About Countlark

Last updated 2026-10-25

Countlark is a set of browser tools for people who count things: a shop owner with a shelf of stock, a bar manager with half-empty bottles, an office with laptops to account for, a workshop where tools go out and should come back. Each page does one job and works straight away, without an account.

What is here

  • Trackers for a small shop, a bar, company assets and lent-out tools, all sharing one stock list in your browser.
  • Sheets and counts: an inventory spreadsheet generator, printable lists, count sheets that report the gap between book and counted stock, and a cycle count planner.
  • Scanning and labels: count by scanning barcodes with a phone camera or a USB scanner, log scans to a spreadsheet, print barcode labels on common label sheets.
  • Planning calculators: reorder point, safety stock, ABC analysis and stock aging, for one item or a whole list.

How it works

  • Your stock list stays on your device. It is kept in this browser’s storage. Nothing you type, scan or import is uploaded. Clearing the site data in your browser deletes it, so use the backup and export buttons.
  • The camera is optional. It is used only when you press a scan button, and frames are read on your device and not stored or sent.
  • Numbers are calculated, not typed in. The examples on each page come from the same code the tool runs, and that code is tested against independently worked answers.
  • Count and list templates are tally templates, not statutory books of account. Rules for the formal inventory records differ by country; check them with your accountant.
  • Third-party code is listed with its licence on the credits page.

If a tool gives a wrong result, please tell us through the contact page.
