AI Invoice Generator

Generate a professional invoice PDF from your business details, line items, and notes. Totals are calculated, formatting is proper, and the invoice number is auto-assigned.

Pro AI tools send document content to xAI.

AI Invoice is a Pro feature — included in PDFwarp Pro at $9 USD/month along with every other tool and unlimited conversions.

No file upload. From, To, and line items are required; notes default to 'Payment due within 30 days'. The server assigns Invoice # INV-YYYYMMDD- plus a padded user id, today's date, and asks xAI to format the invoice text. ReportLab writes a PDF unless the text is a non-Latin script, in which case you get Word. There is no logo slot and no tax engine. Pro only.

Why use PDFwarp for AI Invoice?

How to use AI Invoice — step by step

  1. Enter sender, recipient, and line items.
  2. Add notes or payment terms if you want something other than Net 30.
  3. Download the file and check the arithmetic before you send it.

Tips & best practices

One line item per line

Enter items as 'Description: $Amount' on separate lines. Ask for tax in the notes if you need a tax line — there is no tax setting.

Any currency — just include the symbol

$, €, £, ¥, R$, CA$ — the invoice uses what you typed. Don't mix currencies on the same invoice.

Check the math

The model adds. Models mis-add. Verify subtotal and total before this goes to a client or into your books.

Under the hood

Auth-only route

Like AI Write, there is no @validate_files. Pro and the daily AI cap are enforced, then From/To/Items are required. Empty notes become 'Payment due within 30 days'.

Number format

INV-{YYYYMMDD}-{user_id:04d}. That is a convenience label, not a gapless statutory series. Change it in the PDF Editor or regenerate in Word if your books need a different scheme.

Typesetting

build_pdf_output with title 'Invoice {number}'. Unicode → DOCX. max_tokens=2048. No line-item database is stored on our side.

Frequently asked questions

Can I customize the invoice format?

Only through the text you enter. Logos, letterhead, and saved clients are not supported.

What currency is supported?

Whatever symbol you put on the line items. The model does not convert currencies.

Is the invoice number unique forever?

It is unique per user per calendar day in the usual case (one invoice that day). Two invoices the same day from the same account will share the same number unless you edit it.
