Invoice
An invoice is a document that requests payment for products or services provided by a business.
Businesses use invoices to record transactions, communicate payment details, and collect payments from customers in an organized and professional manner.
Quick Reference
Definition
An invoice is a document issued by a business that lists the products or services provided, the amount owed, payment terms, and payment instructions. Invoices serve as both a payment request and a record of the transaction for the business and the customer. They are commonly used for one-time purchases, recurring services, consulting projects, subscriptions, and business-to-business transactions.
Why This Term Matters
Invoices help businesses collect payments accurately and maintain organized financial records. A well-prepared invoice clearly communicates what was provided, how much is owed, when payment is due, and how payment can be made. Proper invoicing supports cash flow, bookkeeping, customer communication, and financial reporting.
How It Works
After delivering a product or completing a service, the business creates an invoice containing the customer's information, a description of the products or services, pricing, taxes if applicable, payment terms, and accepted payment methods. The invoice is sent to the customer by email, through an online portal, or as a printed document. Once payment is received, the invoice is marked as paid and becomes part of the business's financial records.
Examples
- A freelance designer sends an invoice after completing a website project.
- A monthly maintenance company invoices customers for recurring services.
- A software company invoices a business annually for an enterprise subscription renewal.
