Primer

Unified payments intelligence and orchestration for merchants that connect multiple processors, route and recover transactions, run checkout and vault, and reconcile across providers without Primer acting as the processor of record.

Best ForMerchants and platforms that want no-code workflows, multi-processor routing and Fallbacks, Universal Checkout, a centralized PCI vault, and observability or reconciliation across providers without Primer becoming the processor of record or PayFac.
Not ForTeams that need Primer to be the processor of record, a bank, a lender, a PayFac that underwrites and settles merchants, or a pure self-serve live start with a published buy-rate card and no sales conversation.

Sales-led unified payments infrastructure and intelligence. Primer is not the processor of record. Merchant contracts with chosen processors stay with the merchant. Live path is Get in touch, Book a call, or Book a demo. Public pricing is custom via sales, not a printed buy-rate card.

What it is

Primer is Primer API Limited’s unified payments infrastructure and intelligence platform. Live homepage title: Unified intelligence for payments | Primer. Homepage headline: Unified intelligence for payments. Homepage subcopy: Giving finance and payments teams the full picture of every transaction and the intelligence to act on it. About Us: We build payments infrastructure for the world’s most ambitious merchants; Our AI-powered Unified Payments Infrastructure allows merchants to optimize every step of the payment journey from checkout to payout. Dedicated product explainer: Unified payment infrastructure (https://primer.io/unified-payment-infrastructure). Footer copyright: Primer. Canonical marketing domain used for this listing: https://primer.io/ (HTTP 200 at research). https://www.primer.io/ also returned HTTP 200 with the same homepage at research; neither host issued a redirect to the other in header checks, so frontmatter uses the apex homepage URL printed across Privacy, Terms, and docs.

This page is Primer payments orchestration and unified payments intelligence: multi-processor connectivity, no-code Workflows and routing, Fallbacks recovery, Universal Checkout, centralized vault, and manage-side observability or reconciliation as marketed. Adjacent products are Primer’s. They are not this page. AI Companion, Global Accounts (collect, convert, and move money packaging), Primer for Partners, industry solution pages, and podcast or research marketing are Primer’s. They are not this page. Companion remains mentionable below as an adjacent module sold on the same dashboard and payments data rails.

Who it’s for

Shapes from homepage, About, Unified payment infrastructure, Checkout, Workflows, Fallbacks, Observability, Reconciliation, Contact, case studies, and docs:

Global merchants and digital commerce teams, which About sells as ambitious merchants optimizing from checkout to payout, and which homepage industry chips name across Travel, Fintech, Platforms, Retail, and Entertainment.
Platforms and marketplace-style sellers, which homepage Platforms chip and case stories (for example Printify) sell as localized checkout and multi-market acceptance without rebuilding processor integrations for every change.
Travel, retail, entertainment, and content businesses expanding methods and processors, which industry solution paths and case studies (GetYourGuide, Conforama, Maisons du Monde, Cleeng, Ferryhopper, and related Primer-named stories) sell as localized payment mix, routing control, and faster market expansion. Attribute named stories as vendor marketing, not independent verification.
Fintechs and crypto-adjacent payment teams optimizing authorization and recovery, which Fintech industry packaging and stories such as Banxa Fallbacks recovery sell as authorization uplift and recoverable declines. Treat recovery dollar quotes as vendor claims, not pricing.

Partner intake is sales-led. Marketing CTAs live at research: Get in touch (sitewide product nav), Book a call with our team (/contact-us), Book a demo (nav and Billable Events page), and contact form framing on Contact (payment expertise; thoughtful pricing and ROI; pricing plans tailored to your business). Docs Get Started assumes Dashboard access: connect a processor, create a Workflow, set up Universal Checkout, explore payments. Docs Authentication: API keys are managed in the Developers area of the Dashboard (https://dashboard.primer.io/developers); sandbox API host https://api.sandbox.primer.io; production https://api.primer.io; X-Api-Key header. Docs Connect a processor: Sandbox includes a Primer test processor automatically; production processors are connected from Dashboard Integrations. Terms: Account creation is required; Fees follow the Order Form; Billable Events may drive Fees; Minimum Commitment may invoice when higher than event Fees. That is not a public self-serve live checkout with a printed buy-rate card that bypasses sales.

It is a fit for a merchant or platform that wants multi-PSP orchestration, checkout, vault, and payment intelligence on Primer’s rails, will complete Book a call / Get in touch / Book a demo and an Order Form, and does not need Primer to acquire, underwrite, or settle as the processor of record.

Accept, Optimize, Manage (core orchestration job). Workflows: no-code drag-and-drop payment logic, conditions, A/B tests across processors or 3DS strategies, and automation (disputes, fraud freezes, Slack notifications as marketed). Checkout: component-based Universal Checkout / Checkout Builder; localize wallets and local methods by country, currency, device; marketing chips on Checkout page include 150+ global integrations, 154 local currencies, 32 languages supported (treat as Primer marketing totals). Centralized vault: store credentials independently of PSPs; tokenize once, use across processors; PCI-DSS Level 1 infrastructure as marketed; CVV recapture via Universal Checkout. Fallbacks: automatically retry failed or soft-declined authorizations on a backup processor; reuse Primer-managed 3DS data so the customer is not challenged again; Fallbacks marketing chips (+38% average payment recovery; recovered payment volume chip; 2X recovery within a week of activation) are Primer claims, not audited results. Network Tokenization and adaptive / Dynamic 3DS sit in Optimize. Observability: unified timelines, dashboards, filters, and A/B measurement across providers. Monitors: near real-time metric alerts, anomaly detection, Slack or email routing via Workflows. Reconciliation: automate settlement matching across methods and processors; FAQ on that page lists current reconciliation processor support as Monext, Klarna, PayPal, Adyen, and Stripe, with expansion marketed; fee and FX insight depends on processor settlement reports as printed. Costs Overview: spot leakage, benchmark providers, reroute to protect margin as marketed. Apps and integrations: marketplace of processors, methods, and fraud providers activated with clicks as marketed. Unified payment infrastructure page: 100+ global integrations; one-click services; authorization and fraud outcome chips are Primer marketing.

Docs path after account: Dashboard Integrations, Workflows, Checkout, Developers API keys, sandbox then production API hosts. Support contacts printed in docs and Terms include support@primer.io, account manager / Solution Engineer / Customer Success Manager paths, and security@primer.io for key compromise. That is sales-led commercial packaging with documented sandbox and API tooling after Account / Order Form access.
Company facts. About timeline: founded in 2020 by ex-PayPal/Braintree employees Gabriel Le Roux and Paul Anthony; seed and Series A in that year as printed; Series B 2021; Fallbacks and Network Tokenization 2023; Reconciliation and APAC depth 2024; AI Companion and Global Accounts 2025; Series C 2026 as printed. Frontmatter founded: 2020 follows Primer’s About timeline (Companies House incorporation for Primer API Limited is 9 December 2019 on the public register; this listing follows the About founded year). Headquarters: London, UK from Privacy registered office (7 Savoy Court, London, United Kingdom, WC2R 0EX). Leadership named on About includes Gabriel Le Roux (Co-founder and CEO), Pierre-Edouard Jumel (CFO), Mikael Minvielle (COO), Alex Mallet (CTO), and VPs across People, Marketing, Product, Merchant Experience, and Global Sales. About outcome tiles animate to blank or zero in static fetch; homepage chips ($ Billions processed every month; 95%+ of customer payment volume; 99.99% uptime) are Primer marketing, not independently audited figures. Banxa quote on homepage (US$7 million recovered using Fallbacks) is a customer story claim, not a price list.
License and security posture (as printed). Terms External Services and Customer Transactions: merchant keeps a direct contract with processors; Primer is not responsible for the chosen payment processor or for goods sold. PCI-DSS certification maintained by Primer; merchant still verifies third-party processor PCI posture. Homepage and Security: PCI-1, GDPR, SOC2 Type-2; encryption in transit and at rest; least-privilege access; AWS hosting; regular penetration tests as marketed. Privacy: Primer API Limited; merchant is controller for end-customer payment data when Primer acts as processor under UK/EU GDPR language; Companion model-training notes appear in Privacy and Terms. Partner and PSP names on Apps and integrations, Reconciliation FAQ, and docs (examples include Adyen, Stripe, PayPal, Klarna, Monext, Braintree, and many others) are infrastructure Primer connects to. They are not this page’s product.
Adjacent modules (wall-off). This page is Primer payments orchestration / unified payments intelligence (Accept, Optimize routing and recovery, Manage observability and reconciliation). Adjacent products are Primer’s. They are not this page. AI Companion (/ai-companion) is an adjacent dashboard AI teammate mentionable here because it reads the same payments data and Fallbacks or auth metrics without replacing the orchestration listing. Global Accounts (collect, convert, move money), Primer for Partners, industry landing pages, The Primer Showcase, and Payments Unfiltered podcast sit next to the core job.

Honest verdict

Primer is the listing to read when the job is unified payments orchestration and intelligence for a merchant or platform: connect many processors through one layer, build no-code Workflows, recover soft declines with Fallbacks, run Universal Checkout and a centralized vault, and observe or reconcile across providers. Primer is not the processor of record, not a bank, and not the PayFac that underwrites and settles merchants. Acquiring and settlement stay with the merchant’s chosen processors under direct External Services contracts. Primer supplies the orchestration, checkout, vault, routing, recovery, and manage-side visibility rails.

What it is not: a processor of record, a bank charter, a lender, or a published public buy-rate card. /pricing was not live at research. Commercial terms go through Order Form and sales (Get in touch, Book a call, Book a demo). Billable Events define how volume and recovery may be measured; they are not a self-serve price list. Homepage volume and recovery chips, and customer Fallbacks recovery quotes, are Primer marketing. If you need the vendor itself to acquire and settle as processor of record, stop. If the job is multi-PSP orchestration plus payment intelligence without giving up processor choice, start here.
