Tax Information
Marketing services are generally taxable. Ad spend passthrough may be treated differently from service fees in some jurisdictions. Consult your accountant for proper treatment.
Industry context (2026)
US marketing agency rates in 2026: solo agencies $150-$300/hr blended; small agencies (3-10 people) $200-$450/hr blended; mid-market $400-$800/hr. Monthly retainers typically $5K-$50K for SMB clients, $50K-$500K+ for enterprise. Pass-through media spend (paid Google/Meta/LinkedIn ads) is sometimes marked up 10-15%; sometimes pure reimbursement (depends on contract). Agency services are taxable in some US states (TX, OH, WV); exempt in service-friendly states (CA, NY, IL).
Worked example
Acme Marketing (5-person agency) bills a B2B SaaS client monthly. April invoice itemizes: 'Marketing services retainer — April ($12,000/mo): SEO content (4 pieces) — $4,800; Email campaigns (5 sends) — $2,400; Social media management (Twitter/LinkedIn) — $2,800; Reporting & analytics — $2,000', 'Pass-through media spend: Google Ads (managed) — $4,200; LinkedIn Ads — $2,800', 'One-off: Landing page A/B test setup — $1,500'. Subtotal $20,500. Pass-through media is reimbursement-only (no markup) — 0% tax; agency services taxable per CA rules (but agency is in NY, services exempt). Net 30 from issue date.
Common mistakes to avoid
Lumping retainer + media spend on one line
Always separate agency labor from pass-through media spend. Different tax treatment, different expense codes for clients, and prevents disputes about media markup.
Vague retainer scope
Bad: 'Marketing retainer — April — $12,000'. Good: itemize what's included (channels, deliverable counts, hours capped). Without itemization, retainers drift into infinite scope.
Not tracking media spend separately
Pass-through spend should reconcile against actual ad platform invoices. Some agencies charge a 10-15% media management fee; some don't. Either is fine; consistency is what matters.
No overage handling defined
When a retainer client wants more work mid-month, what happens? Bill at a stated overage rate, roll to next month, or hard cap with work paused. State the policy on every invoice footer.

Frequently Asked Questions
How do marketing agencies typically bill?
Most agencies use one or more models: monthly retainers for ongoing work, project fees for campaigns, hourly rates for ad-hoc requests, and percentage of ad spend for media management. Retainers are the most common for established client relationships.
Should I pass through ad spend on my invoice?
Yes, list ad spend as a separate line item at cost, with your management fee shown separately. This transparency builds trust and makes it clear what the client is paying for services vs. media.
How do I invoice for a marketing retainer?
Invoice at the beginning of each month for the agreed retainer amount. Include a brief summary of deliverables for that month. If any work exceeded the retainer scope, itemize the additional charges.
