Marketing Consultant Invoice Essentials

Marketing invoices often involve a mix of service fees and media pass-through costs. Keep these clearly separated on your invoice:

Service fee — your time and expertise (strategy, execution, reporting)
Media spend — ad budget passed through from platforms (Google Ads, Meta, LinkedIn)
Tool and platform subscriptions — SEO tools, scheduling software, analytics platforms billed to the client
Creative costs — copywriting, design, or video production if outsourced
Billing period — marketing retainers are almost always monthly

Separating services from media costs makes it easier for clients to understand where their budget goes and for you to demonstrate ROI.

Retainer vs Project Billing for Marketers

Monthly retainer: The most common model for ongoing SEO, social media management, PPC, or content marketing. Fixed fee for a defined scope — e.g., "SEO retainer: technical audit, 4 blog posts, monthly report — €2,500/month". Invoice at the start of each month.

Campaign billing: Fixed fee for a defined campaign with a start and end date. Invoice in milestones: 50% at campaign launch, 50% on completion and reporting.

Performance-based: Some marketers charge a base retainer + performance bonus. Structure this clearly: "Base fee: €1,500. Performance bonus: €500 (paid when leads exceed 50/month)". Invoice base fee monthly; performance bonus when earned.

Hourly consulting: For strategy sessions, audits, or one-off advice. Log time precisely and invoice at your agreed rate.

Invoicing for Media Pass-Through Costs

When you manage ad spend on behalf of clients, handle billing carefully:

Pass-through at cost: Charge the exact media spend with zero markup. Add a clear line item: "Google Ads spend — March 2025 — €3,847.50 (at cost)"
Pass-through with markup: Some agencies add a 10–15% management fee on top of media spend. Disclose this practice clearly and reference it in your contract.
Separate invoicing for media: Some agencies invoice their service fee separately from media spend. This keeps things clean and avoids tax complications.

Always attach a platform screenshot or report showing the actual spend when billing for media pass-through costs.

Tax for Freelance Marketers

Marketing services are standard-rated for VAT/GST purposes:

EU marketers: Standard VAT rates apply (19% DE, 20% FR, 21% ES/NL, 22% IT). Cross-border EU B2B invoices use reverse charge — include both VAT numbers and add "Reverse charge — Article 196 EU VAT Directive".
UK marketers: 20% VAT on all marketing services once registered. Media pass-through costs are also subject to VAT.
US marketers: Marketing services are generally not subject to sales tax, but digital advertising and SaaS tools may be taxable in some states. Verify your state-specific rules.

Frequently Asked Questions

Should I invoice for media spend separately from my service fee?

Yes — keeping service fees and media spend separate on the invoice makes things clearer for the client and avoids complications where different tax rules might apply. Issue one line item for your service fee and one (or more) for media pass-through, clearly labelled.

How do I invoice a performance-based bonus?

Wait until the performance conditions are met (verified by agreed metrics), then issue a supplementary invoice or include the bonus as an additional line item on the next regular invoice. Reference the specific metric and the period in the description.

What payment terms are standard for marketing retainers?

Retainers are typically invoiced in advance (at the start of the month) with Net 7 or Net 14 terms. This protects you — you've delivered work before payment is due, but you haven't waited 30 days. For new clients, consider requiring the first month's payment upfront before work begins.

Can I use invoicePrivate for multiple clients with different currencies?

Yes. Each invoice can have a different currency. Your previous invoice settings are saved locally, making it easy to create a new invoice for any client. Switch the currency in the invoice editor for each client.
