Stock accuracy low because your systems don't update in real time?
Stockouts and overstocking happening simultaneously across different SKUs?
Inventory Management Software Development
Spreadsheet inventory management breaks down when your SKU count grows, your locations multiply, or your fulfilment speed requirements exceed what manual tracking can support. You end up with stock accuracy problems, stockouts, and overstocking -- all at the same time.
We build custom inventory management systems designed for your specific product types, warehouse layout, and fulfilment operations. Real-time stock visibility, reorder automation, and the integrations your operations stack requires.
Custom inventory tracking for your product types, locations, and fulfilment model
Real-time stock levels, movement history, and reorder automation
Barcode, QR code, and RFID support for physical stock management
Integration with your ERP, e-commerce, WMS, and supplier systems
RaftLabs builds custom inventory management software — real-time stock tracking, automated reorder triggers, barcode and RFID scanning, multi-location inventory, and ERP integration — for businesses whose operations are too specific for generic inventory platforms. Every system is built around your product lines, warehouse layout, and supplier relationships, not a generic template. Fixed cost with full IP ownership.
Inventory accuracy is not a process problem. It's a systems problem.
When stock levels live in spreadsheets or disconnected systems, the data is always behind reality. Items are sold that aren't in stock. Items sit in the warehouse that nobody knows are there. Reorders happen too late or too early because nobody has a reliable number.
Custom inventory management software gives you one source of truth -- updated in real time as stock moves, connected to the systems that create stock movements, and visible to everyone who needs it.
What we build
Real-time stock tracking
Stock levels updated the moment goods are received, picked, transferred, or written off. Movement history for every SKU -- when it arrived, where it went, what it cost. Current stock across all locations in one view. No end-of-day batch updates, no manual counts to reconcile against a spreadsheet.
Receiving and goods-in
Purchase order-based receiving with discrepancy reporting. Barcode or RFID scanning for fast, accurate goods-in. Lot number, serial number, and expiry date capture at receipt. Quality check steps before stock is available. Supplier performance tracking by delivery accuracy and lead time.
Reorder and replenishment
Reorder point triggers based on stock level and lead time. Automated purchase requisition generation when stock falls below threshold. Safety stock calculation based on demand variability. Supplier lead time tracking for accurate reorder timing. The reorder system that prevents stockouts without creating overstock.
Lot and serial tracking
Lot/batch tracking with full traceability from receipt to sale. Serial number assignment and tracking for individual items. FEFO picking enforcement for products with expiry dates. Lot-level recall management -- trace every unit from a specific batch within minutes. The compliance-grade tracking that food, pharma, and medical device businesses need.
Mobile scanning
Mobile app for warehouse staff to scan stock movements from a phone or tablet. Receive POs, pick orders, conduct cycle counts, and perform stock transfers -- all from a mobile device. Works on iOS and Android. Offline mode for warehouses with patchy connectivity. The same data accuracy without the fixed terminal.
Reporting and analytics
Stock valuation reports by location, product category, and date. Inventory turnover, days on hand, and slow-mover reports. Cycle count variance reports. Shrinkage and write-off analysis. Supplier fill rate reporting. The inventory intelligence your purchasing and operations teams need to reduce carrying costs and improve availability.

Frequently asked questions
Custom inventory management software is a system built around your specific product catalogue, warehouse layout, and stock management workflows -- rather than a generic platform you adapt to fit your operations. A custom system tracks stock in real time as it moves, enforces the business rules specific to your products (lot tracking, expiry dates, serial numbers, FIFO/FEFO), and integrates with your existing systems for automated stock updates across channels.
Custom makes sense when: (1) Your product types have specific tracking requirements that generic platforms handle poorly -- lot numbers, serial numbers, expiry dates, custom attributes. (2) You operate across multiple locations, warehouses, or fulfilment centres and need unified visibility. (3) Your inventory data needs to flow automatically between your e-commerce platform, ERP, and 3PL -- and the native integrations between them are insufficient. (4) You're doing something non-standard -- consignment inventory, customer-owned stock, complex FEFO rules. Off-the-shelf platforms like TradeGecko or Cin7 are good for standard retail inventory. Custom makes sense when your operations are the differentiator.
We build inventory systems for physical products with standard SKU tracking, lot/batch-tracked products (food, pharma, chemicals), serialised products (electronics, machinery, medical devices), and products with expiry dates requiring FEFO management. For physical tracking, we support barcode scanning (1D and 2D), QR codes, and RFID. We build mobile apps for warehouse staff to scan stock movements from a phone or tablet. The tracking method is designed around your product characteristics and warehouse operations.
Multi-location inventory means you need to see stock across all your locations at once -- not in separate systems. We build systems with a unified stock view across warehouses, retail locations, 3PL facilities, and in-transit stock. Stock transfers between locations are tracked with full movement history. Each location can have its own reorder points, minimum stock levels, and receiving workflows. The unified view gives you the data to make replenishment decisions across the whole network.
Common integrations for inventory management systems include e-commerce platforms (Shopify, WooCommerce, Magento) for order-driven stock deductions, ERP systems (SAP, NetSuite, Dynamics) for financial stock valuation, warehouse management systems for pick-pack-ship operations, supplier systems for purchase order management and ASN receipt, and shipping carriers for fulfilment tracking. We scope the integration requirements during discovery and build the connectors specific to your stack.
A focused inventory management system -- single or multi-location stock tracking, reorder management, and basic integrations -- typically runs $30,000--$70,000. Multi-warehouse platforms with advanced lot tracking, mobile scanning apps, and multiple system integrations run $70,000--$150,000. Cost depends on the complexity of your product catalogue, the number of locations, and the integrations required. We scope every project before pricing it.
