Printing on demand means that publishers can print the exact quantities ordered by retail outlets, rather than estimating in advance how many books are required and often printing too few or too many. The average printing turnaround time for DIPL is two business days for small orders and five to ten business days for large orders. In addition, five years ago, DIPL further expanded its earnings base by having publisher’s titles available as searchable ‘e-books’ that could be downloaded directly by readers from DIPL’s website.Purchase and InventoryDIPL purchases 50% of its inventory requirements of paper, ink and binding materials from Australian sources and 50% from Asian countries. When inventory received at DIPL’s warehouse (whether it is purchased from Australia or Asia), the accounts payable clerk, Bill Jimmy, records the arrival of the inventory and also its value and quantity in the accounts payable system. Inventory is paid for the relevant currency of the country from which it is purchased. Raw materials have been valued at average cost and an allowance for inventory obsolescence has existed in previous years to cover the estimated decline in value from the effects of storage hazards. Work in progress is immaterial due to the quick turn- around time of printing jobs. Any work in progress is assessed at the cost of raw materials and labour and proportion of manufacturing overheads based on normal capacity. At year end, the warehouse is closed from 28 to 30 June for stocktake, so sales must be invoiced in the system by close of business on 27 June. The stock must have been sent to the customer (that is, it must either be on track, ship or plane on its way to the customer, or it must already have arrived at the customer; it must no longer be in DIPL’s warehouse).‘Print on Demand’ revenue and receivablesEach time a publisher wants to add a book to DIPL’s ‘digital library’ (a server storing all of the publisher’s books in a digital format, ready to print), it emails the book to DIPL in PDF format. The digital library is backed up at the close of business every day, with the backup tapes kept off site. Once the book is stored in the digital library, the publishers can order copies to be printed as required.When the publishers confirm the order, the accounting system automatically retrieves details of the publisher’s credit record and stops any orders from publishers that have exceeded their credit terms and limits. A printout of the transactions history of the publishers is generated and must be signed by both Helena Keng, the head of publishing, and Jane Roger, the head of accounts at DIPL, before the order can continue, after the transaction history has been signed and dated, accounts receivable staff file it.
