Reporting SaaS - automatic Shopify performance reports by email

Built a Shopify app that connects to a store and automatically sends a performance report by email - revenue, orders, week-over-week comparison, top products, and a daily revenue sparkline. Also added an estimated margin calculator (based on a COGS percentage you set) since raw revenue alone doesn't tell the full profitability story.

Would love feedback from anyone running a Shopify store, or thoughts on what would make it more useful.
