What is allocation in fashion retail and wholesale?
Allocation is the process of deciding how much of each product, size and colour goes to which store, channel or customer from the available stock.
In short
Allocation is the decision of how available inventory is split across stores, online channels and wholesale customers, down to size and colour level. In fashion it determines whether each location gets enough of the right products to sell at full price without being overstocked.
How does it work in practice?
An allocator or merchandiser starts with the total quantity bought and the store or channel plan. Initial allocation sends a first push of stock before launch, while a reserve is usually kept in the distribution centre for later replenishment. Rules consider store grades, space, climate, local demand history and size profiles.
- Initial allocation: the first distribution at season launch or for a new drop.
- Reserve stock: quantities held back to react to early sell-through.
- Rebalancing: moving stock between stores or from retail to online as demand becomes clear.
In wholesale, allocation also applies when supply falls short of orders, for example when a factory delivers less than booked and a brand must decide which accounts receive full quantities.
Why does it matter for fashion businesses?
Fashion has short selling windows and many size and colour combinations. Poor allocation leaves popular sizes sold out in one store while the same items sit unsold elsewhere, which leads to lost sales and markdowns at the same time. Good allocation protects margin and improves the customer experience across channels.
How is AI changing it?
Machine learning models forecast demand per store, size and week using sales history, product attributes, weather and local events. Optimisation engines then recommend quantities that respect constraints such as pack sizes and transport costs. The most useful systems explain their recommendations so allocators can override them where they know local context.
Common pitfalls
Typical issues include using one size curve for all locations, allocating everything up front with no reserve, and ignoring returns and online demand in the same region.
Frequently asked questions
What is the difference between allocation and replenishment?
Allocation is the decision of how stock is distributed, especially the first distribution of new products. Replenishment is the ongoing process of topping up stock as it sells, often using rules or forecasts.
Who is responsible for allocation in a fashion company?
Usually an allocation or merchandise planning team, working with buyers and the supply chain. In smaller brands the merchandiser often handles it alongside other planning tasks.
