Hi,
As per your description, I would like to know the following before going ahead.
1. The API form Shopify and amazon has to be purchased because we need API keys to get them integrated to your existing.
2. Since you already have an existing system, thus I would like to study it before going further. Kindly provide demo access and documents.
We are 100% confident because we have prior experience in Big ERP, CRM development with the help of Salesforce integration. This, these APIs can also be integrated to the platform
Looking forward to have a conversation where we may mutually go for an official proposal.
Regards,
Mit-
