Sales Store Clerical Series, GS-2091 TS-46 June 1963
One of the most important clerical functions involved in sales store operations is the checking or
check-out function. The basic check-out function consists of operating a cash register to list and
total the prices of individual items purchased, collecting cash and making change, and
reconciling cash receipts with the cash register tape. Variations from these basic check-out
duties have developed as the result of changes in sales store operations and the availability of
different kinds of mechanical equipment. Among such variations are check-out duties that are
concerned with both charge and cash purchases, those which are concerned only with charge
purchases (and, hence, do not involve the handling of cash items), and those which involve the
operation of bookkeeping, billing, or similar machines instead of cash registers.
Operation of a cash register differs according to the kind of equipment used and the kind of
entering operation performed. Cash registers vary in number and types of keys, number of
accumulating banks, kinds of printing mechanism, and other mechanical features. Differences in
the mechanical features affect the kind of entries that can be made on a cash register tape. Some
cash registers can be used only to record a simple listing of item prices without classification or
other additional information. Multiple cash registers are normally used to departmentalize prices
in various categories, enter surcharges, indicate whether purchases are cash or charge, identify
customers or account numbers to be charged, or provide other information used for accounting,
stock control, or similar purposes. Bookkeeping or billing machines may be used to accomplish
any or all of these purposes. When these machines are used, the purchase totals and other related
information involved are normally entered directly on ledger or stock control cards.
Certain clerical knowledge and abilities must be applied simultaneously with the operation of
mechanical equipment in order to perform check-out duties with acceptable speed and accuracy.
Check-out work characteristically includes responsibility for insuring that the prices charged are
accurate. This requires knowledge of the current prices of stock items in order to determine
whether (a) prices marked on items are correct or (b) reference to price lists is necessary. The
work also requires knowledge of the nature, quality differences, size and pack variations, and/or
other characteristics of stock items. This knowledge is essential in order to identify stock items
rapidly and to distinguish quickly between closely similar items. In addition, competent
performance of check-out work requires knowledge of established procedures describing the
kind of entries to be made, the order in which entries are to be recorded, the action to be taken in
cases of operator error or of machine malfunctioning, the practices involved in respect to returns
and exchanges, and other matters of a similar nature. To the extent such procedures describe
these procedures in only general terms, or do not describe all of the matters involved in the work,
the use of judgment may be required in carrying out the work. The time pressures under which
check-out duties are usually performed are such that the checker is seldom able to consult
written guides or the supervisor on these matters. The extent to which these knowledge and
abilities are required in check-out work is reflected in the number and variety of stock items
involved, in the number and kind of entries recorded, and in the number and specificity of
applicable procedures.
The complexity of reconciling the cash register (or other machine) tape or total with cash
receipts or with charge entries varies. In its simpler form this reconciliation normally involves
comparison of the total of the cash items or charges with the total shown on the cash register or
other tape as adjusted for over- or under-rings. Errors causing failure to balance are located by
