Duplicate Orders. Duplicate orders should not be recorded in the studio register, as it will be far more convenient to have a special place for keeping a record of these orders. It is advisable to procure a cheap commercial cash or day book and in it record all duplicate orders, first giving the original register order number, then recording the customer's name and number of pictures desired, the style of finish, the total amount of order, the amount deposited and day when promised. A slip containing the register number of each negative wanted should be prepared from the duplicate book each day and the negatives brought to the office where the duplicate order is written on the envelope. In addition to the order there should appear the date of duplicate order and the date promised.
726. A collection of good negatives is one of the biggest assets to the business. When a duplicate order is received all that is necessary is to look up the negative and finish the picture. There are no plates to pay for, no sitting to make, no developing of the negative, printing proofs or retouching, and for this reason duplicates are usually supplied at a slight reduction of the price charged for the original order. Generally a reduction of $1.00 on the dozen is made. For example, if the original order was $5.00 per dozen, the price for duplicate orders would be $4.00. Reference to the studio register will acquaint you with the price originally paid and also give you information as to the style of picture, etc.
727. You should require at least a deposit on duplicate orders, although it is customary with many photographers to have the full amount paid at the time the order is given.
728. On all of your printed matter or stationery it is well to call attention to the fact that duplicate orders can be had any time and that they will be finished equally as good as the original order and at a slight reduction in price.
Checking Up The Day's Work. The amounts paid - which are designated in the right hand corner of the stubs (duplicates of the original receipts) - for a day's work should be added at the end of the day, or in case of small studios, at the end of each week, and this amount placed in the cash book as shown in Illustration No. 94. The numbers of the receipts issued that day, or for the week, should also appear in the cash book as shown.
730. When the duplicate receipts for the day or the week have been totaled, a rubber band may be placed around the used receipts and front cover, thus separating the checked up receipts from those unchecked. By placing the rubber band around the checked carbon receipts, there will be no danger of duplicating onto the receipts of the preceding day.
731. When all of the receipts in the receipt book have been issued, the book with its carbon copies should be filed in a place specially reserved for it and the date of the last receipt noted on the outside cover. Whenever it is desired to refer to any receipt, it is a very easy matter to do so when the carbon copies are filed in this manner.
