About Invoice Generator
An invoice records an amount requested from a customer after goods or services are supplied or agreed. This generator organizes party details, dated billing information, itemized charges, and commercial notes; the backend calculates the authoritative monetary totals.
Why use this tool
- Keep descriptions, quantities, and prices in a clear table.
- Include a due date and terms with the amount requested.
- Generate consistent totals from tax, discount, and optional shipping.
Privacy and security
Invoice details travel directly from your browser to the Choosify document API to generate the PDF. WordPress does not receive or store the submitted details or generated document. API processing is temporary and follows backend behavior.
Frequently asked questions
Which totals does the invoice API calculate?
It calculates line amounts, subtotal, discount, taxable amount, tax, shipping, and grand total. The browser estimate is convenient; the PDF uses server totals.
How are discount, tax, and shipping applied?
The fixed discount is deducted from subtotal, tax is calculated on the taxable remainder, and shipping is added afterward.
Can the due date be earlier than the issue date?
No. It must be the same date or later.
Does this generator collect customer payments?
No. It creates a PDF only; it does not charge cards, transfer funds, or confirm payment.
