Payment Processing Software
Updated August 2026 · By the ERP Research Editorial Team · Independent and vendor-neutral — no vendor pays for placement or ranking.
Payment processing software authorizes, captures and settles card, ACH and digital-wallet payments on behalf of a business, then moves the funds and transaction data into its accounting system. For B2B teams billing invoices rather than running a retail checkout, the priority shifts from consumer checkout conversion to interchange cost, ACH/eCheck support, Level 2/3 card data for lower fees, and a clean reconciliation trail.
This guide compares the leading payment processing platforms on what matters for B2B and ERP-connected finance teams: fee structure and rate model, ACH and card acceptance depth, PCI compliance handling, and, since a processed payment is only useful once it posts to the books, how cleanly each one syncs into your ERP or accounting system as the system of record.

Certified = listed on the ERP vendor's official marketplace. Prebuilt = productised vendor-built connector. iPaaS = official integration-platform template. API = integration is possible via documented APIs but no productised connector was evidenced. A dash means we found no evidence — not that no integration exists.

Payment processing software is the layer that authorizes a card or bank-debit transaction, routes it through the card networks or banking rails, and settles funds into a business bank account, while handling PCI-compliant storage of payment credentials. Consumer-facing processors optimize for checkout conversion and one-off retail sales; B2B-focused processors instead optimize for invoice-based payments, ACH and wire acceptance, surcharging and Level 2/3 card data that reduces interchange on business-to-business transactions. Most established platforms also offer tokenization for recurring/card-on-file billing, a merchant or virtual terminal for phone and manual payments, and settlement reporting. The category overlaps with AR automation and billing software, but a dedicated payment processor's core job is authorization, settlement and compliance, not invoicing or dunning workflow.
How to choose payment processing software
B2B fee structure
Interchange-plus pricing and Level 2/3 card data support materially cut cost on business-to-business card transactions versus flat consumer rates.
ACH and eCheck acceptance
B2B buyers often prefer bank debit over cards; confirm ACH support, return handling and same-day options, not card-only acceptance.
PCI compliance and tokenization
The processor should carry PCI DSS Level 1 certification and offer tokenization so card data never touches your own systems.
ERP / accounting sync
A certified, bi-directional connector that posts settled payments, fees and reconciliation detail straight into NetSuite, SAP, Dynamics 365, Sage or Acumatica.
Surcharging and cash discounting
Where legal, the ability to pass card fees back to the payer changes the effective cost of accepting cards for B2B invoicing.
Global currency and payment method coverage
If you invoice across borders, confirm supported currencies, local payment methods and settlement countries before shortlisting.
Payment Processing that works with your ERP
A payment processor that is not wired into your ERP just creates a second ledger to reconcile by hand. The strongest options in this category post settled payments, processing fees and chargebacks directly into NetSuite, SAP, Dynamics 365, Sage Intacct or Acumatica with the correct GL coding, instead of leaving finance to match a settlement report against open invoices line by line. That ERP connector, more than the headline processing rate, is usually what determines whether a payment platform actually reduces close-time work. Every product below is profiled with the ERPs it documents a real integration for.
Frequently asked questions
What is the best payment processing software for B2B companies?
The best payment processing software for B2B invoicing depends on your ERP and payment mix. Teams that need ACH and Level 2/3 card-data support for lower interchange typically look at processors and ERP-embedded connectors built for business payments, rather than consumer checkout platforms. Compare the options below by ERP fit, ACH support and fee structure rather than by brand alone.
How much does payment processing software cost?
Pricing usually combines a per-transaction fee (often 2.5-3.5% for cards, lower for ACH) with either flat-rate or interchange-plus pricing; interchange-plus with Level 2/3 data typically costs less for B2B card transactions. Some ERP-embedded platforms are quote-based. Each product profile below lists the vendor's published pricing model where available.
Does payment processing software integrate with my ERP?
Many established payment processors and ERP-embedded payment vendors connect to NetSuite, SAP, Microsoft Dynamics 365, Sage and Acumatica, either through a native SuiteApp/plugin or a certified connector, posting settled payments and fees back to the general ledger. Integration depth varies a lot by vendor, so confirm support for your specific ERP and version before shortlisting; each profile below notes the ERPs it connects to.
What is the difference between payment processing and a payment gateway?
A payment gateway captures and encrypts card or bank details at checkout and passes them on for authorization; a payment processor is the company (often working with an acquiring bank) that actually authorizes, clears and settles the transaction. Many vendors in this category, including the ERP-embedded ones, bundle both roles into a single platform, which is why the terms are often used interchangeably in buying guides.
What features should B2B payment processing software have?
Look for interchange-plus pricing with Level 2/3 card data, ACH/eCheck acceptance, PCI DSS Level 1 compliance with tokenization, surcharging or cash-discounting support where legal, and a bi-directional ERP or accounting sync.
