Vat Shopify Apps — Frequently Asked Questions
1. Which vat app has the highest market share on Shopify?
Order Printer Pro: PDF Invoice ranks #1 by share among vat apps at 68.9%, 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 vat Shopify apps?
For vat (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.

6. How many vat apps does ShopDigest track on Shopify?
ShopDigest tracks 96 vat 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 vat app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under vat (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 vat, Order Printer Pro: PDF Invoice leads on share; see the rankings tab for who currently holds #1 position.
