RKR LinkStock: Shared stock between products, combinations and packs in PrestaShop (EU B2B, 0% VAT)

It links items that originate from the same physical unit (the same garment in two collections, a single item and its packaging, a size M dress and its outlet listing) so that a sale deducts the stock of all items. It offers three strategies, shared stock notifications on the listing, historical data and statistics, multi-store functionality, and six languages. It also includes a Rekire module.

Compatible with PrestaShop 1.7.8 to 9.2.

Black Friday, 7 to 30 November: spend €50 or more on modules (VAT included) and we give you a €200 voucher (VAT included) to spend on more modules for one month. Ends in until 30 November at 23:59.

Shared stock

If you sell the same unit on two different listings, the stock is misleading.

The same garment in two collections, a single item and its pack, a size M dress and its outlet listing: each listing has its own stock, and a sale doesn't affect the others. You end up selling what you no longer have. RKR LinkStock links these listings so that a sale reduces the stock of all of them.

/ Cases he/she solves

The same garment in two collections
You have the shirt in "Summer" and "Basics" with two entries. You link them and, wherever you sell, both show what's left.
Single item and 3-pack
Each member has their own ratio: if you sell 2 packs of 3 sheets, the price of a single sheet drops by 6 units. A shared supply of physical units feeds everyone.
Size M dress and its outlet listing
With "minimal mirroring," sales or restocking in either system are reflected in the other. If you restock one, the other receives the same amount.
Master warehouse item
With "master-directed", the master is the source of truth: when you sell a derivative publication, it is discounted from the master and projected to the rest.

Three ways to share, one per case

Shared reserve : a pool of physical units from which each member consumes according to their ratio; what each token can sell is the reserve divided by its ratio. Mirror minimum : the member who changes sets the limit, and their quantity is copied to the others; the group's minimum is only used when recalculating. Master-directed : the master token's stock is projected to the rest.

Groups are organized by warehouse and master SKU, and you can limit them to a single store or apply them to all stores in a multi-store setup. Sales, cancellations, and returns move the group, and you can choose whether manual stock edits are also synchronized.

What your customer sees

The product page displays a "Shared Stock" notice with linked listings: image, name, price, stock availability (or number of units, if enabled), and a link to view them. It also includes a unique title and note for each language, a choice of visual effects, and 23 themes with live previews to match your design.

/ Safety: Never break an order

The order continues even if the synchronization fails.
The entire synchronization process is protected: if something fails, PrestaShop still completes the sale and the order is not interrupted.
Orders at once, without losing units
The reservation is deducted with a single atomic operation in the database, so two simultaneous orders don't overlap. Neither do two lines within the same order.
Without overselling
By default, the reserve does not go below zero; if you prefer to allow sales without stock, it is an option that you activate.

/ Control and data in the back-office

Group manager and tab in the card
List of groups, member manager with image and an "RKR LinkStock" tab within each product's information sheet.
Statistics and historical data
Indicators, 5 charts and an activity history that distinguishes sales, manual edits and recalculations, with export to CSV.
Import and export
Groups and members in CSV format, and a full copy in JSON format to transfer the configuration from one store to another.
Low stock alerts
Threshold per group and email notification when a reservation falls short.
Optional chronograph
A URL with a 32-character secret key, regenerable, that recalculates all groups, cleans up orphaned members, and deletes expired records.
Demonstration data
One button to install an example with all the strategies and another to remove it; your real catalog is never touched.

Before we begin, try this example: install it, see how the stock drops in the linked listings, and delete it with one click. Without touching your products.
