Before you get in touch

How much will the work cost?

We haven’t verified a current fee schedule for this listing. Ask for a written quote that separates bookkeeping, BAS work, payroll and any catch-up work. Our BAS-agent fees guide explains what to compare.

What should I include in my first enquiry?

Mention your business type, accounting software, number of employees and whether your books are up to date. Explain the help you need and any deadlines. Ask the practice how to share documents securely before sending sensitive records.

Is this a recommendation from Australian Small Business Guide?

No. This is an independent directory listing, not an endorsement, quality ranking or confirmation that the agent is taking new clients. No provider pays for position in this directory.
