You can use the Combine orders into an invoice option under the More actions button in the Search view to combine several sales orders into a single invoice.
With the Combine orders into an invoice function, you can easily combine multiple orders into a single invoice, for example if you are invoicing sales orders created for a specific customer once each month.
Find the orders you wish to combine first, for example by using the Search function, and click on More actions > Combine orders into an invoice.
Choosing the option opens a view listing the orders included in the search results. Select a single order from the list to provide header information for the invoice and all orders whose row information will be compiled in the invoice.
You can select the row information of all orders by clicking on the Select all button.
Creating an invoice
After you have selected the desired orders from the list, you can compile them into a single invoice by clicking on the Create a new invoice button. The program will then prompt you to confirm the action. When you click on the Continue button, the status of the original orders will change to Invoiced. The accounting pages of the orders will also be deleted and a new receipt (the invoice) will be created from the orders.
The Unfinished invoice created from the orders will then open, and you will be able to edit it in the normal fashion. The invoice’s Order reference field will indicate the orders on which the invoice is based.
