FastStar gives SaaS teams a complete billing stack — plans, trials, usage-based pricing, proration and dunning — and, as your seller of record, handles global tax compliance so you can focus on building the product.
Model any pricing: flat monthly or annual plans, per-seat pricing, usage-based and metered billing, free or paid trials, and add-ons. Mid-cycle upgrades and downgrades are prorated automatically so customers are always billed fairly.
Offer trials that convert automatically, recover failed payments with smart retries (dunning), and send proactive renewal reminders. Every billing event is delivered as a webhook, so provisioning and entitlements in your app stay perfectly in sync.
Selling software internationally means VAT, GST and US sales tax obligations that multiply quickly. In fully managed mode, FastStar calculates, collects and remits these as the seller of record across 90+ regions, so your finance team never chases overseas registrations or filings.
Integrate the hosted checkout with one line of our JS SDK, drive everything through a REST API covering payments, subscriptions, customers and payouts, and rely on event-driven webhooks for reconciliation. You never touch Stripe and never need a Stripe account.
Create a free account, integrate in minutes, and leave global payments and tax compliance to FastStar.
