Primer review: products, technology and pricing (2026)

Primer is a payment orchestration platform: a software layer between a merchant's checkout and its payment processors that lets the merchant connect several PSPs, fraud tools and payment methods through one integration and route payments between them without new code. Its distinctive pieces are a no-code Workflows engine for payment logic, a central vault for payment credentials and automatic fallbacks to a second processor, extended since 2025 into finance tools such as reconciliation, cost analysis and multi-currency Global Accounts.

How the platform works

Primer routes each payment to one of the processors a merchant connects, which then authorises it. It sits in front of those PSPs and acquirers and decides where each payment goes. Our payment orchestration explainer covers the general model; Primer's version works like this:

1. Checkout. The merchant adds Primer's Universal Checkout to its website or app through Primer's SDKs. Which payment methods appear, and under what conditions, is set in the Primer dashboard without code.
2. Capture and vault. Card details go into Primer's central vault, a single store for payment credentials. Primer's terms state that it holds PCI DSS certification. It can also use network tokens, which it says lift authorisation rates and cut fraud.
3. Workflow. When the payment is created, a Workflow decides what happens next: which processor to send it to, whether to run 3D Secure, which fraud check to call.
4. Authorise and fall back. The chosen processor authorises the payment. If it fails, Fallbacks can resend it to a second processor.
5. Observe and reconcile. Results feed Observability dashboards, Monitors that alert on metric changes, and Reconciliation, which standardises fees and net payouts across all PSPs.

Payments that the merchant starts later, such as subscription charges using a vaulted card, go through the Payments API and skip the checkout.

Workflows is the engine underneath. Primer describes it as built from four primitives: triggers, actions, apps and outputs. Triggers can be payment events, refunds, subscription updates or an external webhook. Conditions are defined by the merchant, for example routing by the card issuer's country or treating a first payment differently. Each run leaves a trace showing the path taken, step timings and data passed between blocks, and Primer says the engine has handled hundreds of millions of runs.

Products

Checkout

Universal Checkout covers cards, wallets and local methods across web and mobile through one integration. A new modular Checkout, built in 2025, lets merchants add, remove and style individual fields and buttons, sitting between Primer's earlier Drop-In and Headless options.

Workflows and routing

No-code payment logic in a visual editor that arranges itself automatically. Merchants use it for routing, 3D Secure strategy and fraud checks. Our payment gateway vs PSP vs acquirer guide explains the parties a Workflow routes between.

Vault and network tokenisation

A single store for payment credentials, used across the processors a merchant connects. See our network tokenisation explainer for how scheme tokens work.

Fallbacks and 3D Secure

Fallbacks resend a failed payment to a secondary processor. Primer says more than 95% of merchants using two or more PSPs use it, and that recovery rates improved up to three times on the first version (2025). In 2025 it added more 3D Secure providers inside Workflows; it reports authorisation improvements of over 4% for some merchants from 3DS strategies. Our 3D Secure guide covers the protocol.

Observability, Monitors and AI Companion

Real-time payment data across providers, alerts on metric changes, and an AI assistant (launched 2025) that explains anomalies and suggests actions. Primer says it plans for the AI Companion to run experiments and act within limits users set (Series C announcement, 2026).

Reconciliation, Costs Overview and Global Accounts

The finance layer. Reconciliation launched fully in early 2025. Costs Overview flags fee leakage and benchmarks providers. Global Accounts, launched in 2025, gives merchants local collection accounts, FX at market-linked rates and transfers over local rails or SWIFT. For US customers, the underlying payment services are provided by Airwallex's US entity, according to Primer's product page.

Primer for Partners

A configuration-based tool that lets PSPs and other providers build their own Primer integrations without code. Primer says a PSP integration was built this way in under an hour by September 2025.

Developer experience and integrations

Primer says it offers more than 100 global integrations activated in one click (undated, checked 3 November 2026), and that it has shipped and maintains more than 140 integrations used in production (2025). One named example: J.P. Morgan Payments is available to Primer merchants for cards, Apple Pay and Google Pay, with GetYourGuide as the first user.

Payment methods, currencies and coverage

Payment method and country coverage depends on which processors a merchant connects, so Primer does not publish one list. For Global Accounts it publishes these figures (undated, checked 3 November 2026):

Primer's leadership is spread across Switzerland, France, the UK and Portugal, and the company says it expanded in Asia-Pacific in 2024. It expects the US to exceed a third of its business by 2028 (Series C announcement, 2026).

Pricing model

Primer does not publish prices on the pages we opened on 3 November 2026; its product pages direct prospects to a payments specialist. Under Primer for Growth (announcement undated; its survey data is from March 2025), qualifying startups get one year of free access to Monitors and Observability; the criteria are not published on the announcement. Primer says some merchants recover more revenue each month through Fallbacks than they pay Primer (2025).

Recent launches

Primer's blog posts do not carry exact publication dates, so we give years only.

Regulation in brief

Primer's standard terms are issued by Primer API Limited under English law and state that Primer holds PCI DSS certification. On the pages we opened, Primer does not describe itself as a licensed payment institution; payments are authorised by the processors merchants connect. For Global Accounts, Primer states that US payment services are provided by Airwallex US, LLC, a licensed money transmitter in most US states.

Who it tends to suit

• Mid-size and enterprise merchants that use two or more PSPs and want routing, fallbacks and one view of performance.
• Businesses expanding into new regions that want to add local processors or payment methods without rebuilding checkout.
• Finance teams that need cross-PSP reconciliation and fee analysis.
• Startups that qualify for Primer for Growth.

Merchants using a single PSP may find that provider's own routing and reporting tools enough; compare our Stripe, Adyen and Checkout.com profiles, our Worldpay profile, or the gateways hub.
