Fluid Pay is not affiliated with, endorsed by, or sponsored by Authorize.Net or Visa Inc. Authorize.Net is a registered trademark of CyberSource Corporation, a Visa company. Information about Authorize.Net was compiled from publicly available materials as of the date above and may change.

Authorize.Net is the gateway most partners cut their teeth on. It has been shipping since 1996, was acquired by Visa via CyberSource, and probably has more "AIM integration" code in production today than any other payments API. That ecosystem is real and it is worth respecting.

This page is for partners weighing whether the next phase of their portfolio should stay on the incumbent or move to a partner-only platform built around modern APIs and a structural non-compete.

The short version: Authorize.Net is a great gateway for direct merchants and a competent gateway for resellers. Fluid Pay is a partner-only platform that ships under your brand by default. The biggest decision drivers in practice are non-compete, white-label, native surcharging, and the cost of unwinding legacy AIM/SIM/CIM integrations.

The matrix below covers what partners actually compare on.

  • Non-compete commitment

    The trait competitors cannot match without restructuring the business.

    Fluid Pay
    Structural: Fluid Pay does not sell to merchants directly. Partner-only since 2017.
    Authorize.Net
    Owned by Visa via CyberSource. No partner non-compete; merchants can sign up directly through Authorize.Net's website.
  • Deployment model
    Fluid Pay
    Cloud-native, multi-region, single REST API for CP and CNP.
    Authorize.Net
    Mature cloud gateway; product surface is broad with both modern and legacy APIs in active use.
  • Omnichannel (CP + CNP)
    Fluid Pay
    Card-present, ecommerce, recurring, and vault on one stack and one dashboard.
    Authorize.Net
    Strong CNP heritage; CP via in-person SDKs and partner-integrated terminals.
  • White-label / private label
    Fluid Pay
    Full white-label included: custom domain, logo, colors, hosted pages, branded merchant portal.
    Authorize.Net
    Limited white-label. Merchants log in to the Authorize.Net portal under the Authorize.Net brand.
  • Processor relationships
    Fluid Pay
    Multiple processor connections; you keep your acquirer relationship and residuals.
    Authorize.Net
    Processor-agnostic for transaction routing; merchant-of-record relationships and direct sign-up funnel coexist with reseller programs.
  • Residual ownership
    Fluid Pay
    Partner owns the merchant relationship and residual. Fluid Pay charges flat partner pricing.
    Authorize.Net
    Reseller programs exist; many merchants come in through Authorize.Net's direct funnel and are not partner-owned.
  • Fee transparency
    Fluid Pay
    Partner-negotiated pricing that has held steady for years. Core gateway capabilities are bundled - no per-feature unlocks as the merchant book grows.
    Authorize.Net
    Public list pricing for direct merchant plans; reseller pricing is partner-program-specific.
  • Vault & tokenization portability
    Fluid Pay
    Network tokens supported. Vault export available to your acquirer or backup gateway on request.
    Authorize.Net
    Customer Information Manager (CIM) tokenization. Export terms vary.
  • Recurring & subscription engine
    Fluid Pay
    Native subscription engine with retry logic, dunning, smart card updater, and partner reporting.
    Authorize.Net
    Automated Recurring Billing (ARB) with subscription scheduling; dunning and updater depth varies by plan.
  • Fraud (Watchdog / advanced fraud)
    Fluid Pay
    Watchdog fraud module included with rules, velocity, BIN/IP intelligence, and 3DS routing.
    Authorize.Net
    Advanced Fraud Detection Suite (AFDS) included; deeper risk tooling via Visa risk products.
  • Surcharging / dual pricing
    Fluid Pay
    Compliant surcharging and dual pricing built into the gateway, no third-party module required.
    Authorize.Net
    No native surcharging engine; typically requires a partner integration or merchant-side handling.
  • EMV / device support
    Fluid Pay
    Cloud EMV with curated device list (PAX, Ingenico, Dejavoo); branded TMS for partners.
    Authorize.Net
    EMV support via the In-Person SDK and partner devices; device coverage depends on integrator.
  • API & webhook breadth
    Fluid Pay
    REST + JSON, idempotency keys, signed webhooks with retry, full sandbox parity.
    Authorize.Net
    Modern REST API alongside the long-standing AIM, SIM, and XML APIs that partner code often still depends on.
  • Sandbox & developer docs
    Fluid Pay
    Public sandbox with full API parity; docs at sandbox.fluidpay.com/docs.
    Authorize.Net
    Public sandbox and developer center; mature documentation with extensive sample code.
  • Support model
    Fluid Pay
    Direct partner support with named integration engineer during onboarding.
    Authorize.Net
    Tiered support; reseller-tier support distinct from direct merchant support queues.

Where Fluid Pay is the right pick

Fluid Pay is the cleaner choice when the merchant relationship and the brand on the portal both belong to the partner, not the gateway. With Authorize.Net, merchants log into a portal that says "Authorize.Net" at the top. With Fluid Pay, merchants log into a portal that says your brand at the top. For ISVs whose product is the merchant experience, that difference is not cosmetic.

Fluid Pay is also the right pick when you need surcharging or dual pricing without buying a separate product. Authorize.Net does not ship a native surcharging engine, so partners assemble a stack of third-party plugins or push the work to merchant-side code. Fluid Pay handles compliance, display, and reporting natively.

Partners also pick Fluid Pay when they want to stop maintaining legacy AIM and SIM call sites. Authorize.Net's modern REST API is good, but most production code partners inherit was written against the older XML and form-post APIs. Fluid Pay is REST-only with idempotency keys and signed webhooks, which removes a category of edge cases that legacy AIM/SIM code tends to hide.

Finally, partners pick Fluid Pay for stable, partner-collaborative pricing. Authorize.Net publishes direct-merchant rate cards but negotiates reseller pricing privately. Fluid Pay also keeps partner pricing private, but our pricing has held steady for years and we work with partners on the model rather than push periodic rate adjustments. The Fluid Pay quote also covers gateway, white-label portal, recurring, vault, Watchdog fraud, and native surcharging in one bundle - so the TCO conversation is less about chasing add-ons after the fact.

Where Authorize.Net is the right pick

If your stack has deep AIM, SIM, or CIM integrations across many code paths, the switching cost may exceed the partner-experience benefit even when the matrix favors Fluid Pay on individual rows. The pragmatic answer is sometimes "stay on Authorize.Net for this portfolio, build new portfolios on Fluid Pay."

Authorize.Net is also the right pick when your merchants specifically request the Authorize.Net brand. Some verticals - healthcare billing platforms, certain B2B portals, established ecommerce shops - have customers who recognize and trust the Authorize.Net name and view the brand as a reliability signal. That is a real advantage and we do not pretend otherwise.

Stay on Authorize.Net if you depend on Visa-tied risk products that flow through CyberSource and Authorize.Net's pipeline, or if your engineering roadmap depends on the largest ecosystem of pre-built shopping-cart plugins and SDKs Authorize.Net has accumulated over its history. Fluid Pay's plugin ecosystem is partner-built and growing, but it is not 25 years deep.

Pricing and total cost of ownership

Authorize.Net publishes direct-merchant pricing for gateway-only and all-in-one plans, and runs reseller programs with negotiated pricing for partners. Fluid Pay does not publish a public rate card - partner pricing is negotiated and kept private. We do not have a contractual multi-year price lock in place, but our partner pricing has not changed in years; we work collaboratively with partners and stand by the model. A Fluid Pay partner quote includes gateway, white-label portal, recurring engine, vault, Watchdog fraud, surcharging and dual pricing, and partner reporting in a single price.

When you build a like-for-like model, normalize both quotes on:

  • Per-transaction gateway fee (CP and CNP separately)
  • Monthly partner minimum and per-merchant minimums
  • Vault / CIM token storage fees
  • Recurring billing - per-subscription vs per-transaction
  • Surcharging and dual pricing - native vs third-party plugin cost
  • Fraud - included AFDS / Watchdog vs upgraded risk tiers
  • 3DS, chargeback alerts, and dispute tooling
  • Terminal management and per-device fees
  • Sandbox, certification, and integration hours
  • One-time onboarding and integration assistance fees

It is common for the partner-experience benefits (white-label, native surcharging, bundled fraud and recurring, stable pricing) to dominate the spreadsheet over time, while transactional pricing is competitive between the two on most volume profiles.

Pick Fluid Pay when

You want a structural non-compete, a fully white-labeled merchant experience under your brand, native surcharging and dual pricing, a modern REST-only surface without legacy AIM/SIM baggage, and partner-owned merchant relationships with stable, partner-collaborative pricing.

Pick Authorize.Net when

You have a long-standing Authorize.Net integration that uses AIM, SIM, or CIM extensively, your merchants specifically request the Authorize.Net brand on their portal, you depend on Visa-tied risk products, or your team needs the largest ecosystem of pre-built integrations and shopping-cart plugins that Authorize.Net has accumulated over its 25+ year history.

Frequently asked questions

Is Fluid Pay a payment gateway or a payment processor?

Fluid Pay is a payment gateway and partner-first payments platform. We connect merchants, software providers, and processing relationships through one branded experience and do not sell to merchants directly.

Why does the non-compete commitment matter when comparing to Authorize.Net?

Authorize.Net is owned by Visa via CyberSource and offers direct-to-merchant sign-up alongside its reseller channel. That means a merchant can transact on Authorize.Net without a partner in the loop. Fluid Pay's structural commitment is that we never do that - every merchant runs through a partner.

Does Fluid Pay match Advanced Fraud Detection Suite (AFDS)?

Fluid Pay's Watchdog module covers the same use cases - velocity rules, BIN and IP intelligence, transaction filtering, and 3DS routing - and is included in standard partner pricing rather than offered as a separate add-on tier.

What about white-labeling? Can my merchants stop seeing the gateway brand?

Yes. White-label is a foundational Fluid Pay capability and is included for all partners. Custom domain, logo, colors, hosted payment pages, and the merchant portal itself can run under your brand.

Does Fluid Pay support surcharging and dual pricing?

Yes. Compliant surcharging and dual pricing are built into the gateway and included in standard partner pricing. Authorize.Net does not have a native surcharging engine, so partners typically bring a third-party tool when surcharging is in scope.
