Make an Order:

• When a customer name has been entered in this form, if it matches (exactly - case sensitive) with any of the existing privileged customer, discount allowed for him will be automatically generated in this form. If not discount will be zero
• And then user needs to select one of the available books. When a book has been selected, the price of the book and quantity available will be automatically displayed
• And then user needs to enter the quantity of books customer needs
• And then total amount customer needs to pay will be automatically generated based on price, quantity ordered and discount available to customer

In this way sales person can make an order for a customer using this form

Confirm payment: 

When a customer pays the total amount regarding a particular order, Finance department can confirm payment for that order by specifying the mode of payment. Upon selecting an existing order, name of the customer and total amount will also be displayed in the form which cannot be edited. Only those orders whose payment is not confirmed yet will be available in this form

Whenever Finance department confirms payment for an order, Inventory management department can deliver books for that order. Only those orders whose payment is confirmed and Delivery is pending will be available in this form. If available inventory is less than the number of books need to be delivered for that order, then user cannot deliver that order (System will not allow). If available inventory is sufficient to deliver that order, then user can deliver that order. And in this case after successful delivery of that order, inventory remaining will be updated correspondingly.
