Composed products: manage your kits without phantom stock and never forget a component

Why managing composed products correctly is essential
When a product is sold, shipped or consumed as an assembly:
Phantom stock
Giving the kit its own stock creates an impossible-to-reconcile double count.
Forgotten component
Shipping a kit without decrementing its parts skews the entire inventory.
False availability
Promising a kit with a missing component leads to a stock-out mid-order.
The limits of manual kit management
Many organizations still manage their assemblies with:
Result:
- ✗Kit availability never up to date
- ✗Components decremented by hand (or forgotten)
- ✗Recurring inventory discrepancies
- ✗No trace of what was assembled
Stock that no longer reflects reality.
GSE-Web: composed products with
Enabling and configuring composed products
The module is enabled in one click, then each kit is defined in seconds.
Kit composition
Add components via real-time product search
Component stock
- Keyboard 100
- Mouse 50
- Screen 150
Availability always follows the most limiting component
Module rules
- The composed product has no stock of its own
- A component cannot itself be a kit (1 level)
Stock behavior automatically adapted
availability calculated in real time
Availability calculated from the components
For each kit, GSE-Web continuously calculates the number of possible assemblies.
The calculation is simple and fully transparent:
Availability always reflects the limiting component.

Entries and exits: automatic explosion
Every movement on a kit is reflected on its components in three steps:
Kit entry
You record a movement on the composed product, exactly like a normal product.
This movement is:
- ✓ recorded
- ✓ checked
- ✓ logged
Disponibilité
Availability (the minimum across components) is checked before any write.

Zero double entry, zero oversight.
Track every assembly
Full traceability of assemblies
Every kit explosion is logged end to end:

a kit is never split
Precise, multi-warehouse availability
Across multiple sites, a kit is never split across two warehouses.
- Availability calculated warehouse by warehouse
- Sum of possible assemblies per site
- Perfect consistency of global stock

Before each movement, GSE-Web shows the detail of the component movements that will be generated.
- ✓ List of impacted components
- ✓ Calculated quantities
- ✓ Confirmation before writing
No surprises: you validate fully informed.
Use cases across every sector
The composed product fits any assembly, kit or bundle activity.
E-commerce kits
Industrial sets
Bundles and lots
Assembly on demand
One mechanism, whatever your business.
Immediate visibility on your kits
At any time, you must be able to answer:
"How many kits can I assemble?"
"Which component limits me?"
"What did this kit exit generate?"
With GSE-Web:
At a glance, you get:
Zero calculation, zero doubt.

Frequently asked questions
What is a composed product (virtual kit) in GSE-Web?
A composed product is an item with no stock of its own, defined by a bill of materials. Its availability is calculated from the stock of its components.
How is a kit's availability calculated?
GSE-Web takes the minimum, component by component, of available stock divided by the quantity required per assembly. The most limiting component sets the number of possible assemblies.
What happens to stock on a kit entry or exit?
The movement automatically explodes onto the components: entering or removing a kit increments or decrements each component per the bill of materials, with no double entry.
