Here’s how most experienced media buyers handle this:
If locations are separate campaigns/accounts
You quote based on the number of locations, even if creative is similar. Running separate campaigns means:
More setup and management time
Separate reporting and optimization
Multiple budgets and pacing
So you factor in additional management hours per location.
If locations share one ad account and budget
You can quote as one brand, since campaign structure is simpler. Even if you target different geos, it’s one dashboard, one set of invoices, and less overhead.
How to decide
Ask
Will each location have its own ad budget?
Do they need individual reporting and optimizations?
Are there unique offers or landing pages per location?
If yes, quote per location.
Even if the creative is nearly identical, separate campaigns = more work, more tracking, more accountability. Quote accordingly to cover your time.
