The following activities describe the sales systems of Samsan Pharmaceutical Berhad. Samsan Pharmaceutical Berhad (SPB) sells medical supplies to hospitals, clinics, and pharmacies. Customer places orders through email to the SPB's Sales Department office. SPB uses an ERP system for all of its business processes.

• The sales process starts when the customer sends the purchase order through email to SPB's Sales Department. The sales clerk searches the customer's name in the sales order system and retrieves the customer record and displays that data on the sales order entry screen. The sales clerk examines the data on the screen to ensure that the correct record has been retrieved. If everything is correct, the sales clerk enters the items and the quantities being ordered by the customer. If the customer is new, the sales clerk will create a new customer profile in the system and enters the order information. As the order is entered, the system compares the amount of the order to the available credit to ensure that the purchase does not exceed the credit amount limit. If the purchase is exceeded the credit limit, the purchase will be declined. The sales clerk saves the order and the system creates a sales order record and displays the sales order number after the purchase is approved.

• The warehouse clerk creates and prints a picking ticket based on the information retrieved from the sales order. The clerk picks the goods from the shelf, wrapped, attached with the picking ticket, and sends to the shipping department. The warehouse clerk updates the inventory master file (for item code and quantity shipped). The shipping clerk retrieves the picking ticket from the system, creates, and prints the packing slip. The packing slip is attached to the goods and is given to the carrier for transportation to the customer.

• The accounts receivable clerk retrieves the packing slip and sales order information then creates a sales invoice. The accounts receivable clerk creates a sales journal. The sales invoice is printed and sent to the customer. The general ledger clerk then posts the sales journal to the general ledger.
