The BSA has been targeting London companies throughout the year and is gearing up for a festive campaign designed to highlight even more offenders.
Among the latest settlements Network Disaster Recovery Ltd, paid £15,000 for under-licensing Microsoft and Symantec, Osel Architecture Ltd had to fork out £8,000 for using Autodesk and Adobe software without licenses and Home Inspector Training Ltd settled for just shy of £5,000 for using Microsoft.
The companies also shelled out to buy the legal software to get them back on the right side of the law.
"We will be looking closely at businesses in London ahead of the Christmas period and will be increasing our enforcement activity" said Alyna Cope, spokesperson for BSA's UK Country Committee.
"There are still too many businesses in the capital that are negligent when it comes to managing their software and we are calling on all software users to blow the whistle on illegal software use," she added.
The BSA ran a two-month campaign in London this summer aimed at targeting the capital and managed to reach settlements with a few unlicensed software users including Soho House.
