SaaS starter kit with authentication, payments and billing
Choose a React and TypeScript SaaS boilerplate with auth, subscriptions, credits and admin. Compare the Next.js and TanStack Start editions before buying source code.
Last updated: Oct 8, 2026
A SaaS starter kit gives you application source code for the work shared by subscription products: accounts, checkout, subscriptions, billing history and administration. ShipAny offers React and TypeScript SaaS boilerplates in Next.js and TanStack Start editions. Choose a framework foundation when you want to build your own product interface; choose an application template when its existing workflow already matches your idea.
What the SaaS boilerplate covers
| Requirement | Starting point | What you configure or build |
|---|---|---|
| Accounts | Sign-in, sessions and auth integration | Your OAuth apps, email settings and access rules |
| Payments | Checkout and payment-provider webhooks | Your merchant account, products, plans and credentials |
| Subscriptions | Subscription records and customer billing views | Your plan limits and cancellation policy |
| Usage credits | Credit grants, consumption, expiration and revocation | Your unit of usage and the price of each operation |
| Administration | Users, orders, settings and role permissions | Who may manage your product and what they may change |
| Localization | English and Chinese content and locale-aware routing | Your copy, translations and any additional languages |
The starter handles shared infrastructure. Your product-specific tables, workflows, validation and customer experience still need development. Provider accounts and hosting are separate from the template purchase.
Next.js or TanStack Start?
| Edition | Choose it when | Review before buying |
|---|---|---|
| ShipAny Next | Your team already uses Next.js and wants to keep that framework | The current framework version, demo and deployment requirements |
| ShipAny TanStack | You want TanStack Start with file routes, typed server functions and a React application | The route/data patterns and your intended Node or Cloudflare host |
Both editions expose the business code for customization. If your existing application uses another auth system or database model, plan the data migration before replacing it. A template purchase does not automatically migrate customer accounts or subscriptions.
A practical path to your first paid workflow
- Open the template's live preview and inspect the account, billing and admin screens.
- Read the documentation and license, then choose the edition that fits your team.
- Follow the edition's setup guide, connect a development database and configure authentication.
- Set up a payment provider in test mode and define a single plan or credit pack.
- Build one useful product operation and connect its access or usage limit to billing.
- Verify sign-in, checkout, payment confirmation, cancellation and failure handling before accepting live payments.

Questions before you buy
Is this a landing-page template or a full SaaS starter?
It includes backend business modules and account/admin interfaces as well as public pages. The framework editions are headless SaaS foundations: you design the main product experience around them.
Is the source code free or open source?
These are commercial templates with source-code access after purchase and activation. Source access is not an open-source license. Check the license for project use and redistribution terms.
Do I need Premium to get started?
Template detail pages show the available purchase options. Premium provides member benefits and member pricing; compare the current total cost of the membership and the templates you need.
Are ongoing costs included?
Hosting, database services, email, storage, payment-provider fees and AI API usage depend on your providers and traffic. Budget for those separately and test your paid workflow with real provider integrations.
