ment of any particular type is available to meet requirements of jobs, in order to determine whether to purchase the equipment needed from time to time. When purchases of equipment are made, the quantity bought is entered both in the received column for the job or yard to which the equipment is delivered and in the total column. When equipment is moved, shipping lists (Form 13) are prepared for each shipment. When the office receives advice. of the movement of equipment, the job shipping it is given credit in the return column for the quantity sent, and the job receiving it is charged in the received column. The difference between the received and the return columns for any job represents the balance on hand. PHYSICAL INVENTORIES. A physical inventory should be taken on each job at intervals not more than a month apart. The inventory is sent to the office and there compared with the record shown by the inventory movement sheets. An investigation is immediately made whenever the inventory does not fully account for the balance of equipment on hand appearing on the office record. If the investigation develops that any tool has been lost or broken, the quantity so lost or broken is noted in the return column of the inventory movement sheet. A report of the value of equipment lost or broken should be made to the accounting department for the purpose of. reducing the amount of fire insurance in force whenever the total amount involved justifies making the change. Shipping Control The shipping lists (Form 13, page 49) are serially numbered before issue to jobs. The office keeps a shipping list control sheet (Form 15). As a book of shipping lists is sent to a job, the serial number of the book and the job name or number are entered at the head of a column. When individual shipping lists are received, a check is made in the columns provided for the original (white) and triplicate (yellow) copies. When this control record shows that either the original or the triplicate, or both, are not received promptly, action is taken to locate the missing shipping list. Each column represents an issued book of shipping lists. A check mark is placed in the "White" column when the original is received and one in the "Yellow" when the triplicate is obtained. After billing is completed, the number of the invoice or credit memorandum is entered in the third column. Control of Billing When both the receiver's and the sender's copies of shipping lists are received in the office, invoices and credits are prepared. The job receiving the shipment is charged and the job shipping is credited. The system of control, as well as that of pricing and charging for equipment, is discussed in detail in the accounting section of this book, in Chapter VIII. |
