Integrate your tax invoice and purchase order records with a snap!
On the tax invoice page, iCount has created a clear field for you to list your purchase order numbers so that customers can better understand their bills.
Do you like this feature so much that you want to make it mandatory for all Invoices? Simply go to the menu and select: System-> Settings -> Accounting -> Accounting Settings > and check the box that says “Must fill PO number in invoices and invoice receipts”. Then click “Save’. All invoices will always require a purchase order number going forward!
