Open Source Subscription & Billing Management Software
Subscription & Billing Management software automates the process of tracking recurring payments and generating invoices for digital services. These tools handle usage-based metering and credit systems to ensure customers pay for the exact amount of resources they consume. This type of software is for SaaS founders and hosting providers who need to manage revenue analytics and sales tax without relying on proprietary payment platforms. Self-hosting these apps allows you to keep sensitive payment histories and customer billing cycles on your own infrastructure.
