Create a location database
Give every location a unique internal ID and store its approved public name, address, phone, location URL, hours, categories, manager contact, opening date, and status.
Do not manage locations as loosely copied rows across multiple spreadsheets.
Audit by location
Search each location independently and watch for cross-location duplicates, old phone numbers, closed branches, and profiles accidentally attached to the wrong location.
Large portfolios often justify a listings-management system because changes happen too frequently for ad hoc manual maintenance.
Plan openings and closures
New locations need a controlled launch sequence. Closed or relocated locations need a cleanup sequence so old listings do not continue sending customers to the wrong place.
