E-commerce Development: Online Stores, Retail Chatbots & Loyalty

Online commerce breaks in predictable places. Online stores lose revenue to abandoned carts and overloaded support inboxes; retail chains run loyalty on plastic cards nobody carries; marketplaces and D2C brands outgrow boxed platforms the moment a workflow stops fitting the template. Momentum Squads builds custom software and AI for exactly these problems: web platforms and online stores, chat-based sales channels, loyalty systems, and the integrations that tie them into the POS, CRM, and ERP systems a retail business already runs.

For online stores and D2C brands, we build around the way you actually sell, not the way a template assumes. For Pnevmo remont we delivered a fully custom online store with its own inventory management, CRM functionality, and shipping and payment integrations. For Cloud Castle, a premium brand with more than 7,000 product SKUs across 59 stores, our conversion-focused landing redesign helped generate over $5M in revenue and attract 40,000+ authorized customers. And when commerce is the product itself, we build the platform: Felen, a global content-monetization service, sells digital and physical goods through a custom payment aggregator that routes both fiat and crypto transactions and holds up under real-time, high-load traffic.

The strongest pattern in our e-commerce work is chat as a first-class sales channel. The Telegram bot we built for that same vaping retailer handles product search, ordering, store locations, and bonus cards for 50,000+ customers and has generated over $5 million — a store inside the messenger, not an FAQ widget. On the support side, Maslotom's AI assistant answers product questions and manages orders, cancellations, and delivery updates, automating 80% of incoming requests. What we build in this space is detailed on our AI retail bots page and across our chatbot development services.

Retail chains bring different problems: loyalty without forcing an app install, price transparency on the shop floor, promotions that actually reach customers. For the Nasha Rukavychka retail chain we packed a digital loyalty card, barcode price scanner, promotions, and store finder into one chat assistant. Our café loyalty system runs QR bonuses, cashback, and referrals synchronized with Poster POS, so bonuses apply at the counter in one tap. And for Hyundai, Škoda, and Suzuki dealer networks we built a platform where high-consideration retail — test drives, financing, service booking — happens in chat, integrated with dealership stores, CRM, and service systems.

Industry context is most of the work. E-commerce software lives or dies on integrations — product feeds, POS and ERP data, delivery providers, payment systems — and on details generic teams discover late: fiscal compliance (Online Casa, our chat-based point of sale, issues fiscal receipts and handles tax reporting for small businesses), traffic peaks in promo seasons, and catalogs too large for manual upkeep. We have been building for commerce since 2017, and every figure above comes from a published case. If your store, chain, or platform has outgrown its current setup, the case studies below are the fastest way to judge whether we fit.
