Company size is one dimension of power. In the Academy of Business Negotiations Power and Leverage module, the next input is portion of business: what share of their revenue you represent, and what share of yours they represent.
Those two percentages change how hard you can press and whether a deal is worth the risk to the rest of the book.
Two numbers, not one
If a buyer is half of a vendor’s revenue, the vendor’s options shrink. The buyer does not have to make a speech about it. Dependency does the work. Flip it: if that vendor is a small slice of the buyer’s category, the buyer can push terms a diversified vendor would reject.
A healthier vendor book keeps any one customer from being able to break the year. Some companies even slow a dominant channel on purpose. Near-term revenue can drop. Negotiating position often improves.
Read it from both sides
If you are the concentrated side, stop pretending you have the same leverage as a diversified peer. Prepare trades that protect profit dollars without forcing a fight you cannot finish. If you are the concentrated buyer, use the position with care. Burning a dependent vendor can look like a win this quarter and a supply problem next quarter.
Before a renewal, write both percentages down. Then set the ask, the tone, and the threshold for whether the deal is worth it.
Let the number change the plan
Portion of business is a strategy input, not trivia. A vendor at 8 percent of spend can test a firmer ask than a vendor at 40 percent. A buyer at 12 percent of a vendor’s revenue should not expect the same concessions as a buyer at 50 percent. If you do not know the number, you are guessing at leverage.
Pull your figure from the P&L first. Estimate theirs from filings, channel mix, and what they have already said. Update it when volume shifts. Concentration moves faster than company size.
Practical takeaway: Before you press, know what share of their business you are, and what share of yours they are.
