Companies Using authorize.net

A gateway ranked against the card logos it processes

authorize.net is 18th in Payment Processing on 0.10% share, sitting below PayPal, Apple Pay, Shop Pay, Visa and Mastercard. There is a particular absurdity in the last of those, because authorize.net is owned by Visa. The category places a subsidiary 14 places below its parent, and the two rows are not even measuring the same kind of thing: one counts checkouts that display a card logo, the other counts merchants who wired a gateway into their payment flow.

The useful comparison is against other gateways in the market authorize.net actually serves. 87.42% of its geolocated companies are in the United States, the highest single-country concentration of any payment technology TechnologyChecker.io publishes. Restrict the category to US companies and the order is Stripe on 56,626, Square on 4,760, authorize.net on 4,649, Braintree on 945.

Third in the United States, effectively tied with Square, and about a twelfth of Stripe. That is a more honest description of authorize.net in 2026 than any global percentage.

The age curve is the real finding

Most technologies we profile have a lopsided founding-year distribution. authorize.net's is almost flat: 24.44% of matched companies founded in the 2010s, 22.43% in the 2000s, 14.36% in the 1990s, 10.70% in the 1980s, 7.28% in the 1970s, 9.59% before 1960. Compare that to Recharge, where 78.59% post-date 2010.

Two readings fit. The generous one is that authorize.net has been selling since 1996 and its base reflects three decades of accumulation. The harder one is in the 2020s row: 7.20%, the second-smallest bucket in the distribution. A product winning its fair share of new businesses would show a fatter recent cohort, because new businesses are being founded faster than old ones are dying. This installed base is durable, not growing.

Where the enterprise names actually live

Tyson Foods, Toyota, Citroën, Supermicro, Lincoln Electric, Kettering Health Network, the University of Pittsburgh. That list would suggest authorize.net is an enterprise gateway until you read the detection URLs next to it: merch.tysonfoods.com, autoparts.toyota.com, store.supermicro.com, classes.lincolnelectric.com, events.kansashealthsystem.com, ce.lsu.edu.

Not one is a corporate homepage. Every one is a side commerce surface: employee merchandise, a parts catalogue, event registration, continuing education. These are the properties large organisations build quickly, run on modest stacks, and leave alone. The gateway decision there is made by whoever built the store, not by group treasury, which is why authorize.net can appear at Toyota without being Toyota's payments provider in any meaningful sense.

Reading a detection without reading its URL is how a parts catalogue becomes an enterprise reference customer.

Veterinary practices at the top of a payments list

Combine the two labels our company data uses for the same sector and Veterinary Services is the largest industry on this page at 11.05%, ahead of Retail at 8.33%. That is not a quirk of sampling. Veterinary practices take deposits, sell prescription food, bill for procedures, and do all of it through practice-management software that has supported authorize.net for twenty years.

Research Services at 3.80%, Wholesale at 2.93% and Motor Vehicle Manufacturing at 2.06% are the same story in different clothes. The common factor is that the payment page hangs off an operational system. Nobody in those organisations wakes up wanting to change gateway, because the change is an integration project rather than a settings page.

Nobody is leaving, they are just adding Stripe

We publish no migration corridors on this profile, and the measurement behind that decision is the most striking number on the page. Of the domains that have ever run both authorize.net and Stripe, 94.5% still run both today. That is the highest coexistence rate we have recorded between two payment technologies.

The raw query does return switch pairs, 27 in the observed window. Publishing those as a migration would tell you that authorize.net is losing merchants to Stripe. What the population actually shows is merchants running both: the old integration keeps handling what it always handled, and Stripe takes the new subscription flow or the new mobile checkout. That is a slower and less dramatic fate than displacement, and it is what the data supports.

The stack corroborates the age profile

jQuery on 74.78% of domains and jQuery Migrate on 33.17% is a specific signal. jQuery Migrate exists to keep old jQuery code running against newer versions, so a third of these sites are carrying compatibility shims. Bootstrap on 46.79% and WordPress on 26.60% round out a picture of sites built competently some years ago and maintained since.

None of that is criticism. A veterinary practice does not need a rewritten frontend. But it does explain why the gateway is stable: the sites around it are stable too.

What to take from this

If you are evaluating authorize.net, the relevant question is not whether it is behind Stripe on features, because it is. It is whether your payment flow is embedded in an operational system that already supports it, in which case the integration cost of moving is the real number to weigh. If you are starting fresh in 2026, the 7.20% figure for companies founded in the 2020s tells you what your peers are choosing.

And if you are looking at this page to size an enterprise opportunity, check the subdomains first. TechnologyChecker.io counts domains, and on this profile a striking number of the large ones are side storefronts rather than the businesses whose names they carry.
