According to the National Retail Federation, inventory shrinkage alone costs U.S. retailers $61.7 billion annually, with administrative errors and supplier fraud accounting for 26.8% of those losses. When your team manually tracks 10,000+ SKUs across multiple warehouses using Excel spreadsheets or disconnected legacy systems, every minute spent reconciling counts is money lost to inefficiency.
We worked with a West Michigan automotive parts distributor managing 47,000 SKUs across three warehouses. Their legacy AS/400 system required 16 hours weekly just to generate accurate inventory reports. When their purchasing manager placed orders, the data was already 3-4 days old, leading to $127,000 in emergency freight charges annually for rush orders on parts they thought were in stock.
The problem intensifies when your inventory system doesn't communicate with your ERP, accounting software, or e-commerce platform. A Kalamazoo-based industrial equipment supplier we partnered with was manually entering sales orders from their website into QuickBooks, then separately updating inventory counts in a custom Access database. Order processing took 18 minutes per transaction, and their inventory accuracy hovered around 73%—well below the 95%+ industry standard.
Barcode scanning alone doesn't solve the core issue if your underlying database architecture can't handle complex inventory rules. We've seen manufacturers attempt to implement basic barcode systems only to discover they can't track lot numbers, expiration dates, serial numbers, and bin locations simultaneously. When a food distributor in Grand Rapids needed to recall a specific production lot, they spent 11 hours manually searching through paper records because their system couldn't filter by manufacture date.
Multi-location inventory creates exponential complexity. When you're managing stock across warehouses, retail locations, consignment inventory, and third-party logistics providers, you need real-time visibility into every unit. A furniture retailer we worked with lost $89,000 in a single quarter by shipping inventory between locations that was already available—they just couldn't see it in their fragmented system.
The financial impact extends beyond the obvious carrying costs. When you can't accurately forecast demand because your historical data is incomplete or unreliable, you either overstock (tying up capital and warehouse space) or understock (losing sales and frustrating customers). According to research from the Harvard Business Review, companies with poor inventory visibility typically carry 20-30% excess safety stock as a buffer against uncertainty.
Integration failures compound these problems. Your inventory system should automatically trigger purchase orders when stock hits reorder points, update your accounting system when you receive goods, adjust quantities when sales occur, and sync with your shipping software for fulfillment. When a logistics company approached us, they had seven different software systems that required manual data entry between each one. Their team spent 32 hours weekly just moving data between systems—time that should have been spent on strategic planning.
The opportunity cost is substantial. While your warehouse manager spends 15 hours conducting monthly physical counts, your purchasing team is placing orders based on gut feeling rather than data-driven reorder points, and your sales team is promising delivery dates they can't guarantee, your competitors with modern inventory systems are operating with 99% accuracy, turning inventory 2-3 times faster, and reducing carrying costs by 25-40%.
Manual inventory counts taking 15-20 hours monthly with accuracy rates below 80%, requiring constant cycle counting and reconciliation
Stock discrepancies between physical inventory and system records causing order fulfillment errors that damage customer relationships
No real-time visibility across multiple warehouse locations, leading to unnecessary transfers and duplicate emergency orders
Inability to track lot numbers, serial numbers, expiration dates, or other critical product attributes required for compliance
Disconnected systems requiring manual data entry between inventory, accounting, e-commerce, and shipping platforms
Reorder points based on guesswork rather than actual demand patterns, resulting in chronic overstocking or stockouts
Emergency freight charges averaging $8,000-$15,000 monthly due to poor inventory planning and rush orders
No mobile access for warehouse staff, forcing them to write counts on paper then manually enter data later
Our engineers have built this exact solution for other businesses. Let's discuss your requirements.
We design and build custom inventory management solutions that address your specific operational requirements, whether you're tracking 500 SKUs or 500,000. Unlike off-the-shelf software that forces you to adapt your processes to fit their limitations, our systems are architected around how your business actually operates—from receiving and putaway to picking, packing, and shipping.
Our [custom software development](/services/custom-software-development) approach starts with your database architecture. We build normalized SQL databases optimized for inventory transactions, typically using Microsoft SQL Server or PostgreSQL depending on your infrastructure. For a Holland-based food distributor, we designed a database schema handling 12,000 products with lot tracking, FIFO costing, catch-weight items, and automatic USDA compliance reporting. Their inventory queries that previously took 45-60 seconds now return results in under 2 seconds.
Real-time inventory accuracy comes from intelligent barcode scanning workflows integrated directly into your warehouse operations. We've implemented systems using Zebra mobile computers, Honeywell ring scanners, and fixed-position RFID readers depending on the use case. Our [Real-Time Fleet Management Platform](/case-studies/great-lakes-fleet) demonstrates our capability to handle real-time data synchronization—the same architecture principles apply to inventory systems where every scan immediately updates centralized databases.
Integration with your existing business systems is foundational to our approach. We specialize in [systems integration](/services/systems-integration) that creates bidirectional data flow between your inventory system and platforms like QuickBooks, Sage, NetSuite, Salesforce, Shopify, WooCommerce, and ShipStation. Our [QuickBooks Bi-Directional Sync](/case-studies/lakeshore-quickbooks) case study shows how we handle complex accounting integrations—we apply those same techniques to ensure inventory adjustments automatically update your general ledger and cost of goods sold.
Automated reordering functionality uses your actual demand patterns, lead times, and service level requirements to calculate optimal reorder points and quantities. We implement economic order quantity (EOQ) calculations, ABC analysis for inventory classification, and safety stock formulas that account for demand variability and lead time uncertainty. A Grand Rapids HVAC distributor using our system reduced their inventory carrying costs by 34% while simultaneously improving in-stock rates from 87% to 98%.
Mobile-first interfaces give your warehouse team the tools they need without being chained to desktop workstations. We build responsive web applications that work on any device, plus native iOS and Android apps when offline functionality is critical. Warehouse staff can receive inventory, conduct cycle counts, pick orders, and adjust stock levels from anywhere in your facility. A Battle Creek manufacturer we worked with reduced their receiving time per shipment from 28 minutes to 9 minutes by eliminating the walk back to the computer after each pallet count.
Advanced reporting and analytics transform your inventory data into actionable business intelligence. We create custom dashboards showing inventory turnover by category, aging reports highlighting slow-moving stock, ABC analysis identifying your most valuable items, and demand forecasting based on historical patterns. Our [SQL consulting](/services/sql-consulting) expertise ensures these reports execute quickly even with millions of transaction records.
The systems we build scale with your business. Whether you're adding new warehouse locations, expanding product lines, or increasing transaction volumes, the architecture supports growth without performance degradation. We've built inventory systems handling 50 transactions daily and others processing 5,000+ daily transactions across dozens of concurrent users.

Demand forecasting using historical sales patterns, seasonal trends, and promotional lift. ABC analysis categorizing inventory by revenue contribution. Supplier performance scorecards tracking lead time accuracy and quality issues.
The custom inventory system FreedomDev built reduced our monthly physical inventory from 22 hours to 3 hours, and our accuracy went from 79% to 99.1%. More importantly, we cut our inventory carrying costs by $186,000 in the first year by finally having accurate data to make purchasing decisions.
We spend 1-2 weeks analyzing your existing inventory processes, conducting warehouse walkthroughs, and interviewing staff from receiving through shipping. We document your current software systems, integration points, transaction volumes, and specific pain points. This assessment produces a detailed requirements document covering product attributes, workflow requirements, integration needs, reporting needs, and success metrics.
Our development team architects the database schema and system infrastructure to support your specific requirements. We design table structures for products, locations, transactions, and costs, optimizing indexes for query performance. For companies with existing data, we create migration scripts that preserve historical transactions while cleaning up data quality issues. We define API architectures for integrations and establish security models for role-based access control.
We build the foundational inventory modules—receiving, putaway, picking, adjustments, transfers, and cycle counting—using iterative development with bi-weekly demos. Simultaneously, we develop integrations with your accounting system, e-commerce platform, and shipping software using their APIs or database connections. Each integration includes error handling, logging, and automated reconciliation to catch sync issues immediately.
Based on your warehouse environment and budget, we recommend appropriate barcode scanners, mobile computers, label printers, and RFID equipment. We develop mobile scanning applications optimized for warehouse workflows, including large touch targets, minimal data entry, and offline capability where needed. We conduct on-site testing in your actual warehouse to refine the user interface based on real-world usage patterns.
We conduct role-specific training sessions for warehouse staff, purchasing teams, and management, typically 2-4 hours per group. We implement a parallel testing period where your team uses both the old and new systems simultaneously, allowing us to validate data accuracy and identify any edge cases requiring adjustment. We refine workflows based on user feedback and document standard operating procedures for ongoing reference.
During your first two weeks of live operation, we provide on-site or immediate remote support to address any issues as they arise. We monitor system performance, integration success rates, and user adoption metrics daily. After stabilization, we transition to ongoing support and enhancement, implementing new features based on your evolving needs and optimizing performance as transaction volumes grow.
