I need to be able to invoice my customers once they determine the products, quantity, etc they want to purchase from me. Due to extremely complicated shipping costs (heavy and oversized products), I do not want my customers to be taken to any of e-junkie's payment options (Paypal, google checkout, etc).
I will first need to determine the correct shipping for all items and then I will invoice them for those products. Is this something that e-junkie can do?
Please advise. Thank you.
