Welcome

Welcome to the business section of the ProAbono documentation.

Here you will find everything you need to understand the economic, legal and operational mechanics of subscription management in a SaaS model.

Whether you are designing your offer, structuring your billing, or looking to optimise your metrics, this section helps you to:

• Decode the fundamental concepts: calendar billing, proratization, deferred income, grandfather clause…
• Choose a suitable pricing model: freemium, tiered pricing, tiered vs. volume pricing…
• Track the right SaaS KPIs: ARR, churn, LTV, ARPU, CAC…
• Understand compliance and payment topics: PSD2, GDPR, PCI DSS, payment methods…

Our goal: help you make the right business decisions, and speak the same language as your developers, your CFO or your billing solution.
