Hello
We are ready to work on this project and to start immediately
We have the requirements to handle this project effectively and timely too.
For this job we will be using our vast experience on ebay/Amazon listing (bulk) to handle it,
Regarding your work, we will be working mainly with excel formula and macros
My excel file which we will update with files download every 2 to 4 hours (Mon-Fri except on Sunday (once or 2 times) ) from your Amazon and ebay stores.
And synchronize to produce update files for the Amazon or ebay as the case may be.
If we have all the inventory that you are listing or will be listing.
We will have all the Asin ready, so when it is live in ebay and not in amazon, our excel will produce a file that when uploaded will list this file on amazon.
Regarding ASIN change, except we can attach extension to this SKU, sometimes, it is not that easy changing ASIN on the same SKU.
But w can still achieve this by deleting the product to list after 2 to 3 days.
I will like state here that I can give you same experience, working with excel.
As I do not yet have a vast knowledge in the API.
Looking forwarding to working with you
