Project details
You will get a production-ready Stripe integration built into your .NET application by a UK developer with 8+ years of experience and 100% Job Success on Upwork.
Most recently shipped the full Stripe billing layer for Chronicle, a UK workforce management SaaS. That covered Checkout, Subscriptions, Customer Portal, webhooks and the full subscription lifecycle including upgrades, downgrades and prorated billing. Happy to share a short Loom of it running before you buy.
What separates this from a quick Stripe wire-up is how the database mapping and webhook layer get treated. Payments break in subtle ways months after launch, things like failed renewals, race conditions and duplicate invoices. Getting the foundation right is what stops 2am support calls later. Every flow gets validated with Stripe Test Clocks before going live, so trial endings, renewals and dunning are proven to fire correctly rather than hoped for.
Comfortable across .NET Framework, .NET Core, Blazor Server, ASP.NET MVC, Web API and SQL Server or PostgreSQL.
