Classifieds Software for Buy-and-Sell Marketplaces

Your own classified app, where people list what they have, find what they want and agree the deal. How they agree it is the decision most quotes skip, because a chat thread, a phone call and a WhatsApp message are three different products. It is designed and built new for your market by a team that has built buy and sell apps many times. Most first releases go live in about 30 days.

  • Chat, call or WhatsApp

How it works

A sale, start to finish.

Every classified app lives or dies on how fast somebody gets from a photo to a deal. This is the path your users take, and the part of the app that carries each step.

Very professional. Our project was quite complex and they covered all the aspects. Appkodes did an amazing and professional job developing and creating our Apple and Android apps. I was positively impressed with the communication you can absolutely trust on what they say.

Inside the app

Everything a marketplace needs, from day one.

A classified app looks simple from the outside, because it is a photo, a price and a message. What makes one work is everything underneath, and it is the part most first releases get wrong.

This is the machinery we build into yours, shaped around your categories and the way your market deals. Each piece is designed and built new for you, by a team that has built buy and sell apps many times.

Get a free costed plan
  • One account, both sidesThe same person sells a bike on Monday and then buys a desk on Friday. One profile, one inbox, one set of ratings. Sign-up is a phone number and an SMS code, because email is not how every market works.
  • Listings in under a minutePhotos, category, condition, price and location, with fields that change by category and by country. A car asks for mileage, a flat asks for bedrooms, and a plumber asks for nothing but an area.
  • Search that finds itFilters for category, price, distance and condition, and results ranked in the order you decide. Standing searches watch for a buyer and alert them the moment a match is posted.
  • How people get in touchChat keeps the conversation and the phone number on your platform, which is what most marketplaces want. Other markets want a call button and nothing else, so that is a decision rather than a default.
  • Offers and swapsBuyers name a price or propose an exchange, and the seller accepts, counters or declines it. Haggling is how most of these deals actually happen, so it belongs inside the app.
  • Where the listings come fromAn empty marketplace has nothing to search, which is the first problem every one of these faces. So listings arrive from sellers, from dealer feeds and from bulk uploads, with duplicates caught on the way in.
  • Listings that stay trueA sold item still listed is the fastest way to lose a buyer for good. So listings expire, sellers get asked whether it is still available, and silence pauses the ad.
  • Promotions that earnSellers pay to move a listing to the top, mark it urgent or feature it on the home screen. You set the plans, the prices, the durations and what happens when a payment fails.
Additional features

The extra features you may need.

The core app covers listing, search, contact and offers. These are the extras clients ask for most often, and each one is designed for your app and priced in your costed plan.

  • Buy now checkout

    In-app payment and delivery for fixed-price items.

  • Call and WhatsApp buttons

    One tap from a listing to a phone call or a WhatsApp message.

    Contact details without a sign-up, where your market expects it.

  • Bulk and feed imports

    Dealer feeds and spreadsheets, read in and deduplicated.

  • Availability checks

    Listings ask the seller whether it is still there, and pause when nobody answers.

  • Swaps and exchanges

    Item-for-item trades, with swap requests in chat.

  • Reviews and ratings

    Two-way ratings that build trust over time.

  • Image moderation

    Objectionable photos caught before they go live.

One app type, many markets.

  • Cars and bikesMake, model, mileage and inspection reports.
  • PropertyRentals and sales with maps and floor plans.
  • ElectronicsPhones, laptops and gadgets with condition grades.
  • FashionPre-loved clothes, sizes and brands.

  • Duplicate detectionThe same advert reposted, or one number behind twenty listings, caught on the way in.
  • Stale listing checksSellers get asked whether it is still available, and silence pauses the ad.
  • Reports and blocksUsers flag listings and people, and your team acts from one screen.
  • Private chatBuyers and sellers talk without sharing phone numbers or emails.
  • Seller ratingsEvery deal adds to a public track record.

Questions

Before you build.

Not here? The costed plan answers the rest, for your app.

Can it work like OLX or Letgo?

Yes. Listing, search, chat, offers and paid promotions all work the way people expect from the big classifieds apps. The difference is that it is your app, with your brand, your categories and your rules, designed and built new for your market.

Do buyers have to create an account?

That decision is yours, and it shapes the product more than most people expect it to. An account requirement gives you a user list, ratings and a record of every conversation. Open browsing gets far more people to a phone number, which is what a trades directory wants. We build whichever one you pick, and your admin switches it per category later on.

Can sellers be contacted by phone or WhatsApp instead of chat?

Yes, and in plenty of markets it is the only thing people will ever use. A listing carries a call button and a WhatsApp button that open the phone directly. In-app chat still exists alongside them, where you want the conversation kept on your platform. Tell us which your buyers actually use and the listing screen gets built around it.

How do I fill a marketplace that starts empty?

The honest answer is that this is the hardest part, and it is a plan rather than a feature. What the app gives you is every route in. Sellers post their own listings, dealer and partner feeds arrive, and spreadsheets upload a thousand at a time. Duplicates get caught on the way in, so an import does not fill the app with the same advert nine times. We scope those routes with you before the build starts.

Is this a ready-made app?

No. Every app we build is designed and built new for its client. We have built buy and sell apps many times, and that experience is what lets us fix the scope, the price and the launch date before we start.

How long does it take?

Most first releases go live in about 30 days. Larger apps, or ones with several add-on modules, take longer. Your costed plan fixes the scope and the exact date in writing.

Which platforms do I get?

An iOS app, an Android app and a website for buyers and sellers, plus a web admin panel to run the marketplace. Some clients start with fewer and add the rest later.

Which languages and scripts do you support?

Whichever your market reads, and that includes right-to-left scripts such as Arabic, Dari, Pashto and Urdu. The apps, the website and the admin are all translated, not just the buyer side. Prices show in local currency, and categories differ per country. Right-to-left is real layout work rather than a translation file, so it belongs in the scope from the start.

Can I launch in more than one country?

Yes. The app supports several languages and currencies, with categories and locations set per country.

Can buyers pay inside the app?

Yes, with the Buy now module. Buyers pay by card or wallet, sellers get paid out, and you take a commission on each sale.

How do you keep scams and bad listings out?

The queue is the first line, with image moderation, user reports and seller ratings behind it. Duplicate detection catches the same advert reposted, and the same phone number behind twenty listings. Listings that go stale get an availability check, and they pause themselves when nobody replies to it. Your admin team decides how strict each one is.

Which technology do you use?

We choose the stack for your project, usually native or cross-platform mobile apps with a scalable backend and real-time chat. Your costed plan lists exactly what we will use, and the code is yours.
