ZENNEX Consulting

Custom software that fits how your business runs.

Portals, internal tools and integrations that replace spreadsheets and copy-paste. Built in fixed-price stages by senior engineers, and you own every line.

Big software projects run over. Ours ship in small pieces.

Large IT projects overrun because nobody wrote the scope down and everything waits for one big launch. We fix scope and price first, release something useful early, and keep the same engineers on it throughout.

What you get.

Software that removes one expensive problem first, then grows once it has proved its worth.

Outcome 01 of 06

A portal customers use themselves

Customers check orders, download documents, raise requests and pay without emailing your team.

What’s included

  • Secure sign-in and role-based access
  • Orders, documents and invoices in one place
  • Requests and payments handled online
  • Works on any phone or browser

How you’ll know it’s working

Fewer "where's my order?" emails and phone calls, and customers serving themselves.

How it works.

A fixed price for each stage. Nothing is built until you've agreed it in writing.

  1. 01

    Discovery

    We sit with the people who do the work and map where time and money are lost.

    You get

    A written scope and a fixed price.

  2. 02

    First useful release

    The smallest version that removes real work, usually within four to eight weeks.

    You get

    Software your team uses in production.

  3. 03

    Fortnightly cycles

    A working demo every two weeks. You can change priorities between cycles.

    You get

    Progress you can click through, not a status report.

  4. 04

    Hand over or keep going

    We support it on a monthly plan, or hand it to your own team.

    You get

    Source code, documentation and every account in your name.

Is this right for you?

A good fit if

  • A process runs on spreadsheets, email and copy-paste
  • Your systems don't talk to each other
  • Off-the-shelf software fits 80% and the other 20% costs you every week
  • You want to own the code, not rent it

Not what we do

  • Building software an existing product already does well; we'll tell you which one
  • Open-ended projects with no agreed outcome
  • Large teams of junior developers billed by the hour

Questions we get asked.

How much does custom software cost?

It depends on scope, which is why we price after discovery, not before. You get a fixed price for each stage in writing, so the budget can't drift without you agreeing to it.

Who owns the code?

You do. The source code, repositories, cloud accounts and documentation are in your name from the start, so you can take the work to another team at any time.

Should we build or buy?

Buy if a product already does the job well; it's cheaper and someone else maintains it. Build when the process is what sets you apart, when you're paying for several tools to do one job, or when the workarounds cost more than the software would. We'll give you an honest answer in discovery, even if it's "buy".

What technology do you use?

Mostly TypeScript, React, Next.js and Node.js, with PostgreSQL or MongoDB, hosted on AWS or Vercel. These are widely used, well documented and easy to hire for, so you're never locked in to us.

Can you work with our existing systems?

Yes. Most of what we build connects to software you already use: CRMs, accounting, ERPs, ecommerce platforms and payment providers. If it has an API, we can usually integrate it, and if it doesn't, we'll find another way in.

What happens after launch?

We monitor it, keep dependencies and security patches up to date, and make small improvements on a monthly plan. Or we hand everything to your team with documentation they can follow.
