Plan, allocate, replenish and execute on one live signal, so the gap between knowing and acting stops costing you margin.
A six-week proof of concept on your own data

Merchmix is a merchandising and inventory operating system with intelligence at its core. Planning, product, suppliers, warehouse, orders and reporting run on one source of truth, so nobody reconciles between four versions of the same number.
Every module runs a part of the business in its own right. Together they run the whole of retail.
Melanie Pells
Senior Marketer, Sydney, Australia

Most retailers start with Core, or Core with ARRO, and add from there. Every module you add works off the same live numbers from day one.
The trading cycle end to end. Budgets and open to buy through range build, weekly trade and the reviews that close the season.
Execution on the floor. ARRO allocates store by store and size by size, and VM carries the signed-off range into every planogram.
Design what your data already knows will sell. Tech packs, product library, materials and sourcing, with your own trading data informing what you create.
The retail-native backbone. Products, inventory, sales, purchasing and finance in one ledger, live all day with no overnight batching.
Suppliers in the system, not in your inbox. POs, ASNs, invoices and shared forecasts in one place, so suppliers see demand coming instead of discovering it in the order.
Every order takes its best route. Routing, splits, backorders and dropship handled without anyone chasing them.
The warehouse, visible as it happens. Inbound through dispatch, every movement and location tracked live.
Build the report once, never build it again. Board packs and trade packs that update on live data and distribute themselves.
Connects to NetSuite, SAP S/4HANA, Microsoft Dynamics 365, Shopify and BigQuery.

MFP, WSSI and open to buy on live numbers, so the Monday meeting is about what to do rather than whose figures are right.

Sales, stock and intake projected by week and season, on demand curves rather than last year plus a percentage.
Cover breaches, slow movers and margin pressure flagged inside the workflow, connecting to markdown management before profit is lost.
By category, product, channel, store or supplier, without exporting anything.
Range and buying decisions made against a live OTB position rather than one that was accurate a fortnight ago.

Senior Buyer, Sydney Australia

Plans, stock and actions stay live on mobile, so approvals do not wait for someone to get back to a desk. No separate licence, included as standard.
Trends, risks and opportunities surfaced while the season can still be shaped, not in the post-season review.
Performance by product, category, channel or store, in views that match how each team already thinks.
Floor plans, planograms and a 3D model of every store carry the signed-off range onto the shop floor, with compliance tracking and fixture ROI measured down to the table.

ARRO grades stores on sales, size and demand, then drives allocation, replenishment and transfers against live demand inside the limits you set.

From lean teams managing their first buy plan to multi-region retailers running complex product flows, Merchmix grows with your business.
