Statista reports that by the end of 2021 the revenue of the e-commerce market will reach US$ 2,723,991 million. Furthermore, it's expected that its yearly growth rate will be 6.29% by 2025, and the size of the market will grow to US$ 3,477,296 million.
The common feature of the apps like Offer Up and LetGo is that they allow a seller to give goods free of charge. It's a great way to get rid of some small items, which you can't sell on eBay because the service charges a commission for every transaction. Let's take a closer look at these applications and try to understand the reason for such popularity.
LetGo app allows you to sell stuff online in a particular area quickly and easily. The service is so easy to use you can sign up via a Facebook account. Social registration allows checking the data of all users since the system cares about the platform's security. Customers and sellers communicate in the chat inside the app. You can upload photos of the items you want to sell immediately using the built-in camera in the app. So if you decide to create app like LetGo, you may use some of its features.
OfferUp app is the biggest marketplace for local customers and sellers. The app provides security because it allows every user to build their reputation on their profile page. Just like on eBay, users can rate a person after a deal. As well as that, customers can join their service TryYou and add their ID to prove the authenticity of a profile. The system provides a secure chat but the deals are conducted personally.
The OfferUp developers claim that their users spend approximately 25 minutes a day in their app, just like for Instagram and Snapchat. The use of mobile apps is growing in all business areas and it's a great opportunity for a P2P e-commerce market to create an app to sell products. The secret of success is simple: the easier and more comfortable you connect a customer and a seller is, the more successful your app will be.
What is worth mentioning is that OfferUp acquired LetGo in September 2020. As a result, the strengths of these marketplaces are merged, which allows buyers to make more deals and sellers to attract more customers and sell faster. There are other platforms on the sell and buy app market, such as ThredUp, Depop, Poshmark, Craigslist, Carousell, Mercari, Bookoo, and they function in much the same way.
The Business Model of Apps like LetGo and Offer Up
OfferUp and Letgo are aimed at selling and buying second-hand goods. These buy-and-sell apps have an identical business model focused on income generation from the advertisement. They don't take a fee for creating a profile, registration, and even a deal.
If you want to learn how to build an app like LetGo, we suggest you consider some of these monetization strategies.
If customers can pay via your app, you can charge a fixed price or a percent of every deal. For instance, it's easy to do with some third-party services like Stripe.
What is meant here is the ability to buy some special offers, or sellers can pay to place their ads at the top.
Your service can also be a mediator allowing sellers to expand the trading territory.
It's a good opportunity to publish action offers, special offers, and a system of internal recommendations.

Basic Features of a Buy-And-Sell Apps
To follow an existing LetGo model is undoubtedly the best way to create your mobile app. However, don't forget that it should be original and contain some particularities. Therefore, you need to analyze competitors from your domain and find uniqueness that will be your market advantage.
Now, when we know how local apps for buying and selling work, let's see what basic functionality we need to include in our own model.
Bear in mind that the search should be conducted based on the customers' location. So, add an option to extend or constrict the search band. It’ll be easy to perform as almost all modern smartphones have a built-in GPS utility.
Registration via social network
All the best apps to sell stuff locally have this feature. It increases users’ reliance on your service and simplifies the identity verification process. Besides, they don’t need to enter their data manually because all information will be pulled automatically from a social network.
The personal data of sellers and buyers will be shown as well as all items for sale, a list of addresses and cards. Users also must be able to remove their profile and delete a card.
Advanced filters are needed to make the search process easy and fast. You can divide all goods by categories, groups, price, size, location, and other criteria to minimize shoppers' search time.
Each listing can have two options: choose a good from the list (by color, smell, and other details) if the seller has some similar goods with different variations or enter one's own one. Also, it would be nice to add a size chart here.
This feature allows taking photos in the app and uploading them immediately. A pleasant addition that the sellers would appreciate is the opportunity to edit photos, cut them down, adjust brightness and contrast.
This is one of the most popular and useful features for such apps. With it, it's much easier for users to discuss deals' details and communicate.
Multi-language and currency support
If you want your app to work in multiple countries, it must support relevant currencies and languages.
It's a cost-effective feature that'll allow your users to stay informed about all novelty, updates, changes and receive notifications of new messages in the chat.

Compare the prices
It’s an excellent opportunity for users to choose the best items – quick and easy.
Offer hot deals
The ability for a seller to offer hot deals, discounts or coupons is great. If you make this feature one that has to be paid for, it can bring you some extra income.

Scan photo feature
With the help of this feature, your app can give recommendations about how to fill in article descriptions and categorizations. You can also track the quality of the uploaded photos. On various forums, customers complain about the quality of pictures or that they are fake. Some services solve such issues by deactivating a deal and ask a seller to add at least one live photo of an item.
Agree with outside delivery services to provide your users with the best UX and save transaction time.
Comments and rating
The feature helps build the reputation of customers and soft articles according to a seller's rating. At the same time, the feature protects customers from unreliable merchants.
Inbuilt payment solution
When customers use your service for the first time, it asks for credit card information and phone number. After that, the users enter an email, and a unique code is sent to it to confirm all their data. So it isn't necessary to enter it every time using the service.
Steps on How to Make a Buy-And-Sell App
Here are the main steps you should undertake to understand how to make an app to sell things effectively.
1. Think about a crowd-pleasing name
Your app first should be attractive with its name. Users see the title first, and it should be short and topical. There are different brand name generators, and they can help you choose a perfect name for your future app. Other essential tips you should follow are app’s title size, semantic load, and expectations of a target audience.
2. Engaging UI/UX is a must
Good-looking UI/UX isn't a thing you can ignore. Indeed, beautiful images and a convenient user experience mean a lot, and your potential consumers will appreciate it. As you create a buy-and-sell app, it should have a simple and intuitive UI and UX, as users want to see a familiar model of an app like this.
3. Add a shopping cart
People can buy various products using your app and should have an opportunity to add products they choose to a virtual shopping cart. When buyers make a list of products they need, they can go to this cart and proceed to the payment page or choose payment on delivery, according to their requirements. A shopping cart makes it possible to sort all products wisely.
4. Payment gateway integration
Choose the most appropriate payment gateway for your buy-and-sell app – whether it’s PayPal, Braintree, Stripe, or another payment system. If you have difficulties choosing the suitest one, study the market and your competitors, review successful solutions, etc. Also, pay attention to local governmental requirements and don't forget about payment processing safety.
5. Think about an adequate promotion
If nobody knows that your product exists, you’ll gain nothing. That is why you should create a promotional plan to let everybody know about your app. For example, use Google ads on different websites, although it is a rather expensive service, you’ll be able to increase the interest of potential customers. Also, personalized bussiness apps can be used as an effective way of app promotion. If you apply a serious approach, you’ll achieve good results. Your app for buying and selling will become competitive and quickly gain the lead.

Fraud Protection in Local Buy-And-Sell Apps
If you want to gain customers' loyalty and trust, when you discover how to create apps like Letgo and OfferUp, make sure you do your best to protect them from fraud.

Fraud protection is an important factor while working with merchants used to a partnership with highly regulated payment processing networks in buy-and-sell apps. Investing in it now, targeting the cooperation with merchants and mobile network providers is a well-considered step for long-term market growth in the future.

However, when you start to build your own app for selling and buying, remember the essential flow. Define its core and distinctive features, correctly design the MVP model, and find a qualified development team – and then you’ll succeed.

Wow, this is one of the best tutorial article I am really pleased to find many useful help here. Thank you very much.
Offer-up buys let-go but snubs all of its let-go users Offer up purchases let go but then provides no mechanism for let-go users to transfer advertisements from their old selling app to the new one. Hundreds upon hundreds of thousands of advertisements would have to be completely retyped and reposted And rephotographed in order to use the new OfferUp app. Even though many users have asked for some transfer mechanism to transfer their ads the company refuses to accommodate the users it just purchased in this merger. A group of users is considering getting together and writing a new app with the ability to copy all of the ads off both let-go and OfferUp and import them into a new selling app which has not yet been named
