integration of saas system into shopify

I do have a saas system for ecommerce and online services. Our system is live. I do wish to add our system to Shopify app market as part of our list of integration tasks. I am looking for a seller that already integrated apps into Shopify platform. Please ping me with urls of apps that you integrated them into Shopify. Without that I will not move f.w with anyone. If you send me a message without sending me the urls its mean that you didn’t read my requirements and it will be hard to move f.w with you.
