Have you been involved in eCommerce software or marketplaces / platforms? Looking at an opportunity (think Etsy or Shopify for a specific product type) and would appreciate speaking with other folks with experience there

Few key questions right now:

1. Valuation - how did you approach valuing the business when a significant portion of revenue comes from transaction fees?

2. Diligence - what did/would you focus on in diligence? Any unusual metrics you would look for?

3. Credit card processing - one potential growth lever is offering credit card processing (right now, each merchant uses their own processor account) and sharing the volume discount. Obviously, this introduces more complexity with remitting the payments to merchants. If you have dealt with this, what surprises did you encounter?
