I used to classify myself as a hoarder, and I still have parts from my first PC, an old school diary, and many other things my parents called junk. My problem was letting go of old stuff while I still wanted newer ones—causing storage issues. Although my dad would happily give off those things for recycling, I knew that a lot of stuff I had was in a perfectly usable state—and could quickly sell to someone who needs it.
When I couldn’t find buyers in people I knew, I turned to the internet—with websites like Craigslist and mobile-friendly options such as Offerup and Letgo apps. I sold a lot of my stuff in the first week itself—including my old CRT TV that someone wanted to use as a security monitor! I understood how much space these things were hogging after I had sold most of my old stuff off!
Are local buy and sell apps popular?
Entrepreneurs love finding solutions to common problems, which often leads them to create apps like OfferUp, LetGo, OLX, and Quikr. Operating in the US$3,284,927M e-commerce market space, the customer-to-customer or C2C vertical is showing solid signs of growth at a healthy CAGR of 5.3%. Additionally, C2C buy and sell apps benefit from rising user penetration rates of nearly 50%. The user traffic of top US-based C2C or buy and sell apps crossed 28 million in Q3 2020, showcasing a healthy growth trend that continues to grow.
How do buy and sell apps work?
Buy and sell apps like OfferUp and Letgo owe their popularity to their simplicity and the capability to help people buy and sell things they want quickly. Here’s how these two-way apps work:
- Sellers take pictures of things they wish to sell along with a description of the product. This adds the listing to the product’s appropriate category using filters.
- Buyers looking for those items can see them in their search, where they use similar filters to search for products.
- Once they have seen the sellers ad, they can ask boilerplate (pre-set) questions, negotiate the price and purchase the product directly from the seller.
A list of some popular buy-sell apps
There are dozens of buy-sell apps in the world today; however, not all have found favour with customers. Here’s a list of the top 5 buy-sell apps today:
-
- eBay
- Everyone knows eBay—the largest online marketplace founded in 1995 as AuctionWeb. The app has nearly 200 million users worldwide and offers users the option of selling by auctions and fixed-price listings. This allows sellers to get the highest possible price for their product and buyers to get a bargain when they see it, as sellers are contractually obligated to sell the item if there is a winning bid. eBay is immensely popular worldwide and made news when a gigayacht designed by Frank Mudler was sold for $168 million, making it the most expensive item ever sold on eBay.
- Craigslist
- What started as a hobby project where the founder, Craig Newmark, would describe upcoming events in the bay area through emails grew into a multi-million dollar company called Craigslist. People have been selling and buying products on Craigslist since 1998, making it one of the oldest and most iconic C2C sites around today. With over 20 billion page views per month in 2010, Craigslist is immensely popular and earns revenue through paid listings where buyers and sellers meet to sell, buy and post job listings.
- Vestiaire Collective
- Vestiaire Collective is the world’s most well-known pre-owned luxury fashion C2C portal. Growing at an immense 530% YoY, this app is exceedingly popular with those wishing to buy used luxury goods at low prices. With nearly 10 million active users and over 30,000 items submitted each week, Vestiaire Collective is exceedingly popular and made headlines when Dello Russo used their
services to sell off her personal fashion collection at rock-bottom prices. The site makes money by charging up to 25% in commissions per sale. Items sold are first shipped to the company for inspection before being shipped out to the buyer. - Letgo
Letgo started in 2015 as an app that made selling and buying things easier for the world. With over 400 million listings, 100 million+ app downloads and nearly $1B in funding, Letgo’s popularity caught the eye of their competitor—Offerup. OLX-owned OfferUp purchased LetGo in March 2020 for $120M. Letgo (now Offerup) makes it easy to buy, sell and look for items through their highly intuitive interface. - Offerup
- Launched in 2015, OfferUp is a wildly popular buy-sell app and website duo with more than 24m visits every month. With a highly intuitive interface and a large user base, OfferUp is a part of the $1.21B OLX group. Offerup has designated community meetup spots that are unique to the app. Any long-distance transaction that involves shipping incurs a shipping fee and a 12.9% charge from offerup. The app acquired Letgo in March 2020 for $120M. Both companies access each other’s customers and bring nationwide shipping to Letgo users as a combined entity.

How to create an app like Offerup and Letgo?
Creating an app has many prerequisites. Here’s what you must do before you start developing your buy-sell local app:
1. Do a market analysis and a feasibility study
Understand what you’re trying to achieve and see if the market is ready for your app. If you have created something that has no need, it might not find favour with your prospective users. It is best to create an app that is both feasible and needed by the market. Your app must fulfil the underserved need of your customers.
2. Analyze your competition
If you are a first-mover in your vertical, you may need to work harder than the others to find takers for your app. With no one to turn to for inspiration, you must develop a truly innovative idea to make it big in the app world. Analyzing your competition is a great way to see what is lacking and how your app can fill those gaps, making it a win-win situation for you and your target group.
3. Think of monetization options
Figure out how your app can make money. An app is only viable if it can make money and sustain itself in the long run. A solid, sustainable business model will help you stay in business and keep your customers happy.
4. Finalize the initial feature set for your app
Finalizing features helps you to prioritize your development needs and find a team that can build them for you.
5. Find a suitable development partner or hire a development team
Hiring the talent you need is essential to creating the app of your dreams. With an experienced development company such as Volumetree by your side, you can rest assured that your app will be all that you wanted and much, much more!
6. Choose a tech stack
Choosing the right tech stack is essential. If you do not know where to begin, it is better to use the services of a world-class development company such as Volumetree so you can choose the best tech stack for the job.
7. Finalize metrics and business intelligence
Setting up data points and business intelligence channels for your app is essential to gather valuable insights about how your users are using the app.
8. Set up marketing channels
Setting up information and marketing channels is vital so that your stakeholders can stay in the know. These channels will help you build traction and find a community of your first users.
9. Customer service/ Support
Set up support systems so your users can contact you in case they run into a problem. You can have phone support, mail support or live chat within the app. You can also use this channel to figure out what your customers need the most from the app.
10. Maintenance/updates
Building an app is not the end of the game. Ensure that you proactively set up updates and maintenance cycles so that you can address any issues your quality team did not find in their tests.
