Practical checklist
- Separate markup from profit margin; they are not the same percentage.
- Confirm whether sales tax is included in a displayed price.
- Test discount math before publishing promotions.
- Check the final customer total, not just the base price.
- Document assumptions so staff calculate prices consistently.
