How to make a plumbing invoice
- Add your business details. Enter your business name, address, phone, and email, and add your logo. Include your plumbing license number where required.
- Enter the client and job. Add who you're billing and a short job or project reference.
- List your line items. Break out labor (service call, hours, or flat rate) and materials or parts, each with a quantity and price. Itemizing parts separately from labor reduces disputes.
- Add tax, discount, and notes. Apply your tax rate, any discount, and your payment terms — due date and accepted payment methods.
- Download the PDF. Tap Download PDF and send it to your client by text or email. The invoice never leaves your device.
What to include on a plumbing invoice
Every plumbing invoice should include your license number (required in most states), a description of the work performed, parts and materials with costs, labor hours and rate, travel or trip charges if applicable, and your payment terms. Itemizing parts separately from labor makes the bill easy to understand and reduces disputes.
