ZEG Service

Software Built Around Your Business

The spreadsheet that runs your operation. The bookings you track by memory. The portal your clients keep asking for. We design, build, and deploy custom apps that replace the duct tape, on a modern stack, with a custom quote scoped to your project.

Real software, right-sized for you.

Every app is scoped to the problem it solves, built on the same modern architecture behind today's SaaS products, and deployed and maintained by the same team that built it. No handoffs, no abandoned codebases.

  • Clean billing handoff with exports that never leak rates

Built by the team that runs it after launch.

Most custom software fails after delivery, not during the build. An agency ships it, the invoice clears, and a year later nobody can update it. ZEG builds, deploys, hosts, and maintains every app we ship. It stays our problem, which is why we build it right.

Scoped Before Built

Every project starts with a consultation that maps what the app actually needs to do, what it should connect to, and what it should never try to be. You get a custom quote built from that scope. Feature creep gets caught in planning, not on your invoice.

Modern Stack, No Experiments

React, Next.js, managed databases, and enterprise cloud hosting. The same proven architecture behind the software you already trust, not a framework someone wanted to try. That means your app is fast, secure, and maintainable for years.

One Partner, Whole Picture

The same team building your app can run your website, your hosting, your automation, and your network. When your portal, your site, and your infrastructure share one owner, integrations get simpler and nothing falls between vendors.

Custom App Development FAQ

What counts as a custom app?
Anything your business needs that off-the-shelf software does not do well: client portals, internal dashboards, booking and scheduling systems, quote builders, order trackers, and tools that connect the systems you already use. If you are running your business out of spreadsheets and sticky notes, that is usually the sign.
How does pricing work?
Every app starts with a $200 AI and technology consultation where we scope exactly what you need. From there you get a custom quote for your project before any build work starts. Every app is different, so every build is quoted on its own scope. The consultation fee is credited toward any project over $1,000. No hourly meters, no surprise invoices.
Do you build mobile apps?
Yes. Most business apps work best as web apps that run on any phone and can be added to the home screen, so there is one app to maintain instead of three. When a project needs a true iPhone or Android app, we build that too, on the same backend, so the web and mobile versions always match.
What technology do you build on?
A modern, proven stack: React and Next.js on the front end, secure managed databases behind it, deployed on enterprise-grade cloud infrastructure. The same architecture powering modern SaaS products, sized for a small business budget.
Who maintains the app after launch?
We do. Every app ships with a managed hosting and maintenance plan so it stays fast, secure, and current. You are never handed a codebase and wished good luck.
Can the app connect to tools I already use?
Yes. Integrations with payment processors, calendars, email, CRMs, and most modern business tools are standard scope. Connecting your existing systems is usually where the biggest time savings come from.
How long does a build take?
Most small business apps launch in two to six weeks depending on scope. You see working previews during the build, not just at the end, so there are no surprises on delivery day.
