How Do B2B Payments Work?

A B2B payment usually follows an agreed purchase, contract or invoice. The buyer pays through a bank transfer, card or another method accepted by the seller. Both businesses then need to match the payment to the correct invoice or order in their records.

Payment terms can affect when the money is due. For example, a supplier may require payment at checkout or give the buyer a set number of days to pay an invoice.

Common B2B Payment Methods

• Bank transfers: Used for invoices and supplier payments. In the UK, businesses may use Faster Payments, Bacs Direct Credit or CHAPS, depending on the payment’s timing and requirements.
• Business cards: Used when a supplier accepts card payments, including online purchases and recurring services.
• Cheques: Still accepted in some business relationships, although they require more manual handling than electronic methods.

A business may use several methods because paying a supplier’s invoice and accepting an online card payment involve different processes.

When Is a Payment Gateway Used for B2B Payments?

A business can pay a supplier’s invoice by bank transfer or pay for software with a business card at an online checkout. Both are B2B payments. A payment gateway may be involved in the online checkout, while a direct bank transfer generally follows a separate process.

A B2B payment gateway helps the seller accept online payments and connects the checkout to payment processing services. It does not replace invoicing, internal purchase approvals or the systems a buyer uses to pay suppliers. That distinction helps businesses choose tools for the payment flow they actually need.
