In European payments, scale has traditionally been associated with sophisticated technology, broad merchant coverage, and increasingly complex pricing structures. Danish fintech Flatpay is pursuing a different proposition: simplify the merchant experience, standardize pricing, and build a high-volume payments business around small and mid-sized enterprises (SMEs).
Founded in Copenhagen in 2022, Flatpay provides card-payment terminals, point-of-sale (POS) systems, and online payment services. Its core proposition is deliberately straightforward: merchants pay a flat transaction rate rather than navigating a complicated schedule of card-type, subscription, setup, and transaction fees. The company has subsequently expanded beyond Denmark into Finland, Germany, Italy, France, the Netherlands, and the United Kingdom.
For finance professionals, however, Flatpay is more interesting as a business-model experiment than simply as another payment processor. Its growth illustrates how a fintech can use pricing transparency, vertical integration, and a highly targeted sales model to compete in a market dominated by much larger incumbents.
The business model: monetizing payment volume
At its simplest,** Flatpay**’s business model is transaction-based. Instead of relying primarily on recurring software subscriptions, the company earns revenue when merchants process payments through its infrastructure.
Its current pricing illustrates the model. Flatpay advertises a 0.99% transaction rate for its payment-terminal offering in several markets, with no subscription or fixed transaction fee. Its POS products can carry different rates and upfront hardware costs, while online payments have separate pricing for different card categories and payment methods.
The economic logic is straightforward:
Merchant payment volume × Flatpay’s effective take rate = transaction revenue
This creates an important alignment between Flatpay and its customers. If merchants process more card payments, Flatpay’s revenue increases. The challenge is that the headline transaction rate is not the same as economic margin: Flatpay must absorb or pass through the costs associated with payment networks, acquiring, fraud, hardware, customer support, sales, and other operating expenses.
Consequently, the key financial question is not simply how much transaction volume Flatpay processes, but how much contribution margin it generates per merchant and how quickly that margin scales relative to customer-acquisition costs.
Why the flat-rate proposition matters
Payment processing is inherently difficult for merchants to understand. The economics can involve interchange, scheme fees, acquiring fees, terminal costs, software subscriptions, minimum charges and different rates for different card types.
Flatpay attempts to remove much of that complexity.
Its proposition is effectively a shift from price optimization for the payment provider toward predictability for the merchant. Flat pricing can make payment costs easier to forecast and can reduce the perceived friction associated with switching providers.
That simplicity is particularly valuable for smaller businesses, where owners may not have dedicated payments or treasury teams.Flatpay therefore competes not only on price but also on financial transparency and reduced operational complexity.
The company also emphasizes daily payouts and a merchant portal that provides transaction and sales information, extending the proposition beyond simple payment acceptance into cash-flow visibility and business management.
A deliberately focused customer segment
Flatpay’s early strategy was not to compete for every merchant.
In 2024, the company told TechCrunch that it targeted merchants processing more than €100,000 annually and generally avoided multi-location chains and franchises. At that point, Flatpay had approximately 7,000 customers across Denmark, Finland and Germany.
This focus is important from a unit-economics perspective.
A payment processor incurs costs to acquire and onboard every merchant. Sales representatives, hardware deployment, installation, customer support and compliance processes can make very small accounts unattractive. By focusing on merchants with meaningful transaction volume,Flatpaycan potentially generate enough recurring payment revenue to justify those acquisition and servicing costs.
In other words, the company is not simply selling a cheaper card terminal. It is attempting to construct a merchant-level economic model in which higher payment volume supports the cost of acquiring and servicing the customer.
The unusual role of sales in a fintech model
One of the more distinctive elements of Flatpay’s strategy is that its go-to-market model has historically relied heavily on in-person sales.
That may appear counterintuitive for a technology company. Yet it reflects an important characteristic of SME payments: changing a payment provider is operationally consequential. Merchants need to understand pricing, hardware, installation, settlement and integration before they are comfortable switching.
Flatpay therefore combines technology with what its investors describe as “old-school people-led sales.” Dawn Capital says the company’s growth has been driven by a combination of customer-focused products, people-led sales and technology.
For investors, this creates an interesting trade-off.
A direct sales model can increase customer-acquisition costs and limit scalability compared with a purely digital acquisition funnel. But if it materially improves conversion rates, merchant retention and payment volume, the higher upfront cost can produce attractive lifetime economics.
The critical metric is therefore not sales efficiency in isolation, but customer lifetime value relative to customer-acquisition cost (LTV/CAC).
Growth before profitability
Flatpay’s financial history also demonstrates the cost of aggressive expansion.
According to the company’s 2024 Danish accounts, Flatpay ended 2024 with approximately 17,000 customers, representing 300% year-on-year growth. The company generated DKK 12 million in gross profit, compared with a DKK 3 million gross loss in the previous year. However, its net loss increased to DKK 151 million from DKK 52 million in 2023 as the company invested heavily in expansion.
This is a classic growth-fintech profile: gross economics improving while bottom-line profitability remains negative because operating expenses are being deployed ahead of revenue maturity.
For an investor, the distinction matters.
A growing net loss is not necessarily problematic if each new cohort of merchants produces attractive contribution economics and the company’s fixed-cost base can eventually be leveraged. Conversely, rapid revenue growth accompanied by persistently weak unit economics would suggest that scale is being purchased rather than created.
Flatpay’s investment case therefore depends heavily on whether operating leverage emerges as the merchant base expands.
From startup to European fintech unicorn
The company’s funding trajectory reflects investor confidence in that model.
Flatpay raised €45 million in a Series B led by Dawn Capital in April 2024, bringing its valuation to more than $100 million at the time.
By November 2025, Flatpay had raised a further €145 million at a valuation of approximately €1.5 billion, according to Dawn Capital. The investor also reported that the company had exceeded €100 million in annual recurring revenue and had expanded across several European markets.
TechCrunch reported in November 2025 that** Flatpay** had reached approximately 60,000 customers, up from 7,000 in April 2024.
That trajectory illustrates the central investment thesis: the company is attempting to turn a relatively simple merchant proposition into a highly scalable European payments platform.
Flatpay’s position within fintech
Flatpay sits at the intersection of several fintech categories.
First, it is a payments company, because its primary economic activity is processing merchant transactions.
Second, it is increasingly a merchant software company, because its POS products combine payment acceptance with sales, order, reporting and operational functionality.
Third, it has characteristics of a financial infrastructure platform, because recurring payment flows create a foundation on which additional merchant financial services could potentially be built.
This last point is strategically important. Payment processing can provide frequent interaction with a merchant’s financial activity. A provider that understands transaction volume, cash flows and business performance may eventually have opportunities to offer adjacent products.
However, Flatpay’s current proposition should not be confused with a bank or lending fintech. Its core business remains merchant payments and POS infrastructure.
The competitive challenge
Flatpay operates in a highly competitive market alongside established payment companies and fintech platforms such as Adyen, Stripe, PayPal and SumUp.
The company’s competitive advantage therefore cannot simply be “payment processing.” Large incumbents already possess enormous scale and sophisticated infrastructure.
Flatpay’s differentiation is instead based on simplicity, targeted distribution and merchant service.
Its strategy effectively asks whether an SME would prefer a highly optimized but complicated payment proposition or a straightforward one with predictable pricing and hands-on support.
That positioning can be powerful, but it also creates several risks.
1. Margin pressure
A flat rate simplifies pricing for the merchant but does not eliminate the underlying cost structure of card payments. If the cost of processing particular transactions rises, Flatpay may have less pricing flexibility than a provider using more granular pricing.
2. Customer-acquisition costs
A people-led sales strategy can be expensive. Maintaining attractive LTV/CAC economics will be crucial as the company expands into increasingly competitive markets.
3. Geographic complexity
European payments are fragmented by national payment methods, regulations, consumer behavior and incumbent relationships. Expanding from Denmark into multiple European markets therefore introduces operational complexity even when the underlying product is standardized.
4. Incumbent response
Large payment providers can potentially replicate simple pricing structures or compete aggressively for high-value SME customers. Flatpay must therefore continue improving its product and distribution advantages.
What finance professionals should watch
For analysts and investors evaluating Flatpay, headline customer growth is only one part of the story. Several operating metrics are arguably more revealing.
Payment volume per merchant indicates whether Flatpay is attracting increasingly valuable customers.
Effective take rate shows how much revenue the company generates relative to processed volume.
Gross margin and contribution margin reveal whether scale is translating into better economics.
CAC payback period indicates how quickly sales and onboarding costs are recovered.
Merchant retention determines the durability of recurring transaction revenue.
Operating leverage determines whether the company can convert rapid top-line growth into sustainable profitability.
Finally, cash burn relative to growth is critical. A payments company can grow extremely quickly while consuming significant capital because hardware, sales infrastructure and international expansion require upfront investment.
Conclusion
Flatpay represents a broader shift occurring in European fintech: innovation does not always require a radically new financial product. Sometimes it comes from redesigning the economics and customer experience around an existing financial service.
The company’s proposition is deceptively simple. Give SMEs a payment terminal and POS system, charge a transparent transaction rate, provide fast settlement and human support, and build revenue as merchants process more payments.
The financial challenge is considerably more complex.
Flatpay must demonstrate that its simplified pricing can coexist with attractive payment-processing margins, that its sales-heavy acquisition model can generate strong customer lifetime value, and that international expansion can eventually produce operating leverage.
Its rapid growth — from 17,000 customers at the end of 2024 to roughly 60,000 reported in late 2025 — suggests substantial market demand for the proposition.
For finance professionals, Flatpay is therefore worth watching not merely as a fast-growing fintech, but as a case study in how pricing transparency, distribution strategy and payment-volume economics can be combined to challenge established financial infrastructure providers.
