Advertising agencies, from solo creative directors to small shops of five to twenty people, bill clients for campaign strategy, creative development, media planning and buying, and production. Invoices often combine labor, pass-through media spend, and third-party costs like photographers, printers, or ad platform fees. Getting these lines separated clearly is what keeps clients from questioning the total.

Agencies price in several ways, often mixed on one account. Monthly retainers are the most common for ongoing clients and cover a set scope of hours or deliverables. Project fees are used for campaigns, brand launches, and video or print production. Hourly billing, usually tied to a rate card by role (strategist, art director, copywriter, account manager), is used for out-of-scope work and for clients who want transparency. Media buying is typically billed either as a percentage of ad spend (commonly 10-20%) or as a flat management fee, with the media cost itself passed through at cost. Third-party production costs such as talent, stock licensing, printing, and studio rental are usually billed at cost plus a markup of about 10-20% for handling and coordination. Many agencies also add a rush fee for work with turnaround under a few days.

Notes: Payment due within 15 days of invoice date. Ad spend is billed at cost and is non-refundable once served. Out-of-scope work was approved by email on March 12. Late balances accrue 1.5% interest per month.
Larger clients route invoices through accounts payable, which often rejects invoices without a matching PO or job code.
Clients want to see what is your labor and what is pass-through, and it makes any markup easy to defend.
Ties charges to specific dates, which helps when a client reconciles against ad platform statements.
Lets you point to agreed terms if the client questions a line, especially for out-of-scope additions.
Shows how the rate card was applied and backs up any hourly or overage billing.
Licensed assets often have time, territory, or channel limits. Stating them prevents misuse and later disputes.
Some states tax certain advertising or creative services and others do not. Check your state rules and show tax as its own line if charged.
Retainers are usually billed at the start of the month, due in 7 to 15 days. New clients commonly pay a 25-50% deposit on project work, with the balance split across milestones such as concept approval, production, and delivery. Media spend is often invoiced in advance or paid by the client directly to the platform, because agencies do not want to float tens of thousands of dollars in ad costs. Net 30 is common with larger corporate clients, but it is reasonable to ask for net 15 from small businesses. Late fees of 1-1.5% per month are standard if written into the contract. Payment is typically by ACH, wire, or credit card, and some agencies add a surcharge for cards on large invoices.
If you pay for ads on your own card and invoice later, you carry the risk. Ask for prepayment of media, or have the client set up their own ad accounts and add you as manager.
State the hours or deliverables included each month and what happens to unused time. Without this, clients assume unlimited revisions and rollover.
A short email approving extra hours or costs is enough. Reference it on the invoice so the charge is never a surprise.
Invoice at concept approval, shoot or build completion, and final delivery rather than waiting until the campaign launches. Delays on the client side then do not hold up your cash.
Attach or keep copies of printer, talent, and platform invoices so you can answer any question about pass-through costs quickly.
Most agencies either pass media through at cost and charge a separate management fee, or build a commission into the media price. Whichever you choose, state it in your agreement. Hidden markups damage trust and can violate client contracts that require transparency.
That depends on your contract. Many agencies bill the full retainer regardless, since it reserves capacity. Others allow limited rollover for one month. Write the rule into your agreement and note it on the invoice if hours are unused.
It varies by state. Some states tax advertising, design, or certain digital services, while many do not tax professional services at all. Check with your state revenue department or an accountant, and show any tax as a separate line.
For projects, invoice at milestones set in the contract, such as a deposit at signing, then at approval and delivery. For retainers, invoice at the start of the billing month. For media, invoice before the spend occurs where possible.
Your contract should say you are paid for work performed, not for specific outcomes such as sales or leads, unless you agreed to performance pay. Point to the scope of work and the deliverables completed, and offer to review strategy going forward.
