New to invoicing? This complete guide walks you through creating your first professional invoice, from essential elements to sending and follow-up.

Essential elements every invoice needs

A professional invoice must include: your business name and contact details, client name and address, unique invoice number, invoice date and due date, itemized list of products or services, quantities and unit prices, subtotal, taxes (VAT/GST), and total amount due. Don't forget payment instructions and terms.

Step-by-step invoice creation

1. Open ZeroDue and click 'Create Invoice'. 2. Select or add your client. 3. Add line items with descriptions and prices. 4. Set payment terms (Net 15, Net 30, etc.). 5. Add any applicable taxes. 6. Preview and customize the design. 7. Send directly to your client's email. ZeroDue tracks when they view it and sends automatic reminders.

Common invoicing mistakes to avoid

Never send an invoice without proofreading for errors. Always use sequential invoice numbers for accounting. Include clear payment instructions. Don't wait too long after completing work to send the invoice. Set up automatic reminders to reduce late payments by up to 40%.
