Frequently Asked Questions

Yes, Flatpay is fully GDPR compliant. As a Danish company headquartered in Copenhagen, it operates under European data protection laws. All transaction data is processed and stored within the EU, and Flatpay's payment infrastructure complies with PCI DSS security standards. Card data is encrypted end-to-end throughout the entire payment process.

Flatpay is headquartered in Copenhagen, Denmark. The company was founded in 2022 and has been expanding rapidly across European markets. As a Danish company, Flatpay operates under EU jurisdiction, ensuring your data is protected by European privacy laws and not subject to US legislation like the CLOUD Act.

Flatpay charges a flat rate of 0.99% per transaction with no monthly fees, no terminal rental charges, no setup fees, and no minimum transaction requirements. This all-inclusive rate applies to all card types including Visa, Mastercard, and contactless payments via Apple Pay, Google Pay, and Samsung Pay.

Flatpay is a European alternative to Square, Toast POS, and other US-based payment processing solutions. It also competes with traditional European payment processors and acquirers that charge complex, opaque fee structures. Flatpay offers lower effective rates than most competitors while keeping your data in Europe under GDPR protection.

No, Flatpay does not require any binding contracts. You can start using the service and cancel at any time without penalties. There is no minimum contract duration, no notice period required for cancellation, and no exit fees. This is one of Flatpay's key differentiators from traditional payment processors that often lock merchants into 12- to 36-month agreements.

Flatpay terminals accept all major card types including Visa, Mastercard, and local card schemes. The terminals also support contactless NFC payments, including Apple Pay, Google Pay, and Samsung Pay. Both chip-and-PIN and contactless tap payments are supported, all at the same flat 0.99% rate regardless of the payment method used.

Flatpay is designed for fast onboarding. Merchants can sign up online, complete business verification, and receive their terminal hardware within days. The terminal setup itself is straightforward, requiring only a power connection and WiFi or mobile data signal. Flatpay provides dedicated support throughout the onboarding process to ensure a smooth transition.

Flatpay typically settles funds to merchants' bank accounts within one to two business days. There are no additional charges for settlement. Merchants can track their payouts and transaction history in real-time through the Flatpay merchant dashboard, which is accessible via web browser and mobile devices.

Yes, Flatpay's 0.99% flat rate is significantly lower than SumUp's typical 1.69% transaction fee in most European markets. For a business processing 10,000 euros per month, Flatpay would cost 99 euros compared to SumUp's 169 euros, saving 70 euros monthly or 840 euros annually. However, SumUp offers a broader range of additional software features beyond payment processing.

Flatpay initially launched in Denmark and has been expanding across Europe. The company is actively entering new European markets, adapting its offering to comply with local regulations and support local payment methods in each country. Check Flatpay's website for the most current list of available markets.

Flatpay is built as a European alternative to Square: Simple card payment terminals. It will not be a like-for-like feature match in every respect, so check the review above for where the two genuinely differ before switching.
