Chart of Accounts (COA)

 

✅ 1️⃣ What is Chart of Accounts?

Chart of Accounts (COA) =  👉 List of all financial accounts of a company.

Simple meaning:

It is the structure of your accounting system.

Every financial transaction (Sales, Purchase, Expense, Bank, etc.) is posted into one of these accounts.


✅ 2️⃣ Why COA is Important?

Because:

• All accounting entries go to COA
• Profit & Loss is based on COA
• Balance Sheet is based on COA
• Reporting depends on COA structure

If COA is wrong → Financial reports will be wrong.


✅ 3️⃣ Types of Accounts in COA

COA is divided into 5 main groups:


🔵 1. Assets

What company owns.

Examples:
• Cash
• Bank
• Inventory
• Fixed Assets
• Accounts Receivable


🟢 2. Liabilities

What company owes.

Examples:
• Accounts Payable
• Loans
• Taxes Payable


🟡 3. Equity

Owner’s investment.

Examples:
• Capital
• Retained Earnings


🟣 4. Income (Revenue)

Money company earns.

Examples:
• Sales Revenue
• Service Income


🔴 5. Expenses

Company costs.

Examples:
• Salary Expense
• Rent Expense
• Electricity
• Purchase Cost


✅ 4️⃣ Structure of COA in Business Central

In Business Central, each account has:

• No. (Account Number)
• Name
• Account Type
• Income/Balance Type
• Posting Type
• Direct Posting
• Gen. Posting Type
• VAT Setup
• Dimensions


Let’s explain important fields 👇


🔹 Account No.

Example:
1000 – Cash
2000 – Accounts Payable
4000 – Sales

This number helps structure accounts.

Normally:
1000–1999 → Assets
2000–2999 → Liabilities
3000–3999 → Equity
4000–4999 → Revenue/Income
5000–5999 → Expenses


🔹 Account Type

Types:

• Posting
• Heading
• Total
• Begin Total
• End Total


Posting

Real account where entries are posted.

Example:
Bank Account


Heading

Used only for grouping.
No posting allowed.

Example:
"Current Assets"


Total

Used to show total of multiple accounts.


🔹 Income/Balance

Two options:

• Balance Sheet
• Income Statement

Balance Sheet → Assets, Liabilities, Equity
Income Statement → Income & Expenses


🔹 Direct Posting

If:
✔ Enabled → You can post directly to this account
❌ Disabled → Posting only through subledger

Example:
Accounts Receivable
Direct Posting = No
Because posting happens through Customer module.


🔹 General Posting Type

Defines account behavior:

• Purchase
• Sale
• Settlement

Helps system decide posting automatically.


✅ 5️⃣ How COA Works in Real Life

Example:

You sell goods worth ₹10,000.

System posts:

Dr Customer (Asset)
Cr Sales (Income)

Both accounts come from COA.


Example 2:

You purchase goods ₹5,000.

Dr Purchase Expense
Cr Vendor

All accounts come from COA.


✅ 6️⃣ COA & Posting Groups (Very Important)

Business Central does not manually select G/L accounts every time.

It uses:

• Customer Posting Group
• Vendor Posting Group
• Gen. Posting Setup
• Inventory Posting Setup

These connect:
Sales → Revenue Account
Purchase → Expense Account
Inventory → Inventory Account

All these accounts are defined in COA.



✅ 9️⃣ COA in Financial Reporting

COA is used in:

• Trial Balance
• Balance Sheet
• Profit & Loss
• Account Schedule
• Financial Statements

Everything depends on COA.


🔥 Final Simple Definition

Chart of Accounts =
The backbone of accounting system.

Every rupee posted in system goes to one account in COA.

Without COA → No accounting.
