How to Invoice as a Translator: Rates, Terms and Templates

To invoice as a translator, issue one invoice per job (or per month for an agency that allows it) that shows the language pair, what was translated, the quantity and how it was counted (source words, pages or hours), your rate, any surcharges as their own lines, the PO or project reference, the currency, and the payment terms. Agencies and direct clients need slightly different invoices, and the differences are where most payment delays start.

This guide covers the billing models translators use, what each invoice line should say, how to invoice an agency compared with a direct client, a worked invoice with the arithmetic, and the US tax paperwork clients will ask for. If you bill agencies through a CAT-tool fuzzy-match grid, minimum fees or certified translations, or invoice business clients in other EU or UK countries, our invoicing for translators page works through those cases, including the reverse-charge wording.

How do translators charge: per word, per page or per hour?

Source-word billing is the default for a practical reason: you and the client can both count the words before the job starts, so the quote and the invoice match. Target-word billing works too, but say on the quote that the final total depends on the translated length.

One InvoiceQuickly-specific point: line prices are stored to the cent. A per-word rate of $0.14 is fine, but a rate like $0.125 is rejected because unit prices accept at most two decimals. Enter the word count as the quantity at a two-decimal rate, or bill the line as one item with the computed total and put the count and rate in the description. The translators page shows how this affects fuzzy-match bands.

For setting the rates themselves, see how to price translation services. As context for an hourly equivalent: the US Bureau of Labor Statistics puts the median pay of employed interpreters and translators at $60,170 a year, or $28.93 an hour, in May 2025, and notes that about 28% of the occupation is self-employed and excluded from those wage figures (BLS Occupational Outlook Handbook, page updated August 27, 2026). A freelance rate has to cover the unpaid time, software and benefits an employer would otherwise pay for, so it is not directly comparable.

What should a translation invoice include?

Beyond the basics every invoice needs (your name and contact details, the client's details, an invoice number, issue date and due date; see what to include on an invoice), a translation invoice should show:

• Language pair on each line, written the same way the client writes it (EN>ES, EN to ES, or English into Spanish)
• What was translated: document name, file name or batch ID. If the project is confidential, use the client's job code instead of the document title.
• Quantity and basis: "8,400 source words (Trados analysis)", "3 pages", "2 hours"
• Service type: translation, MTPE, review, proofreading, DTP, certification
• Surcharges as their own lines: rush, weekend, formatting, specialist terminology
• The client's reference: PO number or project ID for agencies; quote number for direct clients
• Currency and payment details: the currency agreed in the quote, how to pay, and who pays transfer fees on international payments
• Terms: due date, late-payment terms you agreed, and any deposit already paid

The translation services invoice template lays these fields out as a downloadable reference page, and the how to write an invoice guide covers numbering.

How do you invoice a translation agency?

Agencies (language service providers) process vendor invoices in their own systems, so the invoice has to match their records exactly.

• Quote the PO or project number on every line. Agencies match your invoice to their purchase order. Without it, the invoice usually waits until someone works out which job it is.
• Use their word count. If the agency sent a CAT-tool analysis with the job, bill from that analysis, not your own recount. If you disagree with it, raise it before you deliver.
• Follow their invoicing schedule. Many agencies ask freelancers to invoice once a month for all jobs delivered that month and pay on terms such as net 30 from the invoice date or month end. Some require one invoice per PO. Check their vendor guidelines rather than guessing.
• One line per PO on a monthly invoice. A single monthly total makes any query hold up the whole payment.

Example monthly agency invoice (hypothetical rates):

If the agency's PO used a weighted word count from a fuzzy-match grid, bill the weighted count it shows; invoicing for translators explains how to lay out the bands.

How do you invoice a direct client?

Direct clients (companies, law firms, individuals) usually have no PO system and less experience buying translation, so the invoice has to explain more and carry more of the payment risk.

1. Send a quote first. State the source word count, the rate, the deadline, the surcharges and the payment terms. The invoice should then match the quote line for line.
2. Take a deposit on new clients and large jobs. A common pattern is part up front and the balance on delivery; agree the split in the quote.
3. Invoice on delivery, and say in the terms whether you release final files before or after the balance is paid.
4. Bill changes separately. New files, extra review rounds or source text that needed editing before it could be translated go on their own line, approved in writing first.

Worked example: a rush manual with DTP

A freelance translator quotes a US manufacturer for an English-to-Spanish user manual. The figures are illustrative, not market rates.

The quote asked for 50% up front: $837.60 paid before work started, leaving $837.60 due on delivery. No sales tax is shown in this illustration; whether translation is taxable depends on your state, so check with your state's revenue department.

There are two clean ways to show the deposit:

• One invoice, two payments. Issue the full $1,675.20 invoice at the start, record the $837.60 deposit as a partial payment, and the balance due on delivery is $837.60.
• Two invoices. A deposit invoice for $837.60 at the start and a final invoice for the full job that shows the deposit received and the balance. Use this if the client needs an invoice to release the deposit. See the deposit invoicing guide and handling partial payments.

How should you invoice international clients?

• Fix the currency in the quote and invoice in that currency. Converting at the client's end creates small shortfalls that are hard to chase.
• Say who pays transfer fees. International bank transfers and payment platforms can deduct fees on the way, so state whether you expect to receive the full invoice amount.
• Sales tax and VAT depend on where you and the client are. For business clients in another EU country or outside the UK, there is usually no VAT on the invoice but specific wording is required; invoicing for translators covers the EU and UK rules from official sources. More general advice is in invoicing international clients.

What tax forms will US clients ask for?

US clients and agencies that pay independent contractors usually ask for tax details before the first payment:

• Form W-9 if you are a US person. It gives the payer your taxpayer identification number so they can file information returns with the IRS (IRS, About Form W-9, reviewed June 27, 2026).
• Form 1099-NEC. For tax years beginning after 2025, the payer reports nonemployee compensation of $2,000 or more in the year, up from $600 (IRS, Instructions for Forms 1099-MISC and 1099-NEC, revised 12/2026). Your income is taxable whether or not you receive a form.
• Form W-8BEN if you are not a US person and a US client pays you. You give it to the payer, not to the IRS, to document your foreign status and any treaty benefit (IRS, About Form W-8BEN, reviewed October 2, 2026).

Send the form once per client, not with every invoice. This is general information, not tax advice; check your situation with a tax adviser. Last reviewed: October 27, 2026.

Common translation invoicing mistakes

• Billing a different count from the quote. If you quoted on source words, invoice on source words, using the same tool or analysis.
• Hiding extras inside the translation line. Rush, DTP and review in one lump become the line the client disputes.
• Missing the PO number. For agencies, it is the most common reason an invoice is returned.
• Putting the confidential project name on the invoice. Use the client's job code if the project is under NDA.
• Leaving late-payment terms off until a payment is late. Agree any late fee in your terms before the work starts.

How to invoice translation work in InvoiceQuickly

Type or say the job ("Invoice Northfield Manufacturing, user manual v3 EN>ES, 8,400 words at $0.14, rush 20%, DTP 24 pages at $6, 2 hours at $60, 50% deposit received") and InvoiceQuickly drafts an editable invoice with the lines, rates and terms for you to check before saving. You can also build it by hand.

• Every plan: line items (quantity × unit price, up to 100 lines), one tax percentage and one discount percentage per invoice, notes and terms for the PO number, count basis and transfer-fee wording, PDF download, and recording full or partial payments, which is how you record a deposit.
• Currencies: USD, EUR, GBP, CAD, AUD, INR or PKR per invoice, with no automatic exchange-rate conversion.
• Pro ($9/month): estimates your client can accept in a private portal and then convert into an invoice, email delivery with the PDF attached, scheduled reminders before and after the due date, payment links from your own Stripe or PayPal account (their fees apply), credit notes if an agency disputes part of a job, and CSV export.
• Not available: there is no CAT-tool import or translation-job/deadline workflow; Pro does include timer/manual time entries and projects, with no separate deposit feature (use a partial payment or a second invoice). The PDF is in English with US number and date formats, and your tax ID is copied to new invoice PDFs; check the saved IDs and PDF before sending. The Free plan covers 5 invoices and 5 clients in total, so steady agency work needs Pro. See pricing.

When this guide is not the right fit

• Interpreting. Interpreting is billed by session, half day or day, with travel and cancellation terms that need their own structure.
• Agency owners invoicing end clients. If you resell other linguists' work, you need project and vendor management tools as well as invoicing.
• Sworn translators in civil-law countries. Fees for sworn or court translations can be set by local rules; check your appointing authority.

Frequently asked questions

Should I bill source words or target words?

Source words where you can. Both you and the client can count them before the job starts, so the invoice matches the quote. If you bill target words, say so on the quote and explain that the final total depends on the translated length.

How do I invoice a rush translation?

Add the rush surcharge as its own line, showing what it is calculated on and the deadline it bought, for example "Rush surcharge, delivery in 3 working days (20% of translation)". Agree the surcharge in the quote, not after delivery.

When should a freelance translator send an invoice?

For direct clients, on delivery (after a deposit at the start for new clients or large jobs). For agencies, follow their vendor guidelines; many ask for one invoice per month listing every PO delivered that month.

Do translators need to send a W-9?

US translators paid by US clients as independent contractors are usually asked for a Form W-9 so the client can file a Form 1099-NEC if they pay you $2,000 or more in a year (for tax years beginning after 2025). Translators outside the US give the payer a Form W-8BEN instead.

How do I show a deposit on a translation invoice?

Either record the deposit as a partial payment against the full invoice, so the balance due shows the remainder, or issue a separate deposit invoice and show it as received on the final invoice.
