The future of integrated payments: Optimising payment solutions with open banking

Digital transformation is now a cornerstone of success across virtually every industry, and integrated payments are playing a central role in this evolution. While integrated payment solutions have already reshaped how businesses manage transactions, the integration of open banking is accelerating this transformation. Rather than being a future concept, open banking is actively enhancing the functionality of integrated payments by enabling faster, more secure, and cost-efficient financial operations.

This article explores the future of integrated payments through the lens of open banking, highlighting the technologies, benefits, sector-specific applications, and innovations shaping a smarter, more connected payments landscape.

What are integrated payment solutions?

Think of a busy café or retail shop. Every time a customer makes a payment, several things happen behind the scenes: the transaction must be processed, inventory updated, accounts adjusted, and reports generated. If these systems don’t work together, it’s like juggling each task manually which is time-consuming, error-prone, and inefficient.

Integrated payment solutions eliminate this friction by seamlessly connecting a business’s payment processing with its broader software ecosystem — such as point-of-sale (POS) systems, accounting platforms, inventory management, and customer relationship management (CRM) tools. As a result, payment data flows automatically across departments, reducing manual input, minimising errors, and improving operational efficiency.

But integrated payment solutions go beyond just linking systems. They provide a purpose-built framework for accepting and managing transactions within the tools businesses already use. Whether it’s processing card payments at a till, reconciling transactions in accounting software, or generating real-time sales reports, these solutions ensure everything works in harmony.

One of the key strengths of integrated payment solutions is their ability to act as a central hub for financial operations. They offer features like automated reconciliation, compliance support, advanced analytics, and customer insights — all accessible through a unified interface. This empowers businesses to make quicker, data-driven decisions, enhance customer experiences, and significantly reduce administrative overheads.

Moreover, these solutions are often developed in collaboration with independent software vendors (ISVs) to deliver tailored, industry-specific functionality. For sectors such as healthcare, education, retail, and professional services, this means integrated payments can address unique workflow and compliance needs more effectively.

Ultimately, while integrated payments refer to the seamless flow of transaction data across systems, integrated payment solutions optimise these connections to support business growth, improve accuracy, and future-proof financial operations in an increasingly digital economy.

Exploring ISV integrated payments

As integrated payments continue to evolve, one of the most impactful developments has been the emergence of ISV integrated payment solutions. These are created through partnerships between payment providers and independent software vendors, enabling businesses to access highly tailored, industry-specific functionality within the software platforms they already use. This collaboration delivers a more seamless, flexible, and scalable payment experience which is tailored to the unique operational needs of different sectors.

Key advantages:

• Workflow efficiency: Payments can be processed directly within the software a business already uses, reducing the need to juggle multiple systems or interrupt key processes.
• Customisation: ISVs often tailor their integrated payment features to suit the unique needs of their audience, such as booking and billing tools for appointment-based services or retail-specific sales integrations.
• Scalability: As businesses grow, ISV integrated solutions can scale alongside them, making them suitable for everything from start-ups to enterprise-level organisations.

For example, a SaaS platform designed for fitness centres might include an integrated payments module that automates membership billing, tracks class attendance, and manages subscriptions, all from a single dashboard.

How do integrated payments work?

A well-designed integrated payment solution should connect seamlessly with a business’s existing systems such as point-of-sale (POS) or inventory management, and accounting platforms without compromising security, performance, or ease of use.

In a typical retail environment, for instance, a customer’s purchase initiates a series of automatic processes. The payment data is instantly synced with inventory levels, financial records, and sales reports, ensuring real-time visibility and accuracy across the business. This level of integration not only saves time but also minimises errors and improves decision-making.

Modern integrated payment solutions leverage advanced technologies to deliver increasing functionality over time. According to recent studies, businesses that adopt these systems have reduced transaction processing times by up to 45%, and cut down on manual data entry by 60%, freeing up staff to focus on higher-value tasks.

Step by step process to integrate payments into an app

For developers or businesses building apps, adding integrated payment functionality typically involves working with APIs (Application Programming Interfaces) or SDKs (Software Development Kits) provided by the payment service provider. Below is a simplified overview of the process:

1. Choose the right integrated payment solution
   Evaluate providers such as Stripe, PayPal, or Wonderful, depending on your app’s specific needs, whether it's recurring billing, international transactions, or open banking compatibility.
2. Register and create a merchant profile
   Sign up with the chosen provider and set up your account. This will involve submitting your business details and bank information, and completing KYC (Know Your Customer) and AML (Anti-Money Laundering) checks.
3. Generate your API keys
   Once verified, the provider will issue API credentials—typically a public key and a secret key—for secure integration.
4. Integrate using the API or SDK
   Use the provider’s SDK (e.g., Stripe SDK for iOS or Android) alongside their REST API to implement payment features. This may include integrating a payment gateway, enabling secure card storage, or supporting multiple digital wallets.
5. Test the integration
   Most providers offer sandbox environments to test the payment workflow thoroughly before going live, helping you identify and resolve any issues in advance.
6. Ensure security compliance
   Adhere to relevant standards such as PCI-DSS (for card payments), implement encryption, and tokenisation to safeguard sensitive payment data.

Sample use case:

A fitness app could use integrated payment APIs enabling users to make subscription payments for memberships, book classes, pay for personal training sessions, or subscribe to monthly memberships, all without leaving the app. This enhances the user experience and streamlines back-end operations.

By embedding payments directly into digital experiences, businesses can deliver a smoother, faster, and more secure checkout process, boosting both customer satisfaction and operational efficiency.

Open banking as a change agent in financial visibility

Merging open banking with integrated payment solutions fundamentally transforms how businesses approach and manage their financial operations. It enables greater transparency, real-time financial insights, and more efficient cash flow management. Direct connectivity allows businesses to better understand their financial objectives. This goes beyond basic transaction-level data, offering real-time account balances, up-to-date payment statuses, and comprehensive transaction reports.

Through integrated payments, organisations can access real-time financial data across their entire operation, which can help them with more accurate cash flow forecasting and working capital optimisation. For example, an enterprise may work with multiple suppliers and use this enhanced visibility to better manage those relationships—identifying optimal payment timings to take advantage of early payment discounts. According to market data, organisations that employ these capabilities realise a 45% increase in cash flow accuracy and a decrease in their working capital requirement of up to 30%.

Best practices for implementing integrated payment solutions

Successfully implementing integrated payment solutions, particularly those leveraging open banking, requires careful planning that addresses both technical and organisational considerations. Businesses must manage complex requirements while ensuring minimal disruption to existing operations and maintaining high-security standards throughout the transition.

Technical infrastructure and integration planning

Effective implementation relies heavily on thorough technical planning and a comprehensive evaluation of existing infrastructure. The integration of open banking adds further complexity to this process. Organisations must assess their infrastructure's capability to manage multiple banking connections and handle real-time data streams, ensuring these connections remain secure and reliable at all times.

In most cases, this necessitates the adoption of new API management systems and the enhancement of existing security measures. Achieving this level of integration requires close collaboration between the organisation’s IT team, payment service providers, and banking partners.

Security and compliance considerations

The concepts of integrated payments and open banking are frequently accompanied by concerns about security. In this, an organisation should establish a fully fledged security framework that not only protects financial data but also meets regulatory requirements. The security of end-to-end encryption for data transmitted, effective mechanisms for authentication, and detailed audit trails of transactions would be among these.

Open banking is built upon Strong Customer Authentication (SCA). Companies that meet these guidelines reduce fraud by 60% and maintain customer satisfaction.

Change management and organisational readiness

The human aspect of implementation is often just as important as the technical side. Organisations must prepare their staff for new processes and systems, while also effectively communicating new payment options to customers. Before a full-scale rollout, processes should be fine-tuned and any issues resolved. Organisations that adopt this approach typically achieve implementation success rates up to 40% higher.
