The loyalty tax: how buying from the same distributor quietly costs more

Most reorders don't involve a decision. The part ran low, the distributor is already in the system, the rep is the one you call, and the purchase goes through the same channel it always has. That's not laziness — it's how a busy team keeps the line running. But it quietly relies on an assumption that usually goes untested: that the supplier you're loyal to is still giving you a competitive price.

Often, early on, they were. The problem is that the price doesn't stand still and the checking does. Once a buyer settles into a default, the comparisons stop — and a supplier's price is free to drift upward without anyone pushing back.

How loyalty turns into a tax

The mechanism is mundane, which is what makes it so easy to miss:

• The price drifts. List resets, freight and material surcharges, and ended promotions all nudge your effective price up over time. Each move is small; none triggers an alarm.
• The checking stops. Because you trust the relationship, you don't re-benchmark. There's no moment where the price "looks wrong," because you're not comparing it to anything.
• The gap compounds. Repeat across dozens of reorder lines and several quarters, and a collection of tiny, invisible increases becomes a meaningful line on the budget.

And because B2B pricing is shaped by account terms and quotes rather than one public sticker (more on that opacity here), there's no obvious signal when your loyalty has carried you past the going rate.

You assume loyalty earns you a better price. Unchecked, it mostly earns the supplier a buyer who has stopped looking.

Yes, you can end up paying above market

The uncomfortable part: it's entirely possible to pay more than another buyer — or more than the public list elsewhere — for the identical part, simply because you never compared. There's rarely a single line item that looks wrong. The surcharge is "just the surcharge," the list update is "just the new price," and your trust in the rep papers over the rest. The overpayment isn't dramatic; it's ambient.

This is the same effect consumers know from insurance and broadband, where the longest-tenured customers often pay the most. Industrial buying has its own version — and because the prices are private, it's even harder to see.

What the procurement data says

This isn't just a vibe; the research community has measured the broader phenomenon of buying that skips comparison. The Hackett Group has reported that organizations can lose on the order of 16% of their negotiated savings to off-contract, "maverick" purchasing — buying that bypasses the comparison and the agreed terms. Other analyses put the lost-savings range wider still, and Boston Consulting Group's work on "tail spend" finds that the long tail of lightly managed, fragmented purchases can account for a substantial share of total spend leakage. Separately, industry estimates suggest a strikingly large portion of organizational spend — by some accounts a third or more — happens outside negotiated agreements entirely.

The labels differ (maverick spend, tail spend, off-contract spend), but the root is the same as the loyalty tax: purchasing on habit, without a market check.

Loyalty with leverage

The fix is not to fire the distributor you trust. A good supplier relationship is genuinely valuable — for availability, service, problem-solving, and terms. The goal is to keep the relationship and remove the blind spot:

• Benchmark periodically. For your most-reordered lines, check the effective price against the visible market on a regular cadence, not just when something feels off.
• Track the history. A recorded price curve makes drift visible — and turns "I feel like this got expensive" into a number you can act on.
• Let your rep know you're watching. Quietly keeping a market benchmark tends to keep pricing honest without any confrontation. It also gives you something concrete for your next review — see negotiating with price history.

If your reaction is "but we have a contract, so this doesn't apply to us," that deserves its own answer — and it's not as airtight as it sounds. We unpack it in contract price vs list price.

Frequently asked questions

What is a loyalty tax in procurement?

A loyalty tax is the extra cost a buyer absorbs by purchasing out of habit from a default supplier without periodically checking the market. Because the buyer stops comparing, the supplier's price can drift upward — through list resets, surcharges, and ended promotions — and the gap goes unnoticed and uncorrected.

Can I really pay more than list price without realizing it?

It's possible. In B2B, the price you pay is shaped by account terms, quotes, and add-ons like freight and surcharges rather than a single public sticker. If you never benchmark against other sources, your effective price can end up at or above what others — or even the public list elsewhere — would charge, without any single moment where it looks wrong.

How much does off-contract or habit-based buying cost organizations?

Industry research puts real numbers on it. The Hackett Group has reported organizations can lose on the order of 16% of negotiated savings to off-contract, maverick buying, and analyses by firms like Boston Consulting Group find that unmanaged tail spend can represent a meaningful share of total spend leakage. The common thread is purchasing that bypasses comparison.

Does avoiding the loyalty tax mean dropping my preferred distributor?

No. The relationship can be worth keeping for service, availability, and terms. The fix isn't disloyalty — it's adding a market check, so you keep the supplier you like while making sure their price stays in line with the rest of the market.
