How this usually works
Work backwards from the practical goal. Are you creating a brand-new Xero file, cleaning up an existing one, or migrating from MYOB/QuickBooks? Do you need BAS this quarter, payroll with STP 2 before the next pay run, or historic data for a loan application?
Clarify your conversion date, GST method (cash or accrual), banking setup, and whether you need payroll from day one. Then decide if you’ll DIY with a review, or engage a bookkeeper, BAS agent or tax accountant to do the setup and handover.
What is included in a proper Xero setup
- Organisation and financial settings: legal name, ABN, address, financial year, lock dates, currency.
- GST/BAS configuration: register status, cash vs accrual method, tax rates and reporting codes aligned to the ATO.
- Chart of accounts: tailored to your industry, mapped to GST codes, with bank/clearing accounts structured for easy reconciliation.
- Bank feeds: connect bank/credit card/PayPal accounts, set statement import rules and confirm opening balances.
- Opening balances and historicals: enter conversion balances, outstanding invoices/bills and reconcile starting positions.
- Contacts, items and branding: import customers/suppliers, set items, invoice/quote templates and online payment services.
- eInvoicing (Peppol): enable for compliant B2B invoicing where relevant.
- Payroll and STP 2: employees, pay calendars, pay items, super funds (USIs), leave accruals, allowances/deductions and STP 2 enablement.
- Tracking categories and projects: define departments, locations or jobs for meaningful management reporting.
- Fixed assets and inventory: set up asset groups and depreciation rules; simple inventory where applicable.
- User roles and advisor access: correct permissions for owners, staff, bookkeepers, BAS agents and tax accountants.
- Apps and integrations: receipts/capture (e.g., Hubdoc or Dext), payment gateways, POS, time tracking and reporting tools.
- Documentation and training: how-to notes, key reports, month-end checklist and who to contact for BAS/payroll queries.
Australian context to keep in view
- GST and BAS setup flows into every sale and purchase. Incorrect tax codes lead to wrong BAS and potential ATO issues.
- Payroll must meet STP 2, super payment, Award/allowance and leave rules. Errors here affect employees and ATO reporting.
- Your provider fit matters. Bookkeepers handle daily workflows and setup; BAS agents handle GST/BAS compliance; tax accountants handle year-end and structure.
Compare your options via Bookkeeping, BAS agent services, Payroll services and Tax accountants.
Quick checklist before you start
- Confirm ABN and registrations (GST, PAYG withholding) and choose GST basis (cash or accrual).
- Pick a conversion date and export a trial balance, open invoices and bills from your old system.
- List all bank/credit/loan accounts for feeds, plus PayPal/Stripe if used.
- Gather payroll data for STP 2 (TFNs, DOBs, addresses, super details, leave balances, pay items).
- Decide tracking categories (e.g., location, project) and any apps you need from day one.
- Plan who will do BAS, payroll and year-end, and set correct user permissions.
DIY vs professional setup
DIY suits
Simple sole traders, no payroll, few bank accounts, and low transaction volume. Still consider a review before your first BAS.
Use a bookkeeper/BAS agent when
You have payroll/STP 2, inventory, multiple feeds, app integrations, or need a clean migration from MYOB/QuickBooks.
Time and cost
Simple setup: 2–6 hours. Migration with payroll/tracking: 6–20+ hours. Pricing varies by scope, data quality and training needs.
Handover
Ask for documentation, lock dates, and a 30–60 day check-in to confirm BAS and payroll are running smoothly.
Common mistakes to avoid
- Wrong GST basis or default tax rates, causing incorrect BAS lodgements.
- No lock dates, leading to backdated changes and shifting figures.
- Missing opening balances or unallocated historical invoices/bills.
- Bank feeds not reconciled from the conversion date, causing duplicates.
- Payroll set up without proper STP 2 mapping, super details or leave accruals.
- User permissions too broad, risking accidental changes to settings.
What to compare before you commit
Scope
Confirm setup, migration, cleanup, BAS alignment, payroll/STP 2 and training are included.
Software fit
Pick providers fluent in Xero and your chosen apps (e.g., Hubdoc/Dext, payments, POS).
Turnaround and communication
Agree timelines, testing windows for bank feeds and payroll, and escalation paths.
Commercial fit
Check pricing method, support rhythm, month-end assistance and BAS lodgement scope.
Best next steps
Write down the exact outcome you want: a clean migration by a specific date, first BAS lodged correctly, payroll running on STP 2, or streamlined invoicing and payments.
Then shortlist providers against that outcome. If you need ongoing support, review Bookkeeping and BAS agent services. For structure and tax planning, look at Tax accountants. For startups, see New business accountant.
Frequently asked questions
What is Xero setup?
Xero setup is the process of creating or migrating a Xero organisation and configuring it for Australian GST/BAS, bank feeds, chart of accounts, invoice/payment settings, eInvoicing and payroll with STP 2. Good setup prevents rework and supports accurate reporting.
How long does Xero setup take?
Simple files can be ready in 2–6 hours. Migrations with payroll, multiple feeds and tracking categories typically take 6–20+ hours. Allow time for bank feeds, data cleanup and STP 2 testing.
Do I need a bookkeeper, BAS agent or tax accountant?
Use a bookkeeper for day-to-day setup and workflows, a BAS agent for GST/BAS accuracy and lodgement, and a tax accountant for year-end and structure. Many businesses combine these for the best result.
What should I check before switching to Xero?
Confirm registrations and GST basis, pick a conversion date, export a trial balance and open invoices/bills, gather payroll/STP 2 details, plan tracking categories and choose any connected apps you need.
