Integrated payment solutions for growing UK businesses

As your business grows, it’s important that everything flows easily. But manual payment processing can create a bottleneck at the most important time, slowing down your operations and cash flow. Integrated payment solutions, on the other hand, connect your payment processes with your existing tools, eliminating data entry, speeding up transactions, improving liquidity and allowing you to offer flexible terms without added risk. The result is a payment system that actively supports your growth, rather than holding it back.

What are integrated payment solutions and how do they work?

Integrated payment solutions are systems where payment processing is built right into the business software you already use. 

This could be your Point of Sale (POS) system in-store, your website for integrated online payment solutions, an app, or even your company-wide Enterprise Resource Planning (ERP) software for ERP integrated payment solutions.

An integrated online payment system can operate as a central hub for your sales and money. Instead of a separate card machine or an online payment page that doesn’t talk to anything else, an integrated setup means every payment automatically updates everything else – sales records, customer accounts, stock levels and your accounting software.

How do integrated payment solutions work?

When we talk about integration for payment solutions, it refers to software that can share data with other software in a secure, automated way to help your business work better. A typical flow could be:

  1. Your customer wants to pay (at your integrated point of sale payment solution, on your website, or via a payment link).
  2. Your business software captures the payment details.
  3. This software securely connected to an B2B payment gateway
  4. The payment gets the green light.
  5. Once processed, the information – amount, product, tax, terms – instantly updates your sales, CRM, inventory, and accounting.

What are the benefits of integrated payment systems for your business?

Switching to an integrated payment solution removes the need for manual steps and oversight in your payment workflow. This is especially important if you’re growing fast, working with different payment terms or working with rapid sales cycles. The benefits of integrated payment solutions for B2B companies include:

  • Less work per transaction:  Integration means less manual data entry for your team, fewer mistakes, and more reliable information to run your business. Solutions can update stock levels with every sale or send sales info straight into your accounts, making payment reconciliation simple and efficient.
  • Happier customers: A quick, easy, and flexible payment process makes life easier for customers. Integrated systems let them pay how they want (cards, digital wallets, even B2B Buy Now Pay Later) without jumping to confusing third-party sites. 
  • More sales: Offering more ways to pay, like popular digital wallets or flexible terms through B2B instalment payments, means more completed sales. 
  • Better data: With all your transaction info in one place, you get a clear, real-time view of your sales, what your customers like, and payment trends. This data is key for making smart choices about everything from marketing to stock.
  • Tighter security and compliance: Good integrated payment providers take security seriously, keeping customer data safe and sound (look for PCI DSS compliance). Managing compliance is also simpler with one system instead of many.
  • Fewer errors: Automation cuts down on human errors in data entry and reconciliation. Centralised security can also offer better protection against fraud.
  • Streamlined B2B service: For B2B sellers, these systems simplify managing trade credit accounts, payment terms on invoices and automated invoicing. 

Which businesses gain the most from integrated payments?

Just about any business can see benefits, but for some, integrated payments are especially impactful. This often includes businesses that:

  • Handle lots of transactions.
  • Use multiple payment methods and channels.
  • Need real-time data for stock, accounts, or customer management.
  • Need to give customers a smooth, modern experience.
  • Are looking to grow and need efficient, automated processes.

Key industries that can benefit include:

  • Retail and eCommerce: Integrated online payment solutions help optimise eCommerce payment processing, cutting down abandoned carts, and managing stock.
  • Wholesale & distribution: Quickly manage bulk transactions and real-time inventory updates.
  • Professional services: Easily tie proposals, invoices, and payments together from end-to-end for deals.
  • SaaS & subscription models: Reduce churn through automatic renewals and easier billing.
  • Construction & trades: Keep clear, up-to-date tracking of staged payments and project milestones.

How do I choose the right integrated payment solution for my industry? 

Choose a provider based on compatibility with your existing software, customer needs, and typical payment workflows. For example, if you're in B2B, does the solution handle complex invoicing, trade credit account management, and necessary B2B payment methods? A B2B specialist like iwocaPay, focused on flexible terms, including Pay Now and Pay Later options can give you the space you need to grow.

How do integrated payment solutions support Buy Now Pay Later?

Many trade customers expect flexibility on payments, but offering credit yourself ties up working capital and increases administrative workload. Integrated payments simplify this by embedding Buy Now Pay Later directly into your sales or invoicing flow.

  • Smooth checkout: Integrated systems can show BNPL as just another payment option in your usual checkout.
  • Quick credit decisions: For B2B BNPL providers like iwocaPay, integration means fast data sharing for credit checks and instant decisions on instalment plans. 
  • Simple reconciliation: Payments from the BNPL provider (who usually pays you, the merchant, straight away) mean there’s no waits for reconciliation or instalment payments.
  • Competitive payment terms: Integrated solutions make it easy to offer options like "Net 30" or "Net 60," without risking your capital

With iwocaPay, customers receive an invoice with an embedded payment link, letting them choose immediate or deferred payments. Importantly, you receive the full payment upfront, meaning no cash flow risk or credit management duties.

Can integrated payments help me offer flexible terms without cash flow risk?

Yes. Providers like iwocaPay enable you to offer BNPL embedded directly in invoices, while ensuring you get paid upfront, protecting your cash flow and removing credit risk from your business.

What to look for in an integrated payment provider

Selecting an integrated payment provider is about finding the right fit, not just the lowest cost. Consider carefully:

  • Ease of integration: It should work seamlessly with your current software.
  • Flexibility: Offer diverse payment methods, including immediate settlement and instalments.
  • Security: Ensure robust compliance (PCI DSS, FCA regulated).
  • Clear reporting: Real-time visibility into payments and cash flow.
  • User-friendly experience: Straightforward for both your team and customers.

Are integrated payment systems hard to set up?

No, not typically. Many solutions today offer simple, plug-and-play integrations with existing platforms. For example, iwocaPay's embedded payment links can be quickly added to your invoices or emails without technical expertise or development work.

How do integrated payment solutions affect cash flow and reconciliation?

Integrated payments reduce the time between payment, reconciliation and settlement by automating all the steps between. The result is more cash on hand and clearer visibility.

Manual reconciliation can slow your month-end close and obscure your true cash position. Integrated payments automate reconciliation, immediately matching payments to invoices and flagging overdue accounts promptly.

With clearer, real-time data, you can more accurately forecast cash flow, spot late payers faster, and make smarter financial decisions.

When should your business switch to integrated payments?

Waiting until your systems break can cause major headaches. Thinking ahead can set you up for success, with a system that helps you grow, rather than holding back.

There’s no hard and fast rule but check if:

  • Your team spends increasing time manually matching and chasing payments.
  • You experience frequent errors or inaccuracies in financial data.
  • Customers increasingly request flexible terms like BNPL.
  • Reconciling payments slows down your monthly reporting and decision-making.

Switching sooner rather than later lets your business scale more smoothly and efficiently.

Will integrated payments disrupt your existing processes?

Modern integrated payment solutions are specifically designed to minimise disruption. Rather than replacing your systems, they fit into your existing workflows with direct API connections that help data flow.

Providers like iwocaPay let you easily embed payments within your existing processes, meaning minimal training, no new software to learn, and immediate improvements in your financial operations.
