How to share inventory between Shopify products
Sell the same physical stock on multiple Shopify product pages. Learn when to link inventory, how quantities work, and how to set up shared stock.
Sell it three ways.
Count it once.
LinkStock keeps Shopify listings that sell the same physical units on one Available Quantity, separately at each Location.
Free for up to 9 linked items. Setup reads your inventory and changes nothing.

Hamburg keeps its own count: 6
- Main listingInventory Item 1 of 318
- Autumn campaignInventory Item 2 of 318
- Gift editionInventory Item 3 of 318
All 3 listings share 18 available at Berlin. Sell one on any listing to see the others follow.
Four decisions.
All of them yours.
Shopify counts every listing on its own. LinkStock links the ones that sell from the same shelf, after you’ve checked them.
- 1
Install. LinkStock reads your inventory.
The initial import brings in products, Inventory Items and Locations. It doesn’t change a single quantity.
- 2
Choose the Locations that take part.
Each participating Location keeps its own count. Decide how a new group starts when quantities differ: Let me decide, Use lowest stock or Use highest stock.
- 3
Link the listings that share stock.
Search by product, variant, SKU or barcode, or start from a suggestion. Inventory Items take part at Locations where they’re already stocked.
- 4
Review the starting quantity, then enable.Stock changes start here.
From then on, a movement on any linked listing sets the group’s next shared quantity, and the other listings follow.
Your catalog already has the hints.
Inventory Items that share a SKU or barcode arrive as suggested groups. A match is a reason to look, not proof of shared stock, so nothing is linked until you’ve reviewed every item. When labels differ, build the group by hand.

Shopify stays in charge.
LinkStock changes one number, in the groups you enable, at the Locations you choose. This is the whole boundary.
LinkStock
- Reads before it writes.The initial import shows your inventory and changes no stock.
- Changes stock only in groups you enable.Nothing moves until you review a group and switch it on.
- Aligns one number: Available Quantity.The quantity your linked listings sell from.
- Treats each Location on its own.A sale in Berlin never changes the count in Hamburg.
- Lets you pause.Stop one Stock Group, or synchronization for the whole shop.
- Keeps a record.30 days of Activity History, with recovery tools for anything that needs attention.
LinkStock doesn’t
- Add the listings’ quantities together.Three listings showing 18 are 18 units, not 54.
- Transfer stock between Locations.There is no pooling and no borrowing.
- Create inventory at a Location.Only Inventory Items already stocked there take part.
- Change other inventory quantities.On hand, committed and the rest are left to Shopify.
- Handle bundles, kits or ratio packs.A group shares one count, one unit for one unit.
- Sync separate stores.Every Stock Group lives inside one Shopify store.
Synchronization is asynchronous. LinkStock responds to verified inventory movements reported by Shopify. Completion time isn’t guaranteed.
Pay for linked items.
Nothing else.
A linked item is one Inventory Item in a Stock Group. Plans differ only in how many you can link.

All guidesHow to sync duplicate SKUs in one Shopify store
Matching SKUs do not link Shopify inventory automatically. Check whether listings share physical stock, review suggested groups, and sync the right items.
Questions, answered.
Will setup change my Shopify stock?
No. The initial import and setup do not change stock levels. Creating and enabling Stock Groups is a separate step; review their starting quantities before confirming.
Read in the FAQDoes LinkStock add the quantities together?
A group represents one physical stock pool per location. Three linked listings with 12 available represent the same 12 units, not 36 units. Review the starting quantity rule when existing quantities differ.
Read in the FAQDo linked items need the same SKU?
No. You choose the Inventory Items in a Stock Group. SKUs and barcodes help with search and suggestions, but they are not the identity used for group membership.
Read in the FAQCan I use multiple locations?
Yes. Each participating location synchronizes independently. LinkStock does not transfer or combine stock between locations.
Read in the FAQWhy does an item say “Not stocked”?
Shopify has no inventory assignment for that item at that location. This is different from zero stock. Manage the assignment in Shopify; LinkStock does not create it.
Read in the FAQCan I pay yearly?
Yes. Paid plans offer yearly billing with two months free: pay the equivalent of ten monthly payments upfront for a year. The linked item limits and features are the same for monthly and yearly billing. Choose your billing frequency on Shopify’s plan selection page.

Setup changes no stock. Paid plans include a 14-day trial.
