6 Best B2B Payment Processing Companies of June 2025
B2B payment solutions should have affordable processing rates, integrate with your accounting software and offer detailed invoicing features.
Business-to-business (B2B) payment processing companies handle transactions between businesses, and the best options help streamline the process with recurring invoicing, security tools and, in some cases, approval workflow automation. Since B2B payments can be larger than typical business-to-consumer (B2C) transactions, some B2B payment processing companies also extend lower processing rates.

What are B2B payments?
B2B payments refer to transactions between businesses. Since these transaction amounts can be large and the exchange may involve contracts, sales aren’t usually completed as instantaneously as they are for B2C (business-to-consumer) companies. In contrast to B2C payments, which are typically completed in-store at a point-of-sale (POS) register or online through an e-commerce site, B2B payments are often sent via invoice and may be recurring. In general, the business on the purchasing end can choose to pay invoices with a check, ACH transfer or card.

How much do B2B payments cost?
B2B payment processing costs include transaction fees and may also come with a subscription fee. The two main types of B2B payment processing models are flat-rate and interchange-plus.
Flat-rate payment processing companies charge the same flat rate per transaction, regardless of interchange rates, and companies that offer both B2C and B2B payment processing services may charge the same rates for each kind of transaction. For example, Stripe
On the other hand, interchange-plus and subscription-based payment processors, which pass interchange savings to the merchant, can usually offer a bit more flexibility. Under these pricing models, B2B businesses may be able to access lower interchange fees
How to choose the best B2B payment processor
To pick the best B2B payment processing company for your business, consider the following factors.
Payment processing cost
How much you pay to process B2B payments largely depends on your payment processing company’s pricing model. Flat-rate processing is easy to understand, but can be expensive if you process a high volume of transactions. Alternatively, interchange-plus pricing can be more cost-effective, but less predictable.
For example, online transactions processed through Helcim Square
Additionally, consider which kinds of payments you accept most frequently. If you rarely accept credit card payments
Accepted payment types
Make sure your B2B payment processing company accepts all the payment types your clients typically use. Those could include credit cards, debit cards, ACH transfers, wire transfers, cash and check payments.
Industry specificity
If your business processes a high volume of transactions and mainly works with other businesses, instead of consumers, an industry-specific B2B product, like Paystand, can help you implement invoicing workflows and save on processing fees. If your clients include both businesses and consumers, though, a more generalized payment processor, like Square or Stripe, could be a better option.
Invoicing tools
Since B2B payments are often larger than typical B2C transactions, it’s common to send invoices and offer clients a payment plan. If this is the case for your business, your payment processor should double as an invoicing software
Integrations
At a minimum, your B2B payment solution should integrate with your accounting software
