Then it is desirable to have a full knowledge of the processes of manufacture; the method of handling work in the factory, the labor saving appliances used, the new processes that have been perfected, the time required in turning out goods, the delays that are liable to occur—these are all pertinent and may furnish the strongest kind of selling arguments. And it is equally desirable to have inside knowledge of the methods in the sales department, in the receiving room and the shipping room. It is necessary for the correspondent to know the firm's facilities for handling orders; when deliveries can be promised, what delays are liable to occur, how goods are packed, the condition in which they are received by the customer, the probable time required in reaching the customer.
Another nearby source of information is the status of the customer's account; whether he is slow pay or a man who always discounts his bills. It is a very important fact for the correspondent to know whether the records show an increasing business or a business that barely holds its own.
Then a most important source—by many considered the most valuable material of all—is the customer himself. It may be laid down as a general proposition that the more the correspondent knows about the man to whom he is writing, the better appeal he can make.
In the first place, he wants to know the size and character of the customer's business. He should know the customer's location, not merely as a name that goes on the envelope, but some pertinent facts regarding the state or section. If he can find out something regarding a customer's standing and his competition, it will help him to understand his problems.
Fortunate is the correspondent who knows something regarding the personal peculiarities of the man to whom he is writing. If he understands his hobbies, his cherished ambition, his home life, he can shape his appeal in a more personal way. It is comparatively easy to secure such information where salesmen are calling on the trade, and many large houses insist upon their representatives' making out very complete reports, giving a mass of detailed information that will be valuable to the correspondent.
Then there is a third source of material, scarcely less important than the study of the house and the customer, and that is a study of the competitors—other firms who are in the same line of business and going after the same trade. The broad-gauged correspondent never misses an opportunity to learn more about the goods of competing houses—the quality of their products, the extent of their lines, their facilities for handling orders, the satisfaction that their goods are giving, the terms on which they are sold and which managers are hustling and up to the minute in their methods.
The correspondent can also find information, inspiration and suggestion from the advertising methods of other concerns—not competitors but firms in a similar line.
Then there are various miscellaneous sources of information. The majority of correspondents study diligently the advertisements in general periodicals; new methods and ideas are seized upon and filed in the "morgue" for further reference.
Where a house travels a number of men, the sales department is an excellent place from which to draw talking points. Interviewing salesmen as they come in from trips and so getting direct information, brings out talking points which are most helpful as are those secured by shorthand reports of salesmen's conventions.
Many firms get convincing arguments by the use of detailed forms asking for reports on the product. One follow-up writer gets valuable pointers from complaints which he terms "reverse" or "left-handed" talking points.
