Contractor invoice template

What a contractor invoice needs

Whether you are an electrician, a builder, a general contractor or any independent tradesperson, an invoice does one job: it tells the client exactly what the work was, what it costs, and how to pay you. A clear invoice gets approved faster and gives you a proper record if a payment is ever queried.

Every contractor invoice should carry the same core details, so nothing is ambiguous when the client checks it against the job.

• Both parties — your business name and address, and the client's name and address.
• A unique, sequential invoice number so each invoice is easy to reference and track.
• The invoice date and, where relevant, the work or delivery date or period.
• A job or site reference — the address, purchase order or project name the work relates to.
• Itemised lines for labour and for materials, so the client can see how the total is built up.
• Net total, any tax, and the amount due.
• Payment terms — the due date, accepted methods and your bank or payment details.

Separating labour and materials

For trade work it is worth splitting the bill into two kinds of line. Show labour as hours or days multiplied by your rate, and list materials or parts as their own separate lines with quantities and prices. A client can see at a glance what they are paying for skilled time versus what they are paying for supplies.

This separation is not just tidier — it can matter for tax treatment in some places, since labour and goods are sometimes handled differently. It also makes variations easier: if a job runs long or needs extra parts, you add a line rather than reworking a single lump sum.

• Labour — e.g. “Electrical first fix, 12 hours × your rate”.
• Materials — e.g. “Cable, sockets and back boxes” as their own itemised line.
• Plant, hire or disposal — list separately if you are passing those costs on.

Deposits, progress billing and retainage

On larger jobs you rarely bill everything at the end. A staged approach protects your cash flow and shares the risk fairly with the client.

There are three common building blocks, and you can combine them to suit the job.

• Deposit — an upfront payment before work starts, often to cover initial materials. Show it as a line and deduct it from the final balance.
• Progress or milestone invoices — you bill in stages as agreed portions of the work are completed, rather than in one final invoice.
• Retainage or retention — where it is used, the client holds back a small percentage until the work is signed off, then releases it.

Tax on contractor invoices

Whether you add tax — VAT, GST, sales tax or the local equivalent — depends on your country and on whether you are registered. Many contractors below a registration threshold do not charge it at all; once registered, you usually add the applicable rate and show it clearly as its own line.

Construction work is a place where special rules sometimes apply. Some countries use a reverse charge for certain business-to-business construction services, where the customer accounts for the tax instead of you — that is only one example, and the details differ by country, so treat it as something to verify locally rather than a universal rule.

Getting paid

A clear invoice is also a faster-paid invoice. Make the due date unmistakable, state exactly how you accept payment, and set out any late fee up front so there are no surprises.

Keeping a numbered, consistent record of every invoice you send makes chasing a late payment straightforward — and makes your bookkeeping and any tax return far easier at year end.

• A specific due date, not just “on receipt”.
• Accepted payment methods and your bank or payment details.
• Any late-payment fee or interest, stated on the invoice.
• A unique invoice number so nothing is missed or duplicated.
