OpenAI splits ChatGPT into three business tiers, and the naming alone trips up a lot of Australian SMB owners. Team, Business and Enterprise sound like a straightforward ladder, but the feature gaps between them, and the AUD cost once you convert from USD pricing, matter more for a 15 to 60-person company than the marketing page lets on. Here's what each tier actually includes, what it costs a Sydney or Melbourne business in practice, and where Claude's Team and Enterprise plans fit as a genuine alternative rather than an afterthought.
ChatGPT Team: the entry point most SMBs actually buy
Team sits at roughly $30 USD per seat per month on an annual commitment, which lands around $47 AUD per seat once currency conversion and the local card surcharge most banks apply are factored in. For a 20-person marketing agency that's close to $11,280 a year just in licence fees, before anyone has connected a single business system. Team includes admin controls, higher usage limits than the consumer plan, and access to custom GPTs, but it does not include single sign-on, audit logs, or the data residency guarantees a compliance-conscious business will eventually need.
The gap shows up fastest for firms in regulated industries. A financial advisory practice in Melbourne subject to ASIC's record-keeping obligations will find Team's admin console thin once a compliance officer asks where prompts and outputs are actually stored and for how long.
Business and Enterprise: where the real cost sits
Business tier adds SSO, more granular admin roles and a connector framework for internal tools, typically priced per-seat with a minimum seat count that pushes smaller teams into an awkward spot: you're paying for headcount you don't have just to unlock the compliance features you do need. Enterprise removes the seat minimums in favour of a custom quote, and OpenAI's sales process for that tier is built around businesses with 100+ staff, not the 30-person accounting firm in Parramatta trying to work out whether AI is worth the line item.
Team: lowest per-seat cost, weakest admin and compliance controls, no minimum seat count.
Business: SSO and connectors unlocked, but often gated behind a minimum seat purchase that inflates cost for small teams.
Enterprise: full data controls and custom terms, but a sales-led process that assumes enterprise headcount and budget.
Where Claude fits the comparison
Claude's Team plan is priced comparably per seat but doesn't force a minimum seat count to access SSO-equivalent admin controls, which matters for an Australian business scaling from 8 to 20 people over a year rather than jumping straight to 100. Claude Enterprise offers the same data governance rigour OpenAI reserves for its top tier, but the sales conversation is scoped for mid-market Australian buyers rather than assuming a US-style enterprise procurement team on the other end.
The practical difference shows up in the compliance conversation. When an APRA-regulated client or a Privacy Act-conscious client asks where their data goes, a Claude subscription agreement gives your legal team something concrete to review in a single sitting rather than a multi-week enterprise sales cycle just to see the actual contract terms.
What this costs a real Australian SMB
A 15-person accounting firm on ChatGPT Team: roughly $8,460 AUD a year, with no SSO and limited audit logging.
The same firm on ChatGPT Business with a forced 20-seat minimum: closer to $19,200 AUD a year for five seats they don't need.
The same firm on Claude Team at 15 seats: comparable per-seat pricing without the seat-minimum penalty, landing near $8,900 AUD a year with SSO-equivalent controls included.
None of this is an argument that ChatGPT is a bad product. It's a genuinely capable tool and plenty of Australian businesses run it well. The point is that the tier names hide a real cost difference once you map actual headcount against actual feature needs, and the seat-minimum structure on Business tier in particular can quietly double the effective cost for a team under 25 people.
How to decide without a sales call
Start with the compliance question, not the feature list. If your business handles client financial data, health records, or anything an Australian regulator would ask about in an audit, you need SSO and audit logging from day one, which rules out Team-tier plans from either vendor. From there, compare per-seat cost at your actual headcount, not the vendor's suggested tier, and get the data handling terms in writing before you commit annually. A short paid pilot, a few weeks with a handful of seats on the mid tier, tells you more about fit than any comparison chart, including this one.
