SKUs uniquely designate an article; to make them speaking follow these rules:
- Keep huge spaces between each article, do not continously number SKUs as e.g. 1, 2, 3. You will then be able to add further articles at the right place later on.
- Use full blocks of numbers for what belongs together, e.g. 1000-1999 for normal bread, 2000-2999 for special bread, 3000-3999 for small bread.
- Use the same numbers at the same position for same values, e.g. 0 at the last position for big and 5 for small or 1 at the second last position for meat, 2 for cheese, 3 for fish and so on.
- And we cannot repeat it enough: leave much space between SKUs. To keep everything in good order saves you 100 times what it took to figure outthe numbers and it looks clear and well organised.
