Paper works until it does not. Pick tickets, count sheets and receiving logs all get written on the floor and typed in later, and every retype is a chance for a mistake and a delay. Going mobile means the record is made where the work happens. The device gets most of the attention, but the workflow decides whether the change sticks.
What paper actually costs you
- Double entry. Someone writes it on the floor and someone else types it in the office. Errors creep in at the second step, and nobody can tell which copy is right.
- Lag. Stock on hand in the system is only as current as the last batch of typing. Reps sell product that has already gone out, or miss product that just came in.
- Missing lots and dates. When the clipboard is full and the truck is waiting, the lot number and expiration date are the first things skipped. Without them, lot tracking has gaps, FEFO rotation breaks and a recall is slow.
- No trail. Paper rarely says who did what and when. When a count is off, there is nothing to follow back.
Choosing devices: phones or rugged handhelds
There are two realistic options for putting software in a warehouse worker's hand. Each has a place.
| Question | Consumer phone, camera scanning | Rugged handheld, built-in scanner |
|---|---|---|
| Cost per device | Lower | Higher |
| Scanning all shift | Fine for occasional scans; slower on worn or distant barcodes | Built for constant scanning with a physical trigger |
| Drops, cold and wet | Needs a protective case; cold drains the battery | Designed for it |
| Gloves | Touchscreens can be awkward with gloves | Physical buttons help |
| Learning curve | Almost none; everyone owns one | Short, but real |
Many warehouses mix the two: phones for receiving, counts and supervisors, rugged handhelds for high-volume picking and freezer work. Decide by task, not by budget alone. A picker who scans hundreds of cases a shift in a freezer is a different user from a manager checking a pallet on the dock.
Plan for the cold either way. Batteries drain faster in a freezer, and devices that move between the freezer and a warm dock collect condensation. A spare device and a charging spot near the cold rooms solve most of it.
Installed app or web app?
The software reaches the device in one of two ways. An installed app comes from the App Store, Google Play or your device management tool. A web app, often built as a progressive web app (PWA), opens from a link and can be saved to the home screen. Web apps are easy to roll out. Installed apps usually get fuller access to the camera, hardware scanners and offline storage. The label matters less than the answers to these questions:
- Does it keep working when Wi-Fi drops in the walk-in, and does it send the work once the connection comes back?
- Does it read the built-in scanner on a rugged handheld as well as the camera on a phone?
- How do updates reach every device at once?
- How does a person sign in on a shared device, so each scan is tied to whoever made it?
What the software should cover
- Receiving. Check the delivery against the PO, record the lot and date, note shorts and damage.
- Putaway. Record where each pallet went, so the next person can find it.
- Picking. Show the next pick and the lot to take, and confirm with a scan.
- Counts. Count a section without stopping the building, and show variances to a manager. Our guide to cycle counting without shutting down covers how to schedule them.
A five-step rollout
- Start with one workflow in one area. Receiving or counts are good first choices because mistakes are easy to see. Run the pilot for a couple of weeks before expanding.
- Fix the floor first. Locations need readable labels and items need scannable barcodes. Our article on bin labeling covers the location side. List the items with no barcode and decide how they will be labeled.
- Buy one more device than you need. One will get dropped or left on a charger at the wrong moment.
- Train on the job, with a strong picker first. Your fastest people find the gaps in a workflow quickly, and others learn from them.
- Expand area by area, then retire the paper. Set a date, announce it and keep it. Running paper and devices side by side for long means nobody trusts either record.
What to watch in the first month
- Wi-Fi dead spots. Walk the building with a device before go-live, including coolers, freezers and the far end of the dock.
- Charging. Set a charging spot and a rule for shift change, or devices die mid-pick.
- Exceptions. Decide what a worker does when a scan does not match, a barcode will not read or the stock is not there. If the answer is "find a supervisor", the floor will slow down.
- Workarounds. If people keep a notepad in their pocket, something in the app is not working for them. Ask what it is.
How APFoodz handles it
The APFoodz warehouse app covers picking, receiving, putaway and counts on iOS, Android or a Zebra handheld, scanning with the phone's camera or the Zebra's built-in scanner. Pallet and case labels print to a Zebra or any other printer.
