How to label a small business, properly
Start with places, not things.
The highest-leverage labels are on shelves, bins and drawers: a scanned shelf shows what lives there, which makes put-away self-explaining for anyone on the crew. Label the places first, then the expensive or wandering things - tools, cameras, cases - and let boxed stock keep its manufacturer barcode.
Pick sizes by reading distance.
25 mm QR squares scan fine at arm's length; use 38 mm or larger for anything read across a room, in bad light, or with gloves on. Always keep the human-readable name and code under the QR - when a label is half-worn, the text is the fallback.
Match the material to the room.
Paper sheets are fine for office shelves; laminated or synthetic labels survive vans, workshops and weather. Avoid wrapping labels around tight curves - a flat tag zip-tied to the handle beats a stretched sticker every time.
Print in batches, attach as you go.
Generate a sheet here (Avery layouts work on any office printer), stick labels during a normal week, and don't aim for a big-bang labelling day. In ItemTally every item gets a QR identity automatically at creation - the printed label just makes it physical.
