What to include in a translation invoice
- Language pair. Source and target languages, such as Spanish into English, because agencies and clients reconcile invoices by language pair and job.
- Word count and basis. The number of words and whether it was counted on the source or the target text, so the client can run the same count and match your total.
- Rate per word or 1,000. The unit rate as quoted, per word or per 1,000 words, shown next to the count rather than only as a total.
- Certified translation noted. Which documents carry your signed statement of accuracy, since the certificate is part of what the client bought and is often filed with the translation.
- Minimum fee. The smallest fee you accept for a job, shown as its own line when it applies, so a one-page birth certificate is not billed at the word rate.
- Repetitions and matches. If you discount repeated segments or translation memory matches, the match bands and the rate for each, so the weighted word count is clear.
- Rush or specialist surcharge. Any extra for weekend turnaround or legal, medical or technical content, on a separate line so the base rate stays the one you quoted.
- Agency PO or job number. The agency's job number or PO and the document name, since agencies pay against their own reference and hold invoices without it.
