Quick Answer

Head-to-Head Comparison
Stripe is a modern full-stack payment platform combining payment processing, gateway, and developer APIs in one product with flat-rate pricing and no mandatory monthly fee on standard accounts.

Considerations
Advantages and considerations are based on publicly available information. Verify all details directly with each provider.
Stripe is generally better for new businesses — self-serve signup, modern API, no mandatory monthly fee, and all-in-one processing and gateway in one relationship. Authorize.net is more commonly chosen by established businesses migrating from older systems or using software with existing integrations.
Authorize.net is a payment gateway — it routes transactions but typically requires a separate merchant account. Stripe combines the payment gateway and processing into one product with no separate merchant account needed. For most businesses building online payments today, Stripe's all-in-one approach is simpler.
Authorize.net charges a gateway monthly fee in addition to transaction fees. If you pair it with a separate merchant account, you may have additional fees from that provider too. Verify the full fee structure at authorize.net.
Authorize.net (a Visa company) has broad underwriting but does not specialize in high-risk categories. Businesses in higher-risk industries may find more specialized options through ISOs that work specifically with high-risk merchant accounts. Verify directly with Authorize.net whether your business type is eligible.
Authorize.net has a long history and is integrated into many established ecommerce platforms and CMSs. Stripe has grown rapidly and is now integrated into most modern platforms as well. For newer platforms, Stripe integrations are generally better maintained.
Authorize.net offers an all-in-one option that includes processing, but traditionally it is a gateway-only product. If you want simplicity without a separate merchant account, Stripe or Square are more straightforward choices.
