Thank you for your answer. I am looking to find a tax accountant that has knowledge of ecommerce law and who can provide solid advice on how to manage an internet business from sole trader stage to limited company. I am lost for where I can find one, could you point me in the right direction or recommend a firm or person that is small business friendly?
Well frankly Trevor it's not exactly rocket science! Your sole trader activity simply stops and the subsequent transactions pass through the company's books of account. What I would do is to make a written note of your internet sales and expenses and aggregate them monthly, posting it to the appropriate ledger headings. You don't even need an accounting package, a simple spread sheet will suffice; it certainly does for two companies I operate.
As for recommending an accountant to do this for you Just Answer protocol precludes me from making any such recommendations. However, it is well within the capabilities of any high street practitioner. Ask your friends or business contacts if they know a competent book keeper that they could recommend.
I do hope I have helped point you in the right direction. Please be so kind as to rate me before you leave the Just Answer site.
