Startup Idea: E-commerce Accounting Software Idea

Startup idea to develop an inexpensive, reliable and efficient accounting software specifically for e-commerce businesses operating on platforms like eBay, Amazon and Etsy. The software should include features like price tracking and automatic updating.

I currently own a business that operate son eBay, Amazon and Etsy. I would seriously love to get a hold of accounting software that is faster and more cost effective than your traditional Quicken or quickbooks.

I need something that will be reliable, never have server issues and won't charge a huge monthly fee.

Some sort of price tracker and auto updater would be amazing as well. If you have any ideas for these, please email me. I would be glad to try some out (view contact info).
