The benefits of using a professional trade business invoice
Your plumber invoice isn’t just important for billing customers correctly. It’s an important business document. You’ll need it for preparing your accounts and making sure you pay the right amount of tax.
Here are some of the ways a professional plumber invoice can help boost your trade business:
Let your professionalism shine through
Your invoice is probably one of the few documents customers receive from you. So, you’ll want it to look as good as possible.
An invoice template shows you are:
Professional
Well-organised
Keen to charge your customers correctly
Expecting to be paid on time
Improve your cash flow
If your invoicing is up to date and accurate, then your cash flow forecasting should be too. Improving cash flow is a challenge for most trade businesses.
Your invoices record your income, against which you deduct business expenses to work out your cash flow.
How to improve cash flow for trade businesses
What keeps tradespeople awake at night? Worrying about getting paid on time and settling your bills is probably a contender. Often, it all comes down to cash flow. Poor cash flow can quickly bring down even a successful business. Keep in control It doesn't matter whether you're a small or large
Charge business expenses to customers
It’s not just your labour costs that can go on invoices. Plumbers usually have to buy materials for jobs.
You’ll probably want to charge some or all these costs to customers. Often, plumbers will mark up the cost of materials. This allows you to earn more profit on jobs.
In addition, you might want to spread the cost of maintaining your plumber tools and equipment over several jobs. The same goes for professional costs like plumber insurance.
Include costs you want to charge to customers in your invoice.
Keep accurate business records
Use an invoice template to automatically generate high-quality business paperwork. It helps you keep on track.
Your accountant (if you use one) will welcome having accurate invoices to prepare your business accounts. That could help to reduce their bill to you for preparing your accounts.
You’ll need income and expense information on your tax returns to HMRC. Using a free template gives you greater peace of mind about the information you submit.
If you don’t keep adequate records, you could face a £3,000 HMRC fine.

Make sure your plumber invoices get paid
As part of your invoicing, there’s wording you can include to help things run smoother. These will often be referred to as terms & conditions – or "Ts & Cs".
When you want customers to pay you
Terms and conditions tell customers how you work. They help customers understand what you will – and won’t – be doing. Put your payment terms in writing on your invoice.
Options include payment in advance, or when the job is finished, or 30 days from the invoice date. Doing this helps you avoid misunderstandings later on or late payments.
How you want customers to pay
If you're using a free invoice template, then online payments could make sense. You'll probably find that nowadays more customers are comfortable making digital payments.
Taking card payments should make it easier to match money coming in against your invoices.
What happens if customers don't pay
With good customer relationships, you'll hopefully rarely be in the awkward position of having to chase up invoice payments.
But business life isn’t always simple. You may need to chase overdue invoices. Remember, you have certain rights as a tradesperson for getting paid.
Accurate invoices can help if you take legal action against customers or use debt collectors. Your invoices should provide key evidence of what customers owe you.
