Service-call fees and parts markup on a plumbing invoice
Most plumbers charge a service-call or call-out fee that covers travel and diagnosis, and it is often credited toward the repair if the customer proceeds. Show it as its own line and state the policy, for example "Service call fee $89, applied to repair cost if work is authorized today." Making the fee visible up front avoids the most common billing complaint, which is being charged just for a technician showing up.
Be transparent about parts markup. Plumbers routinely mark up parts to cover sourcing, stocking, and warranty handling, and customers accept it when it is not hidden. You can either show list prices that include a reasonable margin or note a flat markup percentage; what damages trust is a customer discovering a large undisclosed gap between your price and the store price.
Disclose emergency rates before the work, not on the invoice as a surprise. If after-hours, weekend, or holiday calls carry a premium, state it: "Emergency/after-hours labor billed at 1.5x standard rate." A customer who agreed to the rate on the phone rarely disputes it later, whereas one who first sees it on the bill often does.

Plumbing 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 Plumbing 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 Plumbing 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.
