How to do barcode stocktaking with an iPhone

When you run a small shop or sell used items, stocktaking often turns into a slow loop: check the shelf, search the spreadsheet, write a number down, then calculate the difference later.

With barcode scanning on an iPhone, you can identify each item quickly and compare the expected quantity with the actual count on the spot. This guide shows the basic workflow and how StockLite fits into it.

Common reasons stock counts do not match

Stock differences usually come from missing records or an outdated baseline, not from a mysterious problem with the shelf itself. Start by narrowing down the likely cause.

  • Stock received or shipped was not recorded right away
  • Returns, samples, damaged goods, or personal use were not logged
  • Similar items were registered twice
  • The same shelf was counted twice, or a shelf was skipped
  • The expected quantity in the item master is already old

Why spreadsheet-only stocktaking gets painful

Spreadsheets are useful for planning and records, but they are not always comfortable on the floor. You have to search for the item, count the shelf, copy the number, and calculate the gap later.

You do not need to abandon Excel or Google Sheets. Exporting the sheet as CSV can turn your existing list into an item master. The part to improve is the on-site checking workflow.

What barcode stocktaking changes

The main value of barcode scanning is item identification. Scan the barcode, enter the actual count, and compare it with the expected quantity. This makes it easier to focus only on items that have a difference.

It does not make mistakes impossible, but it reduces searching, manual entry, and after-the-fact reconciliation.

Steps to compare expected stock and actual counts

The workflow is simple: prepare the expected stock, count the actual stock, then investigate only the differences.

  • Prepare a CSV with SKU, barcode, item name, and expected quantity
  • Import the CSV into an inventory app such as StockLite
  • Scan items on the shelf and enter actual counts
  • Check the difference between expected and actual quantity
  • Review only the items with a difference
  • Export the stocktaking result as CSV for your records

Prepare an item master with CSV

A small workflow does not need a complicated master file. SKU, barcode, item name, expected stock, and storage location are enough to start.

Pomeranian Studio provides a free inventory and stocktake CSV template. If you already have an Excel inventory sheet, align the columns and save it as CSV so it can become the source for your app workflow.

Notes for small shops and resale workflows

Items without barcodes can be registered manually or managed with your own labels. For used or one-of-a-kind items, it is often easier to separate SKUs and treat stocktaking as an available/not-available check.

Stocktaking exports can support your records, but tax and accounting requirements differ by business. Confirm the requirements for your own operation when needed.

Start stocktaking with only an iPhone

StockLite is a lightweight iPhone inventory app for barcode-based stocktaking. Import expected stock with CSV, scan items, and compare actual counts with your records.

It is designed for small sellers and small teams that want a simple workflow without a large inventory system. CSV export and AirDrop sharing are supported, with a one-time Premium upgrade instead of a monthly subscription.

FAQ

How should I count items without barcodes?

Register them manually or attach your own labels. You can still compare actual counts with your expected stock using SKU or item names.

Can I use my existing Excel inventory sheet?

Yes. Align the columns and save the sheet as CSV. SKU, barcode, item name, and expected quantity are the most important fields.

Can I keep the stocktaking result as a record?

Yes. StockLite supports CSV export. Use the file as an internal record, and check tax or accounting requirements for your own business.
