Outsourcing back-end functions such as accountancy is a good way for any SME to comply with the law and cut costs.
A third-party accountancy company can take care of the number crunching and compliance while you get on with the important work of managing your business and turning a profit.
The main accountancy services these companies offer include:
- Bookkeeping and Financial Records.
- Tax Compliance and Returns.
- Payroll and Pensions.
- Annual Accounts and Financial Reporting.
- Business Advisory and Financial Planning.
The good news is that there are almost 2,000 accountancy firms currently plying their trade in London.
The bad news is that finding the one that is the best fit for your business can be a bit of a headache.
