Experts understand successful marketplace apps to scale both supplyand demand-side at the same time. Once trust and sufficient liquidity are achieved, the efforts of marketplaces shift to fostering transparent and efficient transactions. Buyer-to-seller chat drives more transactions by closing the gap between a buyer’s desire for a product or service and the ability to purchase it in the moment, while allowing sellers to reach buyers when intent to buy is highest.
And yet, once marketplaces have a foothold in local markets, the competition is fierce and the goods and services are mostly undifferentiated. Differentiation must come from the best user experience.
There’s no better way to build a differentiated user experience or connect buyer and seller than in-app messaging. Real-time messaging connects your marketplace’s buyers and sellers across multiple apps and platforms so they can engage and inform both supply and demand to transact more quickly. This creates more efficient transactions for the marketplace platform.
Jeff Jordan, former eBay and current General Partner of Andreessen Horowitz, said that to manage a marketplace well you need to “Maintain complete transparency in the marketplace so that participants (especially buyers but sellers too) have perfect information on products and their pricing […] Focus heavily on safety so the marketplace is as safe as possible to create the trust required on both sides.”
In-app messaging accomplishes exactly that. It creates transparency and trust between buyer and seller about the products being sold. Thus informed buyers will convert more quickly and sellers will be better equipped to inform buyers about their product, how to purchase, and how to receive it.
The diagram above demonstrates how messaging contributes to more transactions over time. By connecting supply and demand through messaging, marketplaces accelerate buyer decision, build trust, and ensure that buyers and sellers that buyers and sellers can communicate successfully with chat through a channel that people already love to use. This brings successful communication to scale, helping engagement and retention. These key metrics – retention and engagement – are the fuel for KPIs like customer acquisition and help inform customers about products quickly, complementing network effects in your product. All this to successfully book more transactions over time.
Key question: Why in-app chat? And not SMS, calls, or other communication tools?
Anytime a user needs to leave your marketplace app, your are losing key intelligence on how buyers and sellers communicate and complete transactions. SMS and calls are the quintessential examples of how many marketplaces deliver omnichannel communication to buyer and seller. Both, however, pull users out of your app, require costly call masking, and push costs onto your buyer and seller. Not to mention the cost of email for marketplaces servicing international customers.
Key player: Seller – “The supply side is king,” Andrew Chen
Over the short 12 to 15 years that two-sided marketplaces have emerged as incredibly powerful business models, growth experts have reached a general consensus that the “supply side is king.” By providing tools for sellers to sell more quickly and efficiently, marketplaces provide significant value to the supply side and draw them to the marketplace platform. As supply aggregates in a marketplace, buyers join too. Buyers, of course, are equally important. But sellers and suppliers face deeper challenges in a competitive market, so marketplaces are apt places to provide excellent tools and products to make their experience easier.
Key use-case: Buyer-to-seller chat
Buyer-to-seller chat connects the supply- and demand-side of a marketplace directly without intervention from the marketplace platform.
That means buyers and sellers can inform each other, resolve issues that arise, and more effectively buy or sell – all independently from omnichannel customer service or a team of agents required to address support tickets. By empowering buyers and sellers to communicate transparently, platforms empower their marketplace to grow organically. In fiercely competitive local markets, buyerto- seller chat brings a differentiated user experience and allows sellers who offer the best service a competitive advantage.
1. Increase user transactions, gross merchandise value, and average order value by increasing user engagement through dynamic communication
2. Accelerate new user acquisition by growing the value and scale of the app through user retention and creating advocates
3. Understand how buyers and sellers communicate through chat data to optimize communication patterns, create more efficient interactions, and utilize the data for new business roll-outs
In order to prove the success of in-app chat, it’s crucial to set a benchmark for comparison before and after the successful launch of chat.
On both the Buyer and Seller apps, analyze the following metrics more deeply to understand how chat affects transactions and user engagement.
These KPIs are important for a range of marketplaces, but they may not apply to all marketplaces.
Transactions & AOV
The average time it takes for a buyer and seller to transact (in-app message payments, second-hand goods market)
How many inquiries on average before a transaction is successful
Total revenue divided by the number of orders
1. To determine an appropriate growth metric:
3. For sellers, you might determine the core action to be a sale and frequency to be shorter – weekly. Then your growth metric is weekly active sellers
4. Once you’ve determined the appropriate growth metric, then track user retention by cohort according to the frequency of the core action. In this example, you would track buyers by monthly cohorts and sellers by weekly cohorts. It may take either historical data or additional time to determine your retention benchmark.
Once you have a full understanding of your current benchmark for these and other KPIs, you will be able to measure the effects of in-app chat accurately.
From the incremental trends of the graph you can see that as user engagement increased, Company A’s end-user had more opportunities leading to increased transactions.
By leveraging chat data, Company A is rolling out new business initiatives such as live commerce, community chat, and customer-to-customer messaging – utilizing chat as its main communication tool.
Increased user acquisition
As chat familiarity grew and user experience improved transactions, this resulted in higher MAU.
By analyzing chat data, Company B was able to save 75% of the cost of calling, SMS, and outsourced communication tools by replacing them with buyer-to-seller chat – becoming the company’s number one communication channel. With greater engagement and retention using in-app messaging, their user acquisition saw a significant up-tick
Marketplaces benefit from features that connect users conveniently, remind users of outstanding messages or offers, and help sellers demo or share rich media about their product. Since marketplaces connect buyers and sellers across iOS, Android, or Web, it’s crucial that in-app messaging support multiple platforms. Sellers want to know if they’ve missed any messages or to be notified when a buyer is interested at the right time.

Creating a channel according to interactions between a buyer and seller, especially a seller who manages multiple listings, emphasizes the relationship between the buyer and seller. This is frequently the case with marketplaces for big ticket items like homes or rental properties, or for industries that highly depend on relationships. As a trade-off, when multiple listings, items, or products are referenced in a single chat, it can be difficult to pinpoint which conversation is tied to which listing.
For marketplaces, it is crucial to the app’s chat flow to know when it should open a chat channel. Depending on the type of marketplace, you can initiate chat and create a channel through a seller or product listing. There are tradeoffs for both.
Perfect for marketplaces with big-ticket or highly differentiated items like home or rental properties, or when the seller relationship matters Challenging to track multiple listings, items, or products in a single chat
Perfect for marketplaces with a higher volume of products and transactions because it allows users to communicate within the context of a single product. Users can then make or accept offers, ask or answer questions without needing to track context. This de-emphasizes the buyer-to-seller relationship in favor of product context.

Channel creation according to item listing
Creating a channel according to a product or item allows buyers and sellers to communicate within a specific context. All actions – make an offer, inquire, and others – are therefore tied to the specific product and can be easily rendered in the chat view.
By triangulating chat between a buyer and seller through a product, the marketplace loses the personal quality or transaction based on relationship. This can be desirable depending on the marketplace or context.
To keep track of all conversations about a single product, assign a unique ID for the product as metadata for each chat channel. By using the message retrieval API, marketplaces can see all conversations around a certain product.
1. See previous chat history and check the unread message counts by clicking the badge in the top-right corner or search for products to buy.

By connecting supply and demand with chat, marketplaces can empower buyers and sellers to create more informed and efficient transactions at scale. Even in early-stage marketplaces, building trust is crucial to retain both supply and demand, and chat can help them scale liquidity. In later stage marketplaces, when local competition is fierce and differentiation is challenging, in-app messaging helps companies differentiate with the best service and user experience.
