Common Marketing Consultant Invoicing Mistakes

Invoicing should be simple, but messy details can stall payment. Use these quick fixes to keep cash flowing and avoid disputes.

Mistake

How to fix it

Leaving out the service period, so clients don’t know what work the invoice covers.

Add start and end dates for the billed period on every invoice to tie charges to time.

Combining labor and expenses into one lump sum, which hides costs and invites pushback.

Split professional time from approved expenses and summarize each clearly to show value.

Write plain language descriptions that match the client’s words in the SOW and keep them short and specific.

Include your tax or VAT/GST number and any required business IDs, and apply tax to services or expenses only where it’s required. Check local rules.

Not referencing the client’s PO or SOW, which makes reconciliation harder.

Add the PO or SOW identifier on the invoice header so finance can match it fast.

Math or rate errors that undermine trust.

Use a time log or rate table to calculate totals, and double-check subtotals, tax, and the grand total before sending.

Marketing Consultant Invoice FAQs

Billing for retainers, ad spend pass-through, workshops, change orders, tools, late fees, and IP rights, tuned for U.S. clients. Includes one Marketing Consultant Invoice Template mention for clear answers.

How should I bill a monthly retainer vs a fixed project?

Use a monthly retainer for ongoing management. Use a fixed fee for a defined deliverable. Example line item: “Monthly Retainer: 20 hours of campaign management: $3,000.”

Can I pass through ad spend and media buying fees?

Yes. Keep ad spend separate from your service fee and note any agency or marketer markup. Example line items: “Ad Spend: Meta: $5,000” and “Media Buying Fee: 15% of spend: $750.”

How do I price and bill a brand strategy workshop or discovery?

Charge a flat workshop fee plus prep and deliverables. List the workshop day and the deliverable separately. Example line items: “Brand Strategy Workshop: 1 day: $2,000” and “Insights Deck: 25 slides: $900.”

How do performance bonuses work in marketing engagements?

Tie the bonus to a clear KPI and time window. State the trigger and the calculation. Example line item: “Performance Bonus: CPA ≤ $35 for 30 days: $1,200.”

What’s the clean way to handle scope creep or change requests?

Use a written change order with new fees and timelines before work starts. Track incremental hours or a flat add-on. Example line item: “Change Order: Extra landing page variant: $450.”

Do I charge sales tax on services in the U.S.?

Rules vary—check local rules. Some states tax certain services or digital goods. Example line item if taxable: “Marketing Services (Taxable): $4,000; Sales Tax: 7%: $280.”

How should I bill third-party tools, software, or stock assets?

Bill them as pass-through expenses with receipts, plus an admin fee if you use one. Separate them from your fee. Example line items: “Ahrefs Subscription: 1 month: $199” and “Procurement Admin Fee: 5%: $9.95.”

How should I word late fees on the invoice?

State your net terms, grace period, and the fee or monthly interest. Keep it short and legal-friendly. Example line item: “Late Fee: 1.5% per month after 15 days: $24.”
