Payment Gateway Shopify Apps – Analytics & Insights

UnumPay ranks #1 for payment gateway with 9.2% share — the leader position in a fragmented field where many apps are within striking distance, 9.2pp ahead of Cashfree BNPL Plus (0). Smart Way sits at #3 with 0.5% share, rounding out the top tier. The top 3 apps together hold only 9.8% — meaning payment gateway is a fragmented market where lower-ranked apps still capture significant share. Smart Way is the standout mover this month, climbing 3 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.

Payment Gateway is a fragmented market — the top 3 apps together hold only 9.8% of installs, leaving UnumPay's 9.2% lead modest in absolute terms and Smart Way at 0.5% still capturing meaningful share. With this many viable apps, pricing model and integration depth differentiate payment gateway options more than rank does.

UnumPay climbed from #5 (Sep 2025) to #1 (Sep 2026) — a 4-position gain among payment gateway apps over the charted window. Across the top 5 plotted payment gateway apps, 3 improved their ranking while 1 declined — the category is moving upward overall. UnumPay's share expanded +8.7pp from 0.6% (Sep 2025) to 9.2% (Sep 2026) — a sustained widening of the gap against other payment gateway apps over this window.

A 4-position move for the leader over the charted payment gateway window is large enough to reflect real merchant adoption shifts, not just App Store noise — UnumPay's climb as of Sep 2026 is the strongest trajectory signal in this chart.

United States is the largest single market for payment gateway apps at 17.5% — but no country dominates, meaning payment gateway apps serve a globally distributed merchant base. India follows at 13.9%, with Pakistan at 9.8%. Together, the top 3 markets account for 41.2% of payment gateway app installs worldwide. United Kingdom (6.6%) and France (5.2%) round out the top 5. Pakistan is the fastest-growing market this month (+5.8pp), pointing to accelerating demand outside the established leaders.

With United States's 17.5% as the largest single market and the rest spread across many countries, the leading payment gateway apps tend to be region-agnostic by design — geography matters less for app choice here than features, pricing, and support quality.

Essential Trust Badges & Icons is the only app in this set to have crossed 1,000 reviews, reaching the milestone in 36 months since launch. The remaining 4 payment gateway apps tracked here are still building toward 1,000 — current cumulative review counts give the clearest picture of where each one stands today.

4 apps on this chart haven't yet crossed 1,000 reviews: Hyve ‑ Post to Xero at 44, UnumPay at 26, Cashfree BNPL Plus at 1, Smart Way at 1 cumulative reviews. Hyve ‑ Post to Xero is closest to the milestone — its current count puts it roughly 4% of the way to 1,000.

Essential Trust Badges & Icons is the only app in this set to have crossed 1,000 reviews so far — a useful signal for merchants that one app has already proved sustained adoption while the others remain in the "promising but unproven" tier of the payment gateway category.
