1. Start a new sales receipt. Click + New, then Sales receipt, found under the Customers column alongside Invoice.
2. Pick the customer. Use the dropdown, or add a new customer right there without leaving the screen. For a one-off walk-in sale, a generic "Cash customer" entry works fine if you don't need to track them individually.
3. Choose the payment method. Select cash, check, credit card, or whatever applies. This matters for your reports later, so it's worth picking the real method rather than defaulting to whatever's first on the list.
4. Set where the money goes. Choose Undeposited Funds if this sale will be grouped with others into one bank deposit later, which is the usual choice for card and check payments. Choose the bank account directly if this is cash you're depositing on its own.
5. List out what was sold, line by line. Same as an invoice: pull items from your products and services list for automatic pricing, or type a line in by hand. Add as many lines as the sale actually has.
6. Apply sales tax if it applies. If the items are taxable and you've got sales tax set up, QuickBooks calculates it automatically based on the customer's address; double-check the rate looks right before saving, especially for an out-of-state or out-of-county sale.
7. Save, then print or email. Choose Save and send to email a PDF immediately, Print or Preview for a physical copy, or just Save if you don't need to deliver anything right now.
