I met Ed from Sleek when he was visiting our coworking space in London. After a quick chat, Ed explained how I could move my accounts online and also discussed R&D tax credits. His advice has been invaluable!

I truly wouldn’t be able to run my business without Sleek. Whilst I’m great at marketing and the sales side of running a business, I’m just not a numbers guy! Sleek has changed the way I look at an accountant.
