The order fulfillment process is where your warehouse delivers value to customers. Every step, from receiving the order to handing the package to a carrier, must be executed accurately and efficiently. SmartWMS provides a structured workflow that guides your team through each stage while maintaining full traceability and minimizing errors.
The Complete Order Lifecycle
In SmartWMS, every order passes through a defined set of stages. Understanding this lifecycle is essential for optimizing your throughput and identifying bottlenecks:
- Order Import – Orders enter the system via manual entry, CSV upload, or API integration
- Validation – SmartWMS checks inventory availability and flags issues
- Wave Planning – Orders are grouped into waves for efficient processing
- Pick Assignment – Pick tasks are generated and assigned to operators
- Picking – Operators collect items from storage locations
- Packing – Items are verified, packed, and labeled
- Shipping – Carrier labels are generated and packages are dispatched
Inbound: Receiving and Put-Away
Before you can fulfill outbound orders, you need to receive inventory into the warehouse. The inbound process in SmartWMS follows two key steps:
Receiving
When a shipment arrives at your dock, create or open the corresponding purchase order in SmartWMS. Operators scan each item as it comes off the truck, and the system compares the received quantities against the expected quantities. Any discrepancies, such as short shipments, overages, or damaged goods, are flagged immediately.
For suppliers that use GS1-128 barcodes, SmartWMS can automatically extract lot numbers, expiration dates, and serial numbers from the scan, eliminating manual data entry entirely.
Put-Away
Once items are received, SmartWMS generates put-away tasks that direct operators to the optimal storage location. The system considers factors such as:
- Product velocity (fast movers go to easily accessible locations)
- Product dimensions and weight (heavy items stay at floor level)
- Zone restrictions (hazardous materials go to designated areas)
- Available bin capacity
Operators follow the on-screen directions, scan the destination bin to confirm placement, and the inventory record is updated in real time.
Outbound: Pick, Pack, and Ship
Wave Planning and Order Grouping
Processing orders one at a time is inefficient. SmartWMS allows you to group orders into waves based on criteria such as carrier, shipping priority, destination region, or product type. Wave planning consolidates pick tasks so that an operator can fulfill multiple orders in a single trip through the warehouse.
For example, if you have 30 orders that all need items from the same zone, SmartWMS creates a batch pick list that routes the operator through that zone once, rather than sending them back and forth 30 times.
Pick Strategies
SmartWMS supports several picking strategies to match different operational needs:
- Discrete Picking – One operator picks one order at a time, start to finish. Simple and easy to train, best for low-volume operations.
- Batch Picking – One operator picks items for multiple orders simultaneously, sorting them during or after the pick. Ideal for operations with many small orders.
- Zone Picking – Each operator is assigned to a specific zone and picks only the items in that zone. Orders with items in multiple zones are consolidated downstream.
- Wave Picking – A combination of batch and zone picking, where orders are grouped into waves and distributed across zones and operators.
The system generates optimized pick paths that minimize travel distance within each strategy. Operators see clear instructions on their screen or mobile device: which item to pick, which location to go to, and how many units to collect.
Pick Verification
At each pick location, operators scan the location barcode and the product barcode to confirm they are picking the correct item from the correct place. This double-verification process catches errors before they reach the customer. If an operator scans the wrong item or location, SmartWMS displays an immediate warning.
Packing and Quality Control
After picking, items move to the packing station. Here, operators verify the contents of each order against the packing slip. SmartWMS displays the expected items and quantities, and the operator scans each item as it goes into the box.
The packing station workflow also handles:
- Box size selection and cartonization recommendations
- Insertion of promotional materials or documentation
- Weight verification to catch missing items
- Photo capture for high-value orders (optional)
Shipping and Carrier Integration
SmartWMS integrates with major shipping carriers and label APIs. Once an order is packed, the system can automatically:
- Select the optimal carrier based on cost, speed, and destination
- Generate shipping labels and tracking numbers
- Update the order status and notify the customer
- Create customs documentation for international shipments
Shipping labels are printed directly at the packing station, and the tracking number is synced back to the source system (e-commerce platform, ERP, or marketplace).
Handling Exceptions
Not every order flows smoothly. SmartWMS provides structured exception handling for common scenarios:
- Short Picks – When the system directs an operator to a location with insufficient stock, they can report a short pick, which triggers a recount and reallocates the order to an alternate location if available.
- Backorders – Items that are out of stock can be placed on backorder status, with automatic fulfillment when new stock is received.
- Returns – Returned items enter a separate receiving workflow where they are inspected, graded, and either restocked or disposed of.
- Cancellations – Orders can be cancelled at any stage before shipping, with automatic inventory release.
Measuring Fulfillment Performance
SmartWMS tracks key metrics throughout the order lifecycle:
- Order Cycle Time – Time from order receipt to shipment
- Pick Accuracy – Percentage of picks completed without errors
- Lines Per Hour – Operator productivity measurement
- On-Time Shipment Rate – Percentage of orders shipped by the promised date
- Perfect Order Rate – Percentage of orders delivered complete, on time, damage-free, and with correct documentation
The goal of any fulfillment operation is not just speed but consistency. SmartWMS provides the structure and visibility you need to deliver the right product, to the right customer, at the right time, every time.
