What a sales invoice is

A sales invoice is the standard document that records a completed sale between a business and its customer. It lists what was sold, in what quantity, at what price, and what the customer owes once tax and any discounts are applied.

It serves two purposes at once. For the buyer it is a clear bill showing exactly what they are paying for. For the seller it is a record of revenue that supports bookkeeping and later reconciliation.

When you issue one

You issue a sales invoice after goods are delivered or a service is complete, or when your agreement calls for billing at a set point. It is the most common invoice type and applies to almost any business selling to another business or to consumers.

A sales invoice differs from a receipt, which confirms that payment has already been made. The invoice comes first and states what is owed; a receipt follows once the customer settles the amount.

What a good sales invoice contains

Start with your business details and the customer's, then itemise every product or service clearly so there is no ambiguity about what is being charged. Show quantities and unit prices, and break out tax separately from the subtotal.

Add a unique invoice number and issue date for your records, and state the payment terms so the customer knows when the amount is due. Notes for discounts, references or purchase order numbers help keep both parties aligned.

Frequently asked questions

What is the difference between a sales invoice and a receipt?
A sales invoice is issued to request payment and lists what the customer owes for goods or services. A receipt is issued after payment to confirm the money was received. The invoice comes first as a bill; the receipt follows as proof of settlement. Both are useful records, but they mark different stages of a transaction.
Does a sales invoice need an invoice number?
Yes. A unique, sequential invoice number is essential for keeping your records organised and traceable. It lets you and your customer refer to a specific transaction and helps at tax time. Receipt Caker lets you set any number format you like, so you can follow a running sequence or your own numbering scheme.
How do I add tax to a sales invoice?
Enter your tax rate in Receipt Caker and it applies the percentage to the taxable subtotal, showing the tax amount as a separate line and adding it to the grand total. Keeping tax separate makes the invoice transparent for the customer and easier for your bookkeeping. You control the rate, so it matches your local requirements.
Can I put both products and services on one sales invoice?
Yes. A sales invoice can mix physical goods and services on the same document, each as its own line item with a description, quantity and price. This is common for businesses that sell a product and also charge for installation or support. Receipt Caker lets you add as many mixed line items as you need, with totals calculated automatically.
What payment terms should a sales invoice show?
Common terms include due on receipt, Net 15, Net 30 or Net 60, which tell the customer how many days they have to pay. Choose the term you agreed with the buyer and state it clearly on the invoice. Receipt Caker lets you type your terms into a notes or terms field so expectations are set, though it does not track or enforce the due date.
Does Receipt Caker track whether my invoice is paid?
No. Receipt Caker is a document generator that builds and exports your sales invoice in the browser. It does not process payments, send reminders, or mark invoices as paid or unpaid. You use the exported document as your bill and record and manage payment status in your own bookkeeping.
