The challenge
Where teams get stuck
The problems we're most often brought in to solve.
- 01
Failed payments drive silent churn
Cards expire or decline and customers are lost with no dunning emails, retries or grace period to recover payment.
- 02
Plan changes require manual effort
Upgrades, downgrades and refunds need support staff to adjust records by hand, creating delays and billing errors.
- 03
Entitlements and billing drift apart
Customers retain features after cancelling, or lose them after paying, because application and billing are not synchronised.
Overview
Subscription & Billing Platforms at VulcanTech
A subscription billing platform manages recurring charges, plan changes and entitlements for a subscription business. VulcanTech implements billing that handles the edge cases early-stage products get wrong: proration on plan changes, dunning for failed payments, seat-based and metered pricing, and self-service upgrades and cancellations. Billing events synchronise with your application through webhooks, so entitlements and invoices always reflect each customer's actual plan.
Key deliverables
- Stripe or Paddle subscription integration with webhooks
- Proration, upgrade, downgrade and cancellation flows
- Dunning management for failed payments
- Customer billing portal
- Subscription reporting views
