D. S. Copyright 1923 By WHITFIELD COBB HE purpose of this paper is to show how a professional man, whose income is derived from fees offset by necessary practice operating expenses, may easily obtain such in¬ formation as is necessary in making income tax returns , may know his Cost and Prof it, and may also have a clear knowledge of all his financial transactions. The writer, who was an experienced bookkeeper before taking up a profession, in order to have such information has designed COBB'S CASH-JOURNAL, which has been in use for several years, and which has now been perfected to give, with very little work, much val¬ uable information about the condition of one’s finances. The Cash-Journal itself has instructions printed on the inside cover page; but, in order to make the explanations even more clear, I have had photo-etchings made of sheets showing ac¬ tual entries of various kinds which might come up in practice. These cuts which follow are half the dimensions of the originals and illustrate perfectly the book and its use. The double entry idea is carried out, and it must be understood that (with the exception of Dailv Practice, column for which is to the extreme left of page), all items must show in two or more columns and the totals of the entries in the “Dr.” columns must equal the total of entries in the “Cr.” columns. To grasp the simplicity and value of the System, trace in both Dr. and Cr. columns on sheets marked "Specimen Entries” the following items: Mch. 29—Totals brought forward from foot of p-cording page. Mch. 30—Gross practice (for the day) ----- $47.00 Cash Practice - -- -- -- -- - 16.50 Deposit - -- -- -- -- 63.00 Mch. 31— Mrs. O. E. Davis paid bill ----- 27.00 Gross Practice - -- -- -- - 26.00 Cash Practice - -- -- -- - 19.50 Paid Banner Realty Co. office rent for March, check No. 565 - -- -- -- - 35.00 Twin City Dental Depot, for supplies, $20; repairs, $2.50; new equipment, $5.00; check No. 566 - - - - - - - - - - 27.50 Miss Mary Knox, balance salary office girl - 27.75 Mr. J. C. Reynolds paid $10 and was allowed frill credit for his account, $12-50, the bal¬ ance, $2.50, being charged to discounts (col¬ umn 10). Cash was paid as follows: 1 doz, towels, $3; laundry, .90; postage, $1 - - - - 4.90 Cash drawn out for personal use - - - 26.00 (Charged to Whitfield Cobb) The Motor Co. auto expense - - - - 48 62 These completing the entries of the month, the columns are then totaled, and these totals are used on Summary and Cost Ledger Sheets as explained later. The total of Column 3 is subtracted from total of Column 2; the remainder, repre¬ senting balance of cash on hand, is written down under date of April 1. Total of Column 6 is subtracted from total of Column 4, being balance in bank at end of month and is entered on same line with cash on hand under date of April 1. In order to carry out the double entry idea and make the balance automatic, these two balances are also shown in Cr. Column No. 29. Inserts A, B and C are explained later. Apr. 1—-Balance cash on hand ------ $ 53 .] 6 Balance in Bank ------- l]Q.59 Sou. Bell Telephone A- Teleg. Co., office, $5; home, $2.50; total ------- 7.50 Eureka Coal Co., coal for home - 27.50 Gross Practice (no cash practice or deposit that day) - -- -- -- -- 33 .00 Bought from The Office Equipment Co., equipment worth $700, on which was paid $ 100 , giving notes for the balance of $600 to to be paid monthly. Standard Accident Insurance Co., claim paid me ---------- 52.75 J. M. Jones paid me for rent on dwelling $65.00 G. P. Putnam Sons Co., books for office - 16.75 Apr. 2—Gross Practice ------- 53.25 Cash Practice, $38, less a discount of $6 to minister, leaving $32 cash received. Deposit.45.00 Apr. 3—Gross Practice - -- -- -- - 39.50 Cash Practice - -- -- -- - 28.50 Deposit - -- -- -- -- 35.00 Goldsmith Bros, paid me for amalgam scrap. 10.00 This amalgam having been charged originally to Materials (Column 7), the credit should be deducted from Column 7 and entry is made in red ink or in parenthesis to show item is to be subtracted. Apr. 4—Gross Practice - -- -- -- - 25.00 Cash Practice - -- -- -- - 19.00 Deposit - - 104.16 Paid in cash Church, $4; Smith Labora¬ tory, $10; total - - - - - - 14.00 Standard Building & Loan Association - 60.00 Of this, $40 was reducing loan and $20 interest. Paid J. C. Williams for repairs to Jones Street house which I rent to J. M. Jones - 20.00 N. Y. Life Ins. Co., premium _ - - - 50.00 Apr. 5—I have a bill against R. N. Pickett for $35 pro¬ fessional services; he has one against me for $33.75 groceries; he pays me $1.25, settling both accounts. E. C. Caldwell has bill against me for plumb¬ ing, $80, (office, $70, home, $10), I have bill against him for $20; I write him check for $60, settling both accounts. I borrow from Standard Building & Loan Asso¬ ciation $3,000. They write me two cheeks, one for $172, (which covers five months back pay¬ ments to date of loan, $150, interest $3.75, ex¬ pense of making loan, $18.25). This check I endorse and hand back to them. They then give me check for $2,828, net proceeds of loan, which I endorse to City Realty Co., this pay¬ ing interest of $62.07, and payment of $2,765.93 oh amount I owe them. All of these entries, or similar entries, have occurred in my practice, and are given here to show that COBB’S CASH- JOURNAL may be used to record any and all financial trans¬ actions of the professional man. Each page is totaled as indicated and footings carried for¬ ward until the end of the month. Inserts A, B and C are merely shown as memoranda, as A and C show on Summary form. B may be shown at the end of the month or on check stubs if used. S VYIN5 TOH-3ALt •p a C i ira u m - / C»,tft;‘u5 b7 COBB'S CASH JOURNAL WHITFIELD COBB, PUBLISHER winstoh-sauem. n. c.

This may be entered in the back of the Cash-Journal in a manner similar to the form shown. The form may be expanded or contracted to cover assets and liabilities of any volume. In these illustrations, small numbers are used purposely in most cases in order that the additions may be easily checked. These figures are also of value if the pro¬ fessional man wishes to make a summary and trial balance each month. See cuts marked “Summary and Cost Ledger Sheet ‘A’ ” and “Summary and Cost Ledger Sheet ‘B’. ” The “Figures on Opening Book ’ (Column 1) are taken from statement of Conditions of Finances First of Year.” The columns marked “Monthly Figures show the cost and other items for the month, while columns marked “Totals and Balances (also “Totals and Trial Balance”) show the to¬ tals and balances from the first of the year to the end of that particular month. (The figures in the second column each month may be written in red ink for contrast.) Cross additions are made on Sheet A on all lines except lines 1-3-5-29-32. The vertical additions of lines 6 to 21 show cost of practice. On Sheet B, cross additions are made on lines a-b-c-f-g-h-i-p-y. Other entries are as indicated. Where an item is put in parenthesis, this indicates that it is to be subtracted, not added. Red ink may be used instead to indicate this. Depreciation, bad debts and materials on hand are taken care of in closing entries at end of year, as indicated. In case the professional man tithes and wishes to keep track of his dues, this may be done as shown in brackets at bottom Sheet B. Of course a full double page should be allowed for each Summary Sheet and the column heads need then be written in o i the lines to the left only once to show a full year’s business. The “Total Debits” must balance the “Total Credits” each month, or an error has been made. Likewise “Balance Due Me From Practice End of Month”(Sheet A, line 5), must agree with total of ledger balances. TL' > is an automatic check on errors in bookkeeping, and such errors, if made, should be found and corrected. COBB’S CASH-JOURNAL may be used with any form of Ledger and any Appointment-Day Book which shows gross pract and cash practice for the day. It is designed for the use of physicians, dentists, occulists, lawyers, osteopaths, opticians—all p o fessional men depending upon fees, not, salary, for their income. Will be shipped by prepaid parcel post anywhere in the Unit..! States for $6.00, cash with order or C. O. D. Orders May Be Sent Direct to DR. WHITFIELD COBB, WINSTON-SALEM, N. C. COBB'S SYSTEM OF DENTAL BOOKKEEPING COBB’S SYSTEM OF DENTAL BOOKKEEPING, which is the development of ten years of dental practice, consists o Cobb’s Cash-Journal (which has been explained in the preceding pages), Cobb’s Ledger for Dentists and Cobb’s Appointment-Day Book for Dentists, and covers fully all the bookkeeping needs of the dentists in general practice. The books may be used separately or together. See illustrations showing specimen entries in Appointment-Day Book and Ledger, and trace related entries of March 31 and April 3. PROPERTY OF HIGH POINT PUBLIC LIBRARY HIGH POINT, NORTH CAROLINA These three books may be described briefly as follows: LEDGER—Loose leaf sheets are used in a binder of the simplest and most convenient form of construction. Each sheet has large, clear cuts of the teeth, temporary as well as permanent, on which intelligent drawing may be made of fillings. These sheets are ruled and printed on the front and ruled all across the back, giving about three times as much space for records as sheets ruled and printed on one side. There are columns for entering practical¬ ly every operation ordinarily met with in gen¬ eral practice, simply by inserting the number of the tooth and column for showing the time used, besides the usual ledger columns. Price $ 10 . 00 . APPOINTMENT-DAY BOOK—This is real- lv three books in one—a record of appoint¬ ments, a book for timing the operations and a record of daily operations, charges and cash practice. It has cuts of the teeth and columns for recording operations corresponding to those in Ledger, to facilitate posting The total time used, charge made, and cash practice for the day and for the month may be shown, enabling the dentist to realize what his productive time rv» n n o i n rv» ait 1^ mi a a Cv /A fl CASH-JOURNAL—This book is a cash book, journal and check register combined, and was designed with es¬ pecial reference to making Income Tax returns. Its proper use will show exactly xvhat practice is costing and profit. All receipts and all payments, whether by cash or check, are shown here, and distribution is made in columns to show the operating expense (with sub-di¬ visions), cost of equipment, amounts for personal use, credits to patients or clients, deposits and checks, in¬ vestments, donations, other income, etc. Price $6.00.
