The case is as follows, the company has it's own calculation sheet which includes all the equipment needed for the project along with some additional charges like, site preparation, extra warranty & on-site training,
the company will calculate the equipment price based on the previous elements, however, when they send the quotation to the customer it should show only 1 line which will be the main item 'equipment price' (item Price+the elements+ the margin)
the reason of not using the WBS, because it will not affect the item price but only will add a new line to the quotation, and the condition here is to send the quotation with one line only include the main item
Example:
Item: ABC Sales Price = $10
custom & Clearance = $2
on-site training = $3
extra warranty = $3
the quotation line should be:
Item Name: ABC
QTY = 1
Price = 10+2+3+3 = $18 + 5% Margin = 18.9
