Tradeteam has signed a five-year distribution deal with C&C Group to service its Scottish customers.
This comes six months after the two companies agreed on distribution in Northern Ireland.
The agreement will see Tradeteam deliver C&C's brands, including Tennents lager to pubs, clubs and bars, and packaged kegs, bottles and cases to wholesalers.
C&C will benefit from "strategic stock replenishment, forecasting services and an overspill storage facility" for the brewery at Tradeteam's neighbouring Cambuslang site.
The logistics firm has handled C&C's distribution since the company bought Wellpark Brewery and the Tennent's brands in August 2009.
Tradeteam account director Simon Gallimore said: "We will certainly be drawing on our extensive experience of the Scottish marketplace and applying the same innovative delivery approach used to meet C&C's requirements in Northern Ireland."
Andrea Pozzi, C&C group head of supply chain services, said: "Tradeteam has proven itself as a reliable logistics partner and is in a great position to help us continue to promote and increase the presence of our flagship brands in Scotland."
