The Spreadsheet Problem in Demand Planning
Spreadsheets are the most common starting point for demand planning — and the most common bottleneck. For brands with under 50 SKUs and simple, stable demand, Excel works. But once you cross that threshold, spreadsheets become a liability: manual data entry errors, broken VLOOKUP formulas, missed seasonality, and hours spent maintaining models that still don't prevent stockouts or overstock.

Frequently Asked Questions
Can I use Excel for demand planning?
Excel works for small catalogs (under 50 SKUs) with simple, stable demand. Beyond that, spreadsheets become unmanageable: formulas break, seasonality is missed, and updates require hours of manual work. AI-powered demand planning like Integer Demand automates the entire process and scales to thousands of SKUs.
What are the limitations of spreadsheets for demand planning?
Four major limitations: (1) Don't scale beyond ~50 SKUs; (2) No automatic seasonality detection; (3) Require constant manual data entry; (4) No automated PO generation — purchase orders must be calculated manually.
How much time does Integer Demand save vs Excel?
Most brands report saving 8–15 hours per week after switching. The biggest gains come from automated data ingestion, AI-generated forecasts, and automated PO recommendations.
