What to Include on a Professional Invoice
A complete invoice should always include:
- Your business name and contact info
- Customer name and billing address
- Unique invoice number (e.g., INV-001)
- Invoice date and due date
- Itemized line items with quantity and unit price
- Subtotal, tax, discount, and total
- Payment terms (Net 30, Due on Receipt, etc.)
- Notes or payment instructions
Our tool includes all of these fields by default.
Standalone Invoice Generator vs. Built-in Shopify Invoices
Shopify generates invoices automatically for orders placed through your store. However, many merchants still need a standalone free invoice generator shopify solution for:
- Services not sold through Shopify
- Pre-order or custom manufacturing quotes
- B2B clients who pay outside Shopify Payments
- Freelance or agency work billed separately
