Would you rather let go of your used stuff for free or Letgo (sell) these items in exchange for money? We’re sure you would opt for the second option.

Buy-sell apps and eCommerce apps are close cousins and we’ll be talking about important concerns you need to focus on before you build a marketplace app of your own.

Important Aspects to Consider Before You Build a Marketplace App Like Letgo

  1. Decide upon your niche

    Do you wish to develop a local selling app for selling stuff in your neighbourhood or you wish to create an app to buy and sell across cities and borders? 

    Deciding which market you want to focus on is the first step in this process. You should also decide which commodities you wish to deal with. You can go for a single category and develop an app to sell used clothes or go for a broad spectrum app.

  2. User experience

    A single online marketplace app is perceived as an app to buy stuff or an app to sell stuff online depending on whether it’s the buyer or seller.

    User experience for both cases should be taken into consideration. Buy-sell trade apps should be performance-driven and have an advanced set of features. 

  3. Fraud protection

    Fraud protection is the key to a steady market. As an entrepreneur, you should invest in customer protection reinforcement and use fraud detection algorithms.

    Both the buyers and sellers should be verified before they can register with your buying selling app. 

After considering these important considerations, it’s time to see which are the basic features that every marketplace app is composed of. 

Basic Features of a Buying and Selling App

  1. Registration

    All mobile shopping apps have this feature as a measure to register and verify users. The first step to use any buy & sell website or app is to register either as a seller or a buyer. This is why the registration feature should be easily understandable by the user. 

    Register this feature correctly when you develop eCommerce app for your business.

  2. Search filters

    This feature is a must for all online shopping apps. There is a wide variety of commodities available on a website or app. Search and sorting filters make it easier for buyers to find an item of their choice.

  3. Shopping cart

    Shopping cart contains all the items a buyer wants to purchase. This feature helps the buyer to keep a track of all the items that he found interesting on the online selling app. This must be considered when you build a marketplace app as it gives a feeling of real-life shopping.

  4. Payment integration

    Most sellers and buyers prefer the buy and sell apps online as they have the feature of payment gateway integration. This feature enables the users to choose the payment method which is the most convenient for them. Most apps provide options like e-wallet, card payment, net banking and even cash on delivery.

These were the key features that you must keep in your mind when you plan to create app like Letgo. To make your app stand apart from the crowd, our eCommerce app consultant has given a few recommendations. Have a look.

Recommended Features to Build a Marketplace App

  1. Image recognition

    This feature requires the use of advanced technology like Artificial Intelligence and Machine Learning. Letgo app enables the sellers to click a photograph of the item they want to sell and the app automatically recognizes it. It also puts the item into the relevant category from which the buyer can find it and buy it. 

    This is one feature that eCommerce app development can take much advantage of.

  2. Virtual try-on

    Using the concept of augmented reality in online shopping , this feature is helpful for buyers who wish to try an article of clothing, accessories or glasses before they buy it. This feature can help make your app the best buy and sell app if configured properly.

  3. Push notifications

    This feature works as an alarm for apps to sell and buy stuff online. They remind the customers about the items in their shopping carts that haven’t purchased yet. These also send targeted alerts and messages to the users. 

    When you create a shopping app like Letgo or eBay, push notifications can give a nice push to increase user retention.

  4. In-app chat

    This is a normal but most recommended feature for every e-business app to carry our business dealings. Buyers and sellers can communicate with each other using the in-app chat functionality. This can help them to bargain on price, discuss payment method or even schedule a meeting.

After learning about the basic and recommended features required to build a marketplace app, you must wonder about the eCommerce app development cost.
