Nibbling

What it is

Asking for small additional concessions after the main deal is already agreed, exploiting the other party's desire to close and avoid reopening negotiations.

How it works

Once both parties have invested significant time and emotional energy reaching agreement, the commitment to close is strong. The nibbler exploits this by requesting small add-ons that feel trivial relative to the overall deal. Each nibble is small enough that refusing feels petty, but cumulatively they represent significant value transfer.

Real-world examples

  • •"Oh, one more thing — could you throw in free shipping?" after a complex deal is negotiated.
  • •Adding scope to a consulting engagement after the contract price is agreed.
  • •"Since we're already doing X, it wouldn't be much to also do Y, right?"

Ethical guidelines

  • ●Minor nibbles are standard practice; major nibbles disguised as minor ones are bad faith.
  • ●If a concession is worth asking for, it was worth including in the original negotiation.
  • ●Repeated nibbling erodes trust and relationships.

How to defend against it

  • ►When someone nibbles, respond with a reciprocal request: "I can do that if you can do this."
  • ►Say "Let's reopen the full negotiation" — this usually stops nibbling because the nibbler doesn't want to risk the main deal.
  • ►Set clear boundaries at the handshake: "This is the complete agreement — any changes require renegotiation."
