Purchase Orders Shopify Apps — Frequently Asked Questions
1. Which purchase orders app has the highest market share on Shopify?
Stockie Inventory Management ranks #1 by share among purchase orders apps at 76.5%, but the market is fragmented — multiple apps capture meaningful share. Compare the top 5 on features and pricing before deciding.
2. How is market share calculated for purchase orders Shopify apps?
For purchase orders (a keyword page), market share is rank-weighted — apps at position #1 carry roughly 40× the weight of apps at position #22, and apps beyond #22 are excluded. Each app's weighted score is divided by the total weighted score across the keyword to give the share %. This reflects Shopify search behaviour: most installs come from the top of the results.
3. Which purchase orders apps are gaining market share on Shopify?
Stockie Inventory Management is gaining purchase orders app market share fastest this month, up +9.38pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
4. Which purchase orders apps are losing market share on Shopify?
EasyScan Inventory & Barcode has lost the most market share this month among purchase orders apps (-11.68pp). Sort the table by Change (Low to High) to see the full list of decliners.
5. Which countries drive the most purchase orders Shopify app installs?
United States drives the largest share of purchase orders app installs at 50.3%, followed by United Kingdom at 12.9% and Australia at 9.8%. Use the country picker on the third card to compare market leaders by country.
6. How many purchase orders apps does ShopDigest track on Shopify?
ShopDigest tracks 96 purchase orders apps on the Shopify App Store. Market share, rankings, and review data refresh weekly so you can track competitive shifts as they happen.
7. Why does the highest-share purchase orders app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under purchase orders (driven by Shopify's own algorithm), while market share on ShopDigest is estimated from review counts and other factors as a proxy for active installs. The two metrics move on independent dynamics, so the highest-share app and the #1-ranked app are not always the same — and a divergence between them is worth noting rather than assuming one will pull the other along. For purchase orders, Stockie Inventory Management leads on share; see the rankings tab for who currently holds #1 position.
