Companies competed tor raise funds for Children's Hospice South West in the £50 Challenge, sponsored by Exeter-based law firm Ashfords LLP.
Teams had to generate as much money as possible within a 10-week period from a start-up investment of £50.
Fundraising events ranged from silent auctions to frock swaps and even leg waxing. Overall the challenge raised more than £15,000.
Accountants and financial planners Old Mill were the winners after raising £5,772. AC Mole & Sons came second, with £2,314, and Bishop Fleming came third, banking £1,543.
Ashfords entered five teams from across its various offices, raising more than £5,000 in total. Other businesses involved included Somerset College and Optix Solutions.
Stuart Mathews, partner at Ashfords, said: "This is a fantastic achievement for a very worthy cause. Every penny raised has gone direct to Children's Hospice South West, to help and support children living with life-limiting conditions and their families across the South West."
Staff at Old Mill ran a number of events to raise cash; they started the challenge by using the £50 to buy cake ingredients and holding a bake sale. Other events included a cheese tasting evening and a sponsored waxing.
The sponsored wax, which raised over £700 towards the total, involved all the male members of staff; colleagues bid on who they wanted to get waxed by donating on a Just Giving site and the top three had their legs or chest waxed.
The biggest fundraiser was a charity auction, which raised more than £4,000. Local firms donated prizes, including Land Rover Experience Honiton, who donated a half day experience for two. The highest bid was £600 for a day yachting, which was donated by one of the Old Mill partners.
Mark Neath, head of the Exeter office and one of the waxing victims along with colleagues James Fowler and Barry Martin, said: "It was a real team effort – everyone helped think of the ideas and make them happen. There were a few we didn't do – like bring your dog to work day – we felt with new carpets, it probably wasn't a good idea."
Old Mill staff were also very generous with their own donations, with some of the men caught up in a bidding war to try and make sure they didn't get waxed.
Mark added: "I'm absolutely delighted with the amount we raised, staggered actually, it's a huge achievement. The generosity of local businesses in donating prizes for the charity auction was amazing.
"Our team were brilliant too, everyone came together to do their bit and we had so much fun with the events. I would recommend other firms to get involved, it has been great for team spirit."
