How a Retail Chain Unified Its E-Commerce and In-Store Operations With Custom Apps

The retail industry is undergoing its most significant structural transformation since the advent of the shopping mall. Consumers today expect a seamless experience across every channel — browsing online, purchasing in-store, picking up curbside, returning through a mobile app — and they have little patience for retailers who cannot deliver that consistency. For mid-sized retail chains operating dozens or hundreds of physical stores alongside a growing e-commerce presence, the challenge of unifying operations has become an existential priority. This case study examines how Summit Home & Living (a composite profile representing a typical omnichannel retailer), a chain of 127 home goods stores across the United States, used a low-code platform to unify its e-commerce and in-store operations, achieving a 35% increase in omnichannel revenue, a 52% reduction in inventory discrepancies, and a 28% improvement in customer satisfaction scores.

The Omnichannel Disconnect: Two Businesses Operating Independently

Summit Home & Living had grown from a single store founded in 1987 to a chain of 127 locations across 22 states, with annual revenue of $1.6 billion. The company had launched an e-commerce website in 2018, but the online channel operated largely independently from the physical stores. The result was a fractured customer experience and significant operational inefficiencies that were eroding margins and market share.

Inventory visibility was the most painful problem. The company's e-commerce platform and its store point-of-sale (POS) system were completely disconnected. When a customer visited Summit's website to check if a product was available at their local store, the inventory information was frequently inaccurate. The website showed stock levels based on warehouse inventory and manual store-reported counts that were updated only weekly. As a result, shoppers would arrive at a store expecting to find a product that was out of stock, or would place an online order only to receive a "product unavailable" notification three days later. Customer service teams estimated that 22% of all customer complaints were related to inventory accuracy issues.

Order fulfillment was fragmented and inefficient. Summit offered three fulfillment options — ship-to-home from the warehouse, buy-online-pick-up-in-store (BOPIS), and buy-online-ship-from-store. But each option was managed by a different system with different processes. The ship-from-store program, in particular, was struggling. When an online order was routed to a store for fulfillment, store staff received the order through a clunky interface that did not integrate with their regular workflow. The order had to be manually picked from the sales floor, processed through a separate shipping station, and tracked in yet another system. The average time to fulfill a ship-from-store order was 4.2 hours, and 8% of these orders were never fulfilled because they were lost in the process.

Customer service was inconsistent across channels. A customer who purchased an item online could not return it at a store — at least not without a lengthy process involving phone calls to a separate customer service center. Store staff could not see online purchase history, and online customer service agents could not see in-store transactions. Customers were forced to repeat their information every time they switched channels, creating frustration and driving customers to competitors who offered a more seamless experience.

Perhaps most alarming, Summit was losing market share to competitors who had already solved these problems. Target, Walmart, and Best Buy had invested billions in omnichannel infrastructure, and smaller, more agile competitors were adopting unified commerce platforms that gave them comparable capabilities at a fraction of the cost. Summit's leadership recognized that the company needed to act decisively or risk becoming irrelevant in its core markets.

Why the Traditional Approach Would Not Work

Summit's IT team initially recommended a unified commerce platform from a major vendor — a solution that would replace the existing POS, e-commerce platform, order management system, and inventory management system with a single integrated suite. The estimated cost was $8.5 million for software licenses and implementation services, with a deployment timeline of 18 to 24 months. The annual ongoing cost was projected at $1.2 million.

The business case was compelling on paper, but the leadership team had concerns. The 18-month timeline meant another holiday season would pass before the solution was operational. The rigid architecture of the platform would require Summit to adapt its processes to the software rather than the other way around. And the cost would consume the entire IT budget for the year, leaving no resources for other digital initiatives.

A low-code alternative emerged during the evaluation process. Summit's head of digital transformation had seen low-code platforms used successfully in other industries and proposed a different approach: rather than replacing all systems simultaneously, use a low-code platform to build an integration and workflow layer that connected existing systems and added the missing omnichannel capabilities. The estimated cost was $2.1 million, the timeline was 6 to 9 months, and the platform could be adapted continuously as requirements evolved.

The Unified Operations Platform

Summit selected a low-code platform and launched Project Unified in February 2025. The project was organized around four application modules, each addressing a specific dimension of the omnichannel disconnect.

Module 1: Real-Time Inventory Synchronization

The first and most critical module was a real-time inventory synchronization system. The low-code platform connected to Summit's existing POS system (a legacy on-premises solution), the e-commerce platform (Shopify Plus), the warehouse management system (a third-party WMS), and the ERP system (Microsoft Dynamics 365). Through these connections, the platform created a unified inventory view that updated in near real-time across all channels.

Key capabilities included:

• Real-time stock adjustments: Every POS transaction, online order, and warehouse shipment updated the inventory view within seconds
• Inventory allocation engine: Products were intelligently allocated between channels based on demand patterns, store proximity to customers, and inventory velocity
• Safety stock optimization: Dynamic safety stock levels were calculated for each store-SKU combination based on historical demand, lead times, and forecast variability
• Inventory health dashboard: Store managers and buyers could see slow-moving inventory, overstock situations, and stockout risks in real time
• Automated replenishment: Purchase orders were generated automatically when inventory levels fell below thresholds, with suggested quantities optimized for each store

"The first time I opened the inventory dashboard and saw every store's stock levels updating in real time, I almost cried," recalled Summit's vice president of supply chain. "For 15 years I had been making inventory decisions based on data that was one to two weeks old. Suddenly I could see what was actually happening, right now, across the entire company."

The inventory synchronization module was built by a team of three professional developers and two supply chain analysts in eight weeks. It went live in April 2025 and immediately began improving inventory accuracy. Within the first month, the discrepancy between system inventory and physical inventory counts dropped from 12% to 3%.

Module 2: Unified Order Management

The second module addressed the fragmentation of order fulfillment. The low-code team built a unified order management system that consolidated orders from the e-commerce website, mobile app, phone sales, and in-store kiosks into a single routing and fulfillment engine.

Order routing was optimized based on multiple factors:

1. Inventory availability: Which locations have the product in stock
2. Customer proximity: Which location is closest to the customer's shipping or pickup address
3. Fulfillment cost: The total cost of picking, packing, and shipping from each potential location
4. Store workload: Current fulfillment queue depth at each store, to prevent overwhelming staff
5. Profit margin preservation: Preference for fulfilling from locations where the margin impact is most favorable

The system supported all major fulfillment methods — ship-to-home, BOPIS, curbside pickup, ship-from-store, and buy-online-return-in-store — through a single interface. Store staff accessed fulfillment tasks through a purpose-built mobile application that showed them exactly what to pick, where to find it in the store, how to pack it, and which carrier label to use.

Ship-from-store turnaround improved dramatically. The average time from order receipt to package handoff to the carrier dropped from 4.2 hours to 38 minutes. Store-level fulfillment accuracy reached 99.5%. The percentage of online orders fulfilled from stores — rather than from the central warehouse — increased from 15% to 40%, reducing last-mile delivery costs by $1.8 million annually.

Module 3: Omnichannel Customer Profile

The third module addressed the customer experience fragmentation. The low-code platform created a unified customer profile that aggregated purchase history, browsing behavior, loyalty program participation, and customer service interactions across all channels. This single customer view was accessible to store associates through a tablet application and to online service agents through a web interface.

With the unified profile, store associates could:

• View a customer's online and in-store purchase history during a store visit
• Process returns for online purchases without requiring a receipt or initiating a phone call
• Access the customer's saved shopping lists and wish lists to provide personalized recommendations
• See loyalty status, reward balances, and personalized promotions
• Record customer preferences and notes for future interactions

The unified profile also enabled personalized marketing across channels. A customer who browsed a specific product category online without purchasing could be offered a targeted promotion via email or through the mobile app. A customer who purchased a mattress in-store could receive follow-up recommendations for bedding and pillows through any channel. Cross-channel marketing campaigns were coordinated through the platform, ensuring customers received consistent messaging regardless of how they interacted with the brand.

"Before Unified, we treated our online customers and our in-store customers as completely separate groups," said the chief marketing officer. "The reality is that most of our best customers are both. They research online and buy in-store, or they buy in-store and then reorder online. The unified profile helped us recognize and reward that behavior instead of treating it as two separate relationships."

Module 4: Store-Level Dashboard and Analytics

The fourth module provided store managers and corporate leadership with actionable analytics that connected e-commerce and in-store performance. The low-code dashboard replaced a confusing array of reports from different systems — POS sales reports, e-commerce analytics, inventory reports, customer satisfaction surveys — with a single, integrated view of each store's omnichannel performance.

Key dashboards included:

• Omnichannel store scorecard: Each store's performance on sales growth, omnichannel revenue, BOPIS volume, ship-from-store volume, inventory accuracy, and customer satisfaction
• Channel contribution analysis: How each channel — in-store, online, mobile, phone — contributed to total revenue and profit for each store's market
• Customer journey analytics: Visualizations showing how customers moved between channels, with insights on the most common paths to purchase
• Inventory optimization recommendations: Actionable suggestions for each store based on inventory data, such as which products to mark down, which to reorder, and which to transfer between stores
• Real-time operational alerts: Notifications when inventory levels dropped below thresholds, when BOPIS orders were approaching the pick deadline, or when customer satisfaction scores in a store declined significantly

The analytics module was built by two developers in six weeks, with dashboard designs contributed by a store manager who had trained as a citizen developer. "Having a store manager design the dashboard was brilliant," the VP of operations said. "She knew exactly what information her peers needed and how they wanted to see it. The adoption rate among store managers was near 100% because they felt the tool was designed for them, not for corporate."

Measurable Results: The Unified Commerce Transformation

Project Unified was deployed across all 127 stores over a period of seven months. The first three months focused on the inventory synchronization and order management modules, which were deployed in waves of 20 stores per week. The customer profile and analytics modules followed in months four through seven. Results accumulated steadily as each wave went live.

Metric	Before Project Unified	After 12 Months	Improvement
Inventory accuracy (system vs. physical count)	88%	97.5%	79% fewer errors
Omnichannel revenue (% of total)	12%	34%	183% increase
BOPIS order volume	4,200/month	28,000/month	567% increase
Ship-from-store fulfillment time	4.2 hours	38 minutes	85% reduction
Online return in-store processing time	12 minutes	2 minutes	83% reduction
Customer satisfaction (omnichannel experience)	3.2/5	4.4/5	38% improvement
Store-level out-of-stock rate	8.5%	2.8%	67% reduction
Last-mile delivery cost reduction	Baseline	$1.8M annual savings	22% reduction

Revenue growth was the most impactful outcome. Summit's omnichannel customers — defined as those who shopped through at least two channels in a 12-month period — spent an average of 3.4 times more than single-channel customers. By making the omnichannel experience seamless, the company increased the proportion of omnichannel customers from 22% to 41% of the total customer base. This shift drove $47 million in incremental revenue and contributed to a 35% increase in same-store sales growth compared to the prior year.

FAQ: Common Questions About Retail Low-Code Platforms

How does a low-code platform handle the transaction volume of retail peak seasons?

Retail systems face extreme load spikes during Black Friday, holiday sales, and promotional events. Summit's low-code platform was architected with auto-scaling cloud infrastructure that could handle peak loads 10 times higher than normal daily volumes. During the 2025 holiday season — the first peak period after Project Unified went live — the platform processed 187,000 orders on Black Friday alone, supporting 42,000 BOPIS pickups and 15,000 ship-from-store orders without any performance degradation or downtime. The auto-scaling capability meant that Summit paid only for the infrastructure it actually used during normal periods while having virtually unlimited capacity during peaks.

Can low-code applications replicate the functionality of a dedicated POS system?

The low-code platform was not used to replace Summit's POS system — it was used to connect and extend it. The POS remained the primary system for processing in-store payments, managing cash drawers, and handling refunds. The low-code platform added capabilities that the legacy POS could not provide: real-time inventory synchronization across channels, unified customer profiles, omnichannel order management, and advanced analytics. This approach — extending rather than replacing — allowed Summit to achieve omnichannel capabilities without the risk and disruption of a complete POS replacement. The company plans to eventually migrate to a modern POS, but the low-code platform has given it the flexibility to make that transition on its own timeline rather than under competitive pressure.

The Citizen Developer Effect: Store Managers Building Store Solutions

Following the success of Project Unified, Summit launched a formal citizen developer program to extend the platform's value beyond the original four modules. Twenty-five store managers, regional supervisors, and supply chain analysts completed low-code training and earned certification as citizen developers. Within six months, they had built 31 additional applications addressing specific operational challenges:

• A visual merchandising compliance app that store managers used to document and track planogram adherence, complete with photo evidence and automated scoring
• An employee scheduling optimization tool that factored in foot traffic forecasts, transaction volumes, and ship-from-store workloads to recommend optimal staffing levels for each shift
• A returns analysis dashboard that identified products with abnormally high return rates and automatically notified the buying team for review
• A new hire onboarding tracker that ensured all training tasks were completed before new employees started working independently
• A store maintenance request system that digitized the process of reporting and tracking facilities issues like lighting failures, HVAC problems, and shelf damage

The citizen developer initiative paid for itself within three months. The employee scheduling app alone saved an estimated 12,000 hours of manual scheduling labor annually across the 127 stores. "Our store managers know what they need better than anyone," said the head of digital transformation. "Before low-code, their only option was to submit a request to IT and wait months — or just keep using Excel. Now they can build the solution themselves in a few days. The speed and creativity that unlocked has been extraordinary."

The citizen developers were supported by a governance framework that included automated security scanning, data access controls, and a peer review process. Applications that handled customer payment data or personally identifiable information required additional security review, but most productivity applications passed through with automated checks. Summit estimated that the citizen developer program delivered approximately $1.2 million in value during its first year, at a program cost of roughly $180,000.

Lessons for Retailers: Making Unified Commerce a Reality

Summit's journey offers several valuable lessons for retail organizations pursuing omnichannel transformation.

Start With Inventory Visibility

Every retailer considering unifying its operations should start with inventory synchronization. Accurate, real-time inventory data is the foundation upon which all other omnichannel capabilities depend. You cannot offer BOPIS, ship-from-store, or endless aisle without knowing what you have and where it is. Summit's inventory module delivered measurable value within weeks of deployment and created the credibility that enabled the broader transformation.

Empower Store Associates With the Right Tools

The success of Summit's unified operations platform depended heavily on adoption by store associates. The team invested significant effort in designing the mobile application for the store floor — making it intuitive, fast, and genuinely helpful to associates in their daily work. Features like barcode scanning for faster picks, visual product images for accurate identification, and one-tap status updates reduced friction and drove adoption. When store associates find the technology useful for their own work, they adopt it enthusiastically, and the omnichannel benefits follow naturally.

Think in Terms of Journeys, Not Channels

The most important mindset shift for Summit was moving from a channel-centric view of the business to a journey-centric view. Instead of asking "how do we optimize our e-commerce channel?" or "how do we improve our stores?", the team asked "how do we optimize the customer's journey across all touchpoints?" This shift revealed opportunities that channel-specific thinking had obscured — such as the value of enabling online customers to return products in-store, or the potential of using in-store inventory data to improve the online shopping experience. The low-code platform's flexibility allowed the team to rapidly prototype and deploy solutions for each journey pain point, iterating based on real customer feedback.

Conclusion: The Unified Commerce Imperative

Summit Home & Living's transformation demonstrates that unified commerce is achievable for mid-sized retail chains without massive IT investments or multi-year implementation timelines. By building an integration and workflow layer on a low-code platform, Summit connected its fragmented systems, created a seamless customer experience across channels, and delivered a 35% increase in omnichannel revenue — all in less than a year and at a fraction of the cost of a traditional platform replacement.

The broader lesson for the retail industry is that the barriers to omnichannel success are no longer technological. Low-code platforms have democratized the ability to build the integration layers, workflow automations, and customer-facing applications that unified commerce requires. The barriers that remain are organizational — breaking down silos between e-commerce and store operations, investing in change management, and committing to a customer-journey-centric view of the business. Retailers that overcome these organizational barriers will find that the technology is waiting to support them.

As Summit's CEO summarized, "We spent years thinking we needed a massive system replacement to compete with the big players. What we actually needed was the courage to build what we needed, one piece at a time, with the right platform and the right team. Project Unified proved that a regional retailer can innovate faster than the giants — if you're willing to rethink not just your technology, but your entire approach to building technology."
