How to Do Accounting for Your Small Business (Step-by-Step)

So you've started a small business and now you need to "do accounting." But what does that actually mean in practice? What do you literally need to do, step by step?

This tutorial gives you exactly that—a practical, step-by-step guide to handling your small business accounting. Follow these steps, and you'll have organized books that keep you informed and tax-ready.

Before You Start: What You'll Need

Gather these items before beginning:

Gather these items before beginning:

• Business bank account login credentials
• Any existing receipts and invoices
• Your business registration documents (for reference)
• Accounting software or a spreadsheet template
• A dedicated folder for storing receipts (digital is fine)

Step 1: Choose Your Accounting Method

You need to decide between cash and accrual accounting:

You need to decide between cash and accrual accounting:

Cash Accounting

• Record income when you receive payment
• Record expenses when you pay them
• Best for: Most small businesses, especially service-based
• Advantage: Simpler, matches your bank account

Accrual Accounting

• Record income when you invoice (before payment)
• Record expenses when you receive bills (before paying)
• Best for: Larger businesses, those with inventory
• Advantage: More accurate picture of business performance

Recommendation: Start with cash accounting unless you have a specific reason not to.

Step 2: Set Up Your Chart of Accounts

A chart of accounts is your list of categories for organizing transactions.

A chart of accounts is your list of categories for organizing transactions. At minimum, include:

Income Categories

• Product Sales
• Service Revenue
• Other Income (interest, etc.)

Expense Categories

• Cost of Goods Sold (if applicable)
• Rent/Lease
• Utilities
• Office Supplies
• Software/Subscriptions
• Marketing/Advertising
• Professional Services
• Travel
• Insurance
• Bank Fees

You can add more categories as needed, but don't overcomplicate it. Too many categories makes bookkeeping tedious.

Step 3: Record Every Transaction

This is the core of accounting—recording what comes in and goes out.

This is the core of accounting—recording what comes in and goes out.

For Income

When you receive payment, record:

1. Date received
2. Amount
3. Customer name
4. What it was for
5. Invoice number (if applicable)

If you use invoicing software, income is tracked automatically when you mark invoices as paid.

For Expenses

When you spend money, record:

1. Date of purchase
2. Amount
3. Vendor/merchant
4. Category
5. Business purpose

Save the receipt! A phone photo to a dedicated folder works well.

Step 4: Reconcile Your Accounts Monthly

Reconciliation means comparing your records to your bank statement.

Reconciliation means comparing your records to your bank statement. Here's how:

1. Get your bank statement for the month
2. Compare each transaction to your records
3. Check off matching items
4. Investigate any differences
5. Add any transactions you missed
6. Verify your ending balance matches the bank

Reconciliation catches errors, fraud, and forgotten transactions. Do it monthly without fail.

Step 5: Generate Basic Financial Reports

Good accounting produces useful reports.

Good accounting produces useful reports. Create these monthly:

Profit and Loss Statement (Income Statement)

Shows revenue, expenses, and profit for a period. Answers: "Did I make money this month?"

Format:

• Total Revenue
• Minus: Cost of Goods Sold
• Equals: Gross Profit
• Minus: Operating Expenses
• Equals: Net Profit

Cash Flow Summary

Shows money in vs. money out. Answers: "What happened to my cash?"

Format:

• Starting Cash Balance
• Plus: Cash Received
• Minus: Cash Spent
• Equals: Ending Cash Balance

Step 6: Prepare for Taxes Throughout the Year

Don't wait until tax time.

Don't wait until tax time. Throughout the year:

• Set aside tax money: Transfer 25-30% of profit to a separate savings account
• Track deductible expenses: Ensure they're properly categorized with receipts
• Make quarterly payments: If required, pay estimated taxes each quarter
• Keep organized records: Everything in its place, easy to find

Step 7: Review and Analyze Monthly

Accounting isn't just record-keeping—it's decision-making.

Accounting isn't just record-keeping—it's decision-making. Monthly, ask yourself:

• Is revenue trending up or down?
• Are any expense categories growing unexpectedly?
• What's my profit margin? Is it healthy?
• Do I have enough cash to cover upcoming expenses?
• Which clients or products are most profitable?

These insights help you make better business decisions.

Weekly Accounting Routine

Set aside 30 minutes weekly for these tasks:
