> Incumbent suppliers have the executives locked up, but managers are still shopping around, and that’s exactly where a challenger gets in.

If you’re trying to take business away from an entrenched supplier, the executive who already trusts them is the wrong place to start. Start with the manager still running a real evaluation, then give them what they need to carry it upward.

Here’s the data behind it.

## **Executives Default to the Incumbent. Managers Don’t.**

The Summer 2026 Industrial Buyer Pulse asked what happens when a new need comes up in a category where a buyer already has a supplier. Among C-level and VP buyers, 61% say the incumbent usually or almost always wins with no competitive evaluation at all. Among managers, that number is 34%. Executives are nearly twice as likely as managers to let the incumbent win without a look.

Asked how their sourcing strategy has shifted over the past year, 49% of C-level and VP buyers report consolidating to fewer, deeper supplier relationships. Only 12% of managers say the same. Managers are moving the other way. 54% of them, more than any other response, added backup suppliers instead, widening their base.

Put the two together and the picture is simple. Executives have already made a strategic call to concentrate spend with suppliers they trust, and an incumbent is the automatic winner of that call. Managers are still making that call, actively running the kind of open, competitive evaluation a challenger needs to exist.

## **The Incumbent’s Advantage Is Concentrated at the Top**

This is the part most account-based programs get backwards. Sales and marketing effort often defaults to the highest title on the org chart, because that’s where the budget authority sits. However, the data says that’s the buyer least likely to run an evaluation you could win. The manager is where a genuine contest is still happening, and it’s the buyer most programs deprioritize in favor of chasing the executive signature.

The executive still deserves attention, just a different kind. An executive relationship with an incumbent is a strategic decision that only breaks when the incumbent fails. Three in five buyers have replaced a primary supplier in the past six months specifically over delivery, quality, or reliability failures. That’s the moment an account reopens, and that’s where senior-account effort belongs, watching for the failure and being ready when it happens, rather than trying to force an evaluation open before it does.

## **Where Getting In Through the Manager Starts**

Industrial buyers were also asked what gets a supplier cut before any conversation happens. They named missing certification or compliance documentation first, 28%, ahead of negative reviews at 23% and a slow or generic response to an inquiry at 18%. A thin or outdated website barely factors in at 6%. Whatever else a manager is comparing suppliers on, documented proof is what clears the first cut.

So have that proof ready before the comparison starts, and build it for the person actually running it. An engineer, a technical buyer, an operations manager. It’s narrower and more technical than a brand campaign.

## **Arm the Manager for the Conversation You Won’t Be In**

Winning the manager gets you into the evaluation. It doesn’t get you the business, because the manager usually has to take it to someone else, often an executive who never saw the evaluation and whose instinct, by the numbers, leans toward the incumbent.

That executive is weighing something different, whether switching is worth the disruption at all. Technical depth doesn’t answer that. What does is a performance record specific enough that the manager can hold it up against what they already know about the incumbent.

So give the manager something that holds up when you’re not there. Short enough to forward, specific enough to stand on its own.

That’s the part a manager can do that you can’t. They know what the incumbent has actually delivered, and they have the standing to say so. The data says executives default to incumbents. Experience says they still listen to the people running the line every day. That’s your way in.

## **The Takeaway**

An incumbent’s strength at the top of the organization is real. Mistaking that for strength everywhere else is the blind spot. The incumbent’s hold drops by half at the manager level, in exactly the place most challengers stop looking. Win there and you get an advocate inside the account, making your case in a room you were never going to sit in.
