Flatpay

Flatpay is a fast-growing Danish fintech company that is reshaping how small and medium-sized businesses across Europe accept card payments. Founded in 2022 and headquartered in Copenhagen, Denmark, Flatpay has quickly gained traction by offering a radically simple proposition: a flat transaction rate of 0.99% on all card payments, no monthly fees, no binding contracts, and no hidden costs. In an industry historically plagued by opaque pricing structures, complex fee schedules, and long-term lock-in agreements, Flatpay stands out as a breath of fresh air for business owners who want straightforward, predictable payment processing without the headaches.

A Disruptive Approach to Card Payments

The traditional payment processing industry has long been a source of frustration for small business owners. Legacy providers like Nets, Worldline, and other acquirers typically charge a complex mix of interchange fees, scheme fees, processing fees, monthly minimums, terminal rental charges, and various hidden surcharges that make it nearly impossible for merchants to predict their actual costs. Many providers also lock businesses into contracts lasting 12 to 36 months, with hefty early termination fees if merchants want to switch.

Flatpay was built specifically to solve these pain points. The company's founders recognized that small business owners do not want to become experts in payment processing fee structures. They want to accept card payments, know exactly what they will pay, and get on with running their business. Flatpay delivers on this promise with a single, fixed rate of 0.99% per transaction regardless of the card type, whether it is a Visa, Mastercard, Dankort, or any other supported card brand. There are no additional fees for contactless payments, chip-and-PIN transactions, or different card categories. The rate is the rate, full stop.

Fixed-Rate Pricing Model

Flatpay's 0.99% fixed rate is one of the most competitive and transparent pricing models available in the European POS market. Unlike interchange-plus pricing models used by many processors, which can result in wildly varying effective rates depending on the card type and issuing bank, Flatpay's flat rate means merchants always know exactly what they will pay. For a business processing 10,000 euros in card payments per month, the cost is a straightforward 99 euros. There are no surprises on the monthly statement, no unexplained line items, and no gradual fee creep over time.

This pricing transparency is particularly valuable for small businesses operating on thin margins, such as cafes, bakeries, hair salons, and independent retailers. These businesses need to forecast their costs accurately, and Flatpay's fixed-rate model makes that possible. The 0.99% rate applies to all transaction types processed through Flatpay terminals, including contactless tap payments, chip-and-PIN transactions, and mobile wallet payments from Apple Pay, Google Pay, and Samsung Pay.

No Binding Contracts

One of Flatpay's most appealing features for business owners is the complete absence of binding contracts. Traditional payment processors often require merchants to sign agreements lasting one to three years, with automatic renewal clauses and substantial early termination penalties. This creates a situation where businesses feel trapped, unable to switch to a better deal even when one becomes available.

Flatpay operates on a completely different philosophy. Merchants can start using the service and stop at any time without penalties. There is no minimum contract duration, no notice period required for cancellation, and no exit fees. This approach demonstrates Flatpay's confidence in its own value proposition. Rather than relying on contractual lock-in to retain customers, the company earns loyalty by consistently delivering a better deal and better service than the alternatives. If a merchant is unhappy, they can leave immediately without financial consequences.

Terminal Hardware Options

Flatpay offers a range of modern payment terminal hardware designed to suit different business environments. The company's countertop terminals are ideal for fixed retail locations, restaurants, and service businesses where payments are typically processed at a checkout counter or reception desk. These terminals feature large, easy-to-read screens, fast processing times, and support for all major payment methods including contactless NFC payments, chip-and-PIN cards, and magnetic stripe cards.

For businesses that need mobility, Flatpay also provides portable wireless terminals that connect via WiFi or mobile data. These are perfect for restaurants where staff take payments tableside, market stalls, food trucks, delivery services, and any business where the point of sale moves around. The terminals are compact, lightweight, and have long battery life to last through a full business day. All Flatpay terminals are designed with simplicity in mind, featuring intuitive interfaces that require minimal training for staff to operate confidently.

Flatpay provides the terminal hardware as part of its service, which means businesses do not need to make a large upfront investment in equipment. The terminals are modern, well-built devices that support the latest payment technologies and security standards. When upgrades become available, Flatpay ensures its merchants have access to current hardware without additional charges.

Setup and Onboarding Process

Getting started with Flatpay is designed to be as fast and frictionless as possible. The company has streamlined its onboarding process to get businesses accepting card payments within days rather than the weeks or months that traditional payment processors often require. Merchants can sign up online, provide the necessary business verification documents, and receive their terminal hardware quickly. The setup process for the terminals themselves is straightforward, typically requiring only a power connection and a WiFi or mobile data signal.

Flatpay provides dedicated support during the onboarding phase to ensure a smooth transition, whether a business is accepting card payments for the first time or switching from another provider. The company's customer service team is known for being responsive and helpful, guiding merchants through every step from application to first transaction. This hands-on approach to onboarding sets Flatpay apart from larger, more impersonal payment processors where small businesses can feel like just another account number.

Target Market and European Expansion

Flatpay's primary target market is small to medium-sized businesses across Europe. The company initially launched in Denmark, where it quickly gained significant market share among local businesses frustrated with the complexity and cost of traditional payment processing. The Danish market proved to be an ideal testing ground, as Denmark is one of the most cashless societies in Europe, with the vast majority of consumer transactions conducted via card or mobile payments.

Building on its success in Denmark, Flatpay has been expanding across Europe, bringing its simple pricing model and no-contract philosophy to new markets. The company's expansion strategy focuses on countries where small businesses face similar challenges with opaque payment processing fees and restrictive contracts. As Flatpay enters each new market, it adapts its offering to comply with local regulations and support local payment methods while maintaining its core value proposition of simplicity and transparency.

The European POS and payment processing market is substantial, with millions of small businesses that could benefit from Flatpay's approach. The company has attracted significant venture capital funding to fuel its expansion, with investors recognizing the large market opportunity and the strength of Flatpay's disruptive model. The company's rapid growth in its initial markets suggests strong product-market fit and indicates significant potential for continued expansion across the continent.

GDPR Compliance and Data Security

As a Danish company operating within the European Union, Flatpay is fully compliant with GDPR and European data protection regulations. All transaction data is processed and stored within the EU, ensuring that merchants' and their customers' financial data never leaves European jurisdiction. This is an important consideration for businesses that want to ensure their payment processing complies with European privacy standards, particularly in an era of increasing regulatory scrutiny around data handling.

Flatpay's payment terminals and processing infrastructure comply with PCI DSS (Payment Card Industry Data Security Standard) requirements, which is the global security standard for organizations that handle card payments. All card data is encrypted end-to-end, from the moment a card is tapped or inserted at the terminal through to the transaction being processed and settled. This means that sensitive card information is never exposed in plaintext at any point during the payment process.

The company also implements robust security measures at the organizational level, including access controls, regular security audits, and employee training on data protection best practices. For merchants, this means they can accept card payments with confidence that both their business data and their customers' payment information are protected to the highest European standards.

Integration Capabilities

While Flatpay's core strength is its simplicity, the company also recognizes that many businesses need their payment processing to integrate with other systems. Flatpay offers integration capabilities with popular point-of-sale systems, accounting software, and business management tools used by European small businesses. These integrations allow transaction data to flow automatically into a business's existing workflows, reducing manual data entry and the risk of errors.

Flatpay provides a merchant dashboard that gives business owners real-time visibility into their transaction history, sales patterns, and payment volumes. This dashboard is accessible via web browser and mobile devices, allowing merchants to monitor their business performance from anywhere. The reporting features help businesses understand their sales trends, identify peak trading periods, and make data-driven decisions about their operations.

Pricing in Detail

Flatpay's pricing model is perhaps the simplest in the European payment processing industry. The core offering consists of a flat 0.99% fee per transaction with no monthly subscription fees, no terminal rental charges, no minimum transaction requirements, and no setup fees. This all-inclusive approach means the total cost of payment processing is entirely predictable and directly proportional to sales volume.

For businesses comparing Flatpay to traditional payment processors, the savings can be substantial. Many legacy providers charge effective rates of 1.5% to 2.5% when all fees are combined, plus monthly charges of 20 to 50 euros for terminal rental and account maintenance. A business processing 15,000 euros per month could easily save 100 euros or more by switching to Flatpay, savings that go directly to the bottom line. Over the course of a year, these savings add up to over 1,000 euros, which is meaningful for any small business.

Flatpay settles funds to merchants' bank accounts quickly, typically within one to two business days. Fast settlement is important for small businesses that need predictable cash flow to manage their operations effectively. There are no additional charges for settlement, and merchants can track their payouts through the Flatpay dashboard.

Flatpay vs Competitors

When compared to US-based alternatives like Square, Flatpay offers several advantages for European businesses. Square charges higher transaction fees in most European markets and requires businesses to use Square's own ecosystem of software and hardware. Flatpay focuses specifically on doing one thing exceptionally well: processing card payments at the lowest possible fixed rate. For businesses that already have POS software or simply need a reliable card terminal, Flatpay's focused approach is often a better fit than an all-in-one system they may not fully utilize.

Compared to other European payment processors like SumUp, Flatpay's 0.99% rate is highly competitive. SumUp typically charges 1.69% per transaction in most European markets, which means Flatpay can save businesses a significant amount on processing fees, particularly those with higher transaction volumes. However, SumUp offers a broader range of additional software features, so the best choice depends on whether a business prioritizes the lowest possible transaction fees or a more comprehensive software suite.

Against traditional acquirers and bank-based payment processors, Flatpay's advantages are even more pronounced. The combination of transparent pricing, no binding contracts, modern hardware, fast onboarding, and responsive customer support represents a fundamentally different and better experience for small business owners. Traditional processors may offer lower headline rates for very large businesses processing hundreds of thousands of euros per month, but for the vast majority of small and medium-sized businesses, Flatpay's offering is hard to beat.

Who Should Use Flatpay

Flatpay is ideal for small to medium-sized businesses across Europe that want a simple, transparent, and affordable way to accept card payments. Whether you run a cafe, restaurant, retail shop, salon, market stall, or any other business that accepts in-person payments, Flatpay's combination of low fixed rates, no contracts, and easy setup makes it an excellent choice. Businesses that are currently locked into expensive contracts with traditional processors should consider Flatpay as soon as their current agreement allows, while new businesses can start with Flatpay from day one and avoid the complexities of traditional payment processing entirely. With its Danish roots, GDPR compliance, and commitment to simplicity, Flatpay represents the best of European fintech innovation applied to a problem that has frustrated small business owners for decades.
