what is awesome-billing fr?

Awesome-billing is a curated collection of resources designed to help software teams build billing and payments systems. Instead of providing code or a downloadable tool, it serves as an organized reading list covering everything from pricing strategies and invoicing to accounting, fraud detection, and business intelligence. It is essentially a reference library for anyone who needs to figure out how to charge customers and manage money within a software product. The collection is organized into categories that walk you through the entire billing lifecycle. You will find sections on choosing a pricing model, whether that is a monthly subscription, usage-based metering, or a hybrid approach. Other sections dive into the mechanics behind the scenes: how to structure invoices, handle multiple currencies, calculate taxes like European VAT, manage product catalogs, and process payments via credit cards or bank accounts. There are also dedicated areas for detecting fraud, designing the customer-facing billing UI, and analyzing metrics like customer lifetime value. This resource is aimed at engineers, product managers, and founders building software that needs to collect money, especially SaaS or cloud platforms. For example, if you are launching an AI product and want to charge customers based on how much they actually use it, the usage-based pricing section links to articles on why that model works, open-source billing engines, and deep dives into the math of quantifying usage. If you are trying to figure out how to price a niche product, the market research section points to survey methods and pricing psychology guides to help you find the right number. What makes this project notable is its sheer breadth and the philosophy behind it. Billing is notoriously difficult because it sits at the intersection of software, business logic, and financial compliance. Rather than pointing to a single tool that solves everything, the list acknowledges that billing is a complex domain requiring knowledge across many disciplines. The curated links range from practical engineering advice to academic papers on cloud resource pricing, giving readers a grounding in both the how and the why of building billing systems.
