Allocation & replenishment
Stock belongs where it can sell.
The first split follows store grade, size curve and capacity. Later refills use a model per style, with local overrides. Inspect quantities before approval.

An even split can miss demand.
Allocation and replenishment software decides how much stock each store gets, size by size, and when to top it up. Mid-market retailers run 10+ systems before merchmix. An old grade can leave stock where demand is weaker while another branch sells out.
Each store merits a considered quantity.
Grading, line-level review and transfers address different parts of the distribution job.
Grading
A revenue-by-size grid assigns locations to cells with buy grades. Outliers show a suggested position and reason before you use their grade in a split.

Questions, answered.
What is allocation and replenishment software?
It decides where stock goes and when it is topped up. Allocation sends the first quantity of a new line to each store. Replenishment keeps those stores in stock as the season trades.
What is the difference between allocation and replenishment?
Allocation is the first push of a line to stores, split by store grade, size curve and capacity. Replenishment is the in-season top-up that follows, driven by what each store sells. In merchmix both run in core plus, against the same stock position.
How does merchmix compare with specialist tools and enterprise suites?
Specialist allocation tools sit on top of the planning and ERP systems you already run. Enterprise suites cover everything, at enterprise cost and timelines. merchmix runs allocation and replenishment in the same platform as planning and buying, rather than a layer on top of what is already there. 1/10 the cost of enterprise suites, live in 12 to 15 weeks.
What happens to our ERP?
It stays the system of record. merchmix reads from it, and anything written back is approved first and logged.
Who built merchmix?
People who ran planning at M&S and ASOS. merchmix is one platform for planning, buying, allocation and stock, built for mid-market retailers.
Can I change a recommended allocation?
Yes. Adjust line-level quantities, carry decisions and statuses before approval or fulfilment.
Can I test a different distribution first?
Yes. What-if scenarios preview quantities without immediately changing live allocations. Commit the approved decision afterward.
Can one store differ from the global rule?
Yes. Per-store overrides sit alongside global replenishment rules.
Can I export the result?
Yes. Export detailed allocation data or supplier-facing allocation files after review.
Real locations make allocation testable.
