What B2B payment solutions are available for enterprises?
B2B payment solutions are platforms that help businesses manage, automate, and control how they pay other businesses. For enterprises, that means handling everything from invoice approval to payment execution and reconciliation, across multiple currencies, countries, and payment channels, all within your existing ERP environment.
Managing B2B payments at enterprise scale is one of the more complex challenges finance teams face. Payment teams must deal with invoice settlement, multi-level approvals, payment execution, and reconciliation, often across many different systems, channels, and geographies at once. Do it manually, and you’re looking at slow payments, poor visibility, and serious exposure to both errors and fraud.
In this article, we’ll walk through what B2B payment automation solutions actually do, the most common problems they solve, and a breakdown of the leading platforms worth evaluating in 2026, so you can make an informed decision about what’s right for your organization.
Why do enterprises need dedicated B2B payment solutions?
B2B payments aren’t just “bigger” versions of consumer payments. They’re fundamentally more complex. A single enterprise might be processing thousands of vendor invoices a month, managing approvals across multiple business units, dealing with suppliers in different countries, and working with a mix of payment formats including wire transfers, checks, ACH, SEPA, and more.
That complexity creates real problems. Payments get stuck in approval queues. Reconciliation takes days. Fraud slips through the cracks. Teams spend hours manually formatting payment files and chasing sign-offs via email.
Dedicated B2B payment solutions exist to fix this. They consolidate the payment lifecycle into a single workflow, integrate directly with ERP systems like SAP, and automate the steps that don’t need a human in the loop. That frees up finance teams to focus on decisions that actually need their attention.
What does B2B payment automation software actually do?
At its core, B2B payment automation software replaces a fragmented, manual payments process with a centralized, largely automated one. Instead of toggling between banking portals, ERP systems, spreadsheets, and email threads, your team works from a single platform that handles:
- Invoice capture and validation – Pulling payment requests from multiple sources and checking them against POs, contracts, or approval rules
- Approval workflows – Routing transactions to the right people automatically, based on amount, vendor, entity, or other criteria
- Payment execution – Formatting and submitting payment instructions to your banks in the right format for each country or payment rail
- Reconciliation – Matching completed payments back to open items in your ERP, automatically
- Fraud detection – Flagging anomalies in payment requests before they go out the door
Modern platforms also incorporate machine learning to handle the harder problems: identifying suspicious payment patterns, optimizing when payments go out to preserve working capital, and matching complex remittance data that wouldn’t reconcile without AI assistance.
5 problems B2B payment automation solves
-
Too much manual work in the payments process
Manual invoice approvals, payment file creation, and bank instructions all eat time. When transaction volumes are high, those hours add up fast. Payment automation eliminates the repetitive steps, so your team handles exceptions rather than every transaction.
-
Managing payments across multiple channels and geographies
Global enterprises often deal with dozens of different payment formats and banking standards. A solution built for B2B enterprise payments supports all the major rails (ACH, SEPA, SWIFT, wire, virtual card, and others) from one place, rather than requiring separate portals and processes for each.
-
Poor visibility into payment status and cash flow
When payment data lives in different banking systems, ERPs, and spreadsheets, getting a clear picture of what’s been paid, what’s outstanding, and what’s coming is difficult. A centralized B2B payments platform consolidates that data and gives treasury and finance teams real-time visibility into outgoing cash flows.
-
Fraud risk and compliance gaps
Business email compromise (BEC) and payment fraud are growing threats for large organizations. Modern B2B payment solutions use machine learning to automatically flag suspicious requests, such as changes to vendor bank details, unusual payment amounts, or transactions that don’t match prior patterns, before funds leave the account. They also maintain complete audit trails that satisfy regulatory requirements.
-
The cost and complexity of managing global payment infrastructure
Maintaining bank connections, updating payment formats, and staying current with regulatory requirements in multiple countries is an enormous operational burden. Managed payment services and cloud-based platforms take that maintenance burden off your IT and finance teams.

1. Serrala
Serrala offers a unified payment processing platform for enterprises, available in two deployment models depending on your infrastructure and compliance requirements.
The Cloud option connects with any ERP and covers the full payment processing lifecycle, including Pay by Link, Payments as a Service (PaaS), and Pain.001 automation. It’s a good fit for organizations that want flexibility across their ERP landscape without being locked into a single vendor ecosystem.
The SAP-Embedded option is built for clean-core SAP compliance and covers payment processing for SAP, cash management for SAP, and treasury for SAP. It’s designed for enterprises that want deep native integration within SAP S/4HANA without customizations that complicate upgrades.
Across both models, Serrala centralizes the payment lifecycle, from approval workflows and digital signatures to bank connectivity, payment file formatting, and exception handling. Advanced fraud detection uses ML to flag anomalies before payments are executed. The platform also connects with Serrala’s AP automation suite, so the workflow from invoice capture through to payment runs end to end without manual handoffs. Customers typically report up to 90% improvement in payment operational efficiency.
Best for: Enterprises looking to centralize and automate global payment operations, whether running SAP or another ERP, and whether they want to own the infrastructure or fully outsource its management.
Key capabilities include:
- Cloud and SAP-Embedded deployment options

How to choose the right B2B payment solution
The right choice depends on your organization’s size, ERP landscape, geographic footprint, and where your biggest payment pain points actually are.
Ask yourself these questions:
- How many payment transactions do you process each month, and across how many entities?
- Which ERP systems do you rely on, and how tightly do you need the payments solution to integrate?
- How many countries and currencies do you operate in?
- What’s your biggest current problem: fraud risk, manual workload, poor visibility, or compliance complexity?
- Do you want to own and manage your payments infrastructure, or would a managed service work better?
For smaller, simpler operations, a platform like BILL may be enough. For mid-market companies growing into more complex global operations, HighRadius or Airwallex may be worth evaluating. For large enterprises running SAP, especially those managing global payments across multiple subsidiaries with strict compliance requirements, a purpose-built solution like Serrala FS2 Payments or Serrala Payments as a Service is likely to offer the best combination of depth, scalability, and ERP integration.

Frequently asked questions about B2B payment solutions
What is a B2B payment solution?
A B2B (business-to-business) payment solution is a platform that helps companies manage how they pay other businesses. For enterprises, this typically means software that automates invoice approval, payment execution, bank connectivity, and reconciliation, usually integrated directly into an ERP system.
How are B2B payments different from consumer payments?
B2B payments involve much higher transaction values, more complex approval processes, multi-currency and cross-border requirements, and stricter compliance obligations. They’re also more vulnerable to fraud, particularly through business email compromise. Consumer payment tools aren’t built to handle this complexity.
What payment methods do enterprise B2B payment solutions support?
Most enterprise-grade platforms support ACH and direct bank transfers, SEPA (in Europe), SWIFT wire transfers, checks (physical and digital), and virtual or physical corporate cards. Some also support newer payment rails like real-time payments (RTP) and ISO 20022-compliant formats.
What is ISO 20022, and why does it matter for B2B payments?
ISO 20022 is a global messaging standard for financial transactions that’s being adopted by banks and payment networks worldwide. It allows richer data to travel with each payment, which improves straight-through processing and reconciliation rates. Enterprises migrating to SAP S/4HANA are increasingly required to ensure their payment processes are ISO 20022-ready. Serrala’s pain.001 automation is specifically designed to help organizations adopt this format without disrupting existing workflows.
How does B2B payment automation reduce fraud risk?
Modern payment platforms use machine learning to detect anomalies in payment requests, such as changes to vendor bank account details, payments to new beneficiaries, or amounts that fall outside expected ranges. These are flagged automatically before execution, without requiring manual review of every transaction.
What’s the difference between B2B payment software and Payments as a Service?
Payment software is a product your team deploys and manages. Payments as a Service (PaaS) is a fully managed model where a provider like Serrala handles the entire payments infrastructure on your behalf, including bank connectivity, format management, SWIFT onboarding, and platform operations. PaaS suits organizations that want to reduce IT overhead or don’t have the internal resources to manage complex payment infrastructure themselves.
How do B2B payment solutions integrate with SAP?
The best enterprise B2B payment solutions integrate natively within SAP, embedding directly into existing financial workflows rather than requiring separate portals or data exports. This keeps payment data inside SAP’s data model, reduces reconciliation effort, and maintains the compliance and audit trail requirements of SAP environments. Serrala’s payment solutions are built specifically for this architecture. You can learn more about Serrala’s payments automation capabilities here.
