Because, you will learn about the scope of buy and sell apps, important concerns regarding them, basic and recommended features and the estimated cost to develop an app like letgo. In fact, this blog is written with the help and guidance of our eCommerce app development consultant, who has over 12 years of experience in web and mobile app development industry. 

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.

This is how most people think. A businessman understands this psyche of the people and can make money out of it. This is the reason yard sales were so popular. Now, everything has come online. Yard sales have been converted into marketplace websites (eCommerce websites) and apps. 

These buy-sell marketplace apps have eased the process to buy and sell locally for both the seller and buyer. They are the perfect way to connect to a seller and an ideal buyer in the locality. 

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.

Let’s begin by some statistics that will give you a clear idea of the scope of this mobile marketplace for local buyers and sellers.

Scope of Online Business Apps

  • According to Statista, about 1.8 billion people purchased goods online in 2018. 
  • The global e-retail sales reached 2.8 trillion U.S. Dollars, which is estimated to show a growth of up to 4.8 trillion U.S. dollars by 2021.
  • Canada alone generated a revenue of 40 billion Candian dollars within the eCommerce market in 2018.
  • This is expected to cross 55 billion Canadian dollars by 2023. 
  • In fact, e-retail sales are expected to reach 17.5 percent of total retail sales worldwide.

Instead of competing directly against the likes of eCommerce apps like Amazon, eBay, Craigslist you could begin by starting small. Here, we will talk about some important aspects before you dive into the marketplace app development process

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.

Let see an estimate about how much it will cost to make eCommerce app.

An Estimated Cost to Build a Marketplace App Like Letgo and eBay

There are various factors that determine the cost of eCommerce mobile app development. Few important ones are

  • Features and their complexity
  • Time 
  • App development company
  • Location
  • Budget

After you have decided upon the budget, features and app development company, the cost estimation becomes easier by just calculating the hours it takes to develop a feature and what is the hourly rate of the company. 

An estimated time to develop some of the features is given in the table

1.Registration15 hours
2.Search Filters8 hours
3.Product List14 hours
4.Payment Gateway Integration10 hours

You may apply this simple formula to calculate projected mobile commerce app development cost

Estimated Development Hours * Developer’s Hourly Cost = Total Mobile App Development Cost

If you create a simple marketplace app with the features mentioned in the table above, it will take 82 hours to develop it. Suppose an app development company charges $50 as an hourly rate, then the cost to build a marketplace app can be calculated by multiplying it to the hours taken to develop it.
