What is billing?
Billing is the process of creating and sending a record that shows how much money a customer owes for products or services they have used. It lists items, prices, taxes, and the total amount due, and tells the customer when and how to pay.
Let's break it down
- Invoice: The document that details the charges.
- Line items: Each product or service listed with its price.
- Subtotal: The sum of all line items before taxes or discounts.
- Taxes/fees: Additional amounts required by law or the provider.
- Total: The final amount the customer must pay.
- Due date: The deadline for payment.
- Payment methods: Ways the customer can pay (credit card, bank transfer, etc.).
Why does it matter?
Billing keeps businesses paid for what they deliver and helps customers understand what they owe. Accurate billing builds trust, prevents disputes, and ensures cash flow so a company can keep operating and growing.
