3PL & Contract Warehousing Operations

Multi-client warehouse management for manufacturers and distributors with storage billing, dock scheduling, and trading partner connectivity.

Contract warehouse operators supporting manufacturers and distributors manage multiple clients, changing volumes, and tight SLAs under the same roof. Inventory Pro keeps each client's stock isolated and auditable while giving your operations team one execution view from inbound appointments through pick, pack, ship, and storage billing.

Multi-Client Inventory Management

Keeping client inventories separate, visible to the right people, and accurately billable is the foundation of distribution center operations. Inventory Pro handles this at the architecture level.

Warehouse-Level Isolation

Each client's inventory is managed within its own warehouse context with independent access controls. Your operators can work across all accounts from a single interface, while role-based security ensures clients only see their own data - inventory levels, orders, history, and reports all respect warehouse boundaries.

Customer Access Portal

Grant your clients limited access to review their inventory levels, order status, and transaction history. Fine-grained permission controls let you decide exactly what each client can view and do within the system - without exposing your operational data or other clients' information.

Inbound Operations

Receiving starts before the truck backs in. Inventory Pro provides the scheduling and receiving tools that keep docks organized and counts accurate from the moment material enters the building.

Dock Scheduling

Schedule inbound appointments with carrier and vendor associations, datetime windows, and status tracking. Coordinate dock capacity across multiple clients to prevent congestion and delays.

Receiving and Putaway

Receive against purchase orders or blind-receive with barcode scanning. Automatic lot number assignment, serial tracking, and expiration date capture at the point of receipt. Mobile putaway directs stock to the correct location.

ASN and EDI

Accept inbound EDI X12 transactions (850 Purchase Orders, 940 Warehouse Shipping Orders) via AS2, FTP, or file sharing. Advance Shipment Notices enable pre-receiving workflows that reduce dock time.

Outbound Operations

Getting the right product to the right destination on time is the core promise of distribution. Inventory Pro handles the full outbound workflow from order receipt through carrier handoff.

Storage Fees and Client Billing

3PL revenue depends on accurate, defensible billing. Inventory Pro tracks the data you need to bill clients for space and services consumed.

Storage Fee Tracking

Track time on the floor for inventory by client, location, and item. Storage fee calculations give you the data foundation for client billing based on actual warehouse utilization - whether you bill by pallet position, cubic footage, or time-based storage.

Leasing and Asset Management

The leasing module tracks assets and equipment assigned to specific clients with return management and FIFO selection. For 3PLs that provide equipment along with warehouse space, this adds another billable dimension to client relationships.

Inventory Accuracy and Visibility

Clients trust you with their stock. That trust depends on accuracy and transparency.

Cycle Count Programs

Multiple sampling methods for ongoing inventory accuracy, with approval workflows and digital signature verification for audit-grade counts.

Lot and Serial Traceability

Full lot number, serial number, and expiration date tracking from receipt through shipment - critical for clients in regulated industries.

Barcode and RFID Scanning

1D, 2D, QR, and RFID support on desktop and mobile. Works with standard commercial hardware - no proprietary devices required.

Transit Slips

Track inter-warehouse transfers with origin/destination warehouse identification, line-item detail, and approval tracking for cross-dock and multi-facility operations.

Warehouse Floor Maps

Virtual floor maps support picking optimization and help new warehouse staff navigate the facility efficiently.

Detailed Reporting

Pre-built reporting across inventory, orders, and operations. Custom reports available for client-specific SLA metrics and performance dashboards.

Trading Partner Connectivity

Distribution operations sit at the intersection of multiple supply chains. Inventory Pro connects to your clients' systems and trading partners through multiple channels.

EDI and Data Exchange

  • EDI X12 transactions (850, 940) via AS2, FTP, file sharing
  • XML and cXML integrations for supply chain data exchange
  • UPS WorldShip for shipment generation and tracking
  • Import/export framework for Excel, CSV, and flat files

API and Custom Integration

  • REST API for real-time system integration
  • Inventory, shipping, warehouse, and work order endpoints
  • Accounting integrations (Sage 50, QuickBooks, Spectrum)
  • Custom one-off integrations available via development services

Deployment and Scalability

Whether you run a single DC or a network of fulfillment centers, Inventory Pro scales with your operation. Cloud hosting on Microsoft Azure provides managed infrastructure with dedicated instances, while on-premises deployment is available for teams that manage their own infrastructure. Concurrent user licensing means you pay for active sessions, not named seats — cost-effective for shift-based warehouse operations where staff rotate throughout the day.
