Custom Software Development

Software that works the way your business does.

Off-the-shelf tools force you to work around them. We build the opposite: internal tools, portals, CRMs and automations shaped exactly around how your team already operates — delivered fixed-scope, on a clear timeline.

Capabilities

What we build

If a spreadsheet, inbox or sticky-note system runs your business today, we can replace it with software that pays for itself.

Internal Dashboards & Admin Panels

Real-time visibility into sales, operations and fulfillment — one screen instead of five spreadsheets.

Client Portals

Give your customers logins to track orders, approve proofs, pay invoices and message your team — automatically.

SaaS & Product MVPs

Have a software idea? We scope the smallest valuable version, ship it fast, and iterate with real user feedback.

API Integrations

Your website, CRM, payments, email and spreadsheets talking to each other — no more copy-paste operations.

Workflow Automation

Quote-to-invoice, lead-to-follow-up, order-to-fulfillment — if your team repeats it weekly, we automate it.

Legacy Modernization

Outgrown WordPress hacks or an aging tool? We rebuild it cleanly — migrating your data without downtime.

The build

How we de-risk your project

Custom software has a reputation for blowing budgets. Ours doesn't — because scope, price and timeline are locked before kickoff, and you see working software every single week.

Week 1

Discovery & Scoping

We map your workflows on a free call, then deliver a fixed-scope proposal: exactly what we build, what it costs, and when you get it.

Week 2

Blueprint & UX

Wireframes and a clickable prototype of every screen — you approve the experience before a line of production code is written.

Weeks 3–8

Build Sprints

Weekly live demos of working features. You steer priorities as we go — no big-bang surprises at the end.

Launch

Launch & Handover

Deployment, team training, full documentation and 100% code ownership. Optional care plan keeps it fast and secure after launch.

Why RexTech

Built for businesses, not just browsers.

Fixed-Scope Pricing

The price we quote is the price you pay. Scope changes get quoted separately — never silently billed.

You Own the Code

Full source code, files and docs are transferred to you at handover. No lock-in, ever.

Weekly Live Demos

You watch your software come alive every week and steer priorities in real time.

Docs & Training Included

Your team gets trained on launch day, with written docs so anyone can run the system.

FAQ

Custom software, demystified.

Every build is scoped individually after a free discovery call. You receive a fixed-scope proposal — a set price and milestone timeline — before any work begins, so there are never surprise invoices.

Most small-business tools (CRMs, dashboards, portals) ship in 4–8 weeks from kickoff. Larger platforms are broken into phases so you start using the most valuable features first.

Yes. We routinely connect websites, CRMs, payment systems, email platforms and spreadsheets via APIs and automation platforms — your new software meets your business where it already lives.

You own 100% of the code, files and documentation. After launch we offer optional care plans covering hosting, monitoring, updates and new features — but you are never locked in.
