SKU anti-patterns
Common SKU mistakes that cost real money:
Common Scenarios:
- Generic numeric SKUs like "12345" that repeat across suppliers and cause merge conflicts.
- Meaningless random strings that warehouse staff cannot read at a glance.
- Characters such as / : spaces or accented letters that break Excel exports and feed parsers.
- No variant distinction - the same SKU for Size M and Size L, so orders ship the wrong item.
