IT SERVICES INVOICE TEMPLATE
Free IT services invoice template
An IT services invoice built for business clients: the managed plan by workstation and server, project labor by task and hour, hardware and licenses resold on their own lines, and the PO number, due date and tax ID a client's accounts team looks for. Free in Word and PDF, with every line explained.
Word and PDF · Free · No email, no sign-up
The short answer
An IT services invoice bills the monthly plan — devices × rate, with what's covered — then any project work by task with the hours and the date, then hardware and licenses resold on their own lines, so the client sees the fixed cost, the one-off work and the pass-through costs apart.
The lines that get it paid are the ones a client's accounts team looks for: their purchase order number, your legal business name and EIN exactly as on your W-9, the period covered, a due date (net 30 is the norm), and descriptions a manager can approve without asking what you did.
Finish with how to pay — ACH details save the most time — and a note on anything that changes next month's plan, such as a device added mid-month.

LINE BY LINE
What goes on an IT services invoice
Every line on the template, in order, and what to write on it.
| The line | What to put there |
|---|---|
| Legal business name, contact and EIN | Your legal name and EIN exactly as on your W-9, with your phone, email and address. A business client's accounts team matches the invoice to the W-9; a mismatch is the commonest reason an IT invoice stalls. |
| Invoice number, dates and PO number | A number that never repeats, the invoice date, the due date (net 30 is the norm) and the client's purchase order number if they issued one — many companies can't pay without it. |
| Bill to and the engagement | The company with its accounts-payable contact or email, then the engagement: the plan with its device counts, the period and your day-to-day contact. |
| The managed plan by device | Workstations × rate on one line with what's covered — monitoring, patching, antivirus, help desk — and servers on another, with backup named. The client should be able to count the devices against the line. |
| Project labor by task | Each project or ticket outside the plan on its own line, with the date, the hours × rate or the fixed price, and what was delivered — written for the manager who approves it. |
| Hardware and licenses resold | Each item by model and serial, and each license by product and seat count, on their own lines. They're pass-through costs and, for hardware, taxable in most states — so they never sit inside a labor line. |
| Tax, total and balance due | Sales tax on hardware and, where your state taxes them, on software and services; the total; the balance due in bold. |
| How to pay and bank details | Net 30 or your due date, and how to pay — ACH details cut a week off payment. |
| Notes | Devices added or removed, anything that changes next month's plan — the line that stops the next invoice being a surprise. |
STEP BY STEP
How to fill out an IT services invoice
On the first business day of the month, from your monitoring console and ticket log.
Put your legal name and EIN at the top
Business name, contact details and EIN exactly as on your W-9, with “W-9 on file”. Save the file once with these filled in.
Number it, set the due date, add the PO
The next number in your series, today's date, net 30 as a date, and the client's PO number.
Name the client and the engagement
The company with its accounts-payable contact, the plan with device counts, the period, your contact, and any projects this period with dates.
Bill the plan, then project work, then hardware
Workstations and servers × rate with what's covered, each project by task with hours and date, and each piece of hardware or license resold on its own line.
Add tax and total it
Sales tax on hardware and, where your state taxes them, on software and services; then the balance due in bold.
Send it to accounts payable, PO in the subject
Email the PDF to the AP address with your contact copied, the PO and invoice numbers in the subject line, on the same day every month.
How IT businesses get paid faster
Bill the plan in advance, the work in arrears. The managed plan for October is invoiced on October 1; September's project hours ride on the same invoice. The client sees one predictable invoice a month, and your fixed revenue arrives before the month it pays for.
Get the PO before the engagement starts. Most companies above a certain size can't pay an invoice without a purchase order, and a standing PO for the year covers the monthly plan. Put the number on every invoice and in the subject line of the email.
Write each line for the person who approves it. “Project labor — install and configure Wi-Fi access point, second-floor operatory, Sep 23, 1.5 hours” gets approved by an office manager who never saw you. “Network work, 1.5 hrs” gets a question.
Match the W-9. In the US, a business client that pays you $2,000 or more in a year (the threshold for payments from 2026, up from $600; indexed from 2027) will ask for your W-9 and send you a Form 1099-NEC in January — put your business name and EIN on every invoice so their bookkeeper never has to chase you for it. The name and EIN on the invoice must match the W-9 you gave them, or the invoice sits in a vendor-setup queue.
Offer ACH and say so. Companies pay vendors by ACH on a schedule; a card or a check has to be requested separately. Bank details in the notes, with the invoice number to reference, cut a week off payment — and card on file is the right answer for the small clients who prefer it.
Keep hardware and licenses as pass-through lines. Resold hardware is taxable in most states and licenses are billed per seat; buried in a labor line they're invisible, taxed wrong and unprovable. On their own lines with model, serial and seat count, the client can match them to what arrived.
Tax depends on the state. In the US hardware and boxed or downloaded software you resell are taxable in nearly every state, and labor usually isn't — but several states tax computer, data-processing or repair services (Texas, Connecticut, Ohio and Hawaii among them), and cloud subscriptions are taxed in some states and not others. Keep hardware, licenses and labor on separate lines and check your state's revenue department or your accountant.
Outside the US. The invoice itself has rules: in Australia a GST-registered business issues a tax invoice showing its ABN, in New Zealand a GST-registered business shows its GST number, and in the UK and EU a VAT-registered business shows its VAT number and the VAT charged. Confirm the details with your accountant.
Send it from Zarla and get paid online
A Word template is a fine way to start. The catch is everything after you hit send: chasing the payment, remembering who's paid, and typing the same customer and the same line items again next month.
If you build your IT services website with Zarla, the invoice tool is in the same dashboard. Pick the customer, add the job's lines, and send it. On a paid plan, with your Stripe account connected, the invoice carries a pay-now button: your customer pays online by card, and the invoice marks itself paid when the money arrives. Customers you've invoiced are saved, so next time is two taps.

IT services invoices: common questions
Your legal business name, contact details and EIN as on your W-9; an invoice number, the invoice date, the due date and the client's PO number; the client with its accounts-payable contact; the engagement — the plan with device counts, the period, your contact; the managed plan as devices × rate with what's covered; project labor by task with hours and dates; hardware and licenses resold on their own lines; tax; the balance due; how to pay, with bank details; and notes on anything that changes next month's plan.
Per device is the commonest for small businesses — a monthly rate per workstation and a higher one per server, with what's covered spelled out. Per user suits companies where everyone has a laptop and a phone; a flat monthly fee suits a fixed, small office. Whichever you use, the invoice shows the count × rate so the client can check it against the headcount.
Net 30 — 30 days from the invoice date — is the norm for business clients in the US; net 15 for very small companies, and card on file charged on the invoice date for the smallest. Write the due date as a date on the invoice, not only as “net 30”, so the accounts team can see it.
As its own line on the monthly invoice: the ticket or project, the date, the hours × your out-of-plan rate or the fixed price, and what was delivered. Say on the plan quote what's outside it — new hardware setup, projects, after-hours — so the line never surprises anyone.
Each on its own line: hardware by item, model and serial at the price you quoted, licenses by product and seat count per month. Hardware is taxable in most US states; software and cloud subscriptions are taxed in some states and not others. Keep them out of the labor lines so the tax is right and the client can match the line to the delivery.
In the US a business client paying you $2,000 or more in a year — the threshold for payments from 2026, up from the old $600, and indexed from 2027 — will ask for your W-9 before the first payment and send a Form 1099-NEC in January. Give them the W-9 when the engagement starts and make sure the name and EIN on your invoices match it.
Yes. The IT services invoice template on this page downloads free as a Word document and a PDF — no email address, no sign-up. Edit it in Word or any app that opens Word documents, or print the PDF and fill it in by hand.
Not from a Word file — your customer still has to pay you some other way. To take the payment on the invoice itself, send it from invoicing software. If your IT services website is on Zarla, the invoice tool is in the same dashboard: on a paid plan, with Stripe connected, each invoice carries a pay-now button and marks itself paid when the customer pays by card.
Send invoices from your own IT website
Add your town and your business name, and Zarla builds the site from that one line — with invoicing in the same dashboard.
