In my opinion, turnover = sales revenue. It's the top line on the income statement. If the company has other revenue that is not derived from its principal activities, it should be put on the "other operating income" caption.
It's PRC GAAP. Do you ask under other GAAP? say, IFRS, HBII or US GAAP.
Hi, thanks, Lixin. In some other situations, these two terms are probably different. This is a item in an application form, asking the applicant to fill the amount of turnover/sales of the current employer.
