Link to supplier webpage for Canadian clients

Hello. We are brand new to all of this so this may be a very simple question to answer which I am hoping it is. We will be holding and shipping product in Canada for an American company. The product is manufactured in Canada so this will save the supplier some headaches on their end. We are curious if there is link that can be set up on their webpage to allow Canadian customers the option of ordering from us. We aren’t rushing into starting our Shopify store at this time, we are more looking into warehousing and shipping at the moment. We are also looking how the customer gets billed for the shipping cost. I can’t seem to find any option other than us paying for the shipping and then billing the supplier which seems like a headache. I do have more questions, but one thing at a time. Appreciate any and all help with this.

Yes. By all means I am open to suggestions. Please feel free to share here.
