White Label Payment Portals for Branded B2B Payments

B2B payments are still painfully clunky and it’s costing businesses millions. While consumer payments now happen with a single click, many B2B finance teams remain stuck with paper checks, manual entry, painful reconciliation processes, and systems built long before today’s digital economy.

According to a recent PYMNTS Intelligence tracker, 73% of B2B companies have yet to automate supplier payments. These outdated workflows slow down collections, complicate reconciliation, and create unnecessary friction for customers.

At the same time, check and cash payments have dropped from a majority share of B2B transaction value in 2019 to just 32.1% in 2024. Yet many businesses are still offering generic, off-brand payment experiences that do little to reinforce trust or improve cash flow.

The shift to digital is well underway. But going paperless isn’t the finish line. The real opportunity to turn payment friction into a competitive advantage lies in creating branded, seamless payment experiences that reflect your business professionally. This way, every interaction becomes a chance for your business get paid faster while maintaining trust and strengthening customer relationships.

But before diving into solutions, there's some foundational confusion worth clearing up first. Keep reading to learn more about:

What is a Payment Portal (vs Gateway vs Processor)?

A Payment Portal is the customer-facing storefront. Think of it as your payment dashboard where customers review invoices, see payment history, and complete transactions. It's what your customers interact with directly.

A Payment Gateway, on the other hand, is the routing system that sits between your business and payment processors. It encrypts and transmits payment data, and in advanced setups, can route transactions to one or more processors based on factors like transaction type, currency, geography, or processing costs.

And finally, a Payment Processor is the entity that executes the transaction. It transmits payment details through the card networks, obtains authorization from the customer’s issuing bank, and settles funds to your acquiring bank. It is the operational backbone of the payment system and ensures that money flows from the customer to the merchant.

Here’s a simple analogy using the process of sending mail:

1. Payment Portal = The Mailbox
   The portal is the mailbox where you drop your letter (your payment information). You see the envelope, write the address, and place it inside.

2. Payment Gateway = The Postal Sorting Center
   The gateway is the sorting center that reads the address, checks if it is valid, and routes the letter to the right destination while keeping it secure.

3. Payment Processor = The Mail Trucks and Delivery System

   The processor is the delivery system that moves the letter to its destination, working with the necessary networks to ensure it arrives.

While these terms are often used interchangeably, understanding the distinction is crucial, especially when you're evaluating solutions that need to represent your brand professionally.

What Is a White Label Payment Portal?

A white label payment portal is essentially a fully customizable payment interface that you can brand as your own. It uses an underlying payment infrastructure (like Stripe), but looks and feels 100% like your business. Unlike generic payment solutions that redirect customers to third-party branded pages, white label portals maintain your company's visual identity and domain throughout the entire payment experience. Here's what this means in practice:

Technical Infrastructure: The portal connects to enterprise-grade payment processors (like Stripe) through secure APIs, handling tokenization, encryption, and PCI compliance automatically. Your customers never see the underlying provider's branding or interface.

Brand Consistency: Every element reflects your company identity:

• Custom domains: payments.yourcompany.com instead of genericpayments.com/yourcompany

• Complete visual control: Your logo, colors, fonts, and styling

• Tailored payment methods: Offer only what makes sense for your business

• Branded communications: Every email and notification carries your company's voice

Integration Capabilities: Modern white label portals connect directly to your existing financial systems:

• Real-time synchronization with ERP systems

• Automatic invoice matching and payment allocation

• Customer account updates across all systems

Operational Control: Finance teams gain administrative capabilities typically reserved for in-house solutions:

• Automated dunning sequences with your branding

• Detailed transaction reporting and analytics

• Role-based access controls for team members

The key differentiator is ownership of the customer experience. When customers pay through your white label portal, they're engaging with your brand throughout the entire transaction, which measurably improves payment completion rates and customer perception.

Benefits of a White Label Payment Portal

Let’s look at the numbers that drive decisions.

• Consistent Brand Experience: When customers see your logo, colors, and messaging throughout the payment process, it builds trust. And trust matters: Forrester research reveals that B2B buyers who trust a vendor are nearly twice as likely to recommend them or pay a premium.

• Easy Tracking and Reconciliation: Finance teams currently waste 42% of their time on manual data processing, according to PwC. A white label portal changes this by feeding clean, structured payment data directly into your systems - making reconciliation nearly automatic.

• Higher Adoption of Online Payments: Your customers want self-service options. About one-third (37%) of B2B decision-makers prefer completing high-value purchases through digital channels, and a branded payment portal delivers exactly that without forcing them to navigate unfamiliar third-party systems.

• No/Minimal Engineering Setup: The World Economic Forum identifies “plug-and-play” financial infrastructure as a key trend in embedded finance, and white label portals deliver exactly that: full brand control and professional payment experience deployed in days, not development cycles.

• PCI compliance inheritance: Payment portals built on platforms like Stripe leverage the provider’s Level 1 PCI compliance, which can dramatically reduce the scope and cost of a merchant’s own PCI validation. Large merchants can avoid on-site audits that cost $25,000 to $50,000 annually, while SMBs often drop to a short self-assessment and save thousands in compliance costs.

Should You Build Your Own Payment Portal?

So, you’re convinced a branded, white-label payment portal can transform your payment experience. Now the next logical question is: do you build it in-house or leverage a plug-and-play solution?

Building Your Own Portal In-House

The decision to build a white label payment portal involves far more complexity than most finance teams initially recognize. While the DIY approach might seem cost-effective on paper, the reality involves significant technical, compliance, and operational challenges that extend well beyond initial development.

Technical Challenges

Your development team excels at building your core product. Payment portals require different specialized skills:

• Frontend developers experienced in payment UX and security best practices

• Backend engineers who understand webhook handling and payment reconciliation logic

• Integration specialists who can connect payment data to your ERP systems reliably

• Security experts who can implement PCI-compliant data handling

Compliance Challenges

PCI compliance creates permanent obligations, not just initial certification:

• Annual security assessments and vulnerability scans

• Quarterly compliance reports and documentation

• Immediate response protocols for security vulnerabilities

• Staff training and certification maintenance

Operational Challenges

Internal payment systems create new responsibilities that require dedicated resources:

• 24/7 system monitoring and incident response capabilities

• Payment failure investigation and customer support

• Regular security updates and system patches

• Integration maintenance as ERP systems and payment processors evolve

Leveraging a Plug-and-Play Payment Solution

Modern white label payment solutions offer a different path: one that prioritizes speed, security, and proven performance.

The best payment solutions are built on proven infrastructure like Stripe’s white-labeled platform, inheriting enterprise-grade security standards and global scale. This means you get professional payment processing with PCI Service Level 1 compliance from day one.

These solutions typically include:

• No/low code deployment means you can launch a fully branded payment portal in days, not months

• Built-in compliance eliminates ongoing PCI audit costs and security infrastructure investments

• Custom domain support gives you complete branding control with payments.yourcompany.com

Advanced solutions like Upflow go further by offering capabilities that most providers don’t:

• Pre-built enterprise connections to major ERP systems (NetSuite, QuickBooks, Sage) with established data flows and error handling

• Embedded payment capabilities let you integrate payment options directly into your website and email communications

• Card fees pass-through options help you manage transaction costs transparently

• White-glove migration assistance ensures smooth deployment with dedicated support (see how we helped Flinks migrate high-volume payments)

• 24/7 operations support ensures payment uptime without internal monitoring requirements

Here’s how the two approaches compare:

Making the Decision

For most organizations, deciding between the two hinges on three key factors:

1. Core business focus: Does building custom payment interfaces represent a strategic differentiator, or would development resources be better invested in your primary business capabilities?

2. Risk tolerance: Can your organization accept the ongoing maintenance, compliance, and operational risks associated with managing payment portal infrastructure?

3. Total cost analysis: When factoring in all development, maintenance, compliance, and opportunity costs, does internal development provide clear economic advantages?

For the majority of B2B companies, white label payment portals provide superior ROI while allowing finance teams to focus on strategic initiatives rather than payment interface management.

Summing Up

The future of B2B payments isn’t just digital. It’s branded, seamless, and customer-centric. A white label payment portal transforms what’s often the most friction-filled part of the customer experience into an opportunity to reinforce trust and professionalism.

While building your own payment infrastructure might seem appealing, the reality is that modern businesses need solutions that work from day one. Upflow's white label payment portal offers the perfect balance: enterprise-grade security and functionality with complete brand control and rapid deployment.
