Company size is one power input. In the Academy of Business Negotiations Power and Leverage module, the Portion of Business lesson adds a second number that can outweigh the org chart: what percentage of their revenue you represent, and what percentage of your revenue they represent. Those two figures change how hard you can press, and how painful a sour relationship is.
Read both percentages
If Amazon represents 50 percent or more of your business as a vendor, your negotiating position is different from a vendor with no single buyer above 15 percent. If one customer is half of your book, they know it. When they push on terms, saying the deal is not worth it carries a high cost. Your alternatives shrink because replacing that volume is slow and expensive. On the buyer side, a vendor who depends on you while they represent a small slice of your sales gives you structural leverage without a speech. You do not have to threaten. The dependency does the work.
Diversification is a negotiating position
From a vendor view, a diversified book is healthier. When no single customer sits above 20 to 25 percent of revenue, you can invest more heavily in other accounts if the relationship sours. That changes the tone of every conversation with that customer. Some companies even scale back sales with a giant retailer on purpose. Short term, you may leave revenue on the table. Longer term, you keep a real alternative, which is what makes a firm position credible.
Let concentration set the strategy
Know your concentration. Know theirs. If you are a large share of their volume and they are a small share of yours, your pressure threshold is different than the reverse. Feed that math into tone, asks, and what you will accept. If they are half of your revenue and you are a rounding error in theirs, a hard press with no replacement plan is not a strategy. The other side can feel that dependency even when nobody says it out loud. If the package does not improve profit dollars after concentration risk is counted, the deal is not worth it.
The practical takeaway: Before you negotiate terms, calculate both concentration numbers and let those percentages set how hard you press.
