Payment processing software helps businesses securely handle and track business-to-business (B2B) payments from customers and to suppliers. It supports any organization that accepts non-cash payments by ensuring transactions are timely, accurate, and integrated with downstream financial systems.

### Core Capabilities of Payment Processing Software

To qualify for inclusion in the Payment Processing category, a product must:

- Collect customer payment information and relay it to a bank for approval or denial
- Transmit approval or denial of a transaction back to the customer or merchant
- Support multiple payment methods such as credit card, ACH, or wire transfer
- Define and track customizable payment rules, terms, and deadlines
- Identify errors such as late payments, overpayments, or failed transactions
- Integrate with ERP, accounting, or accounts receivable and accounts payable systems

### How Payment Processing Software Differs from Other Tools

Payment processing software focuses on secure transaction handling and status verification, working closely with related tools such as [payment gateways](https://www.g2.com/categories/payment-gateways), [accounting software](https://www.g2.com/categories/accounting), [AP automation software](https://www.g2.com/categories/ap-automation), [e-commerce platforms](https://www.g2.com/categories/e-commerce-platforms), and [retail POS systems](https://www.g2.com/categories/retail-pos). Its distinguishing value lies in managing payment execution and error identification across diverse payment methods.
