The Hidden Economics of Custom IoT Applications
A Direct Challenge to Industrial IoT System Integrators
Industrial IoT integration has matured. Connectivity is no longer the hard part. Getting data to a cloud through an IoT or a remote access gateway is standard practice.
Yet, you collect data for a purpose and your customer still expects easily exploitable value out of it. Dashboards will give a good insight on business intelligence, but is that all your customer needs ?
This is when you step into application design... and life-long support.

You Built a Product You Didn't Intend to Build
When you developed that custom IoT application, you weren't just integrating systems. You were, whether you planned it or not, becoming a software company. You now own a codebase and a maintenance obligation. Every time your customer's process changes, every time a new sensor gets added, that's your phone ringing.
The initial development cost was visible. The ongoing cost isn't. Your best engineers context-switch between new projects and supporting old ones. Margins on the original job erode quietly...
But this application design is now where the value is created, because the basic dashboards & alarms, that are available by default, are not sufficient.
What Your Customer Actually Needed
What did your customer’s operations and maintenance team actually ask for? They wanted dashboards, but with a secured user access control. They wanted to know when a pump tripped. They wanted to log an intervention. They wanted calibration alerts, fault diagnostics, spare parts visibility, and the ability to understand last night's incident without calling anyone.
The traditional IoT platform ecosystem answered maybe 30% of that need. The rest required custom development. All of it bespoke. All of it yours to maintain. The industry became so focused on delivering business intelligence to management that it forgot the people standing next to the machine at 2am.
AGAD Portal Was Built From the Other Direction
AGAD Portal didn't start from an IT architecture and work downward. It started from a maintenance technician's field experience and worked upward. That's why the feature set looks the way it does : intervention and audit logging, calibration tracking, alarm management, spare parts stock, ANDON displays, fault investigation tools, real-time monitoring...
These aren't modules you build from scratch. They're ready on day one, which means commissioning overhead drops dramatically.
In one effluent plant case study, assessment, configuration, alarm setup, testing, and handover were completed in under a day. That's not the timeline of a custom build — it's the timeline of a platform designed to be deployed.
The Recurring Revenue You're Leaving on the Table
Every project delivered on a custom-built application is one where your customer relationship ends at go-live, except for the support calls you wish you weren't getting. No clean recurring revenue. No way to scale what you've built to the next customer without starting again.
With AGAD Portal, the relationship continues through the license. Maintenance contracts become a natural conversation. Expanding to new assets or sites is configuration, not redevelopment. You stop being a one-time vendor and become an ongoing service partner — with margin attached.
Because AGAD portal is already verticalized for Operations & Maintenance teams, the software part is already covered and you can focus on the value you create for your customer.
The Challenge
If you're already working with IoT or remote access gateways, you have the hard part solved. You can get data off the machine. The question is what you build on top of it, and whether that serves your business model as well as it serves your customer.
For most small and medium projects, custom development doesn't. The costs are disproportionate, the maintenance is a structural drag, and the result still doesn't give the maintenance team the practical tools they need.
There's a better way — and it's worth a conversation. It’s time to challenge the model.
