Customers may submit a purchase order to a wholesaler. A purchase order may contain multiple products. Upon receipt, the wholesaler examines the purchase order. Orders with a total amount larger than $500,000 are dealt with directly by the manufacturer. If the order can be handled by the wholesaler, the wholesaler checks its stock level for each of the products. If either the order is too large for the wholesaler or there is insufficient stock on any product, the wholesaler forwards the order to the manufacturer and notifies the customer. Otherwise, it sends an invoice and delivery notice to the customer. In any case, the wholesaler is obligated by the manufacturer to respond to the customer within five business days of the receipt of the purchase order. When the customer is referred to the manufacturer, the sales department checks if the customer is an existing customer. If the customer is new, the customer relationship department will negotiate a framework agreement with the customer. When that is done, the customer's wholesaler is also notified with discount codes for smaller orders by that customer. The sales department then confirms the purchase order to the customer and checks inventory levels for each product. If necessary, the production department may plan and execute multiple production orders to fill the order or replenish inventory. After order confirmation to the customer, the logistics department plans the shipment of the order to the customer. Because parts of the order may be shipped to different customer locations, shipment planning is done separately for each part of an order that has a different delivery address. For shipment planning, the logistics department asks for quotes from at least three trucking companies, and must wait until two are received. After each shipping schedule is planned, it is sent to the customer for confirmation and also to the selected trucking company. The customer must confirm to the logistics department within three business days or the shipping schedule must be re-planned. Once confirmed, and, if necessary, any necessary production order execution is completed, the logistics department assembles the multiple products of each part of the order and notifies both the customer and the selected trucking company that the order part is ready. When all order parts are assembled, the sales department issues a single invoice to the customer and awaits payment, which must be received from the customer within the time frame specified in the framework agreement. When the payment is received, the wholesaler is paid a percentage of the order total as commission. Up to the point where shipping planning begins, the customer may request to amend the order. When such a request is received, the manufacturer first checks if the amended order is less than $500.000. If it is, it checks with the wholesaler if it could fulfil the order. If so, the customer is referred back to the wholesaler and the process ends. Otherwise, the sales department determines the new order terms and seeks confirmation from the customer. If the customer does not confirm within two business days, or declines the new order terms, the amendment request is cancelled and the process progresses normally. Otherwise, the order is amended by the sales department. If any production orders related to this customer order are in progress, the production department must re-plan its production orders.
