Payment Processing Market Data
Adoption and 30-day momentum across 100 payment processing technologies, measured from our live detection crawl.
Biggest Movers
Expert Insight: Payment Processors Market Share & Momentum
The top seven all fell together, which means storefronts closing, not merchants switching.
PayPal, Apple Pay and Shop Pay each sit on 15-19% of the 8.0M live sites where we detect a payment method, and the top five hold about 71%. Over the latest 30 days every one of the top seven lost between 22,000 and 34,000 net domains, in near lockstep. When Visa, Mastercard and American Express move by the same number, you're watching checkout pages disappear, not processors being replaced.
Wallets and card badges dominate detection
PayPal (~19%), Apple Pay (~16%), Shop Pay (~15%) and Google Pay (~9%) are what checkouts expose to a crawler; the card networks (Visa, Mastercard, Amex at 10-11% each) are logo badges, not processors. Stripe, the largest pure processor, is at about 2.5%: hosted checkouts that redirect off-site leave less on the merchant's page for us to detect than a wallet button does.
Klarna Checkout is the only sizeable gainer
Klarna Checkout added about 15,000 net domains in 30 days (24,200 adopted, 9,200 dropped) and about 22,000 over 90 days. Nothing else in the top 20 grew by more than a couple of hundred. Buy-now-pay-later at checkout is the one adoption story in an otherwise shrinking category.
Lockstep losses
Apple Pay -33,700, PayPal -31,600, Shop Pay -31,500, Visa -26,100, Mastercard -26,100, Amex -24,300, Google Pay -21,900: seven vendors, one shape. Shopify storefronts carry most of these buttons and badges together, and Shopify itself dropped from about 106,000 domains in the same window. This is store attrition and crawl coverage moving, not seven independent churn events. Don't read it as PayPal losing to Apple Pay.
Net negative on both windows
Payment detection is down about 193,000 net domains over 30 days and 170,000 over 90. Because it moves with the ecommerce platform base, treat payment share as a ratio, not a count: the ranking is stable even while every absolute number falls.

Payment Processing
FAQ.
What is Payment Processing software?
Payment Processing covers the tools a site can load or configure to handle this part of its stack. We detect one of the 100 payment processing tools in this category on 8,236,654 live sites. A detection means we found the technology on the site, which is not the same as a paid account.
What are the most popular payment processing platforms?
Across 8,236,654 detected sites, the most widely found payment processing tools are: PayPal (19.13% share, 1,575,738 sites), Apple Pay (15.46% share, 1,273,419 sites), Shop Pay (14.61% share, 1,203,619 sites). Others we see regularly include Visa and Mastercard.

PayPal is the most widely detected payment processing tool at 19.13% share, on 1,575,738 sites. The largest share of those sites belongs to Retail companies, and to businesses in the 1-10 employee band.
Which industries use payment processing software the most?
The industries with the most detected sites in this category are Retail, Retail Apparel and Fashion, Manufacturing, Food and Beverage Services, Wellness and Fitness Services. Industry mix follows where these tools get installed, so a category carried by website builders or agency templates will lean toward the verticals those platforms serve rather than the vendor's target buyer.
Which countries have the highest adoption of payment processing tools?
We detect the most payment processing sites in United States, United Kingdom, Australia, Canada, Germany. Country here is the company's registered location in our enriched data rather than where the site is served from, so read it as a ranking of markets rather than a measure of any single one.
How do I choose the right payment processing platform?
Start from your own size, industry and primary use case rather than from share. PayPal, Apple Pay and Shop Pay are the three we detect most often in this category, which tells you what is common, not what fits you. Compare their integrations, pricing tiers and support commitments against the workflow you actually run, and check each vendor's own documentation for current capabilities.
