| App | Price/mo | Best for | Watch out for |
|---|---|---|---|
| Supply Radar | Free–$19 flat | Single-location stores that want alerts + POs, nothing else | No forecasting, no stocktakes, single-location focus in v1 |
| Shopify native POs | Free | Occasional restocks, tiny catalogs | No reorder points, no alerts |
| Sensible | ~$29 | Simple ops teams wanting forecasting | More than lightweight options if you skip the forecasts |
| Forstock | ~$39 | Forecast-driven buying, seasonal catalogs | Can be overkill under ~500 SKUs |
| Prediko | ~$49+ | Multi-channel brands with a buyer/planner | Priced for scale-ups |
| Sumtracker | ~$59+ | Multi-store, bundles/kits, marketplace sync | Highest price in this cluster |
This is most ex-Stocky users. The core loop is: know when to reorder, make the PO, receive the stock. Supply Radar covers exactly this — realtime low-stock alerts, auto-suggested reorder points, and one-click supplier POs — at $9–19/mo flat with a free plan (5 alert rules) and 14-day trial. If that's your whole workflow, paying for a forecasting suite is buying features you'll never open.
Sensible and Forstock are built around demand forecasting and buy planning. If you order seasonally, buy far ahead, or your cash flow depends on getting order quantities right months out, this tier earns its price. Supply Radar is honestly not the right pick here — its suggestions are based on recent sales velocity, not long-horizon forecasts.
Prediko and Sumtracker target brands with real inventory operations: multiple warehouses, marketplace channels, bundles and kits. They cost the most because they replace the most. If you're here, also expect a longer setup than the 10-minute migrations the lightweight tier advertises.
Shopify's native draft purchase orders plus a calendar reminder might genuinely cover you. The gap you'll feel is silent stockouts — nothing alerts you. A free plan with a few alert rules on your bestsellers (Supply Radar's free tier, for instance) is a zero-cost hedge for exactly that.
Export your suppliers and open purchase orders from Stocky before August 31 — step-by-step instructions here. Every app on this list can import or re-create that data; none of them can recover it after the shutdown.
