How It Works

Describe the job. AI drafts the document. You send it.

Create invoices, estimates, and quotes with AI in 30 seconds, or fill in the form manually. Either way, you get a branded, professional document ready to download or email.

01

Describe Your Job (AI) or Fill the Form (Manual)

Choose how you want to create: tell the AI what work you did in plain English, and it drafts the line items, notes, and payment terms. Or switch to the manual tab and fill in every field yourself.

  • AI tab: Type 'Cleaned 3-bedroom house, deep cleaned kitchen, treated carpets' and the AI generates line items with quantities and rates
  • AI refines the draft through conversation — 'Add carpet treatment at $75' or 'Change payment to Net 15'
  • Manual tab: Full form with company info, customer details, and line items
  • Switch between AI and manual at any time — your data carries over

→ Whether you use AI or the form, you get a complete invoice draft ready to customize.

02

Enter Your Details

Add or confirm your company information, customer details, and line items. If you used AI, most fields are already filled — just review and adjust.

  • Company name, address, phone, and email — saved for next time
  • Customer name and address for the invoice header
  • Add line items with description, quantity, rate, and amount
  • Optional discount (% or flat), tax rate, and payment terms
  • Notes and payment instructions at the bottom

→ All fields validate in real-time. Totals update as you type.

Frequently Asked Questions

Can I use this without creating an account?
Yes. You can try the invoice generator without any account. To save documents, clone them, or email them to customers, you verify your email with a one-time code — no password needed.
How does the clone feature work?
Select any previous invoice from the dropdown and click clone. The system copies all details, auto-increments the invoice number, and resets dates to today. Edit what changed and send.
Are the fonts commercially licensed?
Yes. All fonts are from Google Fonts, licensed under SIL OFL 1.1 or Apache 2.0. Safe for commercial use on customer-facing invoices.
What happens if I hit my monthly invoice limit?
You'll see a prompt to upgrade. Your existing documents are never deleted. You can clone and download again next month, or upgrade to Lite or Plus for more volume.
Can I remove the LeadDuo branding?
Yes — on the Plus plan ($10/month). The 'Generated with LeadDuo' footer is removed from both the PDF and email.
Is my data secure?
Yes. Invoice data is stored in a secure database. Logos are stored in AWS S3. All API endpoints use authentication and rate limiting. We never share your data.
What's your refund policy?
All paid plans are non-refundable. At $5–$10/month, we keep pricing simple with no refunds or partial refunds. Cancel anytime — your plan stays active until the end of the billing period.
