Hi,
A system account is really only a link to an account used for a specific purpose. Also, there's no "Turnover system account" :-)
What you'll need to know is exactly which accounts contain turnover - and then GetEntryTotalsByDate() for these.
If you KNOW that ALL sales are done using customer invoices - i.e., no manual customer invoices, and no finance vouchers - you can conceivable also retrieve the turnover via invoices instead. However, that would be sort of error-prone, since some turnover booking may be done manually.
BR,
