Free invoice generator, download yours now.

Creating a professional invoice takes less than two minutes with Billsato's free invoice generator. Here is how it works.

1. 1

   Enter your business details. Add your business name, address, email, and phone number. This appears at the top of every invoice you create, so your clients always know who the invoice is from. Upload your company logo too: it prints at the top, and its main color becomes the invoice theme.

2. 2

   Add your client's information. Fill in your customer's name, email, phone, and address. Accurate client details make sure the invoice reaches the right person and looks professional. If you ship somewhere else, tick “Ship to a different address” and add the delivery address.

3. 3

   List the items or services. Describe each product or service, its quantity, and its unit price. Billsato calculates each line and the subtotal automatically. Tick “Add descriptions” if a line needs more explanation than its name gives.

4. 4

   Set your tax rate and discount. Enter the tax rate for your region, or leave it at zero if the transaction is tax exempt. Apply a percentage or fixed-amount discount to the invoice, and the total updates as you type.

5. 5

   Add notes or a memo. Include payment instructions, terms such as “Net 30” or “Due on receipt”, or a short thank-you. Whatever you write appears at the foot of the finished invoice.

6. 6

   Check the live preview. The finished PDF is drawn beside the form and redraws as you type, so what you see is exactly the document you are about to send — no guessing, no generate step.

Billsato is a free invoice maker that handles the layout and the math for you, so you can create invoices that look professional in a couple of minutes.

• Your logo and brand colors: Upload your company logo (PNG, JPG or SVG) and it prints at the top of every invoice. Its main color becomes the invoice theme, or choose another theme color.

• 37 currencies and 67 languages: Bill in US dollars, euros, pounds and 34 other currencies, with every amount formatted correctly. Switch the page to any of 67 languages and the invoice and its PDF are written in that language too.

• Automatic calculations: Line totals, tax, discounts, shipping and the amount due are worked out as you type, so the math on your invoice is always right.

• Invoice numbers and due dates: Every invoice gets a unique invoice number you can change, and the due date follows from your payment terms: Net 15, Net 30 or any number of days.

• How your client pays you: Add bank transfer details, a payment link with a QR code, check instructions, or payment apps such as Zelle, Venmo and PayPal. They print on the invoice, and your client pays you directly.

Looking for an invoice template? Billsato works like one, without the spreadsheet. Instead of downloading a Word or Excel invoice template and adding up the totals yourself, you fill in this online invoice template and download the finished invoice as a PDF.

The layout already has everything an invoice needs: your business details, the client's details, an invoice number, the invoice date and due date, line items, tax and payment instructions. Choose US Letter or A4, add your logo and pick a theme color; the live preview shows exactly what your client will receive.

Use it as a simple invoice template for freelance work, a service invoice for consulting, or a sales invoice for products. Label each line as an item, product or service, hide quantities for flat fees, or add extra fields such as a PO number.

An invoice is a formal document that a seller sends to a buyer to request payment for goods delivered or services rendered. It is a record of the transaction for both parties and an essential part of business accounting.

Invoices are not the same as receipts or bills. An invoice is sent before payment is made — it is a request. A receipt is issued after payment has been received. A bill is what the buyer sees; an invoice is what the seller sends. The same document, two perspectives.

Every business that sells products or services — freelancer, small business, or large enterprise — needs invoices to track revenue, manage cash flow, and keep accurate financial records for tax purposes. A clear, itemized invoice also makes your business look established and builds trust with clients.

A complete invoice should contain the following:

• Your business details: Business name, address, phone number, and email. If you have a tax or VAT registration number, include it here.

• Client details: Your customer's name, company, address, email, and phone number.

• Invoice number: A unique identifier. Use a consistent system — sequential (INV-00001) or date-based (2026-08-001) — to keep records organized.

• Invoice date: The date the invoice is issued.

• Due date: When payment is expected. Common terms are "Due on receipt", "Net 15", or "Net 30".

• Line items: Each product or service, the quantity, the unit price, and the line total.

• Subtotal, tax, and total: The sum of all line items, any applicable tax or discount, and the final amount due.

• Payment instructions: How the client should pay: a payment link, bank details (ACH routing and account number in the US, IBAN and SWIFT/BIC internationally), who to make checks payable to and where to mail them, or a payment app such as Zelle, Venmo, or PayPal. You can list more than one. US clients often need a W-9 before paying a new contractor, so add "W-9 available on request" to your notes or send it with your first invoice.

• Notes or terms: Late payment fees, early payment discounts, or anything else the client needs to know.

Once your invoice is ready, you need to get it to your client.

• Email (recommended): Attach the PDF. It is the fastest, cheapest, and most reliable method, your client receives it instantly, and your sent folder is the delivery record. Mention the invoice number, the amount due, and the due date in the message.

• Post: Print and mail it. Slower and more expensive, but some clients and industries still prefer paper. Always keep a digital copy.

• An invoicing platform: Accounting software can send invoices directly, often with read receipts, automatic reminders, and payment links.

• In person: For local or on-site work, hand it over directly — then follow up with a digital copy so both parties have a record.

Timing matters. Send your invoice as soon as the work is complete or the product is delivered. The longer you wait to invoice, the longer you wait to be paid.

For project work, invoice on the day you deliver the final output. For ongoing services, set a billing cycle — weekly, biweekly, or monthly — and invoice on the same day each cycle so your client knows when to expect it.

For large projects, consider milestone invoicing: bill a portion at key stages, for example 30% upfront, 40% at the midpoint, and 30% on completion. It keeps cash flow steady and reduces the risk of chasing one large sum. Always agree payment terms before starting work — clear expectations upfront prevent disputes later.

• Send invoices promptly: The sooner you invoice, the sooner you are paid. A late invoice signals that payment is not urgent.

• Be clear on terms: State the due date, accepted payment methods, and any late fees on the invoice itself. Ambiguity invites delay.

• Offer several ways to pay: ACH or bank transfer, card through a payment link, Zelle, Venmo, PayPal, or check. List every method you accept — the easier paying is, the faster it happens.

• Send reminders: A friendly note a few days before the due date, and a follow-up shortly after if nothing has arrived.

• Reward early payment: A small discount — 2% for payment within 10 days — can move you up the queue.

• Track what is outstanding: Keep a record of every invoice and its status. A spreadsheet works; invoicing software works better.

• Charge late fees: If your terms include them, apply them consistently. It establishes that your terms are real.

Different situations call for different documents. The most common are:

• Standard invoice: A straightforward request for payment after goods or services have been provided.

• Proforma invoice: A preliminary invoice sent before work begins, outlining expected costs. A quote, not a demand for payment.

• Recurring invoice: For ongoing services billed at regular intervals — retainers, subscriptions, maintenance contracts.

• Credit note: Issued to reduce the amount on an invoice already sent, for returns, overpayments, or billing errors.

• Debit note: The opposite of a credit note — issued to increase the amount due, usually for extra charges.

• Commercial invoice: Used in international trade. Carries customs information such as country of origin, tariff codes, and Incoterms.

• Timesheet invoice: For work billed by the hour: hours worked, hourly rate, and a total for each task.
