What you need to know about auction marketplace


It is a multi-sided platform that connects sellers (which compete for a service/product) and buyers together. But what is the difference between auction marketplace and common marketplace? In fact, the first one does not have the fixed price, so products and services cost much cheaper. In this case, the buyer bids, but eventually the goods are sent to the person who offered the highest amount of money. The process is completely transparent to both sides.

Different types of the online auction:

Increment auction (#1)

The essence of this type of auction is that the rate increases by a certain number. That is, when the maximum rate is overlapped, the current auction bid must increase by at least a given number.

For example, you can look at automatic bidding on Ebay. So, if the current price of the item is about $0,01 to $0,99, that bid increment must be about 5 cents. Another example: if you sell something and say that minimal price for it is twenty dollars and the increment bid is ten dollars. When the bid placed at the fifty dollars level, it automatically increases by ten dollars. After this, the minimum bid will be sixty dollars.

Automatic auction (#2)

One of the easiest methods to bid. This method is based on the maximum buyer's offer. The buyer offers the maximum amount of money that he is willing to pay for a certain product. After that, on his behalf, a bet is placed in the system. If another bidder invites more money, the previous entry is deleted and a new maximum bid occurs in its place.

Reserve price auction (#3)

In the latter case, the buyer says the minimum price to buy. Usually, this price is hidden, so people participating in the auction can only watch the result. When reserve price is met, a bid with the highest price is carried out.

For example, if you sell a certain product with such conditions: reserve price - thirty dollars, and starting price - five dollars. When buyers start bidding at $5 and in the end, the product does not reach $30, your product will not be sold.

Online auction website


Many people think that the auction site must be related to the retail industry. But it is not always true.

Such type of marketplaces is also connected with restaurant and food, real estate, finance, automotive, logistics, and art industries.

Here are some real examples of Online Auction Marketplaces for you:

Ensuring security and transparency of transactions

Security and trust

Of course, to increase the number of users, you need to work on the security system. After all, the level of trust and protection plays a very large role.

To sell expensive things, provide a guarantee of protection. For example, Worthy provides its customers with full insurance up to ten thousand dollars. Salvagebid offers a guarantee that the purchase will be completed in any case (this mechanism is provided by the system of guarantee deposits).


Provide verification of users of the online platform, which should include a field for entering information about the credit card and ID.


It is very convenient when people can leave feedbacks to each other.

Obligations of participants

This is the most convenient way to get rid of scammers. Provide participants with a list of various rules (on prohibited items, on the obligation to pay for goods, on the possibility of a refund, etc.).


You should take in mind that if you want to develop your online auction site - develop a common logic and functionality for your marketplace to attract the relevant audience and ensure the security of transactions.
