Picking is one of the most labour-intensive and error-prone activities inside a warehouse. When picking slows down or goes wrong, the impact isn’t limited to a single aisle or order; it cascades across dispatch timelines, inventory accuracy, and overall fulfillment efficiency.
Why, Where, and When Picking Accuracy Matters?
- A single picking error can cost up to $22 once rework, returns, and reshipment are factored in.
- In retail, just 2–3 incorrect orders are enough for 81% of buyers to stop purchasing.
- In quick commerce, B2B suppliers often handle 30–40 replenishment POs a day, each with 800–1,000 units—so even one wrong pick can disrupt multiple dark stores at once.
Whether it’s retail, B2B fulfillment, or quick commerce operations, the requirement is the same: fast, accurate, and controlled picking at scale.
In this blog, we’ve covered the core picking challenges, the business impact of wrong picks, and how handheld-led picking with Unicommerce’s new app- Unicommerce scale helps brands increase their picking efficiency and warehouse productivity.
How Warehouse Picking Works for Most Brands Today
1. Paper Picklists: Nearly 1/2 of warehouses still rely on paper-based or spreadsheet picking methods. Let’s go through a scenario.
A picklist printed at 9 a.m. is already outdated by noon. Stock shifts, priority orders arrive, and allocations change, but the paper doesn’t. Pickers adapt on the fly, replacing system logic with assumptions.
Example: A rush order is added after picklists are printed. The picker fulfills it using nearby stock, causing a silent shortfall in another order.
2. Desktop-Based WMS: System awareness comes too late
When the WMS lives on a desk, not on the floor, picks happen without validation. The system only catches errors after the damage is done, during packing, audits, or customer complaints.
Example: A picker selects a visually similar SKU. The mismatch is detected only at packing, forcing re-picking and delaying dispatch.
3. Memory-Driven Picking: Experience replaces enforcement
In warehouses with look-alike SKUs, variants, or batch constraints, reliance on memory and visual cues increases error probability—especially during peak volumes or staff rotation.
Example: Two sizes of the same product share a location. A picker grabs the wrong variant, leading to returns and inventory distortion.
When picking runs on fragmented processes, errors multiply, rework increases, and fulfillment reliability weakens, eventually eroding revenue. While B2C and B2B operations face different execution realities, fragmented picking introduces risk across both. Let’s break down the picking challenges in B2C and B2B environments.
What Are the Picking Challenges in B2C Warehouses?
B2C picking runs on speed. Orders arrive continuously, SKUs move frequently, and dispatch cut-offs leave no margin for error.
Reality on the floor:
A picker is responsible for multiple orders simultaneously. When fast-selling items change locations during the day, the absence of real-time guidance forces the picker to rely on guesswork or manual checks reducing picking speed across the warehouse.
What breaks:
- Time lost locating SKUs
- Look-alike variants picked incorrectly
- Errors discovered only at packing
- Delays during peak sales and festive hours
Picking Challenges in B2B Warehouses
B2B picking runs on accuracy. Orders are larger, quantities are higher, and mistakes are costly.
On the floor:
A bulk order requires multiple cartons of the same SKU. Quantities are counted manually. The system validates only after dispatch.
What breaks
- Over- or under-picked quantities
- Manual reconciliation at dispatch
- Slower picking to avoid mistakes
- Scaling requires more manpower, not better execution
How Does Inefficient Picking Impact the Overall Operational Metrics?
This is a common challenge for warehouse managers, where inefficiencies in picking quickly translate into measurable operational setbacks.
1. Increase in SLA breaches: Across marketplaces and quick-commerce platforms, even minor delays in picking can cause missed dispatch cut-offs, leading to SLA breaches and resulting penalties for sellers.
2. Deal With Re-shipment and Increased Returns: Incorrect picks force brands to manage avoidable returns and re-shipments, adding unnecessary workload for warehouse teams and increasing operational costs.
3. Longer order processing: During sales and festive peaks, even small picking delays compound quickly, slowing overall throughput and putting high-volume order fulfillment at risk.
This list can go on, but these challenges aren’t unavoidable. They can be addressed by transforming traditional warehouses into a fully system-led picking operation.
Turning Warehouse Picking into a System-Led Process
Here is a quick overview of how you can improve your order picking process.
| Traditional Picking Methods | Device-Led Picking |
| Printed Excel sheets | Mobile-first workflows |
| Manual SKU and quantity checks | System-guided picking instructions |
| Updates entered after picking | Real-time system updates |
| Relies on memory and experience | Barcode-led verification |
| Errors found at packing or audit | Errors prevented at pick time |
| Shipment delays during peak periods | Faster, on-time dispatch |
| Hard to scale without adding manpower | Scales without adding complexity |
This shift demands more than incremental process changes. It requires a system that brings real-time intelligence directly to the warehouse floor, where every pick is guided, validated, and updated instantly.
This is where Unicommerce’s app-enabled, handheld and mobile-led warehouse execution comes into play.
