Financial Transparency Checklist for Agencies and Clients

A Profit-First Marketing resource from Best Practice Media

Your agency can make better decisions when it understands what your business keeps from a sale. Use this financial transparency checklist to bring your agency, marketing lead, and finance lead into the same conversation before setting campaign targets.

How to use it: Copy these prompts into your onboarding document. For each item, record the answer, the person responsible, and when it will be updated. Start with your CFO, controller, bookkeeper, or whoever owns the numbers.

1. Agree on what success means

• Define the business outcome: contribution dollars, profitable new customers, repeat purchases, or another agreed goal.
• Agree on the definition of revenue, including how discounts, refunds, returns, shipping charges, and taxes are treated.
• Ask finance to define contribution margin and document the costs included. Label clearly whether a figure is before or after advertising spend.
• Separate the amount available to spend on acquiring an order from the amount the business needs to retain for overhead and profit.

Ask together: “What needs to be left after this sale for growth to be worthwhile?”

2. Bring the costs outside the ad dashboard into view

• Product costs by product or category, including relevant freight or duties.
• Packaging, fulfillment, payment processing, and shipping subsidies.
• Influencer, affiliate, marketplace, or other commissions paid per sale.
• Discounts, expected returns, refunds, and other costs that change the economics of an order.
• Agency fees, creative production, and other marketing expenses, with an agreed place in the overall profitability review.
• For service businesses: delivery labor, subcontractor costs, capacity, and differences in margin between services.

Check for overlap: Have finance confirm that a cost has not been counted twice. A platform’s reported return on ad spend does not, by itself, show what remains after these costs.

3. Share useful information with clear boundaries

Financial transparency can begin with a focused summary. Your agency needs enough information to make the decision in front of it.

• Choose the level of detail: product margins, category ranges, or finance-approved acquisition targets.
• Document any limits. A broad average can hide products that cannot support the same advertising spend.
• Agree who can access the information, where it will be stored, and what confidentiality terms apply.
• Provide a redacted P&L when it helps explain the wider business, with finance identifying what is relevant.
• Set a process for updating shared information when pricing, costs, commissions, or product mix changes.

Start with: “Here are the margin assumptions you can use, what they include, and who to ask when something changes.”

4. Turn the numbers into campaign decisions

• Agree on acquisition targets by product, category, or service where economics differ.
• Identify inventory, fulfillment, and delivery-capacity limits before increasing spend.
• Separate observed repeat-purchase performance from assumptions about future customer value.
• Name the reporting source and time period for each metric. Reconcile platform-attributed sales with business results rather than adding overlapping platform totals together.
• Document who can approve a budget increase and what evidence they need.

Illustrative discussion: Two products each sell for $100. Finance calculates that one leaves $45 before advertising, while the other leaves $20. The same acquisition cost can have very different consequences. Ask what each product must retain after advertising before setting its target.

5. Hold a 30-minute monthly finance-and-marketing review

1. 5 minutes — What changed? Review costs, prices, promotions, commissions, returns, and capacity.
2. 10 minutes — What did the business keep? Compare campaign reporting with finance’s agreed contribution measures. Identify missing data and explain differences.
3. 10 minutes — What will we change? Decide which products, offers, budgets, or assumptions need attention.
4. 5 minutes — Who owns the next step? Record each action, owner, due date, and approval needed.
