3. How to Start Bookkeeping for a Small Business (Step-by-Step)?

I’ve received so many queries on “How to start bookkeeping for a small business?” and some of you directly asked guidance on “How do I do bookkeeping for a small business?”

So, I’ll answer it here clearly for you.

Step 1: Separate Business and Personal Finances

First step to small business bookkeeping is opening a dedicated business bank account. Never mix personal spending with business expenses, I said NEVER! This one step alone makes bookkeeping 10 times easier.

Step 2: Choose a Bookkeeping Method

There are two main methods:

Cash basis: You record income when money hits your bank.
Accrual basis: You record income when you send the invoice.

Usually, small businesses start with cash basis because it’s simpler, but it varies from business to business. Therefore, it is recommended to ask your accountant to suggest what fits your situation.

Step 3: Set Up Categories

The next important step is to create simple categories like:

• Sales

• Office supplies

• Marketing

• Travel

• Software subscriptions

• Utilities

Categories help you understand where money goes and you can customize your business categories based on requirements.

Step 4: Track Income

The very next and crucial step in small business bookkeeping is tracking your income. Every time you get paid, try to make sure that you do the following steps:

• Record the amount

• Add the date

• Include the customer name

• Mark VAT if applicable

The important advice here is, don’t rely only on your bank statement and be organized to avoid future penalties.

Step 5: Track Expenses

This is also one of the crucial step of bookkeeping, that should be tracked for every single detail. Make sure to keep every receipt.

For that, you can:

• Take photos and save on drive separately

• Upload digital copies

• Store them in folders

Also, the key tip here is, if it’s a business expense, record it immediately. Because, waiting leads to forgotten details.

Step 6: Reconcile Bank Accounts

Always try to compare your bookkeeping records and your actual bank statement at least once in a month. And make sure they match.

This step catches errors early without creating huge mess.

Step 7: Review Monthly Reports

The last and the careful step for small business bookkeeping is to review the following checklist at the end of each month:

• Profit and loss summary

• Expense breakdown

• Cash balance

This helps you spot patterns.

If you’re wondering how to do bookkeeping for small business properly, follow these steps at your earliest convenience to avoid inconsistent cash flow record in future. Keep track of your bookkeeping and don’t skip it at any cost.

Use Software Tutorials

Most bookkeeping software for small business includes guided setup that shows:

Also, learning inside the tool makes it practical and easier to understand.

Hire Help If Needed

5. Excel vs Bookkeeping Software

Many businesses start with Excel, because, it feels free and simple. But as you grow, it becomes risky.

The Problem with Excel usually are

• Manual errors: One wrong formula can ruin everything.

• No automation: You must enter everything yourself.

• No real-time reports: You build reports manually.

• VAT mistakes: Especially for bookkeeping for small business Ireland, VAT tracking in Excel can become messy fast.

• Hard to scale: More transactions mean more complexity. Spreadsheets work at the very beginning.

In short, excel isn’t designed specifically to handle today’s world cash flow with lots of complexities. I strongly believe in “modern days’ problem requires modern days’ solution”. And modern days’ solution of tracking business cash flow is bookkeeping soft wares.

Why Bookkeeping Software Is Better

Modern bookkeeping software for small business is designed to make life easier.
