the counts never quite match.
None of that is a Shopify problem. Shopify is a very good place to sell. It just isn't trying to be the brain that runs purchasing, production, costing, and multi-channel stock across your whole business. When that's the job, you've outgrown patching the storefront.
Yes, Cin7 Core means Shopify stops being your source of truth. Good.
This is the line you'll hear used as a warning, often from service providers and Shopify partners whose expertise sits with the storefront rather than higher-complexity inventory workflows and the requirements that come with them. So let's take it head-on.
The standard caution about a system like Cin7 Core is that it takes over as your source of truth, and Shopify drops to being one sales channel among several. That's completely accurate. It's also, for a growing business, the entire point.
I use a spider analogy to explain it because I'm in Australia and they are our overlords, demanding praise and positive attention. Cin7 Core is the body and brain. It holds the central functions: inventory, purchasing, production, costing, and the financial picture that sits on top. Your apps and channels are the legs. Shopify is a leg. A good, strong, important leg, but a leg. Each one reaches out to do a specific job, and the body keeps the truth in one place so the legs don't have to argue about it.
For a single-store retailer, putting the truth outside Shopify is a faff they don't need. For a business selling in five places, you really don't want the master record of your stock living inside one of the five. You want it sitting above all of them. That isn't a downgrade for Shopify. It's Shopify finally only having to do the thing it's brilliant at.
So, is it worth the money?
Right, the actual question.
Cin7 Core's subscription starts at USD $349 a month for the Standard tier and runs to USD $999 for Advanced, with most product businesses landing on Pro at USD $599. Pay annually and you get a month free. On top of that, there's the cost of setting it up properly, which varies a lot with complexity. I won't rehash all of that here. I wrote a full breakdown of what Cin7 Core costs to implement, numbers, timelines and all.
What I'll do instead is reframe the comparison, because "USD $599 a month versus a free app that's going away" is the wrong sum. The honest comparison is the cost of the system against the cost of the mess it clears up.
So run the maths on your own store. Say stock counts drift between your channels and you oversell, quietly, on a small share of orders. Just 2% of 1,000 orders a month is 20 orders you can't cleanly fulfil. Refunds, apology emails, expedited restocks, a few customers who don't come back. That last one is the costly part, and I've written before about what bad customer service and systems actually cost you. Put a conservative USD $40 on each of those in cost and lost margin, and that's USD $800 a month gone, on a problem you can't even see. At 5,000 orders a month it's USD $4,000. Then add the dead stock you bought because nobody could forecast properly, and the hours your team loses every week reconciling spreadsheets that disagree with each other.
Measured against that, the subscription is rarely the expensive number. The mess could be bloody costly.
That doesn't make Cin7 Core worth it for everyone. It's worth it when the mess is real and growing: when your COGS can't be trusted, when channels fight over stock, when manufacturing or wholesale adds complexity an app was never built to hold. If none of that is biting yet, it isn't worth it, and I'd tell you so to your face.
The short version.
Stocky switching off on 31 August is a prompt, not an emergency. If you use it, export your data and capture your suppliers now, because some of it can't be recovered later. Then ask the bigger question. For a lot of Shopify stores, the right move is native Shopify plus a forecasting and purchasing app like Prediko or Pimsical, and that's a genuinely good answer for somewhere around USD $60 to USD $300 a month. Cin7 Core earns its keep when you've outgrown that: when you need accurate cost of goods, when you assemble or manufacture, when you sell wholesale, or when you sell across several channels and need one place to hold the truth. At that point, Shopify stops being your source of truth and becomes a sales channel, and for that kind of business, it's exactly the right trade. The subscription starts at USD $349 a month. The question isn't whether that's cheap. It's whether it costs less than the mess you're living with.
If you're not sure which side of that line you're on, get in touch. We'll give you a straight answer, even if the answer is "stick with a Shopify app."
