What is Fiserv?

Fiserv is a leading global provider of financial technology and merchant services, supporting millions of businesses worldwide. In the UK, Fiserv offers a full suite of payment solutions designed to serve merchants of all sizes from small independent retailers to multinational enterprises.

The company’s portfolio includes acquiring services, point of sale (POS) hardware through the Clover platform, ecommerce gateways, virtual terminals, fraud prevention tools, and embedded finance services. Fiserv’s strength lies in delivering integrated, omnichannel payment infrastructure that gives businesses full control over how they accept, manage, and analyse payments across in-store, online, and remote channels.

Through its Clover system, Fiserv empowers SMEs with user-friendly hardware and software to manage sales, inventory, reporting, and customer loyalty. For larger and enterprise level merchants, the Carat platform offers sophisticated omnichannel capabilities, including tokenisation, smart routing, and realtime analytics to improve efficiency and conversion rates.

Fiserv also provides merchant acquiring, meaning it can process payments directly on behalf of businesses, offer settlement services, and support compliance and security standards like PCI DSS. Whether you need a single card terminal or an integrated solution across thousands of locations, Fiserv delivers enterprise grade reliability with the flexibility to meet the unique needs of UK merchants.

Key Features of Fiserv

  • Clover POS for Small Businesses
    Fiserv's Clover platform offers an all in one solution for small to mid sized merchants. With countertop, portable, and touchscreen POS systems, Clover helps you manage payments, inventory, staff, and loyalty in a single, intuitive interface. It’s ideal for cafes, salons, retail shops, and mobile businesses looking for simplicity and flexibility.
  • Carat for Enterprise Grade Omnichannel Support
    Carat is Fiserv’s solution for larger and enterprise level businesses that need to manage payments across multiple channels. It delivers a centralised platform for ecommerce, in-store, mobile, and subscription billing with tools for tokenisation, smart routing, and conversion optimisation. Carat is designed for scale and tailored to fit complex operations.
  • Global Acquiring and Payment Gateway
    With global acquiring infrastructure, Fiserv enables merchants to accept payments in multiple currencies and geographies. The integrated gateway supports Visa, Mastercard, ACH, Faster Payments, and CHAPS, ensuring reliable authorisation and settlement across the UK and internationally.
  • Flexible Terminal Solutions
    Whether you need a countertop terminal, mobile card reader, or integrated EPOS device, Fiserv’s terminal options, delivered via Clover and partners suit every environment. All devices support chip & PIN, contactless, Apple Pay, and Google Pay.
  • Virtual Terminal & MOTO Payments
    For merchants taking payments by phone or mail, Fiserv offers a secure browser based virtual terminal. This is ideal for service providers, call centres, and professional services that require a flexible, non customer present payment option.
  • Advanced Fraud and Risk Management
    Fiserv includes a full suite of fraud prevention tools, such as 3D Secure, AVS, CVV checks, and behavioural analytics. Businesses can reduce chargebacks, identify suspicious activity in realtime, and adjust risk parameters as needed.
  • PCI Compliance & Security Support
    Fiserv helps merchants stay compliant with PCI DSS and Strong Customer Authentication (SCA) requirements. Merchants receive guidance and access to tools that simplify the compliance process and reduce risk exposure.
  • Embedded Finance & Value Added Services
    Beyond payments, Fiserv offers embedded services such as consumer financing, digital receipts, loyalty schemes, and invoice payment plans. These tools help merchants drive customer engagement and grow revenue while simplifying back office operations.

Who Should Use Fiserv?

Fiserv is ideal for:

  • SMBs and chains seeking flexible POS systems and loyalty integration
  • Mid size to enterprise merchants requiring cross-channel orchestration
  • Hospitality, retail, and multi site operations needing back office tools
  • B2B businesses with Level 2/3 processing and invoicing endpoints
  • Agencies, councils, and associations using managed service fee models
  • Less suited for micro merchants due to setup complexity and minimum fees.

Pricing & How Fiserv Compares

Fiserv offers tailored pricing based on merchant size, risk, channel mix, and volume:

  • Transaction rates typically range from 0.9% to 2.5%, varying by merchant category; interchange passthrough applies.
  • Monthly fees cover gateway access, PCI compliance, reporting, and fraud modules, often between £9–£25 for SMEs.
  • Terminal leasing fees range from £15–£30/month depending on model and connectivity.
  • Setup/integration fees may apply for virtual terminals, multichannel setups, or enterprise installations.
  • Managed service models can eliminate per-transaction fees for agencies via blended service price.

Compared to Stripe or Square, Fiserv offers deeper hardware integration and business level features but lacks rate transparency. Against bank led acquirers like Barclaycard, Fiserv provides more tech functionality and merchant control. For large retailers, Carat offers a comparable alternative to Adyen or Worldpay.

Through Compare Card Fees, we negotiate optimal terms and fee reduction across Clover, Carat, and Carat integrated services.
