ShopFeed — Social Commerce App

Overview

ShopFeed is a mobile shopping product we designed and built around a simple observation: people already spend their time scrolling content feeds, so the store might as well live inside one. The app opens on a stream of posts, and products appear as cards embedded in that content. It suits brands and marketplaces that want discovery to feel like browsing a social network rather than searching a catalogue.

The Challenge

Conventional shopping apps assume the buyer knows what they want. That serves repeat purchases but does little for casual browsing, where the aim is to hold attention and let interest become an order on the spot. Two things that normally pull against each other had to coexist: an engaging editorial feed and a trustworthy checkout. If the feed felt like a sales page, people would leave; if buying was clumsy, the impulse would fade before payment.

Who Uses It and How

A shopper opens the app the way they open any feed, scrolls, taps a product card that catches their eye, checks the details and either adds it to the cart or keeps scrolling. Checkout happens only when they are ready. On the business side, a merchandiser or content editor publishes posts, attaches products to them and decides what appears in the feed, while a store administrator maintains the catalogue, stock status and orders.

Our Approach

We began with the interaction rather than the database. Each screen was judged by how few steps separate seeing something appealing from adding it to the cart, which is why product cards are compact and self-contained.

Content and commerce were treated as two linked data types, a post and a product, so any post can carry any number of products. We picked Flutter for consistent feel on both platforms, Firebase to run the feed and user data without a heavy backend, and Stripe because shoppers recognise it and it keeps card handling out of our own systems.

What We Built

The centrepiece is the vertical feed, where editorial posts and product cards share one flow. Cards show the essentials inline and lead straight to add-to-cart. Around it sit product detail pages, a cart, and a Stripe checkout. Because content and products are stored in Firebase, new posts and attachments go live without a new app release.

Architecture and Data

Core entities are users, posts, products, cart items and orders. A post references product identifiers, so a price or stock change updates every card that shows it. Firebase serves the feed and authentication, and Stripe manages payment collection; the app never stores full card numbers, and order confirmation is based on Stripe's payment result rather than on the app's own say-so.

Security, Privacy and Quality

Payment safety rests on delegating card capture to Stripe, which keeps the app's exposure to card data small, and on confirming payments server-side so a modified app cannot mark itself as paid. Shopper data such as addresses and order history sits behind authentication and access rules. Testing looks at the parts that cost money when they fail: cart totals, interrupted payments, repeated taps on pay, and stock that runs out while an item sits in a cart. We also check feed smoothness on modest handsets, since scrolling is the product.

Technology

Flutter provides one widget set and smooth animation, which matters for a scroll-driven experience. Firebase handles authentication, data and content delivery so the team can iterate on the feed, and Stripe sits behind checkout for payment security and compliance.

Outcome

ShopFeed offers a retailer a different front door, with discovery and purchase in the same place and a format shoppers already understand. Merchants can blend storytelling with products, and the structure lets content strategy evolve without rebuilding the shopping flow underneath.

Frequently asked questions

How much does it cost to build a social commerce app?

The main drivers are the size of the catalogue and its management tools, how rich the content feed needs to be (video, creator accounts, comments), payment methods and regional tax or shipping rules, and whether you need an admin panel.

Is Stripe safe to use for in-app payments?

Stripe is a widely used, PCI-certified payment provider, and its mobile tools collect card details in a way that keeps them away from your own servers. Your responsibility is to confirm payments on the server and protect customer accounts, which a well-built integration does.

What is the difference between a shopping app and a social commerce app?

A shopping app starts with search and categories, while a social commerce app starts with content and puts products inside it. The second approach suits browsing and inspiration, though it still needs a solid catalogue and checkout behind the feed.
