The Hidden Cost of Juggling Multiple Supplier Portals

By Peregrin Team

Every HVAC controls contractor deals with multiple supplier portals. Here's how that fragmentation is costing you more than you think.

The Portal Problem

You work with Honeywell. And Johnson Controls. And Tridium. And maybe Distech, Belimo, or Schneider Electric too. Each one has their own ordering portal, their own login, their own way of searching for parts, and their own format for invoices and confirmations.

You’ve gotten used to it. But getting used to something doesn’t mean it isn’t costing you.

Context Switching Is Expensive

Every time someone on your team switches from one supplier portal to another, they lose momentum. They have to remember different interfaces, different search behaviors, different workflows. Research shows that context switching can cost up to 40% of productive time. In procurement, that translates directly to slower order processing and more mistakes.

No Single Source of Truth

When your purchasing data lives in six different supplier portals plus a spreadsheet plus an email inbox, there is no single place to go for answers. Where’s that shipment? What did we pay for that part last time? Did we already order the controllers for the downtown project?

These questions should take seconds to answer. Instead, they take minutes or hours of digging through different systems. And sometimes the answer is simply “I don’t know,” which leads to duplicate orders, missed deliveries, and wasted money.

The Comparison Problem

When you need to source a part, how do you compare options? You open one portal, search for the part, note the price and availability. Then you open another portal and do the same thing. Maybe a third. By the time you’ve checked three or four suppliers, you’ve spent twenty minutes on what should be a thirty-second decision.

And let’s be honest: most of the time, you don’t bother comparing. You go with the supplier you usually use because checking alternatives takes too long. That convenience comes at a cost.

One Platform, All Your Suppliers

The solution isn’t to consolidate down to one supplier. Your supplier relationships are valuable, and different suppliers serve different needs. The solution is to bring all those suppliers into one platform where you can search, compare, order, and track without switching between systems.

That’s the core idea behind Peregrin. One platform that connects to all of your suppliers, gives you a unified catalog, and eliminates the context switching, duplicate data entry, and visibility gaps that come with portal juggling.
