Marketing invoice template: Fees, ad spend and overages
Split your fee by service, keep ad spend reimbursements on their own lines, bill approved overages separately, and download a PDF, Excel or Word file. For single-channel work, see the SEO and social media templates.
What the marketing invoice starts with
Each version opens in the online maker with its own line items and payment terms, and downloads as an editable Excel or Word file. Example amounts are hypothetical, not market rates.

Fill in your marketing invoice

A marketing invoice has to separate your fees from money you spend for the client, such as ad budgets and tools. Mixing them makes the invoice harder for the client's finance team to check and approve. The sections below cover line items, fee structures, ad spend and payment terms.
What the marketing invoice covers
What you can do with this template, and what it does not do.
Management fee by channel
Give each channel its own fee line (paid search, paid social, email, content) so the client can see where the retainer goes.
Ad spend as pass-through
If you pay the platforms, bill ad spend on separate lines at cost, with any markup on its own line.
Retainer overages
Bill approved work beyond the monthly scope as a separate line with hours and rate.
Tool and software costs
Pass through client-specific tools (landing page builders, call tracking, data subscriptions) at the price agreed in the contract.
Report reference
Mention the monthly report in the notes. The invoice is for billing; results belong in the report you send with it.
Completed example and downloads

How to fill in your marketing invoice
A marketing invoice lists your fees by service, keeps spend made for the client apart, and names the period it covers.
- Your business name and tax or VAT number if registered
- Contact information and website
- Client name, company, and billing contact
- Invoice number and date
- Campaign or project name
- Service period covered
- Detailed breakdown by service type (SEO, PPC, social, content)
- Hours worked per service category
- Ad spend management fees (if applicable)
- Third-party tool costs passed through
- Reference to the monthly report (results belong in the report, not the invoice)
- Retainer allocation and overages
- Payment terms and due date
Practices that make marketing invoices quick to approve.
- Separate management fees from ad spend on every invoice
- Bill retainers on the schedule in your contract (often the start of the month)
- Show how the fee is split across services (paid media, email, content)
- Attach or link the monthly report instead of putting results on the invoice
- Track time by client and service so you know which retainers are profitable
- Bill strategy work separately from execution if your contract prices them separately
- Get written approval before spending above the agreed budget
- Invoice campaign milestones as soon as they are reached
- Send a reminder before the due date and follow up as soon as it passes
Marketing fees vary by channel, market and spend level, so this section covers structures rather than market rates. Pick the one in your contract and invoice it the same way every month.
- Flat monthly management fee per channel: predictable for both sides; bill in advance
- Percentage of ad spend: state the base (planned or actual spend) and the percentage in the line description
- Flat fee with a minimum plus a percentage above a spend threshold: common when budgets swing month to month
- Project fee for launches or campaigns: billed by milestone
- Hourly for ad-hoc work outside the retainer: bill in arrears with approved hours
- Example (hypothetical): $2,500 management fee + 10% of spend above $20,000. With $26,000 March spend, the invoice shows $2,500 + $600 = $3,100 in fees, plus $26,000 media if you paid the platforms
These are common options to agree with the client, not rules. Whatever you choose belongs in the contract first; the invoice repeats it.
Monthly retainers:
- Invoiced at the start of the month, due within the terms you agreed (for example Net 15)
- First month paid before work begins, for new clients
Project work:
- A deposit, then milestone or completion payments
Ad spend:
- The client pays platforms directly, or prepays you, or reimburses you at cost
- Any markup on spend stated in the contract and shown as its own line
Late payment:
- Whether campaigns pause while an invoice is overdue
- Late fees or interest only if the contract includes them and local law allows
