Invoice Template for React Developers

React developers bill across component, integration, and performance categories. Component Development covers building reusable React components with prop interfaces, TypeScript types, and Storybook documentation. State Management refers to implementing global state with Redux Toolkit, Zustand, or React Context, including store structure design and selector patterns. API Integration covers consuming REST or GraphQL APIs using React Query, SWR, or Axios, with loading states, error boundaries, and cache invalidation. Performance Optimisation captures profiling and fixing performance bottlenecks — lazy loading, memo, useMemo, and virtualised lists. Testing covers writing unit tests with Vitest or Jest and component tests with React Testing Library.

React developers price hourly ($70–$180/hr) for most client work because the scope is rarely fully defined at the start. Project-based pricing works for well-scoped features or standalone component libraries ($1,500–$8,000). Monthly engineering retainers (40–80 hours) suit companies building continuously. Storybook or design system work is often a separate fixed-price engagement. Front-end-only React is priced lower than full-stack work — be clear about scope in your contract.
