Tracked hours flow straight into a polished invoice — no copy-paste, no manual math.
Marketing invoices turn campaign work into a document the client can approve, pay, and file. Use them for monthly retainers, one-off projects, PPC management, content production, brand work, consulting, or mixed engagements that combine fixed fees and billable time. The invoice should identify the project, seller, client, invoice number, issue date, due date, line items, subtotal, applicable tax, total due, accepted payment methods, and payment terms.
The invoice also needs enough detail to match the client's approval process. A vague line such as "marketing services" invites questions. A useful line names the work and pricing basis, such as "June paid search management, flat monthly fee," or "Campaign landing-page writing, 6 hours at $125 per hour." Clear wording helps the client route the invoice to the right budget, purchase order, or project owner.
Marketing teams commonly bill through hourly rates, fixed project fees, retainers, value- or performance-based fees, or a mix of models. Hourly invoices may use one blended team rate or separate specialist rates by role. Retainers commonly charge a recurring monthly fee for a predetermined amount of billable time or a set of monthly deliverables, usually paid upfront on an agreed date.
Project-based marketing invoices often use deposits and milestones to protect cash flow. A common split is 50% upfront and 50% on completion. Longer projects can invoice at strategy approval, design delivery, or campaign launch. PPC management often uses a fee equal to 10% to 30% of monthly ad spend, with the campaign budget shown separately from the management fee.
The United States has no national VAT or GST invoice regime and no single federal private-sector invoice format. For ordinary businesses, invoices support tax and accounting records by showing income, expenses, amounts, and gross receipt sources. Sales and use tax comes from state and local rules, and the correct treatment depends on nexus, service taxability, the place of sale, and the buyer's location.
Marketing services do not follow one national sales-tax rule. California generally taxes retail sales of tangible personal property and only some service or labor charges, while Texas defines 16 broad categories of taxable services. State-level registration may also matter when taxable sales are made. Use the invoice tax line to show the applicable tax clearly, and use terms such as payment due 30 days after issue only when that matches the contract.
A free invoice tool works well for a one-off marketing invoice when the amounts are already approved and the tax treatment, scope, and payment terms are known. It is enough for a single retainer invoice, a final milestone invoice, or a flat-fee campaign invoice that needs a clean PDF or export for the client.
A managed workflow becomes necessary when tracked billable time per client or project drives the invoice. Everhour supports billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and reports for billable time, non-billable time, billable amount, and cost. That structure helps marketing teams separate client work from internal meetings before billing.

Use the model that matches the engagement. Monthly retainers fit ongoing work with recurring hours or deliverables. Fixed project fees fit defined campaigns or deliverables. Hourly billing fits advisory work, production overflow, and undefined scope. Milestone billing fits longer projects where payment should follow strategy approval, design delivery, campaign launch, or another agreed checkpoint.
Each line should name the service, pricing basis, quantity, unit price, and line total. For hourly work, include the role or service and the hours billed. For flat-fee work, describe the deliverable or campaign phase. For PPC management, separate the management fee from ad spend so the client can distinguish agency fees from media budget.
Marketing retainers are commonly paid upfront on an agreed date. That gives the agency predictable recurring revenue and reduces payment risk. The invoice should state whether the retainer covers a set number of billable hours, a fixed bundle of monthly deliverables, or both. Extra work should appear as a separate line when the contract allows it.
A United States marketing invoice does not use a national VAT or GST number because the country has no national VAT or GST invoice regime. Sales and use tax is state and local. The invoice should show applicable sales tax only when the seller's obligations, the service type, nexus, and place of sale require collection.
The most common mistake is mixing billable client work, internal strategy time, and pass-through costs without clear labels. A client should be able to see the project, period, service, rate, tax line, total due, and payment deadline. Separate internal non-billable time from client-facing charges before the invoice is sent.
Everhour lets admins set billing status at the project level, mark specific tasks as non-billable, use custom task rates, and set member-rate exceptions. Reports can show billable time, non-billable time, billable amount, and cost, so marketing invoices reflect approved client work instead of every logged activity.
Everhour Billing & Invoicing turns tracked billable time and expenses into invoices, with line items grouped by structures such as project, task, person, or date. Invoiced time is marked as invoiced, which keeps the same approved work from appearing again on a later client invoice.
Track client work, exclude non-billable tasks, and invoice approved marketing hours with Everhour, so billing reflects the work clients agreed to pay for.
