If I integrate Toast in QuickBooks Online, can I see the toast fee and net deposits separately. Our idea is to track the toast fees as deductions from gross revenue.

I see how essential it is for you to track the toast fees as deductions from gross revenue after integrating it into QuickBooks Online (QBO), @Vabburi.

I recommend contacting Toast app customer service since they have the essential tools and expertise to assess your account particularly to generate daily sales journal entries.
