SaaS Billing Development for Stripe Subscriptions

The right model aligns your price with the value customers receive. Per-seat works when value scales with team size (e.g., Slack). Usage-based works when value scales with consumption (e.g., Twilio). Flat-rate works for simple products with a clear value proposition where complexity would harm conversion. Many successful SaaS products combine models — a flat platform fee plus per-seat or usage charges.

Stripe is the most powerful and developer-friendly, ideal for technical teams who want full control. Paddle is a Merchant of Record — they handle VAT/sales tax globally, reducing compliance overhead, great for bootstrappers and small teams. Chargebee is a subscription management layer on top of Stripe/Braintree with more out-of-the-box revenue reporting — useful at scale when you need robust MRR analytics without building them yourself. We work with all three.

Stripe Tax can automatically calculate and collect VAT/GST for most countries. For simpler global tax compliance, Paddle as Merchant of Record handles all tax liability. We configure your billing stack for the markets you're targeting, with proper tax ID collection for B2B customers in the EU who need VAT-exempt invoices.

We recommend collecting payment details upfront (card required to start trial) — this is proven to increase trial-to-paid conversion by 2-3x and reduces involuntary churn. The trial is configured in Stripe with a trial_end date and automatic charge on conversion. We build in-app prompts that surface upgrade CTAs as the trial end date approaches.

Stripe handles proration natively — when a customer upgrades mid-cycle, they are charged the pro-rated difference immediately. For downgrades, we typically credit the difference to the next invoice. We implement a preview-before-confirm UI so customers see exactly what they will be charged before they confirm a plan change, reducing support tickets and disputes.
