If a client or supplier has ever asked for your registered business address before finalising a contract, it is not an unusual or excessive request. There are specific, practical reasons larger businesses build this into their process.
What they are actually checking
Many contracts include formal "notice" clauses that set out exactly how legal notices must be delivered and to which address [Sprintlaw, sprintlaw.com.au]. Before a business commits to a contract, it wants confidence that the other party is a genuine, traceable entity with a real address where formal correspondence can reach them if something goes wrong later.
Why this is harder to satisfy with a home address
If your registered office or principal place of business is your home, you can still answer the question. The friction tends to come from a different place: many business owners are reluctant to disclose a home address to a new client, even though it is technically valid and already on the public ASIC register if you have a company.
Why it matters more for B2B and larger contracts
Larger commercial clients and government bodies in particular tend to ask for this as a standard part of their onboarding or procurement checklist, since they are managing their own risk around who they are contracting with [Sprintlaw, sprintlaw.com.au]. A clean, professional answer to this question removes friction at exactly the stage where deals can stall over small administrative details.
What a good answer actually looks like
You do not need a leased office to answer this confidently. A real, professional street address, consistent with what is listed on your ABN and ASIC registration, answers the question cleanly without disclosing your home and without raising any follow-up questions about why your details look inconsistent.
Setting this up before it comes up
The best time to sort this out is before a client asks, not in the middle of a contract negotiation when you are scrambling to decide what to disclose.
