How to use an invoice template
Everything you need to invoice a client
An invoice is a formal request for payment. It tells your client what they bought, what it cost, and how and when to pay. A good template takes care of the layout so you only have to fill in the details.
What every invoice should include
Our templates already have a place for each of these, but it helps to know why they matter. Missing any of them is the most common reason an invoice gets queried or paid late.
- The word "Invoice" at the top, so it is not mistaken for a quote or receipt.
- A unique invoice number. Sequential numbers (INV-0001, INV-0002) make bookkeeping and tax time far easier.
- Your business name and contact details, including your address, email, and phone number.
- Your client's name and address. If they are a company, address it to the person who approves payment.
- The invoice date and the due date. "Net 30" means payment is due 30 days after the invoice date. Be explicit.
- Line items with a description, quantity, unit price, and line total for each product or service.
- Subtotal, tax, and total due. Show tax on its own line if you charge it, and note your tax registration number where required.
- Payment instructions. Bank details, an online payment link, or the cheque payee name.
- Terms and notes, such as late-payment fees, early-payment discounts, or a simple thank-you.
Which format should you choose?
All of our templates contain the same core fields, so the choice comes down to the software you use and how you plan to send the invoice.
| Format | Best for | Keep in mind |
|---|---|---|
| Word (.docx) | Service businesses that want full control over wording and layout. | Totals are typed by hand, so double-check your math. |
| Excel (.xlsx) | Anyone billing multiple line items or charging tax. | Formulas calculate totals for you. Export to PDF before sending. |
| Google Docs / Sheets | Working from a browser or sharing with a bookkeeper. | Click the link, choose "Make a copy", and it saves to your Drive. |
| Printing, or sending a file the client cannot edit. | Fill in with a PDF editor or print and write by hand. | |
| Open Office (.odt) | OpenOffice and LibreOffice users. | Also opens in Word and Google Docs. |
Step by step: from template to paid invoice
- Download the template in the format you prefer, or open the Google version and make a copy.
- Add your branding. Replace the placeholder logo and type your business name and contact details into the header. Save this version as your master copy.
- Fill in the client and dates. Enter the client's details, today's date, a due date, and the next number in your sequence.
- List what you are charging for. One line per product or service. Be specific: "Website redesign, 12 hours at $85/hr" is clearer than "Design work".
- Check the totals and tax. In Excel and Sheets this happens automatically. In Word and PDF, add it up carefully.
- Save as PDF and send. A PDF keeps the formatting intact on any device. Attach it to a short email that restates the amount and due date.
- Record it. Note the invoice number, amount, and date sent so you can follow up if it is not paid on time.
Tips for getting paid faster
- Send the invoice as soon as the work is done. Every day you wait is a day added to the payment cycle.
- Keep payment terms short and clear. "Due within 14 days" is easier to act on than "Net 14".
- Offer more than one way to pay, and put the instructions on the invoice itself.
- Follow up politely the day after the due date. Most late payments are forgotten, not refused.
- If you invoice regularly, consider an invoicing tool that tracks payments and sends reminders automatically.

Yes. Every template on this site is free to download and use for your business, with no account, watermark, or trial period.
Can I edit the templates?
All of them. The Word, Excel, and Open Office files open in their respective programs, the Google versions copy into your own Drive, and the PDF can be filled in with any PDF editor.
What is the difference between an invoice and a receipt?
An invoice asks for payment and is sent before the client pays. A receipt confirms that payment was received and is sent afterwards.

Use Excel or Google Sheets if you want totals and tax calculated automatically. Use Word or Google Docs if your invoices are mostly text. Use PDF when you need a fixed, printable document.
