Marketing Agency Invoice Example with Annotated Line Items

Sample marketing agency invoice

This is an illustrative invoice from a fictional Austin agency. The prices are the agency's own, not a market benchmark.

The arithmetic: $6,500 + (8 × $350 = $2,800) + $2,200 + ($12,000 × 0.15 = $1,800) + $12,000 + (2 × $600 = $1,200) + (2 × $450 = $900) = $27,400. Of that, $15,400 is agency fees and $12,000 is the client's media budget.

Payment Terms: Net 15. Bank transfer or ACH. Media spend is billed at cost and is due regardless of campaign performance. Under the services agreement, campaigns may be paused if an invoice is more than 15 days overdue.

Notes: March performance report sent separately by email. Google Ads delivered 14,200 clicks at an average cost per click of about $0.85 ($12,000 ÷ 14,200 = $0.845). Recommended April media budget: $14,000, pending approval.

Field-by-field breakdown

• From: Agency legal name, office address and accounts email.
• To: Client company, billing contact and address.
• Account reference: Ties the invoice to the client account, campaign period and contract.
• Retainer line: A flat monthly fee for strategy, meetings and account management. Say which month it covers and whether it is billed in advance.
• Deliverables: Each content type (blog posts, emails, videos) on its own line with quantity and unit price.
• Management fee vs. media spend: Keep your fee (your revenue) and the media budget (the client's money) on separate lines. Put the basis of a percentage fee in the description so the client can check it against the platform's report.
• Spend at cost: Reference the platform invoice so the client can match the amount exactly. If you add a markup, show it as its own line rather than inside the spend.
• Tax note: Whether sales tax applies to any of these lines depends on the state and on how each service is delivered, and spend, fees and content may be treated differently. This example does not charge tax; check your state's rules or ask an adviser. In the UK, see the VAT worked example below. This is general information, not tax advice.

How the prices on this invoice were set

There is no reliable public rate card for agency work, so this example does not include a "typical rates" table. Our marketing agency pricing guide builds a blended hourly rate from salaries, payroll costs, overhead and billable hours, then prices retainers and management fees from planned hours.

For context only, the US Bureau of Labor Statistics estimates a median wage of $37.87 an hour (mean $43.03) for market research analysts and marketing specialists in May 2025 (BLS Occupational Employment and Wage Statistics). An agency rate has to cover payroll taxes, benefits, overhead and non-billable time on top.

Variations

• Retainer only: Some agencies bill a single retainer line that covers all services, with a short work summary in the notes.
• Project-based: One-off campaigns billed as a flat project fee with milestone payments.
• Flat management fee: Instead of a percentage of spend, a fixed monthly fee based on the hours the account takes, which does not grow when the client spends more.
• Client-paid media: The client pays the ad platforms directly on its own account, and your invoice carries only fees.
• International clients: State the currency and check whether VAT applies, including any reverse-charge wording the client's country requires.

Tips for marketing agency invoicing

1. Separate media spend from agency fees so your revenue and the client's media budget are both visible.
2. Send a performance report with each invoice so the client can see what the fees paid for.
3. Pick a fixed billing date, for example the 1st of the month, with the retainer in advance and usage-based fees in arrears.
4. Watch card fees on pass-throughs. Stripe's standard US pricing is 2.9% + 30¢ per successful domestic card payment (Stripe pricing), so a $12,000 spend line paid by card costs $348 in percentage fees alone ($12,000 × 0.029). Ask for bank transfer on invoices with large pass-throughs.

Worked example: the spend line for a UK VAT-registered agency

In the UK, a cost you pass on to a client can be left out of the value of your own supply, and so carry no VAT from you, only if it qualifies as a disbursement. HMRC's conditions include that you acted as the client's agent when paying, the client was responsible for paying the supplier, you recover only the exact amount you paid, and the cost is itemised separately on your invoice (HMRC VAT Notice 700, section 25). Costs that do not qualify are part of your taxable supply and carry VAT like your fee.

Take the same March invoice in pounds for a VAT-registered London agency at the 20% standard rate:

The arithmetic: £15,400 × 0.20 = £3,080; £12,000 × 0.20 = £2,400. Which column applies depends on the facts, such as whose name the ad account is in and who the platform bills, so check the conditions with HMRC's guidance or an adviser. Last reviewed: October 28, 2026.

Building this invoice in InvoiceQuickly

• Line items with quantity × unit price for the retainer, the management fee, each platform's spend and other deliverables. It does not calculate percentage fees or import ad spend, so enter the amounts you worked out and put the basis in the description.
• One tax percentage per invoice, calculated on the subtotal after any discount. If the fees and the spend are taxed differently, put them on separate invoices.
• Notes and terms (up to 5,000 characters each) for the contract reference, the pause clause and campaign results.
• Pro ($9/month) adds email delivery, payment links through your own Stripe or PayPal account, and recurring schedules for the retainer. The recurring form creates one line item with no tax and 30-day terms, so usage-based lines go on a separate invoice.

It does not attach reports, connect to ad platforms or track hours. Start from the marketing agency invoice template.

Frequently asked questions

Should we bill media spend in advance or in arrears?

If your agency pays the platforms, billing the media budget in advance (or asking the client to pay the platforms directly) means you are not financing the client's ads. Billing in arrears at cost is simpler to reconcile but leaves you carrying the spend until the client pays. State the choice in your contract and on the invoice.

How do we handle scope creep on retainer accounts?

Define what the retainer covers in your statement of work, ideally with an hours cap. Bill work beyond it as separate lines at your stated rate, with the date it was approved. Our scope creep guide covers the conversation.

Is media spend taxable?

It depends on where you are and how the spend is arranged. In the UK, spend passed on at exact cost is outside your VAT only if it meets HMRC's disbursement conditions; otherwise it carries VAT like your fee. In the US, sales tax rules on advertising and digital services vary by state, so check your state's guidance before deciding how to invoice it.

Should a management fee be a percentage of spend or a flat fee?

Either works if the contract states it. A percentage should come with a monthly minimum and the calculation on the invoice; a flat fee based on the hours the account takes is simpler and does not rise when the client spends more. The pricing guide compares both on one account.
