Until recently I haven pretty much taken care of all my own accounting as things have been quite simple. But as business has picked up considerably, and im currently in the process of buying 2 more businesses (1 restaurant and 1 small food dist company) things are going to get a whole lot complicated.

So how much should an accountant cost me? I would need services such as:

VAT returns
End of year limited company account submission
Corporation tax
Payroll

Im assuming that the fees are going to be related to turnover??
