Flatpay Review 2026

Last updated: May 2026

What Is Flatpay?

Flatpay is the European payment terminal provider with transparent flat-rate pricing for SMBs. Founded in Denmark in 2022, Flatpay challenges traditional card processors that charge variable percentages depending on card type, transaction size, and unclear fee structures. Flatpay charges one flat rate regardless of card type.

The pitch is predictability. Most European SMBs sign with payment processors that quote a "starting" rate but actual statements show different effective rates after interchange, scheme fees, premium card surcharges, and other variables. Flatpay's flat rate eliminates these surprises.

The product covers physical card terminals for retail, restaurants, salons, and service businesses, plus mobile readers for businesses on the move. Settlement happens in 1-2 business days. Most onboarding completes within a week.

How Flatpay Works

Sign up online with business information and bank details. Compliance verification typically completes within 3-5 business days. Once approved, Flatpay ships your terminal hardware.

Terminals come pre-configured for your account. Plug in, connect to internet (wired or 4G), and start accepting cards. Standard EMV chip-and-PIN, contactless (NFC including Apple Pay and Google Pay), and traditional magstripe all supported.

Pricing is flat per transaction: typically 0.99% to 1.49% depending on tier and transaction volume. No per-transaction fixed fee on most plans. No surcharges for premium cards, corporate cards, or American Express. The rate you sign on is the rate you pay.

Settlements transfer to your bank account in 1-2 business days. Statements show every transaction with the same flat rate applied. No reconciling effective rates against quoted rates.

Reporting dashboards show daily revenue, transaction counts, and reconciliation views. Integration with major POS systems (Square, Lightspeed, Vend) and accounting platforms (QuickBooks, Xero) feeds data into existing workflows.

Flatpay Pricing in 2026

Terminal rental: €19-€29/month per terminal depending on model.

Transaction rate: Flat 0.99% to 1.49% based on monthly volume tier. Higher volume tiers earn lower rates.

No setup fees, no PCI compliance fees, no statement fees: the rate is the rate.

Compared to traditional processors quoting 1.6%+0.10 + variable fees, Flatpay typically saves 0.3-0.6% on effective rates. For a business processing €100,000/month, this translates to €300-€600/month in savings.

Where Flatpay Wins

• Transparent pricing: one rate, predictable bills.
• No surprise fees: no per-transaction, no premium card surcharges, no scheme fee passthrough.
• Fast onboarding: account live within a week.
• Modern terminals: contactless, mobile wallets, EMV all supported.
• European focus: tuned for Nordic and Western Europe regulations.

Where It Falls Short

• Limited geographic coverage: Denmark, Netherlands, Germany, expanding to other markets.
• No US offering: not for businesses outside Europe.
• Smaller brand than SumUp or Stripe Terminal: less recognition in procurement.
• Online-only model: physical terminals only, no native e-commerce gateway (use Stripe online).

Flatpay vs SumUp vs Stripe Terminal vs iZettle

SumUp is the European card reader category leader with similar SMB focus. Comparable pricing.

Stripe Terminal targets developers wanting custom integrations. More flexible, more technical setup.

Zettle by PayPal (formerly iZettle) has wide European presence with similar pricing model.

Adyen targets enterprise European businesses with broad omnichannel payments.

Who Should Use Flatpay

European SMBs tired of variable card processing fees: predictability is the main value.

Retail and restaurant businesses: physical card payments at counter.

Service businesses with mobile teams: trades, beauty professionals, food trucks.

Skip it if: you operate primarily online (use Stripe), outside Flatpay's coverage areas, or need enterprise omnichannel.
