Pay.net vs Primer: Multi-Rail Gateway vs Payment Orchestration Layer

Orchestration Layer vs Native Multi-Rail Processor

Primer doesn't move money. It's a routing and workflow layer that connects to PSPs a merchant already has contracts with — Stripe, Adyen, Braintree, Checkout.com, and others — and lets them build no-code rules to failover between providers, A/B test acquirers, and unify reporting across those existing relationships. The underlying processing, settlement, and compliance still belong to whichever PSP Primer routes the transaction to.

Pay.net is a single native processor. It processes cards and bank rails directly and adds FedNow, RTP, SEPA Instant, SWIFT, PIX, UPI, and stablecoin settlement on top, with AI-powered routing choosing the cheapest, fastest, safest rail per transaction from one merchant relationship — no separate PSP contracts required underneath it.

For a merchant already running multiple PSPs who wants vendor-agnostic failover across contracts they've already negotiated, Primer's orchestration-only model is purpose-built for that. For a merchant who'd rather not hold multiple PSP contracts at all, Pay.net covers the same routing benefit with one processing relationship.

Feature Comparison at a Glance

What Primer Actually Offers

Primer's core insight is that large merchants often already run 2-4 PSPs for redundancy, geographic coverage, or negotiating leverage — and stitching those together with custom code is expensive to build and maintain. Primer abstracts that into one API and a visual workflow builder: define rules like "route to Adyen first, failover to Stripe on decline, A/B test a new acquirer on 5% of traffic," without writing routing logic per provider.

This makes Primer a strong fit for larger merchants who already hold PSP contracts and want a vendor-agnostic layer on top — reducing acquirer lock-in and downtime risk — without changing who actually processes and settles their funds.

Where Primer Leads

True Multi-PSP Vendor Independence

Because Primer doesn't process payments itself, a merchant can add, remove, or reweight PSPs without any migration — it's purpose-built for avoiding acquirer lock-in. Pay.net is itself a single native processor, so it doesn't offer this specific kind of PSP-swapping flexibility across third-party providers.

No-Code Workflow Builder

Primer's visual workflow builder for defining routing rules, retries, and 3DS logic without engineering time is a dedicated, mature product surface. Pay.net's routing is AI-driven and automatic across its own native rails, but doesn't expose an equivalent no-code rule editor for third-party PSP orchestration.

Unified Reporting Across Existing Providers

For merchants who already have data spread across multiple PSP dashboards, Primer's aggregated reporting layer solves a real operational pain point. Pay.net doesn't need to solve this problem the same way, since it's a single provider by design — but that also means it isn't useful for aggregating data from PSPs a merchant is already running outside Pay.net.

Where Pay.net Leads

No Underlying PSP Contracts Required

Primer's orchestration only works on top of PSPs a merchant already holds contracts, underwriting, and compliance relationships with — it doesn't remove that overhead, it routes across it. Pay.net is a single processing relationship covering cards, bank rails, and beyond, with no separate contracts to negotiate or maintain underneath it.

Native FedNow, RTP, and Stablecoin Rails

Primer's rail coverage is a function of which PSPs it's connected to — if none of those PSPs support FedNow, RTP, or stablecoin settlement, Primer has no way to route to them. Pay.net processes all three natively, independent of any third-party PSP's own rail roadmap.

Single Fraud & Risk Surface with a Guarantee

Pay.net's Fraud.net-powered engine applies one consistent fraud model across every rail, backed by a contractual guarantee of losses below 2 basis points. Primer's fraud outcomes vary by whichever underlying PSP handled a given transaction, since each PSP brings its own risk engine and liability terms.

Simpler Pricing Model

Primer's total cost is its own orchestration fee stacked on top of whatever each connected PSP separately charges — the effective blended rate depends on the underlying PSP mix. Pay.net publishes a single per-rail rate card with no separate orchestration layer to price in.

The Right Setup Depends on Whether You Already Run Multiple PSPs

The decision usually comes down to where a merchant is starting from:

• Already running 2+ PSPs, need vendor-agnostic failover, and want to keep negotiating leverage across acquirers: Primer's orchestration-only model is purpose-built for exactly this, without disturbing existing processing relationships
• Starting fresh, want native FedNow/stablecoin rails, or don't want to hold multiple PSP contracts: Pay.net's single native relationship covers the routing benefit without the multi-contract overhead
• Combined: Some merchants run Primer across their existing card PSPs for redundancy while using Pay.net directly for bank-rail, FedNow, or stablecoin flows those PSPs don't support

When to Choose Primer

• You already hold contracts with 2+ PSPs and want a vendor-agnostic routing/failover layer on top
• A no-code workflow builder for routing rules and A/B testing acquirers is a priority
• Unified reporting across multiple existing PSP dashboards is your main operational pain point
• You want to preserve negotiating leverage across acquirers rather than consolidating to one

When to Choose Pay.net

• You'd rather not hold multiple PSP contracts at all — one processing relationship covers cards and bank rails
• FedNow or RTP real-time settlement matters, independent of any third-party PSP's rail coverage
• Stablecoin settlement matters for cross-border collections
• A single, contractually-guaranteed fraud model across every rail rather than one that varies by underlying PSP
• Transparent, single-rate-card pricing without an orchestration fee stacked on top of separate PSP fees

Frequently Asked Questions

Does Primer process payments itself?

No. Primer is an orchestration layer that sits on top of PSPs you already hold contracts with (Stripe, Adyen, Braintree, and others) and routes transactions between them via one API and no-code workflows. It does not settle funds or move money on its own rails. Pay.net natively processes cards and bank rails itself, so there's no separate PSP contract or settlement relationship required underneath it.

Is Pay.net a replacement for Primer?

For merchants already running 2+ PSPs who need vendor-agnostic failover, A/B routing between existing providers, and a single workflow layer across contracts they already hold, Primer's orchestration-only model is purpose-built for exactly that. Pay.net is the better fit for merchants who don't want to negotiate and maintain separate PSP contracts at all — it's a single processor covering cards, ACH, FedNow, RTP, SEPA, SWIFT, PIX, UPI, and stablecoin natively.

Which is better for real-time bank rails like FedNow?

Primer's routing depends on the underlying PSPs connected to it — if none of those PSPs support FedNow or RTP, Primer can't route to them regardless of its own orchestration logic. Pay.net processes FedNow and RTP natively, settling in under 5 seconds, independent of any third-party PSP's rail coverage.

Which platform has lower total integration overhead?

Primer still requires a merchant to hold and maintain individual contracts, underwriting, and compliance relationships with each PSP it orchestrates across — Primer adds a routing layer on top, not a replacement for those contracts. Pay.net is a single merchant-of-record-style processing relationship covering every rail, which removes the multi-contract overhead entirely for merchants who don't specifically need multi-PSP redundancy.
