FlowSub

The platform handles the complexity that arises in subscription billing at scale: mid-cycle plan changes with accurate proration calculations, trial period management with automated conversion flows, usage-based billing that meters consumption and applies tiered pricing, and multi-currency billing for international customer bases with appropriate tax handling across jurisdictions.

FlowSub's dunning system proactively manages failed payment recovery the revenue preservation process that captures revenue that would otherwise be lost to expired cards, insufficient funds, and bank declines through intelligent retry scheduling, automated customer communication, and in-app payment update prompts.

Subscription analytics dashboards track the metrics that recurring revenue businesses depend on for strategic planning: monthly recurring revenue, annual recurring revenue, churn rate, net revenue retention, average revenue per user, and customer lifetime value calculated from actual billing data rather than estimates from separate analytics systems.

Revenue recognition automation produces the accounting entries required under ASC 606 and IFRS 15 revenue recognition standards.

SaaS founders building subscription products who need billing infrastructure without building it from scratch, finance teams at subscription businesses managing revenue reporting and recognition, and growth teams optimizing subscription conversion and retention metrics use FlowSub to handle the billing complexity that subscription businesses generate without the engineering investment that building compliant, scalable billing infrastructure requires internally.

The platform's developer-friendly API enables custom integration into product flows while pre-built dashboard tools serve the finance and operations stakeholders who need billing visibility without API access.
