How to Invoice as a Copywriter: Projects, Rounds, Rights

A copywriter's invoice goes to a marketing manager who approves it and a finance team who pays it, and neither was in the briefing call. The invoice has to show what was bought: which assets, how many variants, how many revision rounds, and what the client may do with the words. "Website copywriting: $4,800" gets queried. "Homepage, 4 service pages and About page; 2 revision rounds included; ownership transfers on full payment per agreement of 3 March" gets paid.

This guide covers commercial copywriting for businesses and agencies: website projects, email and ad work, and retainers. Freelance journalists and authors billing per-word commissions, kill fees and royalties should read invoicing for writers and authors instead. Prices below are made up to show the arithmetic, not market rates. For setting your prices, see how to price copywriting.

What should a copywriting invoice include?

The basics: your business details, the client's legal name, an invoice number, the issue and due dates, line items, the total and how to pay (how to write an invoice covers them). For copy work, add:

• The project or campaign name and the client's PO number, if the client uses purchase orders. Agencies often cannot pay an invoice without one.
• One line per deliverable: "Homepage", "Service page: Bookkeeping", "Welcome sequence, 5 emails". Asset counts let the client match the invoice to what is in their CMS or email tool.
• Variants as quantities: "LinkedIn ads: 3 hooks × 2 body versions = 6 ads". Testing teams budget per variant.
• Revision rounds included, and any extra round as its own line with the date it was requested.
• Strategy and research time separate from drafting, so the drafting fee is not inflated by a workshop the client also bought.
• Usage or ownership terms, in one sentence that quotes your agreement (see below).
• Pass-through costs such as stock image licences or a transcription service, at cost or with the markup your agreement states.

Worked example: a website project billed in two invoices

Hypothetical example. A bookkeeping firm signs a $4,800 website copy project on 3 March. The agreement sets 50% on signing and 50% on approval of final copy, two revision rounds per page, $250 per extra round, and ownership of the final copy passing to the client on full payment.

Invoice 1, issued 3 March, due on receipt: one line, "50% of website copy project per agreement of 3 March (project total $4,800)": $2,400.00.

Invoice 2, issued on approval, due in 14 days:

Check: 300 + 1,400 + 2,600 + 500 = 4,800; 4,800 × 50% = 2,400; 2,400 + 250 = 2,650. The extra round carries its request date, which answers "why is this more than the quote?" before anyone asks it.

How do you bill a copywriting retainer with overage?

Set the volume the monthly fee buys, the overage rate, and whether unused volume rolls over. Then show all three on every invoice.

Hypothetical example. An email retainer is $2,500 a month for up to 8 emails, with extra emails at $275 and no rollover. In May the client asks for 10:

Check: 2,500 + 2 × 275 = 3,050. If the client used only 6 emails, the invoice would still show "(6 used)", so the client sees the unused capacity and either uses it next month or agrees a lower tier. See the retainer agreement guide for retainer terms more generally.

Who owns the copy after the client pays?

In the US, not automatically the client. A commissioned work is a "work made for hire", owned by the client from the start, only if it falls into one of nine categories in the Copyright Act and both parties sign a written agreement saying it is a work made for hire. The nine categories are a contribution to a collective work, part of a motion picture or other audiovisual work, a translation, a supplementary work, a compilation, an instructional text, a test, answer material for a test, and an atlas (US Copyright Office, Circular 30: Works Made for Hire, revised August 2024). A typical website page, sales email or ad usually does not fit any of them neatly. Where the work is not made for hire, the freelancer owns the copyright. A transfer of ownership is valid only in a writing signed by the owner of the rights (17 U.S.C. § 204(a)).

What this means for the invoice:

• The contract does the legal work: a signed assignment of copyright (often effective on full payment), or a licence that sets the media, territory and period.
• The invoice repeats it in one line so finance and the next marketing manager can find it: "Copyright in the final copy assigned to the client on full payment, per agreement dated 3 March" or "Licensed for paid social in the US for 12 months from 1 April; renewal on request".
• If the licence is for a period, a renewal is a new line on a new invoice when the period ends.

This is general information about US law, not legal advice. Other countries have different rules, and an ownership clause is worth a lawyer's review for large projects. Last reviewed: 27 October 2026.

Can you invoice copywriting work in InvoiceQuickly?

Yes. Here is how each pattern above maps to what the app does today.

Available now:

• Line items with quantity × unit price (up to 100 lines), with descriptions up to 1,000 characters and notes and terms up to 5,000 characters each, all printed on the PDF. Your ownership or licence sentence fits in a line description or in Terms.
• Type or say what you delivered and an AI draft fills the client, lines and terms into the editor for you to review before saving. Free includes 3 AI drafts; Pro ($9/month) is unlimited. The Free plan also includes 5 invoices and 5 clients.
• One discount percentage and one tax percentage per invoice.
• Invoices in USD, EUR, GBP, CAD, AUD, INR or PKR, chosen per invoice.
• Recording full or partial payments on every plan.
• On Pro: estimates the client accepts in their portal and converts to an invoice, email delivery, scheduled reminders, Stripe or PayPal payment links through your own account, and CSV export.

How to enter the patterns:

• 50/50 projects: send two invoices, each with one line, and put the project total and the earlier invoice number in the line description, as in the example. There is no deposit feature, and line amounts cannot be negative.
• Retainers on Pro: a recurring schedule creates one line each month with saved payment terms (30 days by default) and the saved tax and discount rates, either as a draft or sent automatically. For retainers with overage, keep the schedule on drafts and add the overage line before you send.
• PO numbers: there is no PO field. Put the PO number at the start of the first line or in the notes.
• Per-word fees: quantity × rate works for whole-cent rates. For fractional-cent rates, see the note on rounding in the writers and authors guide.

On Pro, track hourly research with a timer or manual time entries, then select the unbilled entries for a draft invoice you review. Contracts, e-signatures, invoice attachments and a dedicated PO field are not included.

When is this setup not the right fit?

• Your clients require approved timesheets before billing. Pro records time, but it does not provide a client timesheet-approval workflow. Follow the client's approval process before invoicing those hours.
• Your clients require invoices through their own supplier portal, such as a large company's procurement system. You submit the invoice there, so a separate invoicing tool adds a step.
• You are writing through an agency or marketplace that bills the end client for you. You invoice the agency or nobody, depending on the platform's rules.

Frequently asked questions

Should a copywriter charge per word or per project?

For commercial copy, a fixed fee per deliverable is common because a 200-word headline section can take longer than an 800-word article. Per-word pricing suits long-form content where length tracks effort. Whichever you choose, the invoice should repeat the same unit the client agreed to.

How do I bill extra revision rounds?

Put the rounds included in the agreement, then bill each extra round as its own line with the deliverable and the date the client requested it, for example "Extra revision round, homepage (third round, requested 21 March): $250". Do not fold it into the page fee.

Do I need to put usage rights on the invoice?

The agreement is what grants or transfers rights. In the US, a transfer of copyright needs a writing signed by the owner. Repeating the terms on the invoice in one sentence, with the agreement date, keeps the fee and the rights together for the client's records.

When should a copywriter send the invoice?

For projects, at the milestones in the agreement, such as signing and final approval. For retainers, on the same date each month. For agencies, as soon as the copy is approved, with their PO number and on their payment terms, such as Net 30, so it can go into the agency's next payment run.

Do copywriters charge sales tax?

It depends on where you and the client are and what you deliver. Sales tax rules for services and digital products vary by state. Check your state revenue department before adding a tax line.
