Once you connect erplain with QuickBooks, all Purchase Orders created from erplain will be sent to QuickBooks.
A new bill of expense will be created on QuickBooks as soon as a new delivery (you have received the products ordered) is created on erplain.
You can find more information about Purchase Orders and Deliveries in this article.
After the purchase order has been published to QuickBooks, we recommend adding the deliveries (bill of expense) on erplain and not on QuickBooks. Bills of expenses on QuickBooks will not be synced back to erplain.
Warning: Cancelling the purchase order on erplain will delete the purchase order on QuickBooks.
Important: Purchase orders are synchronized only from erplain to QuickBooks. If you update the purchase order on erplain, it will update the purchase order on QuickBooks, but If you update it on QuickBooks, it will not be updated on erplain.
Cost of Good Sold
Please note that QuickBooks will calculate the Cost of Goods Sold from the Purchase Orders, Bills of expense, and Invoices that are in QuickBooks. erplain does not send a separate Cost of Goods Sold to QuickBooks.
