Best Payment Platforms for UK Accounting Firms [2025]

For many accounting firms, managing payments is still tied to outdated processes — whether it’s uploading BACS files, handling delayed payouts, or chasing clients for bank details. But as the UK shifts further toward digital finance, Open Banking is offering a better way.

Open Banking-powered payment platforms allow accountants to initiate real-time account-to-account (A2A) payments, automate vendor disbursements, and even help clients pay invoices faster — all while maintaining control and full auditability. These tools not only save time but also reduce fees, simplify reconciliation, and improve client experience.

In this guide, we’ve reviewed five reliable Open Banking payment platforms built to help accounting firms improve their payment workflows — from supplier payments to payroll runs and client billing.

Finexer

Built for UK Accounting Firms — Fast, Flexible, and Fully FCA-Authorised

Finexer is a purpose-built Open Banking platform for UK accounting firms that want fast payments, fewer manual tasks, and a branded experience their clients can trust. Unlike generic payment providers, Finexer focuses on the specific needs of modern accounting practices — from real-time reconciliation to smart onboarding and bank data automation.

Whether you’re collecting payments, managing client accounts, or verifying income — Finexer helps you do it all through one secure platform, with full UK bank coverage and pricing that scales with your business.

What you get with Finexer:

• Connects to 99% of UK banks – Real-time bank feeds that automatically sync transactions and eliminate manual uploads
• Real-time A2A payments – Send or receive payments instantly with no cards, files, or batch delays
• 3x faster deployment – Go live quickly with streamlined setup, tailored onboarding, and live testing support
• Automated reconciliation – Categorised transaction data with merchant names and timestamps for faster bookkeeping

• White-label ready – Offer clients a modern, branded platform under your firm’s name
• Affordable, usage-based pricing – No minimums or hidden fees — perfect for small firms and growing practices

Why Finexer Stands Out

Unlike other providers that cater to high-volume payment platforms, Finexer was made for the everyday needs of UK accountants. From streamlining expense tracking to accelerating client onboarding, everything is designed to save time, reduce admin, and keep you compliant — without the overhead of legacy systems or custom contracts.

If your firm is looking for a faster, easier way to handle payments and client data — Finexer delivers all of it, with none of the noise.

Modulr

For Embedded Payments and Scalable Infrastructure

Modulr is a well-established payments platform offering direct access to UK schemes like Faster Payments, Bacs, and CHAPS. It’s not just an Open Banking provider — it’s closer to a full payment infrastructure layer, designed for platforms that need to build complex or high-volume flows.

It’s a strong fit for accounting firms and finance platforms looking to automate payroll, vendor payments, and treasury transfers with more control over how money moves and settles.

What you get with Modulr:

• UK payment scheme access – Connect directly to Faster Payments, CHAPS, and Bacs
• Virtual accounts – Create client-level accounts for easy segregation and reconciliation
• Custom integrations – Designed for teams building their own accounting or finance platforms
• Regulated as an EMI – FCA-authorised and PSD2-compliant for trusted fund handling
• Bulk payments and real-time monitoring – Strong operational tooling for scaling up

What to consider with Modulr:

• Not plug-and-play – Best suited for teams with technical resources
• Custom pricing – You’ll need to speak with sales to get a quote
• May be more than what smaller firms need – Ideal for those offering embedded payments or servicing multiple clients

Modulr works well if your firm or platform is handling high payment volumes and needs embedded finance capabilities. It’s a step up in infrastructure — but may be overkill if you’re just looking for a quick way to send A2A payments with minimal setup.

Yaspa

Simple, FCA-Approved Payments for High-Risk and Regulated Sectors

YASPA is a UK-based Open Banking platform designed to offer frictionless payments for industries where compliance and transparency are critical. That includes accounting firms, lenders, legal services, and sectors that typically struggle with card acceptance or face high chargeback risks.

It focuses on making real-time A2A payments as simple and secure as possible — without forcing you into complex integration cycles or enterprise-only pricing.

What you get with YASPA:

• Real-time A2A payments – Move money instantly between verified bank accounts
• FCA-registered – Fully compliant for use in regulated financial and professional services
• Plug-and-play setup – No-code flows and fast onboarding help you go live quickly
• Built for compliance-heavy use cases – Great for firms needing bank-verified payment sources
• Merchant dashboard – Track payment status, initiate refunds, and manage clients in one place

What to consider with YASPA:

• Currently UK-focused – Not suitable if you’re operating across multiple currencies or regions
• Limited developer features – API options exist, but not as robust as some larger players

YASPA is ideal for firms that want secure, FCA-registered payment tools that “just work” — without needing to build custom flows or manage developer resources. If your focus is local, compliant, and efficient payments, it’s a solid choice.

Token.io

Pan-European Open Banking Infrastructure for Payment Platforms

Token.io is built for businesses that need to move money across borders — especially within the UK and EU. It’s one of the more established Open Banking platforms when it comes to multi-country support, offering a single API to initiate account-to-account payments across a wide bank network.

It’s ideal for firms that are building their own payment layer, supporting clients across Europe, or integrating Open Banking into a broader fintech stack.

What you get with Token.io:

• Pan-European bank connectivity – Initiate A2A payments across the UK and EU
• Single API integration – Simplifies connectivity to hundreds of banks
• Supports one-off and bulk payments – Ideal for platforms managing recurring payouts
• Regulatory compliance baked in – PSD2-ready and FCA-authorised for UK usage
• Flexible use cases – Works well for financial platforms, SaaS, and enterprise payment flows

What to consider with Token.io:

• Not UK-specific – Broader coverage may be unnecessary for local-only firms
• No no-code features – Best suited for teams with development resources
• Data access not included – Token.io focuses on payments, not bank data aggregation

Token.io is built for scale — especially if you’re operating across multiple countries and want to consolidate Open Banking payments under one platform. It’s not the fastest to deploy, but for cross-border platforms and enterprise-grade workflows, it’s a strong contender.
