Trade-off and concession both describe giving something up, but only one of them requires someone else to be asking for it.
Use "trade-off" when something is exchanged within your own decision for a gain on another dimension, with no second party required. Use "concession" when something is given up specifically to satisfy another party in a negotiation.
Self-contained exchange versus surrender to another party
A trade-off can be entirely self-contained: you accept less of one attribute to gain more of another, inside your own decision, with nobody else needing to agree to anything. A concession is different in kind — it's something surrendered specifically because another party asked for it or needs it satisfied. Calling a self-imposed trade-off a "concession" implies a counterpart who does not exist, and can misrepresent who actually forced the decision.
"We traded off a slightly higher unit cost for a more reliable supplier — our own call, nobody asked us to" is an internal, self-imposed trade-off. "As a concession to the client, we agreed to waive the setup fee in exchange for a two-year contract" is something given up specifically to satisfy another party.
The mislabeling risk runs in a specific direction worth watching for. Describing an internal budget reallocation as "a concession we made" implies someone outside the team pressured the change; "a trade-off we made" more accurately describes a decision the team made on its own, with no outside pressure at all.

If naming the decision requires naming who you gave something up to, it's a concession. If the exchange is entirely inside your own decision, it's a trade-off. That question is usually enough to settle which word the sentence actually needs.
Practice scenarios
Practice choosing between trade-off and concession in situations like:
- describing an internal decision nobody outside the team pressured
- summarizing something given up specifically to close a negotiation
- correcting a sentence that implies outside pressure where there was none
Useful practice phrases:
- "We traded off [X] for [Y] — our own call, nobody asked us to."
- "As a concession to [party], we agreed to [what was given up]."
- "That wasn't a concession — nobody outside the team asked for it."
A trade-off answers to no one but the decision itself.
A concession always has someone else's name attached to it.
