The Bottom Line
If you're a DTC brand with 100-2000 SKUs and want straightforward inventory forecasting without paying enterprise prices, Alertr is worth trying. It tracks sell rates per SKU, estimates when products will run out, and sends reorder alerts automatically — all for $19/mo (locked in forever for early adopters).
Trunk takes a different approach to inventory management. The right choice depends on whether you need those extras or whether focused forecasting and alerts at a lower price gets the job done.
Both apps install directly from the Shopify App Store. Alertr offers a free tier (50 SKUs) and a 14-day trial on Pro, so you can test it with real data before committing.
