ChaChing

The analytics dashboard provides real-time revenue metrics including MRR, ARR, LTV, churn, and growth trends, all displayed in high-fidelity charts. Users can visualize cohort health and identify at-risk revenue before it disappears. For developers, ChaChing offers a fully documented OpenAPI architecture, a testing sandbox for safe iteration, and a Stripe migration toolkit that enables zero-downtime migration of customers, subscriptions, and tax rates. The platform also includes a hosted payment page and customer portal for managing billing details. This combination of analytics and developer tools ensures teams can both monitor business health and integrate billing seamlessly into their existing tech stack.

ChaChing works as a replacement for the Stripe billing layer while retaining Stripe for payment processing. Users start by connecting their Stripe account, then select which subscriptions to migrate via a simple three-step process: connect, select, review. The platform automatically imports customers, subscriptions, and dependencies, and replaces Stripe's hosted pages with its own. Once migrated, all billing logic—including cycles, prorations, retries, and tax calculations—runs through ChaChing's engine, which is built on the open-source Kill Bill core. This architecture ensures transparency, as the codebase is fully auditable, and prevents vendor lock-in by allowing businesses to run Kill Bill independently if they outgrow ChaChing.

A growing SaaS startup can migrate from Stripe Billing to ChaChing in minutes, immediately reducing their billing fees from 0.7% to 0.35% and saving thousands annually. An e-commerce business selling digital goods can leverage the pluggable tax engine to ensure compliance with multi-state sales tax laws without manual effort. A subscription box service can use automated proration and smart retries to handle failed payments and upgrades seamlessly, reducing churn and improving customer satisfaction. The real-time analytics dashboard gives founders and finance teams a clear view of MRR trends and customer lifetime value, enabling data-driven decisions. These concrete outcomes demonstrate how ChaChing transforms billing from a cost center into a strategic advantage.

ChaChing is designed for startup founders, finance managers, SaaS developers, and enterprise procurement teams who need a cost-effective, transparent billing solution. It works with any business using Stripe for payment processing, particularly those with subscription models or recurring invoices. Pricing is simple: 0.35% of billing volume for startups and SMBs, with custom enterprise plans available. The platform is built on Kill Bill's open-source core, ensuring no lock-in and full data portability. In summary, ChaChing offers a compelling Stripe billing alternative that reduces costs, simplifies tax compliance, and provides powerful analytics, all while maintaining the reliability of the payment processor businesses already trust.
