RFID tags allow passive tracking without line-of-sight scanning, enabling bulk inventory counts and automated monitoring of high-value components. Some systems combine both technologies, using barcodes for individual transactions and RFID for periodic inventory verification.

Bin location management assigns specific storage locations to each part, guiding personnel to the correct shelf, bin, or drawer. Location systems may use alphanumeric codes, LED indicators, or pick-to-light technology that illuminates the correct storage location. Optimized location assignment considers part velocity, size, weight, and picking frequency to minimize retrieval time.

Stock level monitoring continuously tracks quantities against minimum and maximum thresholds. When inventory falls below reorder points, systems generate alerts or automatic purchase orders. Sophisticated algorithms consider lead times, seasonal demand variations, and safety stock requirements to determine optimal reorder quantities. Multi-location operations require visibility across all sites to enable transfers and balanced inventory distribution.

Lot and serial number tracking provides traceability for parts requiring specific identification. This capability is essential for warranty claims, recall campaigns, and quality control. Serial number tracking is particularly important for high-value components such as electronic control modules, transmissions, and engines where individual unit history affects warranty coverage and core return value.

Consignment inventory management handles parts owned by suppliers but stored at service facilities. These systems track consignment stock separately from owned inventory, generating usage reports for supplier billing while maintaining accurate total availability counts. Consignment arrangements can improve cash flow by deferring payment until parts are actually used.

Procurement and Ordering Systems

Electronic procurement systems streamline the ordering process, connecting service facilities with suppliers through integrated ordering platforms that reduce manual effort and improve accuracy.

Electronic data interchange (EDI) enables automated communication with suppliers using standardized message formats. Purchase orders, order acknowledgments, advance shipping notices, and invoices flow electronically between systems without manual data entry.
