Integrated payment processing means the payment system is built directly into the software your business uses. In most cases, this means the software that manages your accounting, CRM, ecommerce platform, POS systems, or order management and billing can take payments without using a third-party payment application. Both software developers and payment processors describe integrated payments this way: payments embedded in the software your business uses.
A good payment processing integration goes beyond just adding a payment button to your software. It should reduce the manual entry your staff has to perform and make it easier to manage payments and financial records from the same system. Payment Nerds also describes integrated payments in the same way: fewer tools to manage and connect to, easier scaling of your software and integrations, and better reporting tools for the businesses that use them.
What Is Integrated Payment Processing?
Integrated payments is the ability to accept payments within the software the business is using. According to the official description of the concept, integrated payment processing means embedding the payment system directly into the software, enabling businesses to process payments without leaving the platform. This is the major difference between integrated payments and standalone payment processors.
An example of integrated payments is automatically closing an invoice or updating a customer record after a payment is processed. Companies like Payment Nerds, Fiserv, and Square describe the concept as payments being linked to a business’s systems, which automatically connect payments to orders, customers, subscriptions, and more.
Why Businesses Use Integrated Payment Processing in 2026
Businesses are turning to integrated payment processing systems to avoid the work required by disconnected systems. By integrating the payment system with other business systems, such as accounting and customer management software, staff members can complete manual work less often. As stated in payment-industry documentation for various software systems, integrating the payment system with other business systems enables data from the payment system to be automatically passed to those systems.
The second reason that many business owners are turning to integrated payment processing systems is that these systems are more scalable for growing businesses. As discussed in various articles published by Payment Nerds and other payment industry documentation, managing payments across different environments enables a business to handle its payments and grow with minimal additional effort. The same is true for articles published by the manufacturers of the most widely used payment systems for online and in-person businesses.
Who Needs Integrated Payment Processing?
This kind of system is most useful for businesses like:
- service businesses that invoice within their accounting software
- SaaS companies and platforms
- retail companies with POS and ecommerce websites
- health care, automotive, and service companies that use customer records
- software companies and ISVs that want to sell products with embedded payments
- companies with multiple locations
The more systems your business uses, the more you’ll find this kind of integration useful. A company that uses a single checkout page may not need this kind of functionality yet. However, as their payments need to connect with accounting and other systems, this will become increasingly important.
Integrated Payment Processing Options Compared
| Option | Best For | Main Strength | Main Tradeoff |
|---|---|---|---|
| Native software integration | Businesses using one core platform for billing or operations | Cleaner workflow inside the software people already use | Less flexibility if the business outgrows that platform |
| API-based payment processing integration | Businesses with custom software or more specific workflow needs | More control over checkout, reporting, and user experience | Requires more implementation work |
| Platform-based integrated payments | SaaS platforms, marketplaces, and software providers | Can onboard users, process payments, and manage payouts in one flow | More complexity around verification, payouts, and platform design |
| Connected payments across multiple systems | Businesses with several channels or departments | Better alignment across payments, customers, and reporting | Requires stronger planning across systems |
This comparison matters because not every integrated payment setup solves the same problem. Some businesses need invoice and accounting integration. Others need ecommerce, POS, and subscription systems tied together. Platform businesses may also need onboarding, split payments, and payout control. Official documentation from Payment Nerds, Fiserv, Adyen, and Square clearly reflects those different models.
How Much Does Integrated Payment Processing Cost?
There are several ways to evaluate the cost of integrated payment processing. Most payment industry resources will state that the value proposition of integrated payment systems is correlated with the rate of payments processed, the time saved in the payment process, and the reporting capabilities of those systems.
However, a more useful question is: what does the integration eliminate? If the integration can reduce the amount of work that is required to process payments in a back-office operation, eliminate errors in payment reconciliation, improve the customer experience with the business payment system, and provide better sales data for the business, then it will reduce the cost of processing payments, even if the payment rate is not the lowest available payment system.
Common Integrated Payment Processing Mistakes Businesses Make
While some companies make the effort to integrate their payment processes with their other business systems and workflows, they fail to accomplish true integration.
The company can integrate the payment process while keeping the accounting processes, customer information systems, order information systems, and reporting systems separate. This process will not improve workflow as much as anticipated.
Many companies also make the mistake of not integrating the PCI SSC security standards and recommended implementation, which were created for merchant processes. An integrated payment system with poor design can cause problems later.
How to Choose the Right Payment Processing Integration (2026)
Connect Payments To The System People Already Use
The best integration will start with the software that your employees use every day. If your employees work within accounting software, customer relationship management (CRM) software, enterprise resource planning (ERP) software, point-of-sale (POS) systems, or order management systems, you should integrate the payments system with that software.
Keep Payments, Orders, And Reporting In Sync
The integration should include an update function for the information that is critical to your business. Whether that is invoices, orders, customers’ accounts, refunds, or reporting for payments and payouts, the software should be able to update those records after each transaction occurs.
Support Online, In-Person, And Mobile Workflows
Most businesses today do not rely on a single way of taking sales. An integrated payment system should support online sales, in-person sales, sales through invoicing software, and mobile sales. Each of these channels should be encompassed under one integrated payments system.
Plan For Refunds, Disputes, And Payouts
Most sales and payment software includes the capability for refunds, so sales and returns are managed effectively. Additionally, the refund system should handle sales disputes, saved cards, subscriptions to products or services, and the ability to payout sales proceeds to a linked bank account.
Build Security Into The Integration
Security is part of building and integrating a payment system. The PCI Security Council has detailed how the PCI security standards will protect payment data throughout the sales and payment process. Additionally, their qualified integrators and resellers program ensures that those companies building and installing the software will incorporate security into their system.
Choose An Integration That Supports Growth
Most integrated payment system and software sales companies offer solutions that will support your growing business. For example, companies like Payment Nerds and POS software manufactures ensure that their system will support online (e-commerce), in-person, and mobile sales in the future. Additionally, the API documentation from companies like Shopify and Square ensure that sales and payment integrations can scale with your growing business.
