Freelance writer invoice template: per word, per piece or per hour

Freelance writing is one of the few trades where the same invoice has to flex across three completely different pricing models, sometimes for the same client in the same month. A per-word blog post, a flat-fee case study and an hourly editing job all need to show up on paper in a way the person approving payment can check at a glance. Get the line items right once and every invoice after that is just filling in numbers.

The base every freelance writer invoice needs

Whatever you're billing for, start from the same core fields:

1. The word "Invoice", a unique sequential number (INV-0001, INV-0002…) and the date you're sending it.
2. Your name or business name, with contact details a client's accounts team can actually use.
3. The client's name and who the invoice should go to — the editor who commissioned the piece often isn't the person who pays.
4. What was written, specific enough that someone who never read the piece knows what they're paying for: "Blog post — '10 Tips for Remote Teams,' 1,200 words" beats "Writing services."
5. A subtotal, tax if it applies, and the total due.
6. A clear due date — "Due 13 November 2026," not "net 14" left for the client to calculate.
7. How to pay, with a reference so your payment is easy to match against the invoice.

From there, the one line that changes shape is how you've priced the work.

Per word: show the rate and the count

Per-word billing is the most common setup for articles, blog posts and copywriting, and it's also the one clients query most if the maths isn't visible:

• State the word count, the rate and the total on one line: "Article — 'Choosing a CRM,' 1,500 words @ $0.35/word — $525." Never just show the total.
• Use the final word count, not the brief's target, if the piece ran long or short. If you agreed a minimum fee regardless of length, say so on the invoice rather than leaving the client to do the subtraction.
• Bill research or interviews separately if they weren't part of the per-word rate — a short note like "Includes 1 scheduled interview" keeps the scope visible.

Per piece: name the deliverable, not just the fee

Flat-fee work (a case study, a newsletter issue, a set of product descriptions) is simplest to invoice, but only if the deliverable is named clearly:

• One line per deliverable, with a short description: "Case study — Acme Co. customer story — $650," not "Writing project — $650."
• List revision rounds included, if your quote specified a number, so there's no ambiguity about what the fee covers versus what's extra.
• Add a kill fee line if the piece was cancelled or shelved after you'd started. A common rule of thumb is 50% of the agreed fee for work cancelled after a first draft, but that's something to set in your contract or quote up front, not decide at invoice time.

Hourly: for editing, consulting or ongoing work

Hourly billing suits editing, content strategy or anything that doesn't reduce neatly to a word count:

• One line per task, with hours and rate shown: "Developmental edit — 4 hrs @ $90/hr — $360," so the client can see where the time went rather than just a lump sum.
• Attach a short time log for anything beyond a couple of hours — date, task, duration. It turns the invoice into something checkable instead of something to trust blindly, and it's usually the fastest way to get an hourly invoice approved without back-and-forth.
• Round consistently (to the nearest quarter hour is common) and mention it once rather than varying invoice to invoice.

Our guide on invoicing for hourly work goes further into tracking the hours themselves.

Usage rights and reprints: say what's included

Writing invoices carry one wrinkle most other freelance invoices don't: what the client is actually allowed to do with the piece. If your rate covers first publication only, and a reprint, syndication or ongoing usage would cost extra, note that on the invoice itself — "Fee covers first online publication; additional usage billed separately" — rather than assuming it's understood. It's a small line that avoids an awkward conversation months later when the piece turns up somewhere else.

Deposits and kill fees for bigger commissions

For a larger commission — a long-form feature, a multi-part series, a ghostwritten report — it's reasonable to ask for a deposit before you start, with the balance due on delivery. Our piece on asking for a deposit before starting work covers how to word that without it feeling awkward to raise. Whatever you agree, the invoice should match the contract exactly: deposit amount, balance, and what happens (kill fee, partial payment) if the piece is cancelled partway through.

Tax on a freelance writer invoice

Whether you need to show tax on your invoices — and at what rate — depends entirely on where you're based and whether you're registered. In New Zealand or Australia that generally means GST once you're over the registration threshold; in the UK it's VAT; in the US, freelance writers are usually self-employed for tax purposes with no sales tax line at all on most services. If you're not sure which applies to you, a quick check with your accountant is worth more than guessing from a template.

Keep one template, swap the line items

The invoice itself barely needs to change between a per-word article, a flat-fee case study and an hourly edit — only the line-item pattern does. InvoiceCharlie handles that for you: itemised lines for per-word and hourly work, flat-fee line items for fixed-price pieces, and sequential numbering so you never have to think about what invoice number comes next. If you just need one invoice out the door right now, the free invoice generator will have a proper one ready in a couple of minutes, no account required.
