Hello,
I can migrate your 2 websites to shopify and also integrate it with ebay and amazon.
I have previously :
1 ) Migrated products, orders, images, customer (Data) from 125 custom stores to eight shopify stores.
2) Simple custom Shopify app interface to migrate store data to Shopify store.
3) Automated syncing of customer store data with Shopify system. So there is a new product added in custom server, then Shopify app will automatically migrate it to Shopify system.
4) Migrated stores,products,product images,customers and orders information of last 4 years using private shopify APP. Also managed same product sort order in shopify in migration procedure.
Hoping forward for a positive reply and look forward to work with you on this one,
Regards,
Ati
