Custom software development for processes that don’t fit off-the-shelf solutions.
When SaaS can’t bend to your reality, custom software bends to it. Inithex engineers bespoke web, desktop and mobile applications that operationalize your unique processes — built with modern stacks, secure by design, scalable to your growth, and engineered to be maintainable for the next 10 years.
Our development team has shipped over 50 production custom applications across B2B portals, internal operations tools, customer-facing platforms and SaaS products from concept to launch — using modern stacks (Node.js, .NET, Python, React, Vue, Next.js) and cloud-native deployment patterns.
Our technology stack
- Backend — Node.js (Express, NestJS), PHP (Laravel, Symfony), ASP.NET 8+, Python (FastAPI, Django).
- Frontend — React, Vue 3, Next.js, Nuxt 3, modern TypeScript, Tailwind, Radix UI.
- Databases — PostgreSQL, MySQL/MariaDB, SQL Server, MongoDB, Redis, ClickHouse.
- Cloud-native — Docker, Kubernetes (EKS/AKS/GKE), serverless (Lambda, Functions, Cloud Run).
- APIs — REST, GraphQL, gRPC, WebSockets, webhooks with idempotency and retry guarantees.
- DevOps — GitHub Actions, GitLab CI, CI/CD pipelines, infrastructure-as-code (Terraform, Pulumi).
- Observability — Sentry, Datadog, New Relic, OpenTelemetry instrumentation from day one.
What we build
- Custom B2B portals and customer self-service platforms (account management, order tracking, invoicing)
- Internal operations tools and back-office systems (workflow automation, approval flows)
- SaaS products from concept to launch (multi-tenant architecture, billing integration)
- Integration middleware connecting your stack (ESB, custom iPaaS)
- Embedded software for industry-specific hardware (IoT, kiosks, terminals)
- Migration of legacy systems to modern stacks (VB6 → React, Delphi → Vue, Access → cloud)
- Salesforce-adjacent applications (extending Salesforce with custom UI/UX where Lightning doesn’t fit)
Engineering principles we live by
Code is a liability, not an asset. Every line we write is a maintenance burden tomorrow. We optimize for clarity, testability and replaceability. Boring technology when possible (well-known, well-supported, hire-able), novel only when necessary. Test pyramid: more unit tests than integration tests than E2E. Documentation lives in the code (TSDoc, OpenAPI) so it doesn’t rot.
Frequently asked questions
Build vs buy — when does custom make sense?
Buy when SaaS solves 80%+ of your need at acceptable cost. Build when: (1) the process is your competitive differentiator, (2) SaaS pricing scales unfavorably with your usage, (3) integration with proprietary systems is required, or (4) data sovereignty/compliance requires on-premise. We always recommend SaaS first if it fits — custom is more expensive long-term to maintain.
How do you ensure code quality?
Mandatory code review (no direct-to-main commits), automated CI pipeline (linting, type checks, unit tests, integration tests), test coverage targets (>70% on critical paths), security scanning (Dependabot, SAST), and architecture reviews at design milestones. Clean code is non-negotiable in our team.
What happens if our team needs to take over later?
Knowledge transfer is part of every engagement: documented architecture, runbooks for common operations, recorded onboarding videos, code walkthroughs with your engineers, and 30-day handover period. Code is always your IP — we don’t lock you in.
How much does custom development cost?
Highly variable. A focused internal tool: USD $30K–$80K. A B2B portal with integrations: USD $80K–$200K. A multi-tenant SaaS MVP: USD $120K–$300K. Enterprise systems: USD $300K+. We always provide fixed-scope estimates after a 1–2 week discovery, with weekly updates and bi-weekly demos throughout build.
Do you offer fixed-price or time-and-materials?
Both, but we recommend fixed-price for well-defined projects (clearly scoped MVP, defined integrations) and time-and-materials for exploratory work (innovation projects, R&D phases). We never bill by hour without weekly visibility into spend.
