Hi there TPBait,
Thanks for reaching out about your currency conversion. QuickBooks Desktop is a great tool able to assist you in keeping track of sales and expenses so you know the amount of profit for your company. I can point you in the right direction for assistance with this calculation.
For assistance with this calculation for currency value being off, I recommend reaching out to the QuickBooks Desktop support team outside of the Community. They'll be able to view the error with you in the program to best assist at getting it resolved so the value in home currency is accurate. You can reach them using the methods outlined in the Intuit Canada QuickBooks Desktop software support policies.
If you have any other questions, feel free to reach out here.
