Colkirk was actively engaged in trade at Yarmouth from 1388 until the year of his bailiffship. Early on he formed a profitable and long-lasting partnership with another burgess named John Spitling, with whom he is frequently recorded as shipping herring, cloth and grain, unloading many cargoes of salt, and importing wine from Gascony.
