Your accountancy practice may specialise in dealing with the accounts of charities, solicitors, financial services firms, insurance brokers, etc. whose rules of accounting are different from the ones covered by the Companies Act. In this case, if you consider outsourcing of accountancy work of your firm, then you need to find out whether the provider you may team up with is experienced enough to carry out the special accounts production work that you desire. For this situation, on the off chance that you consider outsourcing of bookkeeping work of your firm, at that point you have to see if the supplier you may collaborate with is sufficiently experienced to complete your accounting work efficiently. Failing to do so will cost you a lot of last minute surprises!
