Differences between the Sales Order and the Purchase Order


Please anybody explain me about the differences between the Sales Order and the Purchase Order



I apologise if this is too simple for you but it answers your question as I believe it is phrased.

Sales Order, where you sell items to a customer. The form is used to ship stock, decreasing inventory, and to ultimately invoice the customer and create the liability on the customer.

Purchase Order, where you as a business buy inventory. The form is receive stock, increasing inventory, and, if you wish, to process the vendor invoice against and create your own liability to the vendor.

A kind of worrying question really in this forum if you are trying to sell the advantages of the software.

Maybe you want to use the search function of the board and it gives you some answers.

And I really hope it is posted in the wrong forum as well. Sure you wanted to post it into the Sales & Pre Sales Forum?

Hi Sudhir

There are 1000’s of published work in this area, you just need to dive in and start. Ask local professionals for recommended reading and go from there, what would be good advice in the UK may not be where you are.

I would suggest getting a general business education first, to learn about general business processes. If you don’t know the difference between a sales order and a purchase order, then no ERP product will make any sense to you.
