Accounting Methods
Tally sticks were the earliest type of loan accounting. A stick that could
be split was carefully notched to show the sum being borrowed by a mer-
chant or a government. The notches were wide enough to go well across
the stick; the stick was split down the middle so both halves showed the
marks of the notches. The lender kept the larger piece, called the stock, and
the borrower kept the shorter piece.
Another way of counting sums, a sort of manual cash register, was the
counting-board, called the exchequer. It was a wooden platter with a rim
around it, covered with linen and chalked off into a chessboard pattern.
Coins, or coin stand-ins called jetons, could be added in columns. On a
French counting-board at a large Champagne fair, there was a column for
the smallest unit of money, the heller. The next column stood for sous, and
then pounds, 20 pounds, 100 pounds, and 1,000 pounds.
During the 13th and 14th centuries, Italian companies developed new
methods of accounting. Merchants had always kept track of money received
or paid. The original, primitive method of making notches or marks on a
stick had given way to paper books, but the entries were written in a sin-
gle column. Although an accountant could use the record to calculate the
business’s value at any time, it was diffi cult to sort the types of entries. By en-
tering debits and credits in separate columns, an accountant could keep a
running sum of the business’s capital on hand and its value in purchased
supplies. At fi rst, these entries were kept on facing pages—a system devel-
oped in Venice. Gradually, the entries were kept on the same page using a
double column, the way simple accounting is done today.
During the 14th century, accountants converted to the Arabic numeral
system used in modern times. Some Italian merchants had converted to
Arabic accounting as early as the 12th century because they had warehouses
in North Africa. Leonardo of Pisa, known as Fibonacci, learned account-
ing with Arabic numerals in the late 12th century by working at the family’s
warehouse in Bougia, North Africa. However, Italian city governments were
afraid the new numbers were easier to doctor in account books, and they
outlawed them around 1300. By 1400, many accountants were using them
anyway, and by 1500, they were universally adopted.
