We resell instrumentation from different suppliers to our customers and have to import the items to Trinidad. Therefore I would get a list price in USD (I may have a discount factor to apply depending on the supplier), I have to the add various charges including S&H, Freight, Insurance, Transportation, Duties, etc and then add a markup to resell. Reselling is done in TTD or USD depending on the customer. I would therefore like to add these cost separately and also to view my estimated profit margin for the quotation. Note that one quote may include several suppliers. How can ZOHO assist in achieving that?
