Or Generate a Complete Invoice with AI in 10 Seconds

Here's the thing about templates: they're still blank. You still have to type everything in.

If you're billing clients regularly — even just a few times a month — that's hours per year spent filling out the same fields over and over. Your business info doesn't change. Your client's info doesn't change. The only thing that's different is the line items.

Eonebill's AI invoice generator fixes this. Describe what you need:

The AI generates the complete invoice — pulls your client from your saved contacts, applies your branding, adds your payment terms and Stripe link, calculates the total — everything. Ready to review and send in under 20 seconds.

Try the AI generator free — 6 invoices/month on the free plan. Generate an invoice in 10 seconds →

What's Included in Each Template

The PDF Invoice Template

The PDF template is a single-page, professionally designed invoice. It includes:

• Your business name and logo placeholder
• Client name and billing address
• Unique invoice number (you fill in the next sequential number)
• Invoice date and due date
• Line item table (description, quantity, rate, amount)
• Subtotal, tax rate (if applicable), and grand total
• Payment terms section
• Payment instructions (ACH/bank transfer details)
• Notes field

How to use it: Download, open in any PDF editor (Adobe Acrobat, Preview on Mac, etc.), fill in the fields, and send as an attachment. The formatting stays exactly as designed — no accidental layout shifts.

The Word (DOCX) Invoice Template

The Word template is fully editable with a clean layout. It includes:

• Header with your business info (replace the placeholder with your details)
• Client information block
• Invoice metadata (number, date, due date)
• Itemized table with auto-calculated totals
• Tax line (adjustable rate)
• Payment terms and instructions
• Notes and terms section
• Footer with your contact information

How to use it: Download, open in Microsoft Word or Google Docs, replace the placeholder text with your information, add your logo (Insert → Image → Header), and save. You can duplicate the file for each new invoice and just change the line items and invoice number.

The Excel Invoice Template

The Excel template has built-in formulas so totals calculate automatically. It includes:

• Input cells for all your business and client information
• Line item table with Quantity × Rate = Amount formulas
• Automatic subtotal calculation
• Tax rate cell (change the percentage, total updates automatically)
• Grand total formula
• Multiple invoice sections (billed to, ship to, etc.)

How to use it: Download, open in Excel or Google Sheets. Each yellow-highlighted cell is an input field. Type in your line items and the totals calculate automatically. Duplicate the sheet for each new invoice.

Pro Tips for Getting Paid Faster

Even the most beautifully designed invoice won't pay itself. Here's how to increase your payment speed:

1. Send it immediately after completing the work The longer you wait to send an invoice, the more you get deprioritized. Send it the same day or the next morning.

2. Include a clear payment link If you make it even slightly hard to pay, some clients will put it off. Always include a Stripe payment link or clear ACH instructions.

3. Name the file something professional Don't email "invoice.pdf." Name it "[YourBusinessName]Invoice[Number]_[ClientName].pdf" so it's easy to find and match in their accounting system.

4. Send a short, friendly email Don't just attach the invoice and hit send. A two-line note: "Hi [Name], attached is invoice [#] for [service]. Payment is due [date]. Let me know if you need anything else!" gets opened and paid significantly faster.

5. Follow up at the right time Set a reminder for the due date. If you haven't been paid, follow up within 1–2 days of the due date — not 30 days later. The shorter the gap, the less awkward the conversation.
