Your Local Accounting and Tax Specialist

Heather Bennewies opened Plan B Accounting and Tax in March 2013 to fill a void in the Mitchell area for preparing personal income tax returns for individuals and owners of small businesses.

Heather graduated from Nipissing University with Bachelor of Commerce degree after obtaining a certificate in Business Administration Accounting from Fanshawe College and in November 2017 I achieved the professional designation – CPA,CGA.

Plan B Accounting offers bookkeeping services using QuickBooks and Sage (Simply Accounting) software. In recent years, with cloud services becoming more popular QuickBooks Online (QBO) was added as an option. Excel is also used to service any smaller businesses that may not need the features of a full accounting software.

As part of the bookkeeping function, Plan B Accounting is also able to service their small business clients with payroll services, including T-4 preparation, and calculating and filing GST/HST returns.
