How to Invoice a Company for Freelance Work (Guide)

How do you invoice a company for freelance work? Send a clear invoice that explains what work you completed, how much the company owes, and when payment is due. Freelancers may bill by the hour, project, or retainer, and may also need to handle deposits, partial payments, and international clients. This guide explains the key details to include and how to create an invoice that is easy for a company to approve and pay.

How to Invoice a Company for Freelance Work: Step by Step

1. Confirm the billing contact, the company's legal name, and whether a purchase order (PO) number is required.
2. Create an invoice with a unique invoice number, invoice date, and due date.
3. Describe the work clearly and show hours, units, or the agreed project fee.
4. Subtract any deposit already paid and show the remaining balance.
5. State the currency, payment terms, and how to pay.
6. Send the invoice as a PDF to the correct billing email.
7. Set a reminder to follow up if it is not paid by the due date.

What Is a Freelance Invoice?

A freelance invoice is a billing document that a freelancer sends to a client to request payment for completed work or an agreed project milestone. It usually includes the freelancer's details, client information, invoice number, services provided, amount due, payment terms, and payment instructions.

1. Choose How You Will Bill the Client

Freelancers commonly charge clients using a fixed project fee, hourly rate, or retainer. Your invoice should match the pricing arrangement you agreed to with the client. For hourly work, show the number of hours and hourly rate separately so the client can easily understand how the total was calculated.

2. Clearly Describe Your Freelance Work

Be specific when describing the work on your invoice. Instead of writing only "Design work — March," use a description such as "Homepage redesign, two rounds of revisions, delivered March 4–18." Clear descriptions help the client understand exactly what they are paying for and can reduce questions before payment.

3. Include Your Invoice Number and Date

Every freelance invoice should have a unique invoice number and invoice date. A simple numbering system such as INV-0001, INV-0002, and INV-0003 makes invoices easier to track. Read how to number invoices if you need help choosing a format.

4. Show Deposits and Partial Payments Clearly

If the client has already paid a deposit, show it clearly on the invoice and subtract it from the total amount due. For example, you might list a $300 deposit already paid as a separate line so the client can see the original amount, the payment already received, and the remaining balance.

5. Set Clear Freelance Payment Terms

State when payment is expected directly on the invoice. Depending on your agreement, you might use terms such as due on receipt, net 7, net 15, or net 30. Choose terms that match your client agreement and clearly communicate the payment deadline. It can also help to establish payment terms in your original project agreement before work begins. Compare the options in invoice payment terms explained.

6. Clearly State the Currency

If you work with clients in different countries, clearly state the currency on your invoice. For example, specify USD, EUR, GBP, CAD, or another currency rather than writing only a number such as "$500." Clear currency information helps prevent confusion about the amount the client is expected to pay.

7. Include Payment Instructions

Tell the client how they can pay the invoice. Depending on your business and agreement, this could include bank transfer details, a payment link, PayPal, card payment instructions, or another accepted payment method. Make the payment instructions easy to find so the client does not have to contact you for basic payment information.

8. Include Your Contact Information

Add your name or business name, email address, and other relevant contact information. The client should know who issued the invoice and how to contact you if they have a question about the work, amount, or payment.

When the Client Is a Company

Companies often have an accounts-payable process. Use the company's legal name, send the invoice to the billing contact, and include a purchase order number if they gave you one. Some companies also pay only on set cycles, so check their payment schedule early. More tips are in our guide to invoicing a small business client.

How to Handle Late Freelance Payments

If the payment due date passes without payment, send a short and professional follow-up. Reference the invoice number and original due date rather than sending a vague reminder. For example: "Just checking in — invoice INV-0032 was due on the 14th. Please let me know if you need anything from me to process it." More examples are in invoice email templates.
