Purchase Orders Shopify Apps – Analytics & Insights

Stockroom ‑ Purchase Orders ranks #1 for purchase orders with 0 share — the leader position in a fragmented field where many apps are within striking distance, -67.5pp ahead of Stockie Inventory Management (67.5%). Auto Purchase Orders sits at #3 with 1.6% share, rounding out the top tier. The top 3 apps together control 69.0% of purchase orders installs — a clear leadership tier with a meaningful long tail behind them. Prediko Inventory Management is the standout mover this month, climbing 7 positions — a momentum signal worth tracking. Worth noting: the top-ranked app and the highest-share app aren't the same here — App Store rank and our market share metric (computed from review counts and other factors) move on independent dynamics, so cross-checking both views matters in this category.

Purchase Orders is a fragmented market — the top 3 apps together hold only 69.0% of installs, leaving Stockroom ‑ Purchase Orders's 0 lead modest in absolute terms and Auto Purchase Orders at 1.6% still capturing meaningful share. With this many viable apps, pricing model and integration depth differentiate purchase orders options more than rank does.
