How to write a translator invoice

By James Carter, Small-business owner and InvoiceTools product lead

Translation is billed per word, which sounds simple until you decide whose words.

The free translator invoice template opens with these lines already in place.

The short version

To write a translation invoice, state the language pair, say whether the word count is source or target, show the count and the rate per word or per thousand words, bill proofreading and certification separately, quote the agency's PO, and state the currency.

What goes on a translator invoice

Six things, in the order they belong on the page. The invoice generator opens a translator document with the lines already in place, so most of this is checking rather than typing.

  1. State source or target word count. They are different numbers and the difference is real money. Name which one the rate applies to on the line itself.
  2. Show the language pair. English to German is not the same product as German to English, and a client with several pairs running needs to see which invoice is which.
  3. Bill proofreading and review separately. Revising someone else's translation is a different service at a different rate from translating from scratch. Do not fold it in.
  4. Name any minimum fee. A two hundred word job costs more to administer than it earns. If you have a minimum, it belongs on the invoice as a line, not as a surprise.
  5. Say whether the work is certified. Certified, sworn and notarized work carries a different rate and often a different deliverable. Put it on the document.
  6. Invoice in the currency you agreed. And say which one. An amount with no currency on a cross-border invoice is a payment waiting to be short.

The lines a translator invoice usually carries

The generator opens with these lines when you pick Translator. The figures are placeholders to type over, not a going rate.

LineWhat it coversQtyOpens at
Translation (per 1000 words)Translated by a person, not a machine, keeping the meaning and the tone of the original.6$110
Proofreading and reviewA second pass against the source text for accuracy, consistency and terminology.1$180
Certification of documentsA signed statement of accuracy where the document has to be presented officially.1$60

Add, rename, reorder or delete any line, and set tax per line where it applies. Priced as they open, that comes to $900 before tax.

How to write a translation invoice, step by step

  1. Put the language pair and the job reference first. Open the translator invoice and write the language pair and the client's job or PO number. An agency processing hundreds of jobs matches on that number.
  2. Enter the count and say whose words. 6,000 source words at a rate per thousand, with source or target stated. If repetitions were discounted, show the count and the discount on their own line.
  3. Add review as its own line. Proofreading and review are a second pass at a different rate. Priced at the translation rate, they are either undercharged or disputed.
  4. Add certification if it applied. A signed statement of accuracy for an official document is its own line, named as certified translation.
  5. State the currency, then send. Invoice in the currency agreed, say who pays bank charges on an international transfer, and set 30 days or the agency's terms.

Translation invoice example, filled in

A 6,000-word job for an agency abroad, with a proofreading pass and one certified document. The language pair, PO and word count basis sit at the top, because an agency pays nothing it cannot match to a job.

Subtotal $900, tax $90, total $990. Six thousand source words at $110 per thousand is the calculation, written so the agency's project manager can check it against their own count. The currency note decides who loses out to bank charges, which on a cross-border invoice is not trivial.

Source words or target words, and repetitions

The per-word rate is meaningless until the invoice says which words. A German translation of an English source will typically run longer, so billing on target words rather than source words changes the total on every job.

Pick one, agree it before you start, and print it on the invoice: "per 1000 source words" rather than "per 1000 words". If you discount repetitions or fuzzy matches from a translation memory, show the gross count, the discount and the net, because a client who cannot see the deduction cannot verify it.

A client who can check your arithmetic pays faster than one who has to trust it.

Certified, sworn and notarized work

This is a different product from a standard translation. It carries your statement, sometimes your seal, occasionally a notary, and it usually has to be delivered on paper.

Bill it as its own line naming what was certified, and put the certification fee separately from the translation fee. A client claiming the cost back, or submitting it to a court or an immigration office, needs the document to show clearly what was paid for.

Courier and hard copy costs belong on their own line too. Certified work is one of the few translation jobs with real physical costs attached.

Invoicing agencies, and invoicing abroad

Much translation work comes through agencies, often in another country, and they are process-driven payers. An invoice missing their PO number does not get queried, it gets ignored until you chase it.

Ask for the reference and the payment terms before you accept the job. Put both on the invoice. Set terms in days, since agencies work to a cycle, and if they use a self-billing arrangement, know that before you send an invoice that will never be paid because it was never supposed to exist.

For cross-border work, state the currency explicitly and agree who carries the transfer fees. The VAT calculator · GST Calculator covers the rate side where it applies, but which party bears the bank charges is a commercial agreement that belongs in writing.

Hourly, fixed price or per unit: how translators price the work

Translation is priced per word, and the two decisions that matter are whether the count is source or target, and what happens to repeated text. Get those wrong and the same job can be quoted at two prices that differ by a fifth.

ModelWhere it winsWhat it quietly costs you
Per source wordMost commercial work, because the client can see the count up frontLanguages expand and contract, so your rate has to account for the pair
Per target wordWhere the source is unclear, scanned, or not countableThe client cannot verify the figure until you have finished, which invites queries
Per hour or per projectEditing, proofreading, certification, transcreation, subtitlingIt hides the volume, so it needs a stated scope or a cap

Price revision, proofreading and certification as separate lines rather than as part of the word rate. They are different services with different risk, and certification in particular is a professional statement rather than a typing job.

Working out what to charge

Translation rates depend on the language pair, the subject and the client, so a per word figure from a web page is no guide. The freelance rate calculator works back from the income you need, and the billable hours calculator turns your daily word output into a realistic rate.

Getting paid once it is sent

Agencies pay on their own cycle, often 30 days or more after month end, so invoice each job as it is delivered with the PO on it; take a deposit from new direct clients on large projects. If the due date passes, the late fee calculator works out what your terms allow and the due date calculator sets the new date.

QuoteDepositInvoiceDue day 30Chase day 37
Quote: Always, stating source or target and the countDeposit: On large projects and new direct clientsInvoice: Sent the day the work finishesDue day 30: The date printed on the documentChase day 37: Reminder, then your late fee

Five dates decide whether a translator gets paid on time, and four of them are set before the work starts.

Mistakes that cost translators money

  • "Per word" without saying whose words. Source and target are different totals. Name the one you are billing.
  • Repetition discounts with no visible arithmetic. Show gross, discount and net or the client cannot verify it.
  • Proofreading billed at the translation rate. Different service, different rate. Separate them.
  • No currency stated on a cross-border invoice. An ambiguous amount gets paid at the payer's preferred reading.
  • No PO number for an agency. It does not get queried, it just sits unpaid until you chase it.

Translator invoice questions

How do I invoice as a translator?

Bill per word stating whether the count is source or target, show the language pair, keep proofreading on its own line, name any minimum fee, and state the currency. The generator opens a translator invoice with per word, proofreading and certification already listed.

Should I charge on source or target word count?

Either is standard, but the invoice must say which, because the totals differ. Source count is easier for a client to agree in advance since it is knowable before the work starts.

How do I show a repetition discount?

Show the gross count, the discount and the net on the invoice rather than only the final figure. A client who can check the arithmetic queries it less and pays sooner.

What should a certified translation invoice include?

The translation fee and the certification fee as separate lines, a description of what was certified, and any courier or hard copy costs on their own line, since the client may be submitting the document to a court or an official body.

Do I need a minimum fee?

Many translators set one, because a very short job costs more to administer than it earns. If you have one, put it on the invoice as a named line rather than letting it appear as an unexplained total.

How do I invoice a translation agency abroad?

Get their PO number and payment terms before accepting the job, put both on the invoice, set terms in days, and state the currency explicitly. Check whether they operate self-billing before sending an invoice at all.

Who pays the bank charges on an international payment?

Whoever you agreed, which is why it should be written down. State it on the invoice so the amount that arrives is the amount you billed.

What does a translation invoice look like?

Like the example on this page: your business and the client at the top, an invoice number, the issue date and a due date 30 days out, then translation (per 1000 words), proofreading and review and certification of documents as separate lines, each with a quantity, rate and amount. Below them sit the subtotal ($900), tax on its own line and the total due ($990), then the payment terms and a note on currency.

The paperwork is the part that gets you paid

A translation invoice goes to an accounts department, so the terms and the purchase order reference matter more than the wording. A due date beats a phrase, because their system matches on a date, and an invoice with no PO number is not refused, it is simply never approved.
