Startup Idea: Advanced Etsy Sales Tracker Software

Startup idea to develop an advanced Etsy sales tracker. This program should provide complete details about sales, customer information, messaging history, payment and shipping tracking. It should have the ability to print reports, and most significantly, enable users to keep track of the production cost and time for each item to determine profit efficiently.

I frequently sell handmade items on Etsy. Yes, they have an app and you can track sales on their website, but it seems incomplete or lacking.

I would pay for a more advanced program to keep track of my Etsy sales.

I would like a more detailed and easier way to look at my sales where I can see everything more easily and keep track of my customers.

Such a program would list date of sale, customer name and address, link to customer's Etsy, messages between us, and have boxes where I could check when I received their money and when and how I shipped their item (and even include shipping labels and allow me to scan in shipping receipts), it would also allow printing reports, etc.

Most importantly it would allow me to keep track of my cost for making each item including keeping track of the time spent making the item. That way I would know exactly what was spent producing each item and what it sold for.
