BAS & IAS preparation,
done in 60 seconds.

Built by accountants, for accountants
Designed inside Next Level Accountants — a real Australian accounting practice that needed BAS prep to stop eating our evenings. Now used to prepare quarterly statements for our entire client roster.
Quarterly BAS shouldn't take all weekend.
Most Australian practices spend 30–90 minutes per BAS pulling Xero data, building reconciliations in a spreadsheet, double-checking GST and PAYG, then writing the partner sign-off note. Multiply by 20 client orgs and a quarter is gone.
BAS Pro replaces that workflow with a single click. Connect once, run anytime. The output is a 9-tab Excel workbook your reviewer can sign without re-opening Xero.

Does BAS Pro lodge to the ATO for me?
No — BAS Pro produces the figures and 9-tab working papers. You still lodge through Xero or your usual lodgement portal. We're a preparation tool, not a lodgement agent.
Do you store my client transactions?
BAS Pro caches calculated figures, reconciliations, and the resulting workbook. We don't keep raw transaction-level Xero data after the run completes. Disconnect any org at any time and the OAuth grant is revoked at Xero immediately.
Is my data used to train AI models?
No. We use Anthropic's Claude API for partner sign-off commentary only — and only aggregated figures (W1, W2, G1, etc.) are sent. Anthropic's commercial terms prohibit them from training on API inputs. See our Privacy Policy for the full statement.
How many client orgs can I connect?
Starter: up to 5 client Xero organisations. Practice: up to 25. Firm: unlimited. Every plan has unlimited users on your team — invite the whole practice without paying per seat.
What about IAS / payroll data?
BAS Pro handles IAS using a Xero Custom Connection per org for payroll data (Xero restricts payroll API access on Web App OAuth). The setup is one-time per org and takes about 2 minutes.
Where is my data stored?
Microsoft Azure data centres in Australia East (Sydney). Encrypted in transit (TLS 1.2+) and at rest (Fernet AES-128). We're built for Australian compliance from the ground up.
