Stripe and Authorize.net are both major online payment processors, but they come from different eras of fintech. Authorize.net launched in 1996 and is now owned by Visa. Stripe launched in 2011 and redefined payment integration with its developer-first approach. Their transaction rates are identical, but the total cost of ownership differs significantly.
Transaction Fees
Both Stripe and Authorize.net charge 2.9% + $0.30 per online transaction. On the surface, they're identically priced. But Authorize.net adds a $25/month gateway fee that Stripe doesn't charge. Over a year, that's $300 in fixed costs before you process a single payment. For businesses with low transaction volumes, this monthly fee makes Authorize.net meaningfully more expensive.
eCheck and ACH
Stripe offers ACH Direct Debit at 0.8% capped at $5. Authorize.net charges $0.75 per eCheck transaction. For small payments, Authorize.net's flat fee is competitive, but for larger invoices, Stripe's percentage model with a $5 cap is more predictable. On a $1,000 B2B payment, Stripe charges $5.00 and Authorize.net charges $0.75 — a rare win for Authorize.net.
Developer Experience
Stripe's API is considered the gold standard for payment integrations. Modern RESTful design, comprehensive documentation, interactive examples, and robust webhooks. Authorize.net's API is functional but dated, with XML-based messaging that feels legacy compared to Stripe's JSON-first approach. Most developers strongly prefer working with Stripe, which translates to faster integration, lower development costs, and easier maintenance.
When Authorize.net Makes Sense
Authorize.net's primary advantage is its long track record and Visa backing, which appeals to risk-averse enterprises. Some legacy systems are already integrated with Authorize.net, and switching costs can outweigh the benefits. If your business already runs on Authorize.net and doesn't need Stripe's modern features, the migration may not be worth the effort. For new projects, Stripe is almost always the better choice.
