Custom software

The intelligent system that runs your company.

From your customer's click until they receive what they ordered, with AI agents deciding and executing every step. We don't bend your company to fit a program: we build the system around it.

From the office to the shop floor ERP, CRM, apps and portals. And the PLC on the machine, too.
The code is yours Written from scratch for your company. No per-user licence.
Who builds it The Nexus team, in person. No juniors, no subcontractors.

An order comes in through one place and someone retypes it into another. Between one program and the next there's always a person acting as a bridge, and when that person is off, the chain stops. It never shows up in your P&L, but you pay for it every month.

A single event
sets everything else in motion.

The order comes in

Your customer buys, signs or requests. That single event starts the whole chain, without anyone copying it somewhere else or phoning anyone.

AI decides and assigns

An agent decides what needs to happen, in what order, and who or what does it. It prioritises with your criteria and your margins, not those of a generic manual.

It runs wherever it needs to

The end of the chain is yours: a CNC machine, a robotic arm, a warehouse, an accounting firm, a supplier or simply the screen of someone on your team.

And it's all recorded

Every step leaves a trace. You know where any job stands, what it has cost and where it gets stuck, without asking anyone.

The full chain is how far we can go, not the minimum we start with. If what you need is an internal application, a mobile or desktop app, an ERP or CRM built around you, a customer portal, PLC programming so your machines talk to each other, or two programs that ignore each other starting to talk — we build that too.

Any software, literally

From the office to the shop floor.

Business software

What moves paperwork, data and decisions.

  • ERP and CRM built on the way you actually work
  • Invoicing, back office and dashboards
  • Customer and supplier portals
  • Mobile and desktop apps for your team
  • Integrations between the programs you already use

Industrial software

What moves machines, parts and pallets.

  • PLC and controller programming
  • Machines that talk to each other — CNC, robots, conveyors
  • Logistics and warehouse management
  • Shop-floor records: what was produced, when and at what cost
  • The bridge between the shop floor and the office, in one system

If your company needs it and it doesn't exist, we build it. And if it exists but doesn't talk to anything else, we connect it.

Everything is written from scratch for your company, so the code is yours: full ownership, with no per-user licence and no one's permission needed to touch it. If one day you want to continue with another team, you take the whole system with you.

Before you decide

What you replace and what you take on.

What you gain

  • The order comes in once and travels through the whole company without anyone retyping it
  • Each step starts on its own when the previous one finishes, without anyone having to chase it
  • You know where any job stands without asking anyone
  • You know which customer and which product leave you a margin, without building a spreadsheet

What it will demand from you

  • Opening up your internal costs, your margins and your prices per customer
  • Your team will work with two systems at once while we switch off the old one
  • The exceptions that today live only in someone's head have to be documented
  • It's the most expensive thing we do and the slowest to show results
