For individuals

The accountant you
can't afford, on tap.

One person. One login. One ledger that prepares your BAS, drafts your reminders and gives every posted entry a signed receipt. Ask Bella for the boring parts — you take care of the business.

She works when you ask. You approve.

Who Airtight is for
Sole traders

One-person businesses in Australia. GST-registered or under the threshold.

Freelancers

Designers, devs, writers, consultants. Project tracking + invoicing + tax in one.

Landlords

Properties, depreciation and CGT records. Tenants and rent roll are not built yet.

Side-hustlers

Keep your day-job books separate from your hustle. Each entity has its own books.

What Bella does for you

The bookkeeping you'd otherwise pay a few thousand a year for.

01

Invoicing, faster

Add your logo and what you sell, and ask Bella to draft the invoice. Review it, send it, and include a card payment link. Overdue reminders can go out by hand at any time, or automatically if you turn that on.

02

BAS / GST, prepared

Airtight calculates your BAS from the ledger, and Bella can draft it for review. You — or your registered tax/BAS agent — review it and lodge through the ATO, then record it as lodged in Airtight. NZ GST returns are not built yet.

03

Deductions worth checking

Ask Bella to look for deductions you may have missed, such as home office, depreciation and subscriptions. She suggests; your agent confirms.

04

Plain-English summaries

Ask Bella what changed and what needs attention. She answers in plain English from your ledger, and you approve any change.

05

English and Arabic

The interface works in English and Arabic, with right-to-left layout. Ask in either language.

06

Several entities, kept separate

Run a business and a side project from one login. Each entity has its own books.
