I’m currently running a Shopify store and also selling on Amazon, and inventory management has started getting messy as we grow.
Right now I’m mainly looking for a tool that can handle both:
Inventory management across Shopify + Amazon
Inventory replenishment / restock planning
Low stock alerts and stocktaking would be helpful too
I’ve tried managing things manually and with spreadsheets, but it’s becoming difficult to keep stock accurate across channels and know when to reorder inventory.
Would love to know what tools other multi-channel sellers here are using and what’s actually working well for you. Any recommendations?
We were still using spreadsheets for this last year and it got rough once Amazon started moving inventory faster. Half the problem was just not trusting the stock numbers anymore between channels, especially before reorders. A couple times we thought we had enough stock and then Amazon wiped it out overnight.
This is very common stage once store start scalling across channels. Manual tracking works up to a point, but Shopify + Amazon usually needs a centralized inventory system because stock mismatches and delayed reordering become expensive quickly.
From what you described, I’d separate the problem into two parts:
Inventory syns across channels → Shopify + Amazon Stock accuracy, low stock alerts, stocktakes etc.
Inventory planning → Forecasting demand and knowing how much to reorder.
For tools I’ve seen Cin7 work well when businesses need stronger operational control and multi-channel inventory syncing.
If replenishment forecasting is the bigger pain point, inventory planner is worth looking at become it focuses more on forecasting and purchasing decisions.
SkuVault is another option if stock accuracy and warehouse workflows are becomming difficult.
If this was helpful, don’t forget to like it and mark as Solution.
Once Amazon is in the mix, I’ve found the harder issue is usually that FBA demand and Shopify demand behave differently enough that blended forecasting starts to break down.
Are you mostly FBA, FBM, or split, and do you forecast them separately or together right now?
You can try Sumtracker, it provides all the features that you are asking for plus many more features like PO management, supplier management, stock transfer and adjustment, all in one place.
I have checked Cin7 and it is just too pricey for us at this stage. I looked at Skuvault (I think it’s linnworks now?) is more for warehouse operations and it has feature we don’t require at all. I want a simpler tool not some heavy one. Thanks for you time tho mate:)
There are a lot of tools that handle both Shopify and Amazon as I’m trying different tools now but yes finding the right one is the problem because most of these are too pricey
Nventory handles exactly this - real-time Shopify + Amazon sync, low stock alerts, and restock planning in one place. Worth a look before it becomes a bigger headache.
A method that I see quite a few multi channel sore owners using is automating the syncing of inventory from each channel into a single spreadsheet or BigQuery data set. You can either use the raw data, or create a dashboard based on this data in Looker Studio / Power BI (pretty simple and very cost effective. Look into apps like SyncRange, SuperMetrics etc. to connect that data.
once you’re selling on both shopify and amazon, spreadsheets fall apart fast because by the time you update one channel the other is already out of sync. that’s basically the number one complaint i see from people managing multichannel.
for shopify + amazon specifically, look at Inventory Planner or the Marketplace Connect app. the key thing is making sure it does real-time sync between channels, not batch updates, because overselling on amazon when shopify already sold the last unit is a nightmare to fix. also make sure whatever you pick handles reorder points per channel separately since your velocity on amazon vs your own store will be totally different.
Hey @woysanstore , have you considered a “Ghost App” approach? If the core value is mainly moving and syncing data seamlessly, the best app might actually be no app at all. Instead of building and maintaining a frontend, everything happens entirely in the backend via APIs. It completely removes the friction of user downloads and App Store approvals, leaving you with a seamless background sync.
As a junior dev shipping, I’m really curious to get some insights on this from both sides. Merchants, would you trust an app that has no visible interface? And devs, what are the biggest technical or scaling challenges you’ve run into when handling syncing entirely in the backend?
