A monthly advertising proposal can be hard to compare when every provider groups its costs differently. One number may include management and media. Another may cover professional services while the ad platform bills you separately. Neither structure explains itself.
Before approving the work, ask for a simple breakdown of where the money goes and who receives it. That gives you a clearer view of the commitment and the decisions you control.
Separate media from the work around it
Media spend pays for placement through a platform such as Google Ads. Agency fees pay for agreed work: planning, campaign setup, creative, landing-page coordination, monitoring, analysis, or reporting. The scope should explain which of those activities are included.
Other costs may sit outside both categories. Photography, video production, call tracking, a landing-page build, or a reporting tool can require separate funding. Ask about these before the campaign starts, particularly if a low management quote assumes that your business already supplies the necessary assets.
Understand how platform budgets operate
An average daily budget is not always a hard daily spending cap. Google Ads explains that spending can vary by day and that monthly charging limits apply to most campaigns. Read the rules for your campaign type and agree on who may change the settings.
Use an account your business can access. Know who owns the account, how billing works, and what happens to campaigns and creative if the agency relationship ends. Those operational details matter as much as the fee percentage.
Compare deliverables and decisions
Ask how frequently performance will be reviewed, what triggers a change, and who approves additional spend. A fee without a clear service scope is difficult to evaluate. So is a long task list without a connection to the campaign's business objective.
Keep a small planning table with four columns: media, professional services, production, and tools. Put a monthly or one-time amount beside each, and mark any estimate that is still uncertain. You do not need complicated accounting to get started. You need a budget that makes the whole cost visible before the first advertisement runs.
