How many times have you been chasing up overdue invoices in the past few months? Are your accounts team scrambling through spreadsheets and paper documents every month to determine which customers are up to date with their payments? In order for your plumbing business to remain profitable, you’ve got to have a solid invoicing process and be estimating strategically.

Plumbing invoicing is no different from many other field services; your field team scopes out the work for a customer, an estimate is drawn up with a date decided upon with the customer on when to carry out work. Once the work is complete, an invoice is issued to the customer so they can provide payment. If that process isn’t smooth sailing, you’ll start to encounter cash flow problems, and it will affect your bottom line.

Understanding Plumbing Invoicing

So how can you make sure you’re not harming your business with a poor plumbing invoicing strategy? An invoice is an important document within any business.

Whether you’re using a plumbing invoicing template or you’re working from scratch, an invoice needs to be clear, precise and easy to understand.

There are key elements to an invoice you want to ensure you’re not skipping over. You always want to include an itemized parts and labor list, the customer's address and your business information (including relevant business registration and tax requirements), an invoice number, final costs and available payment methods.

Frequently Asked Questions

Whether you’re just starting your own plumbing business or you’re a seasoned professional. There are always going to be questions on your mind when it comes to plumbing invoicing. Let’s take a look at some frequently asked questions within the industry.

What information should be included in a plumbing invoice?

If you think about all of the information your customers need to know in order to pay their invoice, that’s what you’ll want to include on your invoice. This means things such as:

  • Your plumbing company contact information, including email address and phone numbers
  • Any required business registration or taxation information
  • An itemized list of materials and labor
  • Street address of where the work was done
  • Invoice date
  • The date the work order was completed
  • The total amount due
  • The payment methods available
  • Due date for payment
  • Payment and billing terms

How often should I invoice my clients?

It’s most common in business to send invoices on a monthly basis. However, within the plumbing industry, it works a little differently. If you’re doing residential work, then it’s likely an invoice will be issued once the work has been completed, depending on the project size.

If you’re completing commercial work, it may be a project that’s split into different stages. In which case, you may invoice after stage one is complete. It’s also easier to track payments for larger commercial projects if you collect in stages.


How can I track my invoices and payments?

With a comprehensive plumbing invoicing software package, you can track invoices and payments simultaneously. Rather than relying on paper spreadsheets and rummaging through paper documents, it helps streamline your processes and provides further visibility into how your jobs are progressing. You can run and schedule reports around your invoicing and payments, giving you further insight into what’s outstanding and what’s paid.

Is it important to provide itemized invoices?

Yes. It shows the customer what they’re paying for as well as the materials used for the work. It builds trust between you and your customer, as there’s no smoke and mirrors between the estimation and the final costs.


Once you’ve nailed down your plumbing estimating and invoicing process, you can be safe in the knowledge that you’re bringing in revenue to your business. In addition to that, you want to be charging a reasonable amount for the services you’re providing.
