IRIS vs Excel for retail replenishment

When a spreadsheet stops working, and what replaces it

Most distributors we meet order from Excel. It works well up to a point: one planner, a few thousand references, ten stores. This page lays out, without exaggeration, where the spreadsheet breaks and what IRIS does differently.

Excel is not the problem. The problem is what a spreadsheet cannot do once the network grows: refresh from the ERP several times a day, forecast at shade level, track lots, allocate testers, and write orders back without retyping.

When Excel is still the right tool

  • Fewer than five stores and a few hundred references

  • One planner who knows every product and supplier

  • No lots, no testers, no launches with marketing calendars

  • An ERP that cannot export stock and sales automatically

What the switch looks like

Four weeks: connect the ERP or a CSV export, calibrate on your history, run IRIS in parallel with the spreadsheet for a week, then go live with approval thresholds. Your planner keeps the final word on every order.
