OfferUp is primarily competing with CraigsList, Ebay, and Facebook marketplaces for dominance in the C2C marketplace space. As such those looking for Offerapp app development and OfferUP clones are potentially sitting on a goldmine.

How Buy/Sell Marketplaces Work

Buy & sell marketplaces like Craigslist, Ebay and allow users to buy and sell items they want to sell. Users generally list items that they are not willing to use anymore or are need of some money in lieu of the item for the sale.

Marketplaces connect both buyers and sellers by allowing sellers to place a listing of the item for sale alongwith detailed information such as pictures, warranty info, specifications and so on. Many marketplaces allows prospective buyers to demand more information before making a purchase.

Many items such as mobile phones, furniture and cars are sold through buy/sell marketplaces. C2C marketplaces are a massive industry and compliment the already $4 trillion worth of online eCommerce industry made up of B2C transactions.

C2C eCommerce is different from online shopping sites such as Amazon as the focus is on connecting buyers and sellers. Also the items being sold are used. While on online shopping sites such as Amazon, the items are mostly brand new and being sold by businesses on a continuous basis and not a one time transaction. Also, the major eCommerce sites also provide logistical solutions to the sellers in the form of logistics, shipping and so on.

How OfferUp Works

OfferUp offers all the major features of the standard C2C apps but with some additional features and key differentiation which has allowed it to grow so quickly. One of the major differentiators are that OfferUp allows users both buyers and sellers to leave reviews after their transaction.

This increases their trust in the app and subsequent can use those reviews to make purchase or selling decisions. OfferUp also restricts dangerous items such as firearms and alcohol or drug paraphernalia, which makes the platform safer for everyone. As per OfferUP, a user can start posting items for sale posts in as quickly as 30 seconds. Users can also push up their listing for a fee, similar to how an ad would function.
