Checkout.com has gone from a bootstrapped Singapore payments startup to a $12 billion fintech processing $300 billion a year for the likes of Uber, Spotify, and eBay and it did it without ever selling a single flashy consumer product. So how does Checkout.com make money, exactly? The short answer is transaction fees, layered with FX margin and fraud tooling on top.
The longer answer and the more interesting one is a business model built on enterprise trust rather than volume of small merchants, backed by a valuation that's swung from $40 billion to under $10 billion and back again in the space of three years. Here's what Checkout.com is, how its business model actually works, and where the money comes from.
What Is Checkout.com?
Checkout.com is a London-headquartered payments infrastructure company that lets enterprise merchants accept, process, and optimize online payments through a single unified API. Legally incorporated as Checkout Ltd, it operates as a payment gateway, acquirer, and processor rolled into one, across sectors from e-commerce to media.
It's a founder's story before it's a fintech one. Guillaume Pousaz rebranded his Singapore-based Opus Payments as Checkout.com in 2012, then bootstrapped it for seven years with no outside capital, just discipline: grow revenue roughly 50% a year and let profitability do the talking. Unusual for fintech, where most companies raise early and scale on someone else's money.
The numbers now show what that patience bought. The Checkout.com business model has scaled to more than $300 billion in total payment volume in 2025 a 64% jump year-on-year with net revenue growing above 30% for the second year running and full-year EBITDA profitability at margins above 10%. Over 1,000 enterprise merchants now run on the platform, including Uber, eBay, Spotify, and Pinterest, with 63 of them each processing more than $1 billion a year up from 39, a sign the enterprise base is growing up, not just growing.
The Global Payments Problem It Solves
Checkout.com exists to remove the friction that builds up when a business tries to accept payments across borders. Historically, that meant stitching together a payment gateway, a processor, an acquirer, multiple banking relationships, and separate fraud tooling, each one a different vendor, a different point of failure. Checkout.com bundles all of it into one integration, so a merchant deals with a single provider instead of chasing down five.
That matters more the bigger a business gets. A fast-scaling e-commerce brand selling into 40-plus countries needs more than card acceptance; it needs high authorisation rates, local payment methods that convert, and fraud detection sharp enough to catch bad actors without blocking good customers. Miss any one of those, and the cost shows up not on an invoice, but as a customer declined at checkout who never comes back.
Checkout.com is authorised by the FCA as an electronic-money institution and holds direct principal membership with the major card schemes, letting it sit closer to the money than a simple payments reseller would. It isn't a bank that customer funds are safeguarded under EMI rules, not FSCS-insured deposits but that regulatory footing is what makes the "one integration, global reach" pitch credible rather than marketing gloss. It's also what lets Checkout.com operate across 45-plus countries with domestic acquiring, rather than routing every transaction through a single home market.
How It Makes Money: Transaction Fees
Checkout.com makes money mainly by charging merchants a Merchant Service Charge on every transaction it processes a blend of a percentage of the payment plus a small fixed fee, built on what's known as an Interchange Plus Plus (IC++) structure.
Under IC++, the bill is unbundled into three visible pieces: the interchange fee set by the card network, the scheme fee charged by Visa or Mastercard directly, and Checkout.com's own negotiated markup sitting on top. That third piece of the markup is where Checkout.com actually earns its keep; the first two are simply passed through to the issuing bank and the card schemes.
For well-qualified, high-volume merchants, that markup is estimated by industry reviewers at roughly 0.1%–0.4% plus a small fixed fee per transaction though Checkout.com doesn't publish a fixed rate card, so any real quote comes down to volume, risk profile, and payment mix agreed directly with sales. That opacity is deliberate: it's a trade-off enterprise merchants tend to accept in exchange for a rate genuinely tailored to their volume, rather than a one-size-fits-all headline number that looks good in a pitch deck and worse on the actual invoice.
The fee itself isn't the whole picture, though. Foreign exchange conversion adds a margin whenever a customer pays in one currency and the merchant settles in another. Fraud tools, built on machine-learning models trained across the platform's transaction data, form a paid layer on top of the base processing fee, and increasingly a differentiator in their own right; a merchant losing money to false declines has just as real a problem as one losing money to fraud. It's a structure common across the payments industry, but the Checkout.com business model leans harder on enterprise volume and value-added services than on raw transaction count, since there's no self-serve SMB tier diluting the mix.
Funding and Valuation History
Checkout.com has raised $1.83 billion across four funding rounds since 2019, and its valuation has swung more dramatically than almost any other European fintech's. The company took no outside capital until its Series A in May 2019 $230 million, one of the largest early-stage fintech rounds Europe had seen at the time. A Series B followed in 2020 at $150 million, pushing the valuation to $5.5 billion, then a Series C in January 2021 brought in $450 million at a $15 billion valuation. The peak came with the Series D in January 2022: $1 billion raised at a $40 billion valuation, making Checkout.com briefly the second most valuable private company in Europe after Klarna.
What follows is a story about the wider fintech correction, not about Checkout.com's own trading. The company marked its internal valuation down to $11 billion by late 2022, then to $9.35 billion in 2023, as the market-wide tech valuation reset hit private fintechs across the board Checkout.com wasn't an outlier here; Stripe's own valuation dropped from $95 billion to $50 billion over roughly the same period.
It's since clawed back: a September 2025 employee share buyback, based on an independent 409A assessment rather than new outside investment, set the valuation at $12 billion, a near-30% recovery from the 2023 low, though still well short of the 2022 peak.
Checkout.com vs Stripe vs Adyen
Checkout.com, Stripe, and Adyen compete at the same enterprise level but suit genuinely different businesses. Stripe wins on speed and developer experience, the fastest integration times, the widest SDK ecosystem and is the natural pick for startups and SaaS businesses that want to go live fast without a lengthy sales cycle. Adyen leads on authorisation rates and direct acquiring relationships across 30-plus countries, making it the choice for large omnichannel retailers running online and in-store from one stack, complete with its own point-of-sale hardware. Checkout.com sits between the two: strongest for fast-growing, international e-commerce brands and marketplaces that lean heavily on local payment methods, particularly across Europe and the Middle East.
Pricing transparency is where the Checkout.com business model diverges most sharply from its rivals. Stripe publishes its rate card outright. Adyen publishes an indicative IC++ structure but gathers the finer detail. Checkout.com keeps its rates behind a sales conversation entirely a trade-off that suits large merchants able to negotiate hard on volume, but one that makes it a poor fit for anyone wanting a quick, self-serve quote before they've even spoken to anyone. Beyond these two, PayPal and Worldpay round out the competitive set most often cited alongside Checkout.com, though neither shares its enterprise-only, API-first positioning quite as closely.
FAQs
1. How does Checkout.com make money?Checkout.com makes money primarily through a Merchant Service Charge, a blended transaction fee combining a percentage of volume with a fixed per-transaction cost, built on an Interchange Plus Plus pricing structure. On top of that base fee, it earns margin from foreign exchange conversion and from value-added services like machine-learning-powered fraud prevention tools.
2. What is Checkout.com's valuation?Checkout.com's valuation currently stands at $12 billion, set during a September 2025 employee share buyback. That's down from its $40 billion peak in the January 2022 Series D round, having dipped to $9.35 billion in 2023 before recovering.
3. Who are Checkout.com's competitors?Checkout.com's closest competitors are Stripe and Adyen, the two other payment platforms most frequently compared to it at enterprise scale. PayPal and Worldpay also feature regularly in broader competitor comparisons, though with somewhat different positioning.

The Bottom Line
The Checkout.com business model is straightforward in principle and layered in practice: charge merchants a blended transaction fee, then stack fraud tools and FX margin on top, and let enterprise volume do the heavy lifting. What's harder to ignore is the valuation arc sitting underneath it a $2 billion Series A company that hit $40 billion in three years, got marked down to under $10 billion in the fintech correction, and has spent the past two years quietly rebuilding towards $12 billion on the back of actual profitability rather than fresh capital.
So how does Checkout.com make money, in the end? Through fees, yes but the more instructive story is the one underneath: growth that outran its valuation, followed by a valuation that's now trying to catch back up to the business.
