Free Nurse Practitioner Invoice Template (PDF & Excel)

1) Start with a clean header: include your name or clinic name, business address, phone, email, and logo if you use one. 2) Add identifying credentials: list your professional title, state license number and NPI (if you bill insurance or need professional ID). 3) Create a unique invoice number and add the invoice date. 4) Itemize services: for each line, include date of service, brief service description (avoid clinical details), units or duration, and the fee. If you bill using CPT or billing codes for private-pay arrangements, include them. 5) Calculate totals: subtotal, any taxes or fees (if applicable), discounts, and the final amount due. 6) Set payment terms and methods: specify due date (e.g., Net 15), accepted payment methods (card, ACH, check), and late fee policy. 7) Add notes: include a short note for the patient (receipt reference, appointment follow-up) while avoiding protected health information on the invoice itself.

Include: your full professional name and credentials, practice or business EIN (if applicable), NPI or license number, patient/client billing name, date(s) of service, service descriptions and codes, invoice number, invoice and due dates, accepted payment methods, and clear payment terms. Avoid: detailed clinical notes, diagnoses that reveal sensitive conditions, or PHI beyond a billing name or anonymized patient ID. For telehealth or contracted services, add the place of service, session length, and any cancellation/no-show fees. Keep copies for at least the period required by local regulations and provide receipts when payment is received.
