When the things to be confirmed are confirmed, we will make a formal quotation. If there is a mode of transportation, how much freight will it cost? If the product drawings on the quotation sheet are not clear, attach clear ones separately, and use ps to compress the size but not the resolution.
It is best to follow up the quotation in time after it is issued. Make a phone call. Making a phone call may be more useful than sending ten emails. Customers hear your voice, you register, customers will remember you more easily, and emails may never remember you.
