HOW TO ADD EXTRA FEE FOR SUPPLIERS

[xmax316]

I am trying to built an ecommerce website using Prestashop (last version)...

So far everthing goes ok

but now, i as a middleman, would like to add 4 extra fees:

First:

Since i will be representing several stores (let say like 10 diferent stores), each store has 100s of products. If a customer buys me 3 products from 1 store, 5 from another store and so on... I need to charge the customer a pickup fee from each store in order to collect all the products he order so i can sent them by UPS or DHL...

So... my question is... How do i setup a collecting fee for every order.

Pls notice that if a customer only buys 5 products from 1 supplier i will charge him only once. for example...

If i stablish that i charge $20.00 for collecting from each supplier, and customer buys item from 5 diferent suppliers that will be $100.00 as collecting fee.

but is he buys 5 items from 1 supplier it will only be $20.00

 

Second:

If a customer buys me 3 products from 1 store, 5 from another store and so on... I need to charge the customer a product invoice fee from each store (supplier). This product invoice is requested in my country by DHL or UPS, since i will be selling worldwide, and it is done by the supplier of the product.

This invoice or ducment has a cost of $25.00...

So... my question is... How do i setup an Invoice of Product fee for every order????

Pls notice that if a customer only buys 5 products from 1 supplier i will charge him only once. for example...

The real cost of that document is $25.00 and customer buys 10 items from 5 diferent suppliers that will be $125.00 .but if he buys 10 items from 1 supplier it will only be $25.00

 

Third:

Since i am not in USA, here in my country it is quite dificult to get an API key for DHL or UPS. So that means that i have to type in all the shipping rates manually.

Now, becuase of that i need to add also a INSURRANCE FEE that its normally 1% from the total price of Products (services not included) How can i add that 1% into the INVOICE???

 

Fourth:

Accourding to DHL and FEDEX, i can ship what ever i want. But when its about dangerous cargo, i need a document that has fully description of it.

for example parfume... or alcohol, things like that. They will give a list of things that needs that document. Since i wont be using the online system for UPS or DHL, i need to know how can i add a charge for it. Pls notice that the document has a cost of $100.00 from each supplier. So this entry is tide with the product and the supplier.

 

Pls let me know if you have some kind of idea that can help me fix this.
