When a customer accepts your estimate and agrees to pay a fixed amount (rather than for time and costs), you can turn the estimate into an invoice.
A record of what you've sold to a customer. You send an invoice to your customers so they know what they need to pay you. Let's say you own a pirate supply store. You would send Captain Hannah the Horrible an invoice for the twelve eye patches, two peg legs, and three parrots she bought last week.
Note: Don't confuse invoices with bills. In QuickBooks, bills are what your vendors send you for you to pay them.
Billing for actuals? If you've already entered your actual time and expenses and assigned them to this job, you use a different method to invoice your customer for your costs. See instead Invoicing for actual costs.
The invoice that appears has all the information from your original estimate filled in. If the estimate included subtotals for group items, other subtotals, discounts, or sales tax, these items appear on the invoice. The prices on the invoice automatically incorporate any markups from the estimate.
You can edit the invoice just as you would any other invoice. You can add additional line items, modify any of the quantities or amounts, or delete line items that don't apply.
