The accounting cycle: from transaction to financial statement

The accounting cycle: from transaction to financial statement

The accounting of a business is not a loose list of notes that pile up without order. It is a circuit that repeats every month and every year, following the same sequence of steps: first the transactions happen, then they are backed by documents, then they are recorded in the books, later they are corrected with adjustments, and finally they become the financial statements. That complete journey is called the accounting cycle, and understanding it as a map is the best way to study accounting: every lesson in this manual develops one stop of the journey, and this lesson shows the whole route so you always know where you are along the way.

Think of the cycle as the work routine that the business repeats every accounting period. The most common period is the month: the business buys, sells, spends and collects during thirty days, and at the end of that month it needs to know how much it earned and what it owns. Accounting exists to answer those two questions in an orderly way, and the accounting cycle is the method that makes it happen. If you master the map, every new topic you study afterwards will have a place to fit: it stops being an isolated fact and becomes a stage of a process you already know.

The map of the course: six stops that repeat

The accounting cycle of any business, no matter how small, has six stops. It is worth memorizing them in order, because that order is the backbone of the whole accounting manual:

• Business transactions: purchases, sales, expenses and payments that happen in the reality of every day.
• Source documents: the invoice, receipt or voucher that leaves a written trace of each transaction.
• Recording in the books: the journal entries and the movement of every account in the ledger.
• End-of-period adjustments: the physical inventory count, depreciation and provisions that bring balances up to date.
• Financial statements: the income statement and the balance sheet that summarize the period.
• Closing and the new period: the result is determined, the accounts are closed and the cycle starts again.

The six stops are always traveled in that order, and when the sixth one is reached the cycle begins again. That is why it is called a cycle and not a path: it is a wheel that turns every month. The rest of the lessons in this course do nothing but stop at each station and explain it in detail; this lesson is the overall plan that gives them meaning.

Stop 1: the business transactions

Every accounting cycle is born in reality, not in the books. A customer walks into the store and buys merchandise; the business orders new merchandise from the supplier; the rent of the location is paid; a supplier receives a payment; an employee receives a salary. Those events are called transactions, and they are the raw material of accounting. Without transactions there is nothing to record, so the first stage of the cycle is simply recognizing that they happened and understanding what kind of event each one is: a purchase, a sale, an expense or a payment.

Living with orderly accounting does not require writing down every movement at the exact moment, but it does require knowing how to tell the types of transaction apart: buying merchandise increases what the business has to sell; selling reduces it and at the same time creates the revenue; an expense consumes value without creating stock; a payment moves money out of the cash drawer or the bank account. The purchasing, sales and treasury lessons of this manual explain each type with its entries; here it is enough to recognize them as the starting point of the wheel.

Stop 2: the source document, the written trace of every event

A transaction that leaves no document is a transaction that accounting cannot prove. The second stop of the cycle is the source document: the purchase or sales invoice, the cash receipt, the payment voucher, the credit note. Each document provides the data that will later feed the books: date, parties involved, description, quantities and amounts. The lesson on source documents in this manual explains what information each one carries and why the accountant and the owner must keep them in order.

The practical rule is simple: no record without a source document. If the business pays the rent and does not keep the receipt, that expense has no support and accounting cannot include it with confidence. The habit of filing documents by date and by type is what turns accounting into a verifiable story of the business, and it is also the foundation of the third stop, because journal entries are built from what the papers say.

Stop 3: recording in the journal and in the ledger

With the source document in hand, it is time to record. Accounting writes down each transaction twice: first in the general journal, where events are written in date order as entries, and then in the ledger, where each account accumulates its own movements. The entry follows the double-entry rule studied in the first lessons of the course: every record touches at least two accounts, one that receives and one that gives, which is why the system never goes out of balance when it is done properly. The chart of accounts, also from the early lessons, is the common language that makes it possible to code every movement.

This stop is home to the most operational lessons of the manual: the accounting record of inventory purchases, the record of sales with its double effect on revenue and on cost, the handling of cash, bank operations and the bank reconciliation. They all share the same mechanics: take the document, identify the affected accounts according to the chart of accounts, and write the entry in the journal so the ledger shows the new balance. At the end of the month, if every transaction of the period was recorded, the books tell the complete story of what happened; if one was left out, the story is incomplete even though nobody notices it yet.

Stop 4: the adjustments that bring balances up to date

Recording everything that happened is not enough, because some events of the period arrive without an invoice and are invisible in the day-to-day routine. The fourth stop of the cycle is the end-of-period adjustments, and in a business with inventory the most important one is the stock adjustment. During the month merchandise was sold, products were returned, and perhaps there were losses or damages; the value that the books show as inventory must be checked against the reality of the warehouse. The physical count on the last day of the period and its comparison with what the records say is one of the central tasks of this manual, together with the determination of the ending inventory and the cost of goods sold.

Adjustments do not end with inventory. Fixed assets are also adjusted with the depreciation of the period, because the shelving or the vehicle wears out even though nobody pays for that wear and tear; and provisions are set up, such as the allowance for doubtful accounts receivable, so that balances do not promise more than what will actually be collected. Each of these topics has its own lesson later in the course: the logic is common, recognizing that the book and the reality drifted apart during the month and bringing them back together with adjusting entries before looking at the results.

Stop 5: the financial statements tell the result

When the books are complete and adjusted, the business can finally ask them what it needs to know. The fifth stop of the cycle produces the two great reports: the income statement, which answers how much the business earned or lost in the period, subtracting the cost of the merchandise sold and the expenses from sales; and the balance sheet, which answers what the business owns and owes at that moment, showing inventory as one of its main assets. The lessons in this manual devoted to each statement explain their structure with numerical examples from a trading business.

It is worth pausing on an idea that appears over and over in this course: the profit on the income statement is not the same as the money in the cash drawer. A business can show a profit and still run out of cash, because purchased merchandise ties up money while it waits to be sold and credit sales are collected weeks later. The accounting cycle shows that phenomenon clearly: the result is calculated on an accrual basis, while cash follows its own rhythm. That is why reading the statements also includes comparing profit with cash flow, a topic with its own lesson in the final stretch of the manual.

Stop 6: the closing and the next turn of the wheel

The sixth stop puts the house in order to start again. In the accounting closing, the results of the period are determined, the revenue and expense accounts are closed so their balance moves into equity, and the ending inventory is defined, since it will become the beginning inventory of the following month. When the cycle closes, every income statement account returns to zero and the new period starts with the correct balances of assets, liabilities and equity. The closing lesson of this manual develops that step by step with its entry mechanics.

The cycle, then, never really ends: one turn ends and the next one begins. The ending inventory of this month is the beginning inventory of the next, the outstanding accounts receivable continue their course, and the business buys, sells, adjusts and reports again. That continuity is the reason accounting is taught as a cycle: whoever understands the wheel understands that no record is an isolated event, but a movement inside a process repeated with discipline month after month.

Table 1: who performs each stage of the cycle

The accounting cycle is not executed by a single person. In a small business, the owner takes part, living the transactions and providing the documents; the accountant takes part, reviewing, adjusting and signing the statements; and the information system takes part, organizing the daily record. The following table summarizes each stage, what happens in it and the lesson of this course that develops it in detail.

Notice that the owner never disappears from the cycle: even when a program such as Kardex Tauro makes the records and organizes the documents, the transaction is born in the operation and the physical count happens in the warehouse, with real people. The system frees the owner from repetitive work, but the judgment about what actually happened in the business remains human.

Table 2: a full month in a small business

To see the cycle working, let us follow a month of a small business that sells merchandise. Every event on the calendar lands on a stage of the cycle, and the following table shows the complete journey, from the purchase on day 1 to the report on day 30.

Review the day 5 row and you will see the essence of a business with inventory: the sale does not only bring cash and revenue, it also takes merchandise out of the warehouse at its cost, and that cost is what the income statement subtracts from sales at the end of the month. The day 28 row shows why the count is essential: if during the month there were losses, returns or errors, only the comparison between the real warehouse and the books makes it possible to adjust the inventory before reporting.

Inventory, the silent protagonist of the cycle

In a trading business, almost every stop of the cycle revolves around the same protagonist: inventory. The purchase increases it, the stock keeps it, the sale decreases it and generates the cost of goods sold, the count verifies it and the adjustment corrects it. That chain, purchase, stock, sale, cost, count and adjustment, crosses the cycle from end to end and reappears in every lesson of the manual that touches merchandise. Whoever has it clear will understand why inventory appears so many times in the financial statements and why neglecting it throws the profit of the business out of balance without anyone noticing.

The practical recommendation of this lesson is simple: adopt the cycle calendar as a routine. Record the documents every week, reserve the last day of the month for the physical count and the adjustments, and the first days of the following month for reviewing the statements with your accountant. The result of that discipline is that the business never reaches the end of the month without knowing how much it earned, what it owns and what it owes.

This was the bird's-eye view of the accounting cycle: six stops that repeat every period, from the transaction to the financial statement and the closing. The following lessons of this manual go down to each stop with its rules, its entries and its numerical examples. Tools such as Kardex Tauro make the journey easier by organizing records, documents and stock cards, but the map you learned today is what lets you understand what is happening at every moment of the wheel. Keep the map: it is the compass of the whole course.
