How to calculate the difference of 5% among online export verification documents, batch approval and verification documents?

-For example, if the amount of foreign exchange received is 1000 and the amount of the write-off document is 990, the write-off difference of this transaction is 200 (foreign exchange overcharged).

Whether it exceeds the write-off variance range (1000-990)/990= 1% (not exceeding) is not allowed.

Is the difference positive or negative? Which is good for the enterprise?

-It is of course best for enterprises to check more verification documents with less foreign exchange, provided that they can be within the verification difference. (Because some handling fees will be deducted when foreign exchange comes in) But the difference between each write-off should be recorded, so as to make sure that it is not too bad.

Is the foreign exchange verification quota better than the customs declaration quota?

-No, as mentioned above.

It can be less or more, depending on age.

The amount of foreign exchange written off is generally less than the amount declared.
