What you need before you start

• Your company name, email, and address
• Client (bill-to) details
• Line items: description, quantity, and rate

Step 1 — Open the free invoice generator

Go to the SingleInvoice homepage. You can fill the invoice form immediately — no signup required until you save.

Step 2 — Add your company and logo

Enter your business name and contact details. Upload a PNG or JPG logo so the PDF looks branded and trustworthy.

Step 4 — Add discount and taxes

Add a discount if needed, then create custom tax lines (GST, Sales Tax, VAT, etc.) with your own name and percentage.
