- 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
