62 THE MODEL STOCK PLAN stocks which exist in almost every store, stocks that do not turn more than twice a year and then do not turn except at a loss.! It is only possible in this book to outline briefly the general facts that records should give the merchant who uses the Model Stock Plan. Obviously, no set of forms can be devised that will fit all classes or sizes of stores. A large department store requires extremely detailed information in order that each department may be planned for and adequately con- trolled, both as a unit and as part of a coordinated whole. A small, single-line store, such as, say, a store doing an annual volume of $350,000, requires few records, if the proprietor is on the job every day. A large, metropolitan store may require, to yield the greatest total profits, departmental records comparable in their completeness to those used in a department store of comparable volume. Almost every line of business has its distinctive method of keeping records to fit its peculiar needs. Many retail trade associations have developed standard methods of accounting and planning which can readily be adapted to the Model Stock Plan. The Model Stock Plan, as has repeatedly been pointed out in these pages, is a planning and control method rather than a set of forms and store systems. Any merchant who absorbs the principles underlying the plan can devise or find the forms to supply the operating facts he needs. We shall, therefore, consider here merely the general outlines of the records of the Model Stock Plan in terms of the informa- tion they must yield. Because the department store problem is the more complex, we shall illustrate our principles in general terms applicable to department stores. The mer- chant whose record problem is simpler can easily simplify and eliminate for himself to reduce the statement to terms applicable to his specific merchandising problem. 1 The Louisville Grocery Survey, made in 1928 to 1929 under joint auspices of the U. S. Department of Commerce and local and national grocery inter- ests, disclosed by inventorying typical independent grocery stores that prac- tically all of them had on hand important quantities of merchandise that had been in stock anywhere from many months up to several years. Some of its Vande found had been discontinued by the packers three or four years
