Gross margin can look healthy while the deal still fails. In the Academy of Business Negotiations P&L module, the Operational Expenses lesson sits under COGS: overhead that does not vanish when volume drops. Ignore OpEx and you can accept terms that look strong on a spreadsheet and still leave fewer profit dollars.
What lives in OpEx
Operational expenses are the costs you incur to run the business that are not tied to a single sale. Staff salaries and benefits. Office or warehouse lease. Legal and accounting. Software. Insurance. Marketing that is not attached to one SKU. If you sold nothing today, this layer would still be there. That is why it is easy to forget at the table. Price and unit cost dominate the conversation. Overhead does not shout. It just sits there and taxes every extra requirement you agree to.
Requirements have a cost
In B2B deals, OpEx is often in the background rather than a direct lever. It still decides whether the relationship is worth it. A large buyer can add complex compliance, unique packaging, dedicated reporting, or intensive promotional management. Each of those items needs people, systems, and time. A deal that looks solid on gross margin can erode quickly once you staff those extras. The same math applies in reverse. Every requirement you impose on a seller has an OpEx cost on their side, and that cost shows up in what they will give you elsewhere.
Price the deal all-in
When you evaluate terms, run the all-in picture, not only the unit economics. Ask what headcount, process, and complexity this account actually requires. Gross margin targets also vary by industry because fixed costs differ. A thin margin that works for a high-volume retailer can fail in a business with heavy research, compliance, or service load. You do not need to be a CFO. You do need to know whether this deal covers overhead and still moves net profit dollars in the right direction.
The practical takeaway: Do not stop at gross margin. Price the deal on all-in profitability, including the OpEx it will create.
