Accountancy Problems

Hello Amazonians

Can anybody recommend an Accountant specialising in online retail/ Amazon and other marketplaces who is situated in the North West? Also, how easy is it to change accountant?

My accountant has just made an error on my VAT return, six months after making a massive error on my end of year accounts that literally could have bankrupted me. They quite clearly do not understand reverse charges, European VAT rules and FBA.

Any recommendations would be greatly appreciated.

Many thanks
