Standardize before lists merge
- Require location-level exports. Verify each store or territory before it rolls into the national database.
- Tag the source location. Keep location codes attached so quality problems can be traced and fixed with the right operator.
- Clean promotion and POS lists. Paper forms, local giveaways, and point-of-sale capture are where errors build fastest.
- Block invalid records before brand sends. A dirty local list should not damage the sender reputation every franchisee depends on.
- Use API checks for new intake. Verify web leads, appointment forms, and loyalty signups as they enter the central system.
