10 Common Problems With Order Picking… and How to Solve Them
Key takeaways
- Most picking problems stem from slow data, unclear workflows, or lack of real-time visibility.
- Simple workflow improvements can remove bottlenecks without adding labour.
- Fast-growing ecommerce teams solve accuracy issues with mobile scanning and guided pick paths.
Order picking should be simple, but rapid ecommerce growth makes even small errors expensive. Missed items, slow routes, and manual processes add friction you feel immediately. And over time, these issues ultimately lead to longer fulfilment times, unhappy customers, and exhausted teams.
This guide breaks down the most common problems with order picking and shows practical fixes so you can scale without adding headcount.
Top 10 problems with order picking
- Wrong item location in warehouse
- Mispicks; human error
- Paper-based picking
- No priority when picking
- Labour-intensive picking
- No designated location for half-picked orders
- Fixed locations in warehouse
- Relying on human memory
- One order per pick run
- No picker accountability
This article covers the solutions to these problems and also answers the common question: how to reduce manual picking errors.
Problem 1: Wrong item location in warehouse
This occurs when a picker goes to the warehouse location to pick an order, and the correct item is not there.
Impact
If an item is not where it should be in the warehouse, this means the picker needs to spend time looking for it. This delays the order fulfilment, which can lead to an unhappy customer and negative reviews. On top of that, it also makes for a highly inefficient warehouse operation.
How to solve it
With a warehouse management system (WMS), every item is scanned into a location. This means that when a picker is looking for an item, it will always be exactly where it should be.
Problem 2: Mispicks; human error
A mispick is when a picker makes a mistake, which means the wrong items or quantities are picked.
Impact
If the wrong items or quantities are picked, time is wasted at the pack bench where, hopefully, the error is noticed. As well as costing money, it also paints a poor picture of your brand.
How to solve it
Get goods-in right first time by scanning everything. Using barcode scanners in your ecommerce warehouse should make it impossible to pick the wrong item or the wrong quantity.
Problem 3: Paper-based picking
You are printing orders on sheets of paper and sending the pickers to manually check off their pick lists.
Impact
This kind of operation is not only a lengthy process, but it is also highly inefficient and leaves a large margin for error due to lost or unfulfilled orders.
How to solve it
Quite simply: eliminate paper from your warehouse by using warehouse management software with a mobile app.
Problem 4: No priority when picking
All of the orders are lumped together, and there is no process for deciding which orders should be picked first.
Impact
If your orders are not prioritised, then often the most recent sales order items are picked first by default.
How to solve it
To solve this problem, you should find a suitable method for sorting your warehouse orders.
Problem 5: Labour-intensive picking
Your picking process heavily relies on human effort and expertise.
Impact
If you have too many pickers working at the same time, you will likely be spending more money on labour than you are getting back in return.
How to solve it
The most efficient way to reduce the number of pickers needed for a single shift is to introduce automation into your warehouse.
| Without structured picking workflows | With structured, guided workflows |
|---|---|
| Pickers walk too much and waste time between locations. | Routes are optimised automatically so staff move through the warehouse with fewer steps. |
| Frequent errors lead to repicks, returns, and extra customer service work. | Scanning confirms each pick and pack, so accuracy improves and mistakes drop. |
| New hires take a long time to learn locations and processes. | Guided mobile workflows show the next task on-screen, which speeds up onboarding. |
| Hard to scale order volume without adding more people to the team. | Higher throughput per picker means you can handle more orders with your existing staff. |
Problem 6: No designated location for half-picked orders
Orders that are only half-picked are generally put back if the remaining items are not available.
Impact
Dispatched half-orders increases your overall shipping costs.
How to solve it
The ultimate solution is to manage your allocation properly which means orders are only half-picked if you’re happy to do a partial shipment.
Problem 7: Fixed locations in warehouse
Impact
Having fixed locations eliminates the potential for flexibility to allocate high-demand items closer to the pack bench when necessary.
How to solve it
Introduce a WMS that allows for dynamic locations.
Problem 8: Relying on human memory
Impact
Time is required to train pickers on the layout of the warehouse.
How to solve it
With a WMS, the location of every SKU should be recorded.
Problem 9: One order per pick run
Impact
This is an inefficient process that wastes valuable time and resources.
How to solve it
By eliminating paper and using WMS workflows instead, pick runs can be devised in the most efficient manner.
Problem 10: no picker accountability
Impact
No accountability in a team is divisive, demotivating, and hard to manage.
How to solve it
A suitable WMS should provide you full visibility on all inventory movements, including which member of staff has performed each action.
Order picking FAQs
What are the biggest order picking problems?
Common issues include wrong item locations, mispicks, paper-based picking, no clear order priorities, labour-intensive processes, no space for half-picked orders, fixed locations, reliance on memory, picking one order per run, and no picker accountability.
How can warehouses reduce order picking errors?
A key step is replacing paper and memory with warehouse management software.
Why is picker accountability so important?
Without accountability, managers struggle to see who picked an order, where mistakes occur or how efficiently staff are working.
How can I measure order picking performance in my warehouse?
Start by tracking key metrics such as picks per hour, order accuracy rate, average travel time per pick, and cost per order fulfilled.
When is it time to upgrade your order picking process?
If order volume is increasing but fulfilment speed and accuracy are declining, your current process may not be sustainable.
