We don't do MACs. We support QuickBooks desktop on PCs - any version for the last three years. We also support QuickBooks Online.
We can help you set up your payroll in QuickBooks so you can do it yourself. But we have another alternative that may work better for you. We use a separate payroll service and do all the work for you in our office. Then we help you post the results in your QuickBooks software.

Too much hinges on the impression your paperwork makes. Don't take a chance. Have us do a review before you submit a report for any financial purpose - including your tax return.
