Processing payments online requires more than just a checkout button. Payment processors handle transaction routing, authorization, and settlement across cards, bank transfers, and digital wallets – ensuring funds move securely between customers and businesses. Platforms in this space manage PCI compliance, fraud detection, and chargeback resolution, removing much of the operational burden from merchants. Many support recurring billing, currency conversion, and integrations with ecommerce, invoicing, or accounting systems. Real-time dashboards, payout scheduling, and granular reporting give teams control over cash flow and reconciliation. With global reach and support for multiple payment methods, these tools form the financial backbone for digital commerce and subscription businesses.
