Use Cases
A SaaS startup launches a Pro plan with 14-day trials and monthly cycles. Using this skill, the team designs subscription states (trial→active→past_due), implements proration for mid-cycle upgrades, and generates invoices automatically. It prevents revenue leakage and saves engineering time on billing logic.
An existing platform sees rising failed payments. The skill's dunning management patterns help configure retry schedules, grace periods, and customer notifications. Automated recovery restores cash flow and reduces manual chasing by the finance team.
