It is possible to create orders and invoices in QuickBooks directly from Legrand. To do this, select the company in Legrand for which you wish to create the order. Note that this customer should already exist in QuickBooks, and should be linked to the Legrand record.
From the company record, click on the Accounting tab, and then on the blue Accounting Menu. From the accounting menu that pops up, you can select either to create a sales order or an invoice directly from Legrand.
