Many businesses start running their warehouse with spreadsheets and paper lists. With few items, limited orders and two or three people, that can be enough. The problem is that as you grow, the cost of spreadsheets becomes invisible: errors surface only when a customer calls, stock differences only at the count.
Comparison
| Topic | Spreadsheets and paper | Warehouse management software (Nitrogen PDA) |
|---|---|---|
| Stock accuracy | As current as the last entry; often end of day | Instant with every scan, same as Mikro ERP |
| Working at the same time | File conflicts, “which is the latest version?” | Everyone on the same data, with per-user permissions |
| Error prevention | Checks depend entirely on people | Instant warnings for wrong item, excess quantity, wrong location |
| Item location | A separate column of uncertain accuracy | By location, updated with every movement |
| Batch/lot and expiry | Tracked by hand, easy to miss | Checked at the moment of work, expired lots blocked |
| Documents | Dispatch notes and invoices retyped into the ERP | Created on the handheld, ready in the ERP |
| Audit trail | No record of who changed what | User and time recorded for every movement |
| Upfront cost | Low | Requires licences, setup and hardware |
Six signs it is time to switch
- Shipping errors turn into customer complaints several times a month.
- System stock and shelf stock often disagree.
- You close the warehouse for more than a day to count.
- Only certain people know where an item is.
- Dispatch notes and invoices are typed in from warehouse paperwork.
- You have to track batches, lots or expiry dates.
Making the switch easier
- Start with core processes: receiving, picking and shipping; locations and advanced features can follow.
- Start with the devices you have: Nitrogen PDA also works with phone and tablet cameras.
- Measure the cost: calculating today's cost of wrong shipments and manual entry makes the investment decision clear.
