Freelance and small-agency interpreters bill for spoken-language work in settings like medical appointments, courtrooms, depositions, conferences, business meetings, and remote video or phone sessions. Invoices usually go to a language services agency, a law firm, a hospital or clinic, a court, a school district, or a corporate client, and they cover time on assignment plus related charges such as travel and cancellations.

Most interpreters charge by the hour with a minimum booking, commonly two hours for in-person work and often one hour for remote work. Conference and simultaneous interpreting is usually priced by the half day or full day, because it requires preparation and a team of two. Rates rise for rare language pairs, certified or credentialed work (court, medical, ASL with certification), after-hours or rush bookings, and specialized subject matter. Many interpreters add portal time, travel time at a reduced hourly rate or flat fee, mileage, and parking. Late cancellation fees are standard, typically charging the minimum or a percentage of the booked time if the client cancels within 24 to 48 hours. Agency work often pays less than direct client work but brings steadier volume, and agencies set their own rate sheets and payment cycles. Translation of documents is a separate service priced per word or per page.

Notes: Payment due within 30 days of invoice date. Late balances accrue 1.5% interest per month. Cancellations with less than 48 hours' notice are billed at the 2-hour minimum. Please reference the case number on your payment.
Clients and agencies check billed time against their own records, and disputes usually come down to a 15-minute difference.
Agencies and courts often cannot process payment without a job ID, case number, or purchase order.
Rates differ by mode and language, so stating it justifies the rate on the line.
Certified work carries a higher rate and some clients need the credential on file for compliance.
Separating them shows what is time and what is reimbursement, and makes receipts easy to match.
Late cancellation fees are often questioned, so the booking terms and notice time should be clear.
Many agencies and government clients require a W-9 before paying, and a clear payee name avoids misdirected checks.
Direct clients such as law firms and businesses usually pay net 15 to net 30, and some interpreters require a deposit or prepayment for large conference bookings, often 25 to 50 percent. Agencies commonly pay net 30 to net 60 and may pay on a fixed monthly cycle, so check their terms before accepting work. Courts and government bodies often follow their own voucher or claim process and can take longer. Late fees of 1 to 1.5 percent per month are common if stated in advance. Typical payment methods are ACH, check, and card, and some interpreters add a small surcharge for card payments where allowed.
Put the two-hour minimum, travel rules, and cancellation window in your booking confirmation or contract. It is much easier to collect a cancellation fee that the client agreed to in writing.
Depositions, technical conferences, and medical specialties often require hours of glossary building and document review. List prep time as its own line so it is not treated as free.
Assignments often run over or start late. Note arrival time, start, and end in your calendar the same day so you can bill overage accurately and answer questions later.
Some agencies require you to submit through a portal, within a set number of days, or on their own form. Missing their window can delay payment by a full cycle.
Independent interpreters are typically self-employed and owe self-employment tax in addition to income tax. Many put aside 25 to 30 percent of each payment and make quarterly estimated payments, but check with a tax professional for your situation.
Yes. A one-hour appointment still takes travel, waiting, and a blocked-out window of your day. Two hours is a common in-person minimum, and one hour is common for remote work. State it on your rate sheet and invoice.
Yes, if you agree to it ahead of time. Many interpreters bill travel time at a reduced hourly rate or a flat fee, plus mileage at or near the IRS standard rate. Some agencies do not pay travel, so confirm before accepting.
Follow the cancellation policy you gave the client in advance. A common policy bills the full minimum, or a percentage of the booked time, if notice is under 24 to 48 hours. List it as its own line with the cancellation date.
Conference interpreters usually charge a half-day or full-day rate, since the work involves preparation and a team of two alternating. Quote the rate per interpreter and say what hours a day covers and what overtime costs.
It depends on the agency. Some pay from hours you submit in a portal, while others need a formal invoice with your name, address, and tax information. Ask for their process when you onboard.
