Invoice
A document requesting payment for goods or services.
An invoice is a formal document sent from seller to buyer detailing goods or services provided, amounts owed, payment terms, and due date. A proper invoice includes your business name and contact info, the client's details, a unique invoice number, line items with descriptions and amounts, payment terms, and accepted payment methods. Invoices create the legal basis for collecting payment.
Example
A web developer sends Invoice #2024-047 to a client for $3,500 covering website redesign and SEO setup, with Net 30 payment terms and a link to pay online.
Why It Matters for Your Business

Practical Tips
