A payment item is a one-sided turnover on a current account, representing either a credit or a debit.
Hi, in the sentence above, what is the exact meaning of turnover?
The sentence is in the bank operation context.
Turnover: is the gross income that a business receives.
So, all the Sales Receipts that a business has: ie its total income, is the turnover.
I think it would help if you gave us a little bit more information. Perhaps more of the paragraph in which the sentence appears. Sometimes the best way to find the meaning of jargon, or of a technical expression, is to actually ask someone in that line of work.
It could be, that it is not proper English, but a misuse of English, that has become an accepted practice.
Possibly in a Chinese Bank, they know exactly what they mean by a 'one-sided turnover'.
