Invoice template

What is an invoice, and when do you send one?

An invoice is a document you send to a client to request payment for goods or services you have provided. It itemizes what you did or sold, the price of each line item, the total owed, and the date payment is due. In accounting terms, an unpaid invoice is money in your accounts receivable, the cash your business is owed but has not yet collected.

You send one whenever you have finished work or delivered a product and it is time to be paid. Freelancers, independent contractors, consultants, and small business owners all rely on invoices to bill clients, stay organized, and get paid on time. A clear, professional invoice tends to be paid faster than a vague email asking for money, and it gives both sides a clean record for their books and their taxes.

Invoice vs. receipt vs. purchase order

These three documents are easy to mix up, but they mark different moments in a sale. Knowing which is which keeps your billing clean.

Document	Who sends it	When
Purchase order (PO)	The buyer	Before the work, to order goods or services
Invoice	The seller	After delivery, to request payment
Receipt	The seller	After payment, to confirm it was made

A proforma invoice is a preliminary estimate sent before the final invoice, and a commercial invoice is the version used for international shipping and customs. For a normal domestic sale, the standard invoice above is what you want.

The parts of an invoice

Every proper invoice contains the same core elements. The generator above lays them out for you, but here is what each one is and why it matters.

• Your details. Your business name and contact information, so the client knows who they are paying.
• The bill-to details. The client’s name and address.
• An invoice number. A unique reference for tracking and your records.
• Dates. The invoice date and, importantly, the due date.
• Line items. An itemized list of what you are charging for, with quantity, rate, and amount.
• Subtotal, discount, sales tax, and total. The math, added up clearly so there is no confusion about what is owed.
• Payment terms. When and how to pay, plus any notes such as late fees or a thank-you.

Types of invoice

The right invoice depends on how you charge, which is why the generator has a tab for each. Pick the one that fits your work before you fill it in.

• Standard. A general invoice with a quantity and a rate per item. Suits most businesses.
• Hourly. The quantity column becomes hours, ideal for time-based and freelance work.
• Freelance. A clean layout for creative and independent projects.
• Product. For selling goods, with quantities and unit prices.
• Service. For service calls, repairs, and labor plus parts.
• Consulting. For advisory work billed by the hour or by project.
• Contractor. For trades, with labor and materials on separate lines.
• Simple. A single line for a flat fee, when you want the least fuss.

For work you bill every month, the same template doubles as a recurring invoice: save the Word file and update the dates and invoice number each cycle.

How to make an invoice, step by step

With the generator above this takes just a couple of minutes. Choose your type, then:

1. Add your business name and details at the top.
2. Enter the bill-to details for your client.
3. Give it a unique invoice number, and set the invoice date and due date.
4. Add a line for each item, with its quantity and rate. The amount fills in automatically.
5. Set a sales tax rate or a discount if they apply. The subtotal and total update as you go.
6. Add a short note with your payment terms, then pick a design and color.
7. Download in Word or PDF, or copy the text, and send it to your client.

How to number your invoices

Every invoice should have its own unique number, and the numbers should follow a consistent pattern. This is how you and your client keep track of what has been billed and paid. The simplest system is sequential: INV-001, INV-002, INV-003, and so on. Some businesses add the year or a client code, such as 2026-014 or ACME-007, which makes filing easier at tax time.

The one rule that matters is to never repeat a number and never skip around randomly. A clean, sequential run of invoice numbers is what accountants and the IRS expect, and it saves you real headaches if you are ever asked to show your records.

Payment terms and getting paid faster

Payment terms tell the client when payment is due. The common ones are due on receipt, Net 15, and Net 30, meaning payment is expected immediately, within 15 days, or within 30 days. Shorter terms tend to be paid sooner, simply because they set the expectation. Whatever you choose, put the exact due date on the invoice rather than a vague “when you can.”

How you accept payment matters too. Spell out the options clearly, whether that is a bank ACH transfer, a card payment through Stripe or Square, or PayPal, Zelle, or Venmo for smaller jobs. The easier you make it to pay, the faster the money arrives. Being specific in your line items helps as well: “Consulting” invites questions, while “Strategy session, 6 hours” does not, and fewer questions means faster payment.

Do you need accounting software?

Not always. Full accounting tools like QuickBooks, FreshBooks, Xero, and Wave are worth it once you are sending invoices constantly, tracking expenses, and reconciling a business bank account. They automate reminders and keep your books in one place. But they also cost money and take time to set up, which is overkill if you just need to bill a client today.

For occasional invoices, a free template is faster than any of them. Plenty of people build invoices in Microsoft Excel or Google Sheets, but a spreadsheet has to be formatted from scratch and is easy to break. The generator above gives you a clean, professional invoice with the totals already calculated, ready to download as a Word document or PDF, with no sign-up and nothing to learn.

Invoices, sales tax, and 1099s

Whether you charge sales tax depends on your state, what you sell, and your registration status. The generator lets you add any tax rate and calculates it for you, but if you are unsure whether you must charge it, check your state’s rules or ask an accountant. This page is a template, not tax advice.

If you are an independent contractor in the United States, your clients may ask you to complete a Form W-9 so they can report what they pay you, and you may receive a Form 1099-NEC at year end. Your invoices are the records that should match those numbers, which is another reason to keep them numbered and saved.

Download in Word, PDF, or copy the text

The generator gives you three ways to send your invoice:

Tip: PDF is the standard for sending invoices, because it looks the same on every device and cannot be altered by accident.

Mistakes to avoid

• No invoice number. Without one, tracking payments and matching your records becomes a mess.
• No due date or payment terms. “Pay when you can” gets paid late. State a clear date and terms like Net 30.
• Vague line items. Unclear descriptions invite questions and delays. Be specific and itemized.
• Math errors. A wrong total looks careless and can cost you. The generator adds it up for you.
• Missing payment details. Make it obvious how to pay you, whether by ACH, card, or PayPal, or you will be chasing it.
