Supply Chain Management with Zoho

I have a growing product based home business with approx. 500 skus. I mostly sell wholesale to stores. I use Shopify for prepaid online orders and QBO for accounting and terms customers. I want to implement Zoho Inventory as my central inventory mgmt and need someone with direct experience integrating Zoho Inventory + Shopify + QBO. * initial Zoho set up * connecting Shopify and QBO correclty * making sure inventory is not duplicated or deducted twice * setting up the workflow for terms/customer invoices * basic training so I understand how to use the system day to day Please respond only if you have personally implemented this combination before. I prefer a fixed-price project we can negotiate.
