BrandForge

Founder of BrandForge here.

Early on, proposals on BrandForge could go back and forth indefinitely. A client counters, the specialist counters back, repeat. In practice this just meant deals dragged for days over small amounts, and the people most likely to walk away weren't the ones being unreasonable, they were the ones who got tired of negotiating first.

We capped it: one counter from the client, one counter back from the specialist, then it's a straight accept or reject.
