Manual entry costs more than typing time: every mistyped price or item code has to be found and fixed later, often after it has already affected invoices and reorder decisions. Barcode scanning removes the keying step where most of those errors start, and with a phone camera it costs nothing in hardware to try.
"We don't have that many items, typing them in is fine" sounds reasonable — until you count what manual entry errors actually cost once they ripple through prices, stock counts, and invoices.
Side by side
| Manual entry | Barcode scanning | |
|---|---|---|
| Speed per line | Several seconds to find and type a code or name | About a second per scan |
| Typical errors | Transposed digits, wrong item picked from a list, wrong price | Mostly limited to damaged or unreadable labels |
| When errors surface | Often weeks later, at reconciliation or a stock count | Immediately — an unknown or wrong scan is visible at the counter |
| Training needed | Staff must remember codes and prices | Point and scan |
| Setup cost | None | Labels for unbarcoded items; a phone camera works as the scanner |
Where the cost hides
The direct cost of manual entry is typing time. The larger, hidden cost is what happens when an entry is wrong: a mistyped price undercharges customers for weeks, a wrong item code attributes a sale to the wrong product, and a miscounted stock take throws off every reorder decision made from it until the next physical count.
An illustrative cost calculation
Plug your own numbers into this — the figures below are an example, not an industry benchmark:
| Input | Example |
|---|---|
| Lines entered by hand per day (sales + receiving) | 300 |
| Error rate | 1 in 100 lines |
| Errors per day | 3 |
| Average time to find and fix an error later | 10 minutes |
| Time lost per month (26 trading days) | 3 × 26 × 10 min = 13 hours |
That's before counting the money lost on undercharged prices or the sales lost when a wrong stock count means an item isn't reordered. Even if your error rate is half this, it's a meaningful amount of time spent fixing avoidable mistakes.
The time cost of fixing an error
An error caught immediately costs seconds. An error caught during a monthly reconciliation costs someone time to investigate, trace back, and correct — often across several records built on the wrong number in the meantime. The later an error is caught, the more it costs, and manual-entry errors are, by nature, caught late.
Where the switch pays off fastest
- High transaction volume — more lines means more chances to mistype.
- Frequent stock takes — scanning turns a counting day into an hour (see how to run a stock audit in under an hour).
- Thin margins — a small pricing error matters proportionally more.
- Several staff at the counter — scanning doesn't depend on anyone remembering codes.
A very low-volume business with a handful of SKUs may genuinely not need it yet — but that threshold is lower than most people assume, especially once scanning needs nothing more than the phone you already have.
StashBill's barcode scanning uses your phone or tablet camera — no dedicated hardware required to make the switch, and Bluetooth or USB scanners work too.
Frequently asked
Do I need special scanner hardware to start barcode scanning?
No — a phone or tablet camera can read standard 1D and 2D barcodes; a dedicated scanner is an optional upgrade for very busy counters.
What if some of my products don't have barcodes?
You can generate and print a barcode label for any item that doesn't have one, and scan it from then on.
Which barcode types are used on retail products?
Most packaged goods carry EAN-13 (or UPC-A in North America). Internal labels often use Code 128 or QR codes.
