Reactive — Demand Planning Software for Fashion Brands That Outgrew Spreadsheets
Demand planning software for $5M–$100M apparel brands that outgrew spreadsheets but can’t justify Toolio. Replaces spreadsheet guesswork with transparent math. Built for planners, not analysts.
Key Features
52-Week Demand Outlook — EWMA-weighted velocity with seasonal curves per category. Demand quality filters detect trailing dropoffs and spikes so the planning horizon reflects healthy demand, not noise.
Reorder Recommendations — Critical and Soon signals calibrated to your lead time and safety stock. MOQ and carton pack rounding applied. Surfaced in-app (push-notification panel on the Q3 roadmap).
Weeks of Cover — Live inventory runway, seasonality-adjusted. Color-coded red, yellow, green, blue so you see risk at a glance.
Price Sensitivity & Markdown Simulator — Log-log regression auto-calibrates price sensitivity per category. Model any markdown to see velocity lift, GM impact, and projected sell-through.
Promo Planner — Plan promotional events across your assortment. Set discount type, duration, and scope. See per-style lift, GM erosion, inventory risk, and post-promo demand dip before you commit.
Size-Level PO Exports — ISSR builds size curves from your own sales data. PO quantities broken by size with largest-remainder rounding.
OTB Budget Control — Set a dollar cap on planned spend. Real-time budget bar prevents accidental overbuy.
Sell-Through Tracking — Set a target sell-through percentage by week. Styles that miss the mark get flagged automatically.
Inventory Turns & GMROI — Measures how fast inventory converts to revenue and return on inventory investment.
Cannibalization Alerts — When a new launch pulls sales from existing styles, Reactive flags the velocity drop.
Markdown-Only Demand Detection — Flags styles that only sell at a discount before you reorder at a margin that doesn't exist.
How It Works
Upload your sell-through CSV with style-level weekly data (units sold, inventory, price). Reactive builds a 52-week demand outlook, flags reorder needs, and generates size-level purchase orders. Setup takes hours, not weeks — no integrations or IT department required. Google Sheets and Shopify auto-sync rolling out Q3.
Pricing
Growth plan: $499/month billed monthly, or $299/month billed annually (save 40%). 14-day free trial. No contracts, cancel anytime.
Who Is It For?
Reactive is built for $5M–$100M apparel brands with a dedicated planner or buyer who currently runs the assortment in Excel. Replaces spreadsheet guesswork with transparent math — at a fraction of the cost of tools like Anaplan or Toolio. Not a fit for brands under $3M revenue, non-apparel categories, or teams looking for a full ERP replacement.
