merchmix

For retail teams planning in spreadsheets · compared with Excel

Excel holds the plan. merchmix runs it.

Your WSSI (MFP), OTB and weekly trade views live in Excel because nothing else kept up. merchmix takes those same views and makes them live: sales, stock, intake and OTB update themselves, everyone works from one version of the truth, and a decision becomes a PO, an allocation or a markdown without leaving the system.

The file was never the problem.

  1. Stale on arrivalEvery view is an export, and every export is already out of date. You trade this week on last week's truth.
  2. Four versions of finalSomewhere there is a file called FINAL_v7_ACTUAL. One file per person, one truth per file, and version control eats the meeting before decisions even start.
  3. A plan that cannot actThe decision lives in a cell. Getting it into the business means retyping it into three other systems and hoping. A spreadsheet cannot raise a PO, push an allocation or flag that a size curve broke while everyone was asleep.

merchmix and Excel

The same views, live, with action built in.

Spreadsheets earned their place. They are flexible, familiar, and every merchandiser on earth can build one. What they cannot do is stay live, agree with each other, or act on the business. merchmix keeps the views your team already trusts, the WSSI, the OTB, the weekly trade grid, in the editable grid format they already work in, and connects them to real sales, stock and intake, with approvals, an audit trail and execution built in. And when you still want a file, it exports to Excel.

core

From first signal to shop floor.

core is the commercial engine of merchmix: budgets, planning, range building and daily trade in one place, reading years of your sales history alongside live signals from every connected system. Every view below is one your team has tried to build in a workbook. Here they are live, connected, and writing back to your ERP, OMS or Shopify.

  1. Direction

    The season usually starts with last year's file, copied forward and adjusted by hand. merchmix starts it by reading years of sales history alongside live market signals, showing where growth can come from and what is holding it back. You open the season pointed at opportunity, not at a template.

  2. Budget

    No more targets pasted into a tab and reconciled by email. Growth direction becomes commercial targets: sales, GP, stock investment and OTB, down to category level. One budget, one version, agreed once and carried through every stage that follows.

  3. Control

    This is the WSSI you already run, without the exports. The budget becomes a weekly sales, stock and intake plan that updates itself, continuity protects your never-out lines before gaps become lost sales, and every change stays connected to the numbers you signed off.

  5. Moments

    Trading moments and marketing spend are planned against the same numbers as the range, not in a separate calendar file. The calendar and the buy never disagree, and every promotion and drop lands against stock that is actually there.

One platform, built to grow with you.

merchmix helps your team plan what to buy, put stock where demand is, and keep the shop floor selling. Every product stands alone: buy one, buy a few, or run the whole platform. Most retailers start with core, because that is where it hurts.

Every product stands alone. Start with the one that hurts most.

Nothing gets ripped out.

merchmix connects to the systems you already use, giving teams one live view of sales, stock, orders, suppliers and store performance. Your ERP, POS and ecommerce tools keep doing their jobs, and the exports your team used to run by hand become feeds that run themselves.

Bring your existing plans with you: upload your Excel and CSV files to get started, and export any view back out whenever you need a file.

merchmix is shaped by retail operators, not outside observers. The founding team spent years inside retail brands running budgets, WSSI, OTB, range planning, allocation and daily trade, and for most of those years the tool was a spreadsheet. merchmix is the system they wished the file could be.

Start with the workflow that hurts most, for most teams that is the WSSI, then add more as the business grows.

Questions, answered.

What is the best alternative to Excel for retail planning?

A retail platform that keeps the same planning views live. merchmix connects WSSI (MFP), OTB, range planning, allocation and weekly trade to real sales, stock and intake, so plans update themselves and decisions execute in the system instead of living in files.

Can I build a WSSI in Excel?

Yes, and most merchandising teams have. The limits show up in trade: exports go stale, versions multiply, and the file cannot act on the business. merchmix runs the same weekly sales, stock and intake structure as a live view with approvals and a full audit trail.

What is the difference between WSSI and MFP?

They describe the same discipline. WSSI, weekly sales stock and intake, is the UK and European term; MFP, merchandise financial planning, is the US one. merchmix runs both as one live planning grid.

Does merchmix replace Excel?

It replaces the jobs Excel was never built for: live planning, version control, approvals and execution. Any view still exports to Excel whenever your team wants a file for offline analysis.

How does data get in without manual exports?

Through connectors across ERP, POS, ecommerce and supplier systems, sales, stock and intake feed in automatically. Your ERP stays the system of record, with approval-first write-back.

Do we lose the flexibility of spreadsheets?

Spreadsheets stay ideal for one-off analysis and scratch work, and that is where they should stay. merchmix takes over the repeatable operating views, the WSSI, the OTB, weekly trade, where flexibility without version control is exactly what breaks.

What does moving off spreadsheets involve?

Less than replacing a system, because there is no system to replace. merchmix connects to the stack you already run, your existing plans upload via Excel and CSV as the starting point, and teams typically start with the workflow that hurts most, then add products as the business grows.

Why do retailers move off spreadsheets for merchandise planning?

Version control, stale exports, error risk, and no route from decision to execution. The plan is usually good. The problem is that a file cannot see the business or act on it.

Is merchmix hard to learn for a team that lives in Excel?

No. The planning views are editable grids, week-by-week rows with TY vs LY vs LY-1 alongside, the same shape as the WSSI your team already runs. What changes is what sits behind the grid: live data, approvals and a route from every decision to execution.

Retire the file, keep the discipline.
