Why plumbing professionals should send beautiful invoices

Illustration of invoice being sent

You’ve never met a drain you couldn’t unplug – and you know no two plumbing contract jobs are ever the same. You need an invoice that is flexible enough to clearly detail your labor, as well as all the associated costs for the job.

Plumbing is a specialized skill, so your customers may not realize all the knowledge and expertise you bring into their homes. That means your invoice also needs to be easy-to-understand so your customers know exactly what they are paying for.

Besides technical know-how, you also supply great customer service, especially in stressful plumbing emergencies. Make sure your invoice is as polished and professional as the work you provide, and adds to your outstanding reputation.

How to fill out your plumbing invoice

Once you've downloaded your free invoice template, you'll need to customize it to fit your specific business. Here are the 10 key things to include on your invoice:

  1. Title and Description: Name the project and briefly describe what type of work your client is being invoiced for.
  2. Company Details: Add your company name, address, phone number, and logo to the top-right corner.
  3. Customer Details: Under "Bill To", add your customer's name, address, and contact information.
  4. Invoice Number: Include a unique invoice number to help you track down this invoice in the future. You can format this based on sequence and customer. For example, if you're sending your very first customer their first invoice,  the invoice number could be 001-001.
  5. Dates: Include the date when your invoice has been issued and the date when payment is due.
  6. Line Item: Add individual line items for each unique good or service you provided. For each line item, include a brief description, quantity, individual unit price, and total price.
  7. Subtotal: Add up the subtotal of your goods or services, before tax has been applied.
  8. Tax: Indicate the tax rate applied to the subtotal. This is legally required to provide on invoices, and your rate may differ depending on where you run your business.
  9. Total: Outline the total amount due from the customer, after tax.
  10. Notes: Include any additional info your customer should know, including terms of service and payment terms (for example, payments are due 30 days after the invoice has been issued).

When is the right time to send an invoice to your plumbing customers?

As a professional plumber, you do both big and small jobs – so the right time to send an invoice depends on the size of the job and your relationship with the customer.

For small jobs, most plumbers invoice upon completion, but if it’s a big job requiring special plumbing parts and materials, as well as many hours of labor, many plumbers ask for a percentage of the cost up front, with the remainder when the job is finished.

If you are on retainer, or provide ongoing plumbing services to a corporate or municipal client, invoice at regular intervals to keep the revenue coming in.
