SHOPIFY TOOL · INVENTORY · LIVE DEMO

Every comic scanned, boxed, and findable.

A barcode-driven inventory tool for comic stores on Shopify. Scan a comic and its storage box to record where it lives, find any issue in seconds, audit boxes against what Shopify expects, and print your own barcode labels — from a desktop scanner gun or a phone camera.

Longbox Scanner — overview
WHAT IT DOES

The problem — and the fix.

Comic stores track thousands of single issues across rows of long boxes, and the usual answer is a spreadsheet nobody trusts. Longbox Scanner replaces it with a scan-first workflow: comic, box, done — the location is saved to the product itself in Shopify, so there's no second database to maintain.

Finding is just as fast: scan any issue to see every box it lives in, or scan a box to list its contents. Audit mode reconciles a physical box against Shopify and flags strays with a one-tap fix, and the built-in label generator prints scannable barcodes for every box in the store.

Features

BUILT TO SOLVE ONE PROBLEM WELL
Scan-first workflow
Built for barcode guns: big inputs, auto-advancing focus, and loud beep-and-flash feedback.
Multi-box locations
A comic can live in several boxes at once — assign adds, move replaces, one tap removes.
Audit mode
Scan a box, then everything in it: see what's missing and reassign strays on the spot.
Label printing
Generates print-ready Code 39 barcode labels for boxes — verified scannable, cut lines included.
Phone camera scanning
No scanner gun? Every field has a camera button — native detection with a bundled decoder fallback.
Shopify is the datastore
Locations live on the product as a metafield — visible and editable in Shopify admin.
