The different types of plumbing invoices 

Plumbers take on a variety of different jobs which may require different pricing methods. It is up to each individual business to determine the pricing and invoice method that works best for them. We have outlined some common invoice types for plumbing services below. 

Standard invoice

A standard invoice is the most common type of invoice. It lists exactly what the customer owes you for the provided goods or services. This can include any materials purchased, for instance, toilets, sinks, or bathtubs, and also the installation or maintenance fees. 

A standard invoice can either be a non-VAT invoice or a VAT invoice which we will explain below. 

Recurring invoice

A recurring invoice is used for ongoing services. The invoice is sent to the same customer at regular intervals, and each invoice will include the same products or services. Setting up recurring invoices with invoicing software will save you time by automatically creating and sending the invoice to your customer. 

Time-based invoice

Instead of charging a set fee for a specific job, time-based invoices charge for your services by time. Usually, the price is charged per hour you worked on the customers plumbing, but you can also charge a daily or weekly rate.

Prepayment invoice

A prepayment invoice is used when you require a deposit or downpayment from the customer prior to starting the work. Prepayments are common for large plumbing jobs or jobs that require you to purchase extra tools or materials that you wouldn’t normally use.

A prepayment invoice is an invoice that only includes the deposit/prepayment as an item line. You can find more information on invoicing with a deposit in our article: “Managing deposits with invoicing software”.

What needs to be on a plumbing invoice?

Invoices are a formal request for payment. Therefore, they require certain information to be valid under UK law. There are two forms of invoices, non-VAT invoices and VAT invoices. We will describe what each requires below. 

A non-VAT invoice is issued by non-VAT registered businesses to its customers. They require the name and address of both the seller and the buyer, an invoice number and issue date, a breakdown of the products or services being sold, and the total amount due. You can find a full list of mandatory information in our article: “What information needs to be on an invoice?”. 

VAT invoices are issued by VAT registered businesses to their customers. If you are VAT registered in the UK, you must apply value-added tax to your sales. VAT invoices include all of the same information found on a non-VAT invoice, but also additional VAT details like your VAT registration number (VRN). You can find a list of VAT invoice requirements in our article: “What are VAT invoices and who needs to issue them?”.
