Accounting Accountancy (UK), or accounting (US), is the production of financial records about an organization. Accountancy generally produces financial statements that show in money terms the economic resources under the control of management; selecting information that is relevant and representing it faithfully. The principles of accountancy are applied to accounting, bookkeeping, and auditing. Many tedious accounting practices have been simplified with the help of computer software. Enterprise resource planning (ERP) software provides a comprehensive, centralized, integrated source of information that companies can use to manage all major business processes, from purchasing to manufacturing to human resources. This software can replace up to 200 individual software programs that were previously used. Computer integrated manufacturing allows products to be made and completely untouched by human hands and can increase production by having less errors in manufacturing process. Computers have reduced the cost of accumulating, storing, and reporting managerial accounting information and have made it possible to produce a more detailed account of all data that is entered into any given system. Computers have changed business to business interaction through e-commerce. Rather than dealing with multiple companies to purchase products a business can purchase a product at a less expensive price and take out the third party and vastly reduces expenses companies once accrued. Inter-organizational information system enable suppliers and businesses to be connected at all times. When a company is low on a product the supplier will be notified and fulfill an order immediately which eliminates the need for someone to do inventory, fill out the proper documents, send them out and wait for their products. Accounting is thousands of years old; the earliest accounting records, which date back more than 7,000 years, were found in Mesopotamia (Assyrians). The people of that time relied on primitive accounting methods to record the growth of crops and herds. Accounting evolved, improving over the years and advancing as business advanced. Early accounts served mainly to assist the memory of the businessperson and the audience for the account was the proprietor or record keeper alone. Cruder forms of accounting were inadequate for the problems created by a business entity involving multiple investors, so double-entry bookkeeping first emerged in northern Italy in the 14th century, where trading ventures began to require more capital than a single individual was able to invest. The development of joint-stock companies created wider audiences for accounts, as investors without firsthand knowledge of their operations relied on accounts to provide the requisite information. This development resulted in a split of accounting systems for internal (i.e. management accounting) and external (i.e. financial accounting) purposes, and subsequently also in accounting and disclosure regulations and a growing need for independent attestation of external accounts by auditors. Today, accounting is called "the language of business" because it is the vehicle for reporting financial information about a business entity to many different groups of people. Accounting that concentrates on reporting to people inside the business entity is called management accounting and is used to provide information to employees, managers, owner-managers and auditors. Management accounting is concerned primarily with providing a basis for making management or operating decisions. Accounting that provides information to people outside the business entity is called financial accounting and provides information to present and potential shareholders, creditors such as banks or vendors, financial analysts, economists, and government agencies. Because these users have different needs, the presentation of financial accounts is very structured and subject to many more rules than management accounting. The body of rules that governs financial accounting in a given jurisdiction is called Generally Accepted Accounting Principles, or GAAP. Other rules include International Financial Reporting Standards, or IFRS, or US GAAP. Accounting in the Roman Empire The Res Gestae Divi Augusti (Latin: "The Deeds of the Divine Augustus") is a remarkable account to the Roman people of the Emperor Augustus' stewardship. It listed and quantified his public expenditure, which encompassed distributions to the people, grants of land or money to army veterans, subsidies to the aerarium (treasury), building of temples, religious offerings, and expenditures on theatrical shows and gladiatorial games. It was not an account of state revenue and expenditure, but was designed to demonstrate Augustus' munificence. The significance of the Res Gestae Divi Augusti from an accounting perspective lies in the fact that it illustrates that the executive authority had access to detailed financial information, covering a period of some forty years, which was still retrievable after the event. The scope of the accounting information at the emperor's disposal suggests that its purpose encompassed planning and decision-making. The Roman historians Suetonius and Cassius Dio record that in 23 BC, Augustus prepared a rationarium (account) which listed public revenues, the amounts of cash in the aerarium (treasury), in the provincial fisci (tax officials), and in the hands of the publicani (public contractors); and that it included the names of the freedmen and slaves from whom a detailed account could be obtained. The closeness of this information to the executive authority of the emperor is attested by Tacitus' statement that it was written out by Augustus himself. Roman writing tablet from the Vindolanda Roman fort of Hadrian's Wall, in Northumberland (1st-2nd century AD) requesting money to buy 5,000 measures of cereal used for brewing beer. Department of Prehistory and Europe, British Museum. Records of cash, commodities, and transactions were kept scrupulously by military personnel of the Roman army. An account of small cash sums received over a few days at the fort of Vindolanda circa 110 AD shows that the fort could compute revenues in cash on a daily basis, perhaps from sales of surplus supplies or goods manufactured in the camp, items dispensed to slaves such as cervesa (beer) and clavi caligares (nails for boots), as well as commodities bought by individual soldiers. The basic needs of the fort were met by a mixture of direct production, purchase and requisition; in one letter, a request for money to buy 5,000 modii (measures) of braces (a cereal used in brewing) shows that the fort bought provisions for a considerable number of people. The Heroninos Archive is the name given to a huge collection of papyrus documents, mostly letters, but also including a fair number of accounts, which come from Roman Egypt in 3rd century AD. The bulk of the documents relate to the running of a large, private estate is named after Heroninos because he was phrontistes (Koine Greek: manager) of the estate which had a complex and standarised system of accounting which was followed by all its local farm managers. Each administrator on each sub-division of the estate drew up his own little accounts, for the day-to-day running of the estate, payment of the workforce, production of crops, the sale of produce, the use of animals, and general expenditure on the staff. This information was then summarized as pieces of papyrus scroll into one big yearly account for each particular sub-division of the estate. Entries were arranged by sector, with cash expenses and gains extrapolated from all the different sectors. Accounts of this kind gave the owner the opportunity to take better economic decisions because the information was purposefully selected and arranged. Simple accounting is mentioned in the Christian Bible (New Testament) in the Book of Matthew, in the Parable of the Talents. Luca Pacioli and double-entry bookkeeping When medieval Europe moved to a monetary economy in the 13th century, sedentary merchants depended on bookkeeping to oversee multiple simultaneous transactions financed by bank loans. One important breakthrough took place around that time: the introduction of double-entry bookkeeping, which is defined as any bookkeeping system in which there was a debit and credit entry for each transaction, or for which the majority of transactions were intended to be of this form. The historical origin of the use of the words 'debit' and 'credit' in accounting goes back to the days of single-entry bookkeeping in which the chief objective was to keep track of amounts owed by customers (debtors) and amounts owed to creditors. 'Debit,' is Latin for 'he owes' and 'credit' Latin for 'he trusts'. The earliest extant evidence of full double-entry bookkeeping is the Farolfi ledger of 1299-1300. Giovanno Farolfi & Company were a firm of Florentine merchants whose head office was in Nîmes who also acted as moneylenders to the Archbishop of Arles, their most important customer. The oldest discovered record of a complete double-entry system is the Messari (Italian: Treasurer's) accounts of the city of Genoa in 1340. The Messari accounts contain debits and credits journalised in a bilateral form, and contain balances carried forward from the preceding year, and therefore enjoy general recognition as a double-entry system. Portrait of Luca Pacioli, attributed to Jacopo de' Barbari, 1495, (Museo di Capodimonte). Luca Pacioli's "Summa de Arithmetica, Geometria, Proportioni et Proportionalità" (early Italian: "Review of Arithmetic, Geometry, Ratio and Proportion") was first printed and published in Venice in 1494. It included a 27-page treatise on bookkeeping, "Particularis de Computis et Scripturis" (Latin: "Details of Calculation and Recording"). It was written primarily for, and sold mainly to, merchants who used the book as a reference text, as a source of pleasure from the mathematical puzzles it contained, and to aid the education of their sons. It represents the first known printed treatise on bookkeeping; and it is widely believed to be the forerunner of modern bookkeeping practice. In Summa Arithmetica, Pacioli introduced symbols for plus and minus for the first time in a printed book, symbols that became standard notation in Italian Renaissance mathematics. Summa Arithmetica was also the first known book printed in Italy to contain algebra. Although Luca Pacioli did not invent double-entry bookkeeping, his 27-page treatise on bookkeeping contained the first known published work on that topic, and is said to have laid the foundation for double-entry bookkeeping as it is practiced today. Even though Pacioli's treatise exhibits almost no originality, it is generally considered as an important work, mainly because of its wide circulation, it was written in the vernacular Italian language, and it was a printed book. According to Pacioli, accounting is an ad hoc ordering system devised by the merchant. Its regular use provides the merchant with continued information about his business, and allows him to evaluate how things are going and to act accordingly. Pacioli recommends the Venetian method of double-entry bookkeeping above all others. Three major books of account are at the direct basis of this system: the memoriale (Italian: memorandum), the giornale (Journal), and the quaderno (ledger). The ledger is considered as the central one and is accompanied by an alphabetical index. Pacioli's treatise gave instructions in how to record barter transactions and transactions in a variety of currencies – both of which were far more common than they are today. It also enabled merchants to audit their own books and to ensure that the entries in the accounting records made by their bookkeepers complied with the method he described. Without such a system, all merchants who did not maintain their own records were at greater risk of theft by their employees and agents: it is not by accident that the first and last items described in his treatise concern maintenance of an accurate inventory. The nature of double-entry can be grasped by recognizing that this system of bookkeeping did not simply record the things merchants traded so that they could keep track of assets or calculate profits and losses; instead as a system of writing, double-entry produced effects that exceeded transcription and calculation. One of its social effects was to proclaim the honesty of merchants as a group; one of its epistemological effects was to make its formal precision based on a rule bound system of arithmetic seem to guarantee the accuracy of the details it recorded. Even though the information recorded in the books of account was not necessarily accurate, the combination of the double entry system's precision and the normalizing effect that precision tended to create, produced the impression that books of account were not only precise, but accurate as well. Instead of gaining prestige from numbers, double entry bookkeeping helped confer cultural authority on numbers.
