Swedish to English Bus/Financial Business/Commerce (general) sales

"sidomarknad" as opposed to "huvudmarknad".

"Huvudmarknad" is the main market, i.e. the group of customers to whom I am deliberately targetting my services. For instance, as a translator who works freelance, my main market would be translation agencies/companies who buy my work.

However, there is conceivably a "sidomarknad". In the course of my work I produce glossaries, TM and other such things which could eventually be sold to someone else whom I have not been targetting directly who just might be interested in buying some of my services or the some spin-off service or product that I produce. That is what is meant here by "sidomarknad".

A few Google searches have come up with "Curb Market", does that sound right? I have a feeling that is not quite on.
