1. What every physical therapist invoice must include
A compliant physical therapist invoice has eight parts: your business name and contact info, a unique invoice number, issue date, payment due date, the customer's name and address, an itemized list of work, the total amount due, and accepted payment methods. If you're collecting sales tax, that line is required too.
2. Set your line items
Most physical therapists structure invoices around these 4 categories:
- Initial evaluation — billed by flat at a ~$220 default.
- Treatment session — billed by session at a ~$145 default.
- Insurance billing — billed by flat.
- Self-pay package — billed by flat.
3. Set payment terms
The standard for physical therapists is Net 30 — payment due within 30 days of the invoice date.0 Spell out late-fee terms (most states cap monthly late fees around 1.5%) and accepted payment methods on the invoice itself.
4. Licensing & legal disclosures
State PT license required. Direct-access laws vary by state. HIPAA-compliant invoicing required for insurance billing.
5. Send and follow up
Send the invoice the same day work is completed (or upon milestone for larger projects). Use software that tracks opens and lets the customer pay by card or bank transfer in one click — the average physical therapist-class invoice gets paid 2× faster when the customer can pay online without leaving their inbox.
