What should a marketing consultant put on an invoice?
Marketing consulting invoices name the work delivered, such as a strategy plan, a campaign setup, or an audit, and tie the charge to a project fee, an hourly rate, or a retainer. List research, creative, and reporting separately. Reference the campaign or period so the client can track the spend.
Your invoice needs to show exactly what work you did during the billing period. Break down hours by activity like strategy sessions, campaign development, content creation, or reporting. Marketing clients often manage multiple vendors and need this detail to match invoices against their approved scope of work. Their finance teams will reject vague line items. Include any pre-approved expenses like stock photos, software subscriptions, or ad spend you covered upfront.
Most marketing consultants charge a monthly retainer or bill by the project. For retainers, invoice at the start of each month for that month's work. For projects, ask for 50% upfront and 50% on completion, or split payments across milestones. Set net 15 or net 30 terms depending on client size. Bigger companies move slower but pay reliably once you are in their system.
Send invoices the same day each month so clients expect them and budget accordingly. The biggest mistake is waiting until you finish all deliverables to bill for a long project. You will wait months for payment and kill your cash flow. Invoice monthly even on project work, marking it as partial payment against the total.

How the work is charged
Marketing consultants commonly quote a project fee for defined work, an hourly or day rate for advisory, and a monthly retainer for ongoing campaigns. Ad spend is usually billed separately from the management fee.
Payment terms and deposits
Project work frequently bills a deposit upfront with the balance on completion. Retainers bill monthly in advance, and business clients usually pay on net terms.
Tax and compliance
If you are registered for sales tax or VAT, show it as a separate line with your registration number. Serving clients in other countries can change how tax applies, so confirm what applies to you.
Frequently asked questions
How do marketing consultants charge?
Marketing consultants charge $100–$300/hour, project-based ($3,000–$20,000 for a strategy), or monthly retainers ($2,000–$10,000). Some charge a percentage of managed ad spend.
What should a marketing consulting invoice include?
Include strategy deliverables, campaigns planned, channels analyzed, research conducted, ad spend (if managed), and any tools or subscriptions used. Separate strategy fees from execution.
Should marketing consultants handle execution or just strategy?
Clarify this upfront. Strategy-only engagements are billed at higher rates. Execution (managing ads, creating content) is separate. Some clients want both — offer bundled pricing.
