AI Invoice Generator

A professional invoice must include your business name and contact information, client details, a unique invoice number, the invoice date and due date, itemized line items with descriptions, quantities, and rates, subtotal, applicable taxes, total amount due, and accepted payment methods. Our generator includes all these elements automatically, ensuring your invoices look polished and contain everything needed for prompt payment.

Use a consistent numbering system such as sequential numbers (INV-001, INV-002), date-based codes (2024-001), or client-prefix codes (TECH-001). Avoid gaps in numbering as this can raise questions during audits. Our generator creates a suggested invoice number, but you should maintain your own numbering sequence to ensure consistency across all your invoices and compliance with accounting best practices.

Net 30 (payment due within 30 days) is the most common term for B2B invoices. Net 15 or Due on Receipt helps improve cash flow for smaller businesses. Consider offering a small discount (e.g., 2/10 Net 30 — 2% discount if paid within 10 days) to incentivize early payment. Choose terms that balance your cash flow needs with your client relationship and industry standards.

Tax requirements vary by jurisdiction and service type. Generally, include the applicable sales tax or VAT rate, show the tax amount as a separate line item, and display the total including tax. Some services may be tax-exempt — verify with your local tax authority. Our generator calculates tax automatically based on your specified rate and separates it clearly on the invoice for transparency.

Start with a polite payment reminder email at the due date. Follow up weekly for the first month, then consider adding late payment fees as specified in your terms. For persistent non-payment, send a formal demand letter, consider a collections agency, or pursue small claims court for smaller amounts. Including clear late payment terms on your invoices from the start helps prevent disputes.
