What is Bookkeeping for Small Business?

Bookkeeping is the systematic recording, organising, and tracking of a business's financial transactions. These transactions include sales, purchases, receipts, and payments made by an individual or organisation.

Why is it important?

1. Financial Health Tracking – Know exactly where your money is coming from and where it's going.
2. Tax Compliance – Ensure you're meeting ATO reporting obligations and can claim eligible deductions.
3. Cash Flow Management – Identify cash gaps before they become a problem.
4. Decision Making – Use reliable data to grow and sustain your business.

Bookkeeping vs Accounting

Bookkeeping is the first step in the financial reporting process. Accountants use bookkeeping data to provide insights, prepare tax returns, and create financial statements.

How to Do Bookkeeping for Small Business in Excel

While many businesses use platforms like Xero or MYOB, Microsoft Excel remains a popular starting point for small businesses due to its low cost and simplicity.

Step-by-Step Excel Bookkeeping Process

1. Set Up Your Spreadsheet
   • Create columns for: Date, Description, Reference/Invoice Number, Income, Expense, GST, and Account Category.
2. Track All Transactions
   • Enter daily or weekly financial activity from bank statements or receipts.
3. Categorise Transactions
   • Use common categories like Sales, Rent, Utilities, Advertising, Salaries, etc.
4. Add GST Columns
   • Include a column to record GST paid or collected. This is crucial for BAS reporting.
5. Create Summary Tabs
   • Use formulas to summarise monthly income, expenses, and profit/loss.
6. Reconcile Regularly
   • Compare your Excel entries with your bank statements to ensure accuracy.

Pros & Cons of Excel Bookkeeping

Pros:

• Low cost
• Easy to customise
• Great for businesses with low transaction volumes

Cons:

• Manual entry can lead to errors
• No automation or real-time insights
• Limited scalability

How to Do Simple Bookkeeping for Small Business

You don’t need to be a financial expert to manage basic bookkeeping. Here’s how to keep it simple and effective:

1. Separate Business & Personal Finances

Open a separate bank account for your business. This avoids confusion and helps with accurate reporting.

2. Use the Right Tools

Start with Excel or use cloud software like Xero or MYOB. Trinity Accounting Practice recommends Xero for its ease of use and powerful automation features.

3. Keep All Receipts

Whether digital or paper, receipts are vital for tax deductions and audits.

4. Record Transactions Regularly

Don’t wait until the end of the quarter. Allocate 15-30 minutes a week to stay updated.

5. Track GST (if registered)

Ensure your invoices include GST and you are keeping track of GST paid on expenses for BAS reporting.

6. Review Reports Monthly

At a minimum, look at your:

• Profit & Loss Statement
• Balance Sheet
• Cash Flow Report

🧾 Trinity can prepare these reports for you monthly or quarterly to help you stay in control.
