There is a way to use the sales order to keep control of the delivery to the customer and the order from the vendors?
No. Sales orders are not linked to anything else. They have no financial impact. But you can use custom fields to track status. Search the forum. Methods have been discussed many times.
Please point me where to look, i am very new to manager.
The main Guide about custom fields is here: Use custom fields | Manager. Search the forum using the magnifying glass in the upper right corner of the window.
