AMAZONFBA
Hello,
I see your client have US account and want to sell in UK. Never try to create another account for sake. Amazon Policy is one house one account this means if you try to create another account on same details even IP address then amazon will suspend both of them.
1. If the client has an Amazon seller account in America do we need to set up an Amazon FBA account under a different email address?
Amazon have option in the seller central of Sell Globally and will charge you for that, if you Sign up for UK seller central through your US account you will additionaly get 6 countries option to sell including Italy, France, Germany, Netherland, Spain and UK.
After brexit you need seperate VAT to sell in each of them as then UK VAT will not work.
2. How quickly can we get the following tasks above completed by?
Mostly one to two week but if they put any objection in it like you told "The country of origin you selected during registration does not match the information in the documents you provided" then it may take longer. Then you have to get them the evidence.
3. What will you need to complete the project and what will be the process?
I need your SC account through User Access but better you do it on your own to learn the process and I will guide you how to do it. It is simple they will just ask you some basic question, but as you already registered in US you don't have to get with many verifications.
Just message me so we can discuss it.
