Xero Setup for Small Businesses: What Should Be Done Properly From Day One

Xero Setup for Small Businesses: What Should Be Done Properly From Day One

General information only. This article does not constitute financial, tax or legal advice. Please consult a registered BAS Agent or Xero advisor for advice specific to your business.

Xero is one of the most popular cloud accounting platforms for Australian small businesses — and for good reason. It's well-designed, integrates with hundreds of apps, and makes bank reconciliation and BAS preparation much easier when it's set up correctly.

The problem is that many small businesses in Perth start using Xero without setting it up properly. They connect their bank feed, start entering transactions, and assume it will all work itself out. Months later, they have a Xero file full of errors, duplicate transactions, incorrect GST coding and no clear picture of their finances.

A proper Xero setup from day one prevents all of that.

Why Xero Setup Matters

Xero is only as good as the data in it. If the foundation is wrong — the wrong chart of accounts, incorrect GST settings, bank feeds not set up properly, payroll not configured correctly — every report, every BAS figure and every decision based on those numbers will be unreliable.

A proper setup takes a few hours upfront but saves dozens of hours of corrections later.

What a Proper Xero Setup Includes

1. Organisation Settings

The first step is getting your organisation settings right:

• Legal business name and trading name
• ABN
• GST registration status and GST basis (cash or accrual)
• Financial year start date
• BAS lodgement frequency (quarterly or monthly)
• Base currency
• Industry type

Getting the GST basis wrong (cash vs accrual) is a common mistake that affects every BAS you prepare.

2. Chart of Accounts

The chart of accounts is the backbone of your Xero file. It determines how transactions are categorised and how your reports are structured.

Xero provides a default chart of accounts, but it often needs to be customised for your specific business. For example:

• A tradie might need accounts for materials, subcontractors, tools and vehicle expenses
• A retail business might need separate accounts for different product categories
• A service business might need accounts for different types of income

A well-structured chart of accounts makes your profit and loss report meaningful — not just a list of numbers.

3. Bank Feeds

Bank feeds automatically import transactions from your bank accounts into Xero. Setting them up correctly means:

• Connecting all business bank accounts and credit cards
• Setting the correct opening balance date
• Making sure the opening balance matches your actual bank statement

If bank feeds are set up with the wrong opening balance, your reconciliation will never balance.

4. GST and Tax Settings

For GST-registered businesses, Xero needs to know:

• Whether you report GST on a cash or accrual basis
• Your BAS lodgement frequency
• Which tax rates apply to different types of transactions

Xero has a range of tax rates built in (GST, GST-free, BAS Excluded, etc.) but knowing which one to apply to each type of transaction is where many business owners make mistakes.

5. Invoicing and Branding

If you send invoices to customers, Xero's invoicing feature should be set up with:

• Your business logo
• Your payment terms
• Your bank account details (so customers can pay you)
• Invoice numbering

A professional-looking invoice with clear payment details gets paid faster.

6. Payroll (If You Have Employees)

Xero payroll setup is one of the most important — and most complex — parts of the setup process. It includes:

• Employee details and tax file numbers
• Pay schedules and pay rates
• Leave entitlements
• Superannuation settings
• Single Touch Payroll (STP) connection to the ATO

Payroll errors are expensive and time-consuming to fix. Getting it right from the start is essential.

7. Opening Balances

If you're moving to Xero from another system (or from a spreadsheet), you'll need to enter opening balances for:

• Bank accounts
• Accounts receivable (outstanding invoices)
• Accounts payable (outstanding bills)
• Fixed assets
• Loans

Incorrect opening balances mean your balance sheet will never be right.

8. User Access and Permissions

Xero allows you to give different people different levels of access. Your bookkeeper, accountant and any staff who need to enter data should have the appropriate access level — not everyone needs full admin access.

Common Xero Setup Mistakes to Avoid

• Starting with the default chart of accounts without customising it
• Setting the wrong GST basis (cash vs accrual)
• Connecting bank feeds with the wrong opening balance date
• Not setting up payroll correctly before the first pay run
• Giving everyone admin access
• Not connecting Xero to the ATO for STP before running payroll

Do You Need a Xero Advisor?

Xero has a network of certified advisors who have been trained and assessed on the platform. Working with a Xero-certified bookkeeper for your initial setup means:

• Your settings are correct from the start
• Your chart of accounts is structured for your business
• Your bank feeds are set up and reconciling correctly
• Your payroll is configured and STP-connected
• You understand how to use the system day to day

At The Perth Bookkeeper, Agnieszka is a Xero Gold Partner and certified advisor who has set up Xero for many Perth small businesses across a range of industries.

What About Xero Training?

Once your Xero file is set up correctly, a short training session can make a big difference. Many business owners want to be able to:

• Send invoices and reconcile payments
• Check their profit and loss report
• See their cash position
• Run basic reports for their accountant

A Xero training session tailored to your business means you're using the software confidently — not guessing.

FAQ: Xero Setup for Perth Small Businesses

How long does a Xero setup take? A basic setup for a sole trader or simple small business can take a few hours. A more complex setup — with payroll, multiple bank accounts, opening balances and a customised chart of accounts — may take longer.

Can I set up Xero myself? Yes, but many business owners find that getting professional help upfront saves significant time and prevents errors that are difficult to fix later.

What is the difference between cash and accrual GST? On a cash basis, you report GST when money is received or paid. On an accrual basis, you report GST when invoices are issued or received. The right choice depends on your business — ask your BAS Agent or accountant.

Do I need a Xero subscription? Yes — Xero is a subscription-based platform. Plans vary in price depending on features. Your bookkeeper or advisor can recommend the right plan for your business.

What if my Xero file is already set up incorrectly? A Xero cleanup or catch-up bookkeeping service can correct errors, reconcile accounts and get your file back on track.
