GST Pro: GST Invoice India dominates the sst filing category on Shopify with 67.7% of installs — 50.2pp ahead of TaxCloud Sales Tax Automation. This is a clear leader by share, so most merchants default to it unless they have a niche-fit reason to pick differently.
For sst filing (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.
Numeral Sales Tax is gaining sst filing app market share fastest this month, up +3.12pp versus 30 days ago. Switch the table sub-tab to "Market Share Changes" to see all gainers ordered by movement.
TaxCloud Sales Tax Automation has lost the most market share this month among sst filing apps (-4.59pp). Sort the table by Change (Low to High) to see the full list of decliners.

ShopDigest tracks 96 sst filing apps on the Shopify App Store. Market share, rankings, and review data refresh weekly so you can track competitive shifts as they happen.
Rank reflects an app's current position in the Shopify App Store under sst filing (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 sst filing, GST Pro: GST Invoice India leads on share; see the rankings tab for who currently holds #1 position.
