This is how I see your logo. I went for this style to not fall in the trap of making it too playful. Accounting and book keeping should say serious, trustworthy and dependable. Giving it a classy finish, the logo is dynamic (showing off quick and easy) and at the same time elegant. The red rusty background is to give you an idea of how your bussines cards could look. If you think this is something that might work for your company's strategy, I will improve it to your liking. Thank you!
