Sacra estimates that SumUp generated $600 million in annual recurring revenue (ARR) in 2025. The company has maintained positive EBITDA since December 2022 and processes over 1 billion transactions annually across its platform.

SumUp's revenue comes primarily from payment processing fees, with merchants paying between 1.69% for in-person transactions in the UK and 2.5% for remote payments through payment links and online stores. The company also generates revenue from hardware sales, including card readers and POS systems, and subscription fees for advanced software features and financial services such as business accounts and lending.

The platform serves over 4 million small and medium businesses across 36 countries, generating an average revenue per customer of approximately $188. Revenue mix is roughly 45% card readers and hardware, 30% payment processing, 15% software subscriptions, and 10% financial services, including business banking and merchant cash advances.

SumUp completed a $1.62 billion (€1.5 billion) private credit financing in May 2024 led by Goldman Sachs. Key participants included Sixth Street Growth, Bain Capital Tech Opportunities, BlackRock, AllianceBernstein, and Apollo Global Management.

The company previously raised $308 million (€285 million) in December 2023 and $637 million (€590 million) in June 2022 at an $9.18 billion (€8.5 billion) valuation.

SumUp has raised approximately $3.56 billion (€3.3 billion) in total funding across equity and debt financing rounds since its founding in 2012.

SumUp started as a mobile card reader company and now offers a suite for small businesses to accept payments, manage money, and run operations.

The core hardware lineup includes the Air and Plus Bluetooth card readers that pair with smartphones, the Solo touchscreen terminal with 4G connectivity, and POS systems ranging from the POS Lite bundle to POS Pro setups with inventory management and multi-location reporting. The company also offers Tap to Pay functionality that turns any NFC-enabled iPhone or Android device into a payment terminal without additional hardware.

For remote payments, SumUp provides payment links shareable via SMS or social media, QR codes for contactless ordering, online store builders that sync with in-person inventory, and invoice generation with embedded payment buttons. All remote payment options use hosted checkout pages to simplify setup for merchants.

The financial services layer includes business banking accounts with IBANs, Mastercard debit cards, instant transfers, and multi-currency sub-accounts. SumUp also offers merchant cash advances up to €20,000 based on payment processing history, plus tools for expense management and financial reporting.

Recent product additions include self-service kiosks for restaurants and retail, a handheld terminal combining reader and printer functionality, and SumUp Pay consumer wallet with cashback and peer-to-peer payments in select markets.

SumUp uses a B2B fintech model and monetizes through payment processing fees, hardware sales, software subscriptions, and financial services revenue. The company targets micro and small businesses that need payment acceptance and business management tools.

Payment processing is the primary revenue source, with merchants charged between 1.69% and 2.9% per transaction depending on the payment method and market. Revenue is usage-based and tied to merchant transaction volume.

Hardware provides an upfront revenue stream and a customer acquisition channel, with card readers and POS systems sold at set price points. The company then captures ongoing processing revenue and cross-sells software and financial services.

SumUp's business account and financial services add recurring revenue. Merchants who use SumUp for banking, lending, and money management consolidate more activity on the platform.

The model benefits from network effects as more merchants drive payment volume, enabling better rates from card networks and banks. Geographic expansion leverages the same core platform across markets, creating operational scale while local partnerships handle regulatory requirements and market-specific features.

Square offers an ecosystem of hardware, software, and financial services for small businesses. Square charges similar processing fees around 1.75% and provides software integration including payroll, marketing, and analytics. Block's Cash App now enables Tap to Pay on iPhone for over 1 million sellers, competing with SumUp's mobile payment acceptance.

PayPal Zettle integrates with PayPal's 400 million consumer wallet network and has gained NFC access on iPhone across Germany and Nordic markets. Zettle offers built-in PayPal and Venmo checkout options but typically charges processing fees between 1.75% and 2.5%.

Stripe Terminal focuses on developers and larger merchants with omnichannel payment acceptance, recently expanding to Japan and partnering with Verifone for enterprise-grade hardware integration. Stripe's developer-first approach and enterprise focus create less direct overlap with SumUp's small business positioning.

European competitors include myPOS, Viva Wallet, and Revolut Business, each offering payment processing and business banking services. These players often have stronger local market knowledge and regulatory relationships but lack SumUp's geographic scale across 36 countries.

Revolut Business has expanded into business banking and lending, creating direct competition for SumUp's financial services offerings. However, Revolut's consumer-first brand and pricing model differ from SumUp's merchant-focused approach.

Traditional acquirers like Worldpay and payment processors are adding small business tools, but typically lack the integrated hardware and software experience that SumUp offers.

Apple's mandated NFC opening across 25+ European countries has eroded SumUp's historical hardware moat, allowing competitors like Stripe, Revolut, and PayPal to offer Tap to Pay functionality on iPhones. This commoditizes payment acceptance technology and shifts competition toward software, services, and pricing.

SoftPOS technology more broadly enables any smartphone to accept contactless payments, reducing the differentiation of dedicated card readers and POS hardware that helped establish SumUp's market position.

SumUp's business banking platform now serves over 1 million merchants and provides a base for additional financial services including lending, insurance, and treasury management. The company offers merchant cash advances up to €20,000 and has secured credit facilities to scale lending operations.

SumUp Pay in Ireland adds a virtual Mastercard, cashback rewards, and peer-to-peer functionality, creating two-sided network effects between merchants and consumers. This enables SumUp to capture interchange revenue and deposit float and to increase customer retention.

Business expense management, multi-currency accounts, and corporate card programs are extensions that can increase revenue per merchant and create switching costs through deeper financial integration.

Hospitality and retail partnerships with companies like FreedomPay enable SumUp to serve larger venues including hotels, multi-location retailers, and restaurant chains that were previously outside its small business focus. These partnerships provide enterprise payment rails and same-day settlement capabilities.

Self-service kiosks for quick-service restaurants and retail venues can increase average transaction values by up to 30% and generate higher-margin software and hardware revenue. The kiosk product creates opportunities for vertical-specific features and pricing.

Industry-specific tools for sectors like healthcare, professional services, and e-commerce could use SumUp's core payment and banking infrastructure while commanding premium pricing for specialized functionality.

SumUp's re-entry into the US market through the Fivestars acquisition provides access to the world's largest small business payments market. The company is investing in US expansion with bundled POS, loyalty, and kiosk offerings designed to compete directly with Square's core market.

Recent expansion into Australia as the 36th market marks continued international scaling, with additional launches planned across Asia-Pacific and Latin America. Each new market uses the existing technology platform while adding local payment methods and regulatory compliance.

Emerging markets represent long-term opportunities as small businesses digitize payment acceptance and financial services adoption increases in regions with large unbanked populations.

Commoditization pressure: Apple's mandated NFC opening and broader SoftPOS adoption eliminate SumUp's hardware differentiation, shifting competition to software features and pricing, where larger players such as Square and PayPal have deeper resources and established ecosystems. This could compress processing margins and reduce customer acquisition advantages.

Regulatory fragmentation: Operating across 36 countries exposes SumUp to diverse and changing financial regulations, data privacy requirements, and payment network rules that could increase compliance costs or restrict product offerings. Brexit-related changes and evolving EU financial services regulations add complexity to cross-border operations.

Scale disadvantage: Competitors such as Square benefit from larger merchant bases that provide better negotiating power with card networks and banks, potentially enabling lower processing costs and more competitive pricing. SumUp's smaller scale in key markets like the US could limit its ability to match pricing from established players while maintaining profitability.
