The big question that is always a challenge for a marketplace is refereeing between buyers and sellers when there is a conflict. Basically, what processes are in place to make sure there is a resolution if a transaction turns sour between buyer and seller. Ebay, for example, tends to favor the buyer and any loss for the seller is to be viewed as a "cost of doing business." Conversely, Amazon does a bit more with eating some costs themselves if there is an issue. These are gross generalizations about these marketplaces, but in order for a marketplace to succeed it needs to be trusted and liked by BOTH buyers and sellers. Otherwise, each group will continue to look for alternate channels outside your marketplace. Let me know if you would like more insight, specifics or solutions.

I think the most important issue you should think about is getting traffic to your website. I have heard of this idea before-people who want to create an online marketplace where vendors can sell their wares-, not to mention all the sites currently available who do this, and the biggest hurdle is getting the traffic and, hopefully, enough sales, to make it worth the time and effort for you and your vendors.

Challenges that I've seen include:
- having orders placed but not fulfilled
- having vendors work around the payment process
- having shopping cart/marketplace software that handles shopping carts + shipping fees from various locations

A few other hurdles but worth the challenge :)

There are some key challenges I gonna address
Online Identity Verification: When someone visits your website, how do you know if that person is genuinely interested? Are they entering their real name and contact information? For all you know, all of the information they enter could be fake.
Solution: identifies and uses multi-layered authentication for fraud control. Some of its top features include electronic identity verification, SSN verification, instant authentication, and identity checks. Overcome these eCommerce business challenges by staying a step ahead of the hackers.
Competitor Analysis: In the super-competitive eCommerce business world, many competitors are offering similar products and services. So, how do you set yourself apart?
Solution: Conduct a thorough competitor analysis to find out what products your competitors are offering, and how much they’re selling it for. What platforms are they using to connect with customers? How are they generating leads? Do they have any promotions going on?
Customer Loyalty: Did you know that it can cost up to 5 times more to acquire a new customer than retaining an existing one?
Solution: To maintain customer loyalty, you MUST provide excellent customer service. Create positive experiences for your customers so they trust you. After all, if your customers are happy, it’s likely they’ll purchase from you again.
Product Return and Refund Policies: Never hide or try to trick customers about your return policy. Be transparent and make sure customers can easily find details about the return process. Make sure the policy is easily accessible on your website, and include FAQs to make things easier for your customer to understand. And finally, avoid words that are difficult to understand.

Prospective buyers are generally forced to depend on surrogates to assess what they are likely to get. They can consult current users to see how well a software program performs and how well the investment banker or the oil well drilling contractor performs. Or they can ask experienced customers regarding engineering firms, trust companies, lobbyists, professors, surgeons, prep schools, hair stylists, consultants, repair shops, industrial maintenance firms, shippers, franchisers, general contractors, funeral directors, caterers, environmental management firms, construction companies, and on and on. In practice, though, even the most tangible of products cannot be reliably tested or experienced in advance. To inspect a vendor’s steam-generating plant or computer installation in advance at another location and to have thoroughly studied detailed proposals and designs are not enough. A great deal more is involved than product features and physical installation alone. Such intangibles can make or break the product’s success, even with mature consumer goods like dishwashers, shampoos, and frozen pizza. To make buyers more comfortable and confident about tangibles that cannot be pretested, companies go beyond the literal promises of specifications, advertisements, and labels to provide reassurance.
