Planning ran on a spreadsheet and one growth rate. Stock now follows actual demand.

The problem

Planning used spreadsheets and a single growth assumption applied to everything. Popular lines ran out while slow ones sat in the warehouse tying up cash, and nobody could put a number on the trade-off between the two.

What was built

We built forecasting that works product by product and adds up consistently to category and company totals, plugged into the planning process people already used, and able to answer what-if questions.

What changed

Forecast error fell from 12.1% to 2.7%. Cash previously tied up in the wrong stock was released without more items running out, and planners now review the exceptions instead of rebuilding spreadsheets.
