An industrial spare parts distributor calculated its price the way it always had: cost plus a standard margin, the same one used across its entire catalog. The price was competitive. Even so, it lost the bid to a more expensive supplier. The factory’s buyer did not compare only the final figure in the proposal—they also considered delivery times, guaranteed stock availability, and the competitor’s track record of preventing production line shutdowns. The distributor’s cost spreadsheet addressed none of these factors.
This happens because selling to another business changes who makes pricing decisions and, more importantly, what drives those decisions. Consumers buy for themselves, using their own budget and often relying on emotional criteria. Corporate buyers purchase on behalf of an operation, are accountable to others, and must justify every dollar spent using criteria that can withstand an internal audit. This difference alone explains why a cost-plus formula that works well in retail falls short when the customer is another business.
What Changes When the Buyer Is a Business
In consumer markets, price is often the first factor buyers consider. In B2B, it comes after a list of objective criteria: technical specifications, lead time, service capacity, and a track record of reliability. Corporate buyers cannot pay based on emotion—they are accountable to whoever approved the budget, and that approval must be justified.
That is why pricing based solely on the seller’s costs is less effective in this environment. Cost is internal information for the seller; corporate buyers want to know what that price delivers in terms of results for their operations. When the seller fails to translate the price into measurable benefits, the buyer applies the simplest criterion available—comparing numbers—and any supplier that argues only on cost loses to one that demonstrates value.
Commodity or value proposition: two ways to sell to businesses
In the B2B market, there are two very different environments, each requiring a distinct pricing approach. When a product is closer to a commodity—a standardized raw material or input that any competitor can supply to the same specifications—its price tends to stay close to cost plus a slim margin, since there is no differentiating attribute to justify charging more. The lowest-cost operator wins.
When the product offers a clear value proposition—custom-built equipment, a component that solves a specific technical problem for the buyer, or a service with a higher level of support—the logic is reversed. Pricing based solely on cost leaves money on the table because it overlooks the very attribute that led the buyer to choose that supplier over the cheapest option.
Most companies that sell to other businesses do not consciously choose which of these two environments they operate in—and continue applying the same standard margin to both, treating truly differentiated offerings as commodities.
When a supply disruption costs more than the product
There is another factor that makes value-based pricing even more relevant in B2B: how important the product is to the buyer’s operations. An ordinary input may be inexpensive yet still be critical—not because it is technically sophisticated, but because running out of it can bring an entire production line to a halt. In this case, a corporate buyer will not risk supply continuity over a small price difference, because the cost of downtime far outweighs the savings on the purchase.
This reasoning allows the seller to justify the price based on delivery reliability, safety stock, and technical support—attributes that do not appear on the product cost sheet but directly influence the buyer’s decision. Ignoring their importance and competing solely on the item’s price means wasting one of the strongest arguments available in B2B sales.
Price by attribute, not by product
The practical implication is that, in B2B, pricing should be based on the attribute the buyer values, not the individual product. Two products with similar manufacturing costs may justify very different prices if one solves a problem the other does not—lower maintenance, easier integration, shorter lead times, or an extended warranty.
Listing these attributes before preparing the pricing proposal helps move beyond the default one-size-fits-all margin:
- what problem this product solves that its closest competitor does not;
- what it costs the buyer to go without this differentiator (downtime, rework, risk);
- whether a competitor offers the same level of that attribute at the same price;
- whether the margin applied reflects this difference or is the same as always.
When the answer to the last question is “it’s the same as always,” B2B pricing is probably still cost-based, even if the salesperson believes they are already selling on value.
A numerical example of how the attribute changes margin
A company that manufactures industrial filters sells a standard model that costs R$100 per unit. Treating the product as a commodity, it applies the industry-standard 40% markup:
price = cost × (1 + markup) = R$ 100 × 1.40 = R$ 140
However, one customer operates a production line where replacing the wrong filter causes unplanned downtime—and the model being sold needs to be replaced half as often as its cheaper competitor. This benefit justifies adjusting the price for this segment by increasing the markup to 80%:
price = cost × (1 + markup) = R$ 100 × 1.80 = R$ 180
The markup calculator confirms the conversion to margin as a percentage of price, which comes to approximately 44.4%:
margin = (price − cost) ÷ price = (R$ 180 − R$ 100) ÷ R$ 180 ≈ 0.4444 → 44.44%
The R$40 difference between the two versions is not an arbitrary markup. It is the price of an attribute that the corporate buyer already values and is willing to pay for, because the cost of not having it—a production line shutdown—is greater than the price difference.
Bringing the criterion into the sales proposal
Turning this approach into a standard sales practice does not require restructuring the entire sales process. It requires changing the question that opens the negotiation. Instead of leading with the price and justifying it afterward, B2B salespeople are more effective when they first ask what the buyer's operation stands to lose if the product fails, is delayed, or does not meet the expected technical standard.
In this context, markup and margin are still just ways to put the calculation into practice—the markup glossary helps avoid confusing the two percentages when preparing the proposal. What determines whether the proposal wins or loses is not the formula used to arrive at the figure, but whether that figure already addresses the objective criterion the corporate buyer will require before approving the purchase.
The lesson B2B offers for any pricing strategy, including direct-to-consumer sales, is the same: a price that does not convey what the product solves is merely a cost calculation disguised as a commercial proposal. In a corporate setting, this gap is more apparent because buyers have processes and criteria to follow and must justify their decisions—but the underlying problem is the same in any sale where the price must communicate the product’s value on its own.
