Like purchase orders, Sales Order too can be added and lined up with multiple order items.  Purchase orders can be added by line up multiple order items i. e. each order may contain one or more order items (Products).  You can maintain and track a purchase order in its various stages like – Sent to Vendor, Partially Fulfilled, Fulfilled, Cancelled, etc.  This app is useful for individuals and businesses to manage and track their Purchase and Sales Orders, Inventories, multiple locations, Categories, Vendors and Customers.  You can track and maintain your customer’s records. For e. g. while adding a sales order, the customer who placed the order can be linked to the sales order section.  Then, you can track the sales order in its various stages like New Order, In Progress, Order is Ready, Dispatched, Cancelled, etc.  Each product can have multiple inventory items i. e. for one product you can maintain two or more Inventory items at different purchase and sale prices.  Goods Order Inventory System (GOIS) is an all-encompassing integrated Inventory Management & Order Management application with user friendly mobile and web interface.  A purchase order can also be linked with specific vendor and its related contacts.  You can also maintain the delivery method of Sales Order like Delivery or Pick-up.  All the fulfilled purchase orders will fill up the default inventory with the chosen ordered items.  These units can then be used while adding purchase orders or sales orders.  You can even add discount and tax information for each Purchase Order.  So, you can add more than one order item (Product) for each Sales Order.  With each organization you can add multiple related Business Units which symbolically represent various branch offices or shops of an organization.  Users can also set one default unit with a Product, but that product can also be purchased or sell using different units.
