Hi there jennielouise31-m,
Thanks for reaching out about your invoices. QuickBooks Online is a great tool able to assist you in keeping track of sales and expenses so you can see the profit of your company. I can provide some information about creating invoices with time.
If you create Weekly Timesheets, or Time entries for your employees, you can add them to an invoice by clicking on +New, then Invoice.b There isn't an option to add them to an invoice directly from the payroll tab itself.
if you have any other questions, feel free to reach out here.
