A negotiated commission rate that applies to this consignor specifically, used instead of whatever the sale's standard fee schedule charges. Leave it blank to use the normal rate; set it only when this seller has a special deal. The rate is entered in basis points (bps) — 100 bps equals 1%, so a 4% commission is 400 bps.
This only overrides the commission portion. Yard, insurance, checkoff, and other per-head fees still come from the sale's fee schedule. A per-consignment override, if set, beats even this seller default.
