Feature request: Etsy style fee billing for Marketpress

Feature request:

Track new listings and completed sales for each shop and bill the shop owners for their fees monthly with a click to pay checkout to pay their bill.

Let's be clear on what this is NOT.
This is not about chained payments...

This is the actual Etsy style business model for shop fees.

This is not done at time of payment.

Etsy bills shop owners monthly for listing and sales fees.

Can we create an addon to marketpress that does the same.

Track new listings and completed sales for each shop and bill the shop owners for their fees.
