Retail software development: what we build
Ecommerce software development
Custom online storefronts with product catalogs, checkout flows and payment gateway integrations, built as headless commerce where it fits. See our ecommerce software development service for storefronts, B2B portals and marketplaces.
POS integrations and inventory systems
Centralized inventory for multi-location stock, connected to your POS, ERP and warehouse tools, so stores, warehouses and the online shop see the same quantities and prices in real time.
Order management and fulfillment automation
Order routing, ship-from-store, returns and fulfillment workflows that run automatically, with exceptions sent to your team. Intelligent automation removes manual updates between your shop, warehouse and carriers.
Personalization and recommendation engines
Machine learning models that rank products, suggest bundles and tailor offers for each shopper from browsing, purchase and loyalty data, tested against your own sales before they go live.
AI shopping assistants and chatbots
Shopping assistants and chatbots that answer product and order questions, recommend items and hand off to staff when needed. Built as AI agents connected to your catalog, inventory and order system.
Demand forecasting
Predictive models for demand, replenishment and pricing by store, channel and season, so buyers order the right quantities and stock sits where customers actually shop.
Loyalty programs and customer apps
Loyalty programs with points, tiers and personalized offers, plus native shopping apps with barcode scanning, wishlists, push notifications and in-store clienteling tools for associates.
Retail analytics dashboards
Real-time dashboards tracking sales, foot traffic, conversion rates and customer lifetime value, with one definition of each metric across stores and online.
How we build omnichannel retail software
Discovery & Audit
We map your current retail stack — POS hardware, inventory systems, e-commerce platform, and loyalty tooling — and identify where in-store and online data falls out of sync, usually the root cause of overselling and abandoned carts.
Typical timeline: 1–2 weeks
Architecture Design
We design a headless commerce architecture that keeps inventory, pricing, and customer records consistent across every channel, built to handle seasonal traffic spikes without over-provisioning infrastructure year-round.
Typical timeline: 2–4 weeks
Development & Validation
Agile sprints ship working storefront and inventory features early, with load testing against peak (Black Friday-level) traffic and PCI DSS-aligned payment handling validated before go-live.
Typical timeline: 10–16 weeks (MVP)
Deployment & Support
We launch with real-time monitoring across every sales channel, then continue tuning recommendation and forecasting models as new sales data comes in.
Typical timeline: Ongoing
Compliance & stack: PCI DSS for payment handling, CCPA/GDPR for customer data, ADA-compliant checkout flows. Typical stack: React, Node.js, PostgreSQL, Stripe, Redis, GraphQL.
Client outcome: For Urban Cart, this approach cut cart abandonment by 42% and stockout incidents by 35% by unifying inventory across stores, warehouses, and the online storefront in real time. For RetailFlow, autonomous Agentforce engagement recovered 24/7 global traffic a 9-to-5 sales team couldn't cover.
