What Is a Chart of Accounts?

Textbook Definition

A chart of accounts is an organized listing of all accounts used in a business's general ledger, typically grouped into assets, liabilities, equity, revenue, and expenses, with each transaction posted to one account.

In Plain English

A chart of accounts is a short list of named drawers for your money. Kinds of money coming in, kinds of money going out. Every line in your books goes in exactly one drawer, so you can total any drawer in a minute.

Why Does One Big Category Hide Problems?

A ledger with one category is a list, not a set of books. It can tell you what happened on Tuesday. It cannot tell you how much you spent on wages this year, or which service actually makes money. Those are questions about kinds of things, and you can only answer them if every line has a kind.

The money-in drawers are your revenue, split by what customers pay you for. The money-out drawers are your expenses, split by what you pay for. Every chart needs one "everything else" drawer. The rule is that it stays the smallest one.

Signs you have this problem:

  • Miscellaneous or "Other" is one of your biggest lines.
  • You cannot say what you spent on one cost, like fuel or supplies, without going line by line.
  • You do not know which of your services or products makes the most money.
  • Your categories change from month to month.
  • Your chart has fifty categories and you stopped using it.
  • Your bookkeeper asks what something was for, every month.
If you cannot total a kind of cost in under a minute, the books are kept but not organized. A short list of drawers fixes that.

What It Looks Like When Everything Is Miscellaneous

From the Fabled Forest · Chapter 3

Otto the Octopus learned to keep a ledger, and his turtle, Tobias, writes every line in perfect handwriting. Six months of deliveries, parcels, rentals, tape, and wages, all in order. Every single line is filed under Miscellaneous.

When the bookkeeper asked which of Otto's four services made the most money, Otto said rentals. Everybody rents his carts. How did he know? Because he was always fixing them.

Doctor Owl built him a chart with four kinds of money in, six kinds out, and one small "everything else." Tobias recoded a month. Rentals brought in fourteen coins. Cart repairs cost nineteen. Otto's favorite part of the business had lost money five months out of six, and the boring deliveries had been paying for everything.

Otto's story is Chapter 3 of Accounting and Finance for Small Businesses, Book 2 of Dr. Paul's Fabled Forest Business School Series.

How to Build a Simple Chart of Accounts in 5 Steps

Most owners who sit down to do this write a hundred categories. Aim for about twelve.

  1. List what customers pay you for.

    Three to five kinds of revenue. Deliveries, repairs, product sales, rentals. Split them by the way you would want to compare them later.

  2. List what you pay for.

    Six to eight kinds of expenses: wages, rent, supplies, fuel, materials, repairs, marketing. Ask of every cost: is this a different kind, or the same kind in a different size? Tape and boxes are both packing supplies.

  3. Add one "everything else" drawer.

    Every chart needs one. Keep it the smallest. If it ever grows, you have found a category you forgot to name.

  4. Recode last month.

    Go back through one month of your ledger and give every line one name from the list. Then total each drawer. This is where the surprises live.

  5. Use the same list every month.

    Do not invent new drawers on the fly. Consistency is what lets you compare this month to last month and this year to last year.

Dr. Paul's Insight

The classic mistake is building a chart that matches your accounting software's default list of eighty accounts. You will not use it, and you will end up dumping things in Other. Start with a dozen drawers that match how you think about your business. Your accountant can map them to the formal account types later. The goal is a list you can read without help.

Worked Example: One Category, Recoded Rentals bring in $1,400 a month. It feels like your best service. Rental repairs cost $1,900 a month. Rentals lose $500 every month. Raise the rental price by $10 on about 80 rentals and add a damage fee that covers about $300 of repairs. 80 × $10 = $800, plus $300 = $1,100 a month better. Rentals move from minus $500 to plus $600, found by naming one drawer. Figures are an illustration to show the math, not a projection for your business.

Which Service Really Makes the Money?

Chapter 3 · Chart of Accounts

Everything Is Miscellaneous: An Octopus's Ledger

"You deliver, you pack and ship, you handle mail, and you rent carts and handcarts. Four kinds of work. Which one makes you the most coins?"

Otto brightened. "Rentals. Easy. Everybody rents something. Half the forest has one of my handcarts right now."

"How do you know?"

"Because I'm always fixing them."

Barnaby closed the ledger gently.

"That is not what I asked," he said.

Chart of Accounts Questions

What is an example of a chart of accounts?
A simple one for a service business might list revenue drawers like deliveries, repairs, and rentals, and expense drawers like wages, rent, supplies, fuel, repairs, insurance, marketing, and one small everything-else line. Every transaction in the ledger gets one name from that list.
How many accounts should a small business have?
Fewer than you think. About a dozen is plenty to start: three to five kinds of revenue, six to eight kinds of expenses, and one catch-all. A chart with dozens of accounts usually gets abandoned, and everything ends up dumped in Other.
What are the main types of accounts?
Formal charts group accounts into five types: assets, liabilities, equity, revenue, and expenses. For day-to-day tracking, most owners start with the last two, kinds of money in and kinds of money out, and let their accountant map them to the full structure for statements and taxes.
Is it bad to use a miscellaneous account?
No, every chart needs one. The rule is to keep it the smallest line. If miscellaneous grows large, it is hiding a real kind of cost you have not named yet. Pull those lines out, give them their own category, and you will start seeing where the money goes.
