Treevoxa is a React development company, a ReactJS development company in plain terms, for teams that need interfaces people use all day: dashboards, point-of-sale screens, SaaS front ends, customer portals, and fast Next.js websites that search engines can read. We write TypeScript, we build the APIs behind the screens, and we put the scope and the price in writing before we start.
What we build with React
- SaaS front ends: sign-up, onboarding, settings, billing and the product itself.
- Dashboards and back-office screens with tables, filters, charts and bulk actions.
- Point-of-sale and data-entry screens built for speed on a keyboard and a scanner.
- Customer portals for orders, documents, payments and support.
- Next.js websites and stores that render on the server and load fast on a phone.
What makes a top ReactJS development company
Not the number of logos on its site. Ask any React development company in the USA or elsewhere to show you interfaces it built that people use all day, then ask how it handles slow tables, forms with complex validation, and state that must stay in step with the server. Ours are public:
React in our own products
- PharmaFlow has a React point of sale and admin built with Vite, TanStack Query and TanStack Table, React Hook Form, Radix UI and Tailwind CSS, with charts, drag-and-drop and maps, plus a Next.js public site.
- RE-ERP has a Next.js web app with Zustand state, Recharts reports and QR codes.
- MatrixHR has a Next.js web app sharing types with its NestJS API.
- DealWisp has a React front end with TanStack Query, Radix UI components and React Hook Form with Zod validation.
React and Next.js
Next.js renders pages on the server, so visitors and search engines get real HTML quickly. We use it for marketing sites, documentation, stores and public portals, and for apps that mix public and logged-in pages. See Next.js development services for server-rendered sites, and React Native app development for mobile.

How a React project runs
- Discovery. Who uses each screen, how often, on which device, and what slows them down today.
- Prototype. The key screens, clickable, tested with real users.
- Written scope. Screens, integrations, milestones and the price.
- Build in short cycles. A staging site to log in to every one or two weeks.
- Launch and support. Performance checks, accessibility checks, monitoring and a support agreement.
Engagement models for React work
- Fixed scope for a defined app or site.
- Dedicated React developer working only on your product, billed monthly. See hire developers.
- Hourly for audits, fixes and small features.
What React development costs
A React project's cost depends on the number of distinct screens, the complexity of tables and forms, whether the API exists, and how much design work is needed. The custom software development cost guide explains the drivers, and developer rates compares what teams charge. We quote in US dollars, in writing.
React pitfalls we avoid
- State everywhere. Server data lives in a query cache, not copied into components, so screens stay in step with the server.
- Slow tables. Large lists are paginated or virtualised, and filters run on the server.
- Forms that lose work. Validation runs as you type, and drafts are kept when a page reloads.
- Inaccessible components. Accessible primitives for menus, dialogs and selects, so keyboards and screen readers work.
What to send us for a React quote
Who uses each screen and how often, any designs you have, the API it talks to, and two or three apps whose interfaces you admire.
Working across time zones on React projects
We agree a daily overlap window in your working hours before the project starts, usually your morning for US teams and the afternoon for UK and European teams. A new staging build is usually waiting when your day starts.
