Atreus Accountants Ltd. is an accountancy firm that helps and supports small and medium-sized businesses and aspiring business owners in the financial running of their ventures. Situated in Wimborne, Dorset we offer our clients a wide range of general accounting services from tax returns, bookkeeping to corporate accounts and payroll, as well as offering sound business and financial advice to both individuals and companies.
Many clients have told us they saw accountants as 'dull and boring' and would speak to them in 'confusing and complicated ways, seeming like another language'. Our mission is to change this perception, effectively and efficiently managing our clients' accounting and financial needs, saving them time, money and stress, but also forming strong, personal working relationships with them at the heart of what we do. Ensuring we bring a relaxed atmosphere and 'jargon' free communication in our approach, sharing our knowledge and passion to see their businesses flourish.

Bookkeeping and Annual Accounts

Spending too much time updating your sales and purchase ledgers? inputting payments?

‚ÄčAtreus Accountants bookkeeping services can do this for you, simply leave us your invoices, receipts, statements, etc. monthly and the tedious work is taken care of using out cloud based software.

We find that most of our clients spend valuable time on keeping their finances up to date, precious time that they could be using to make further sales, gaining more business, or time they could be using to enjoy the finer things in life.


Atreus Accountants Ltd. can take this stress and time away from you, leaving you to focus on the things that matter, running your business, making sales and spending time out of work doing the things you enjoy doing.

Our accounts professionals carefully piece together and analyse your personal tax return ensuring all aspects are correct and follow the HMRC guidelines, whilst also ensuring you aren't paying more tax than you should be.

Payroll/ CIS

Weekly, monthly, annual payroll and CIS can be a strenuous time for an employer, especially since the introduction of Real-Time Information (RTI) . Working out the Tax and National Insurance owed to the HMRC, final wages of the employees, printing of wage slips, submissions to the HMRC, etc. Time spent on undertaking these jobs soon mounts up, and so does the money being lost by not making sales.
