Custom software for businesses, connected to AI
Custom software is a tool built exactly for the way your business works, instead of bending to a generic program. Nertel designs and builds customer portals, internal tools and applications, and connects them to your voice and WhatsApp agents and to the tools you already use.

How it works inside
How it fits with the rest of your business
Each piece does one job and hands over to the next, just like an automation workflow. Here’s how yours works, step by step.
- Trigger: Customer request (Agent or portal)
- App: Your application (Custom-built)
- Action: Database (Customers, orders)
- Action: Internal dashboard (For your team)
- Action: AI agent (Built in)
- Action: Notifications (Email and WhatsApp)
What it does
What we build for you

Portals for your customers
A space where customers check orders, bookings or documents without having to call.
Internal tools
Dashboards, records and workflows built around your day-to-day work, instead of spreadsheets.
With built-in AI agents
The voice or chat agent lives inside the tool, just as Nertus lives inside this page.
Connected to what you already use
Your new software talks to your CRM, ERP, calendar or invoicing, with no duplicate data.
Works on every screen
Designed for mobile, tablet and desktop, and fast on all of them.
How it works
From the first conversation to up and running
You tell us how you work
By phone, in writing or by talking to Nertus on this website: who your customers are, what they ask for and how you handle it.
We build it around you
The Nertel team configures it with your company’s information and connects it to the tools you already use.
Working from day one
It is usually serving customers within one to two weeks. Whenever something changes in your business, it is updated.

Questions
Frequently asked questions
What is custom software?
It is software built specifically for one business: it does what that business needs, the way it needs it, and connects to its tools. Unlike generic software, it doesn’t force you to change the way you work.
Can an AI agent be built into an application?
Yes. The agent looks after whoever uses the application, answers their questions and leaves the details in your tools, just as Nertus does on this page.
When is custom software not worth it?
If off-the-shelf software already covers what you need and doesn’t have to connect to anything else, it’s the best option. Custom software pays off when a process is unique to your business or when the tools you use don’t talk to each other.
