How to use this Medical Invoice template
- 1Replace the sender block with your own name, address and tax number.
- 2Add the client's legal name and billing address exactly as they gave it.
- 3Set a sequential invoice number and an explicit due date, not just "Net 30".

- 5Export to PDF and attach it to a short email naming the invoice number.
Medical Invoice: mistakes to avoid
- Never reuse an invoice number. Cancel and issue a credit note instead.
- Write the due date as a real date. "Net 30" invites an argument about day one.
- Include the purchase order number if your client uses one — some finance systems will not pay without it.
- Send PDF, not Word, so the layout cannot shift on the client's machine.
Frequently asked questions
Is this Medical Invoice template really free?
Yes. You can fill it in, export it to PDF or Word, and send it to a client without creating an account, and the exported file carries no watermark or branding of ours.
What must a Medical Invoice include to be valid?
A unique sequential number, the issue date, an explicit due date, both parties' names and addresses, an itemised breakdown of what you delivered, the subtotal, any tax shown separately, the total due, and how to pay you. Most tax authorities also require your registration number where you have one.
Can I edit the line items and tax rate?
Yes. Add or remove rows, change descriptions and rates, and set your own tax percentage. The subtotal, tax and total recalculate from the rows, so the arithmetic on the page always adds up.
PDF or Word — which should I send?
Send the PDF. It renders identically everywhere and cannot be altered by accident. Keep the Word file for the occasional client whose finance system asks for an editable copy.
