  • Every transaction is accounted for
  • Your books are closed at the end of each month

Your new partner in virtual accounting

Make Thornhill Accounting Services your newest team member to support you wherever you are—whether in the office or working from home. The combination of our managed services and proprietary platform give you the simplified accounting solutions you’ve been wanting to see.


TAS is the best accounting partner that you can choose for your business to get accurate and timely accounting and reporting for the long-term, further enabling you to achieve your financial goals.


The TAS platform incorporates the latest encryption technology and two-factor authentication to ensure that your sensitive information is secure. Additionally, company management has complete control of who has access to the platform and what information is available to them.


Accounting doesn’t have to be complex. Our platform makes “updating the books” another item on the to-do list, alongside getting the mail, processing emails and answering calls.

Managed services + proprietary platform = accounting success

It’s not accounting software. It’s not hiring a CPA. It’s a combination of management and an easy-to-use dashboard that makes updating the books simple for you.


We provide an easy-to-use dashboard as part of our proprietary platform to help bridge the gap between data entry and comprehensive accounting services. No need to learn more complex accounting applications.


Our managed services provide you with your own personal bookkeeper/accountant who is readily available when you have questions or need help.


Premium services available at a discount including business and individual tax preparation and the complete offering of Thornhill business and tax advisory services.

Quick & easy setup

Our simplified, virtual platform and implementation process will have you up and running in just a few weeks. Unlike some other outsourced accounting solutions, there’s nothing complicated about it. It’s all-inclusive, there are no hidden costs.
