I work with new business owners all the time. Most of them have the same tension: they're juggling setup, making their first sales, hiring their first people, and managing a hundred other things. And then someone tells them they need to set up an accounting system, and their eyes glaze over.
Here's what I tell them: bookkeeping isn't a side task. It's the foundation that lets you actually know how your business is doing. And the good news? You don't need it to be complicated. You just need it to be set up right from day one.
The three non-negotiable things for a new business
1. A dedicated business bank account
This is step one. Before you set up any accounting software, before you sort out GST registration, before anything else — open a separate bank account for your business.
Why? Because mixing personal and business money is a nightmare. Your bookkeeper can't reconcile it cleanly. Your accountant will have a harder time. And when you go to claim deductions or prove business income, you'll be scrambling.
Use the business account for every single business transaction, and keep your personal spending in your personal account. It takes five minutes to set up and saves you hundreds of hours later.
2. An accounting system (Xero, or similar)
You have two choices: you can use cloud-based accounting software like Xero, or you can use spreadsheets and wait until tax time to sort everything out.
I'm not going to pretend spreadsheets don't work — they do, technically. But they're slow, error-prone, and they don't talk to your bank or your accountant. Xero costs about $20–30 a month, and it literally saves you days of work every quarter when BAS time comes around.
Set up your Chart of Accounts early (that's the list of all your income and expense categories). Your accountant will usually help you with this, or your bookkeeper can. Get it right at the start, and your numbers are clean for life.
💡 Pro tip: Don't try to be too clever with your Chart of Accounts. Keep it simple. You need income, cost of goods sold, expenses (categorised sensibly), and assets/liabilities. That's it. You can refine it later, but simple is better than perfect when you're starting out.
3. A process for keeping your books updated
This is where new business owners go wrong. They set up Xero, feel good about themselves, and then nothing gets recorded for six weeks. Then tax time comes and it's chaos.
You need a rhythm. For most new businesses, that means:
- Recording invoices and expenses as they happen (or at least weekly)
- Reconciling your bank account once a month
- Checking your GST liability before the BAS is due
This doesn't take long — maybe 1–2 hours a month if you're doing it yourself. But it has to happen regularly. The worst time to "catch up" on six months of bookkeeping is when your BAS deadline is looming.
The extra things that matter as you grow
BAS registration and GST
If your turnover is over the GST threshold ($75,000 annually for most businesses), you need to register for GST. Once you do, you'll lodge a BAS — either quarterly, monthly, or annually depending on your turnover.
This isn't optional. It's a legal requirement. And if you've got the right bookkeeping system, it's straightforward. If you don't? It becomes a scramble every three months.
Set aside a GST holding account (a separate bank account) from day one if you know you'll be GST-registered. Every time you invoice a customer, put the GST portion into that account. When your BAS is due, the money is already sitting there waiting.
Payroll (if you're hiring)
If you're planning to hire employees (not contractors, but employees), you need a payroll system. This is non-negotiable. You need to pay superannuation, manage tax withholding, and lodge your Single Touch Payroll with the ATO every pay run.
Again, this isn't something to DIY unless you really understand the rules. The penalties for getting it wrong — missed super, incorrect PAYG withholding, missed STP submissions — are not small.
⚠️ Important: Having an ABN doesn't automatically make someone a contractor. That's a separate (and complex) decision, and it affects super, tax, workers comp, and your legal obligations. Get it right from the start. This is something to ask your bookkeeper or accountant about.
What you should do right now
If you're launching a new business or ramping up a side gig, here's your action list:
- Open a business bank account. This week. Seriously.
- Sign up for cloud accounting software (Xero is our go-to, but QuickBooks also works). Spend an hour setting up your Chart of Accounts — it doesn't need to be perfect, just sensible.
- Check your GST threshold. Will you need to register? If yes, do it early. You can register even if you're not yet at the threshold.
- Book a conversation with a bookkeeper or accountant. Not to hand everything over (unless you want to), but to get your setup right from day one. This one conversation saves you months of stress.
Why bookkeeping matters for new businesses (really matters)
Here's the honest truth: the difference between a business owner who knows exactly how much profit they're making and one who's flying blind is huge. I'm not just talking about tax time. I'm talking about:
- Knowing which projects are actually profitable
- Knowing when you're genuinely safe to hire or take time off
- Being able to get a loan if you need cash to grow
- Understanding your cash flow so you're never caught short
- Having clean books so tax time is straightforward instead of stressful
The businesses I see do well aren't necessarily the ones making the most money. They're the ones who have their act together. And that usually comes down to clean bookkeeping from day one.
You're building something exciting. The last thing you want is for bookkeeping to become a blockers to that growth. Get the foundations right now, and you'll have months of breathing room later.
Common questions
What bookkeeping do I need to set up when starting a business?
Three things are non-negotiable: a dedicated business bank account, cloud accounting software like Xero, and a regular process for keeping your books updated — recording invoices and expenses as they happen (or at least weekly), reconciling your bank account once a month, and checking your GST liability before the BAS is due.
Do I really need a separate business bank account?
Yes — it's step one, before anything else. Mixing personal and business money makes it hard for your bookkeeper to reconcile cleanly, harder for your accountant, and leaves you scrambling when you need to claim deductions or prove business income. It takes five minutes to set up and saves you hundreds of hours later.
When does a new business need to register for GST?
If your turnover is over the GST threshold ($75,000 annually for most businesses), you need to register for GST. Once you do, you'll lodge a BAS either quarterly, monthly or annually depending on your turnover — and you can register early, even before you reach the threshold.
