Open Source Payment Infrastructure Software
Payment Infrastructure software manages the technical systems required to process transactions, track subscriptions, and generate invoices. These tools handle usage metering and sales tax calculations to ensure accurate billing for digital products. This type of software serves developers and merchants who need to automate revenue collection. Self-hosting these apps allows you to process cryptocurrency payments and manage customer billing records without relying on external payment gateways or paying transaction fees to intermediaries.
