Flatpay is a payment solutions company that focuses on giving small and medium-sized businesses a simple, transparent way to accept card payments in person. Its proposition centres on a single, predictable flat rate per transaction — with no monthly subscriptions, no hidden charges, and a full-service setup experience that includes on-site installation and 24/7 support. The terminal product is built around the PAX A920 Pro, a portable Android-powered touchscreen device that supports contactless, chip and PIN, and digital wallet payments.
Flatpay positions itself as a direct alternative to payment processors that layer complexity onto their pricing — variable rates, monthly plans, and extra charges for features merchants only discover after they sign up. Its stated mission is to eliminate hidden fees and outdated hardware, and to replace them with a better payment experience.

Flatpay Pricing: Fees and Costs Explained
Flatpay’s pricing model is built around a single flat rate that applies to every card transaction. There are no tiered plans, no monthly fees, and no charge to get started. The rate you pay depends on your annual card turnover.
- Below £200,000 annual card turnover: 1.49% per transaction — applies to all card types including debit, credit, Visa, Mastercard, and contactless. There is no split between card types at the headline rate, making budgeting straightforward.
- Above £200,000 annual card turnover: Custom rate — negotiated directly with the Flatpay sales team. Larger-volume merchants should contact Flatpay directly for a tailored quote.
What Is Not Charged
Flatpay is transparent about what is not included in its fees. Merchants are not charged for monthly subscriptions or platform fees, setup or onboarding fees, 24/7 customer support access, merchant portal access, or enabling the surcharge feature.

Flatpay Hardware: The PAX A920 Pro Terminal
Flatpay’s payment terminal is the PAX A920 Pro — a widely used Android-based touchscreen device in the card payments industry. It is a handheld, portable unit with a built-in thermal receipt printer, making it well-suited for counter use and tableside payments alike. The terminal connects over both Wi-Fi and 4G, with a SIM card pre-installed in the box so it is ready to use immediately without any additional mobile contract or data plan to arrange.
Hardware Specifications
- Android operating system with automatic software updates to maintain system integrity
- NFC contactless payments — supports tap-to-pay cards and digital wallets
- Wi-Fi and 4G connectivity — pre-installed SIM card included
- Fast integrated thermal receipt printer built into the device
- Accepts Visa, Mastercard, Apple Pay, Google Pay, and contactless — covers the full range of payment methods UK customers commonly use
- Sleek, compact design suitable for countertop or handheld use
What’s in the Box
Every Flatpay package includes everything needed to start taking payments immediately:
- PAX A920 Pro terminal
- USB-A to USB-C charging cable and 5V 2A 10W power supply
- Terminal stand
- Pre-installed SIM card — ready for 4G connectivity out of the box
- Roll of receipt paper
- Accessibility sticker with tactile knobs for visually impaired customers
- Window sticker with Flatpay branding and accepted card types
Getting Started: The Flatpay Onboarding Process
Flatpay’s approach to onboarding is notably hands-on compared to many payment providers that simply ship hardware and leave merchants to configure it themselves. The process runs in three stages, designed to get merchants operational quickly and with minimal technical effort on their part.
- Step 1 — In-Person Meeting: A Flatpay representative visits the business, discusses its needs, and provides a personalised walkthrough of the product. This is not a remote or self-service process — a real person comes to you.
- Step 2 — Tailored Offer: At the end of the consultation, the merchant receives a proposal designed around their specific requirements. For businesses under £200,000 per year in card turnover, the 1.49% rate applies. For higher-volume merchants, a custom rate is discussed.
- Step 3 — On-Site Installation: Flatpay manages the full installation of hardware and software at the merchant’s premises. There is no expectation that the business owner will configure the terminal themselves — the Flatpay team handles setup and provides training before they leave.
Flatpay Surcharge: What It Is and How It Works
Flatpay offers an optional surcharge feature that allows merchants to pass on the higher processing cost of certain card types to the customer at the point of payment. In the UK, eligible cards are international cards and business cards. Standard UK consumer cards — the type most customers use day to day — are not subject to surcharging. Enabling and using the surcharge feature is completely free for merchants.
How It Works
When a customer pays with an eligible card, a surcharge of 3.89% is applied automatically to the transaction total. The surcharge amount is displayed on the terminal screen before the payment is confirmed, and is itemised on the printed receipt — so the customer has full visibility and the choice to proceed before committing.
Surcharge Example
☕ A coffee is priced at £5.00
✓ Customer paying with a standard UK card pays £5.00 — no surcharge
→ Customer paying with an international card pays £5.19 — 3.89% surcharge applied automatically
ℹ The merchant pays 0% on eligible transactions — the surcharge is funded by the customer, not deducted from the merchant’s payout
Communicating Surcharge to Customers
UK regulations require that customers are informed about surcharges before they pay. Flatpay recommends informing customers at the point of entry or at the till using visible signage — the surcharge window stickers Flatpay provides are designed for this purpose. Staff should also be briefed to explain the surcharge simply and clearly if customers ask. The terminal automatically displays the surcharge amount before the transaction is finalised, so the process is transparent by design.
How to Enable Surcharge
- Step 1: Contact Flatpay Support at info@flatpay.co.uk or +44 2080289990
- Step 2: Flatpay confirms eligibility for your country and industry
- Step 3: Once approved, the feature is activated on your account and you are notified when it is live
- Step 4: Run a test transaction to see how the surcharge appears before using it with customers
Payouts: How and When You Get Paid
Flatpay aims to provide next-day payouts to all merchants, meaning funds collected through the terminal are settled into the merchant’s bank account the following business day. The company notes that this is subject to banking days, weekends, and cut-off times, so payouts may occasionally be slightly delayed around bank holidays. For small businesses managing cash flow, reliable next-day settlement is a practical benefit — it reduces the number of days that revenue sits in a payment processor’s account rather than your own.
Flatpay Software Features
Every Flatpay merchant gets access to an online Merchant Portal with real-time reporting — included as standard with no additional charge. The portal allows you to track sales trends and transaction history, view daily turnover and payout reports, and grant access to accountants or bookkeepers directly.
Terminal Software
- Sales and refund processing
- Print last receipt — reprint the most recent receipt on demand
- Z-reports (end-of-day) and X-reports (interim sales summary)
- Transaction history and Z-report history
- Automatic receipt printing or “ask customer” prompt to reduce paper waste
- Tip acceptance — can be enabled or disabled, ideal for hospitality
- Merchant reference field for adding order or table references
- Language selector and default to sales screen for faster transactions
Flatpay Support: 24/7 Help When You Need It
Flatpay provides 24/7 support via both phone and email — included as standard with no premium plan required. For businesses that trade outside standard office hours, such as restaurants, bars, and events venues, this is a meaningful practical benefit rather than a marketing claim. Payment issues do not wait for business hours.

Who Is Flatpay Best Suited For?
Flatpay is designed primarily for face-to-face retailers, hospitality businesses, and service providers who want a reliable card terminal with straightforward pricing. Based on its published product details, it is likely to be a strong fit for the following types of business:
- Cafés, restaurants, and bars — high volume of in-person transactions, value speed at the point of sale, and often benefit from the tip acceptance and surcharge features
- Independent retailers and boutiques — looking for a simple alternative to complex payment plans with no monthly fees
- Seasonal businesses — the annual assessment of the minimum turnover requirement provides flexibility, though this should be reviewed carefully before signing up
- Service businesses such as salons, clinics, and tradespeople who need a portable terminal with 4G connectivity for use away from a fixed counter
- Businesses handling international customers or business card payments regularly — the surcharge feature allows those higher processing costs to be passed on rather than absorbed
Important: Flatpay is primarily a card-present solution built around the physical payment terminal. Businesses that need substantial online payment processing or ecommerce functionality as a primary channel should verify current capabilities directly with Flatpay before signing up.
