For individuals

The accountant you
can't afford, on tap.

One person. One login. One ledger that quietly files your BAS, chases your clients and seals every transaction three ways before you wake up. Bella takes care of the boring — you take care of the business.

She works the graveyard shift. You get the morning free.

Who Airtight is for
Sole traders

One-person businesses in AU, GCC, UK. ABN, VAT, free-trade-zone, or plain contractor.

Freelancers

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

Landlords

Residential or commercial, 1–50 properties. Rent-roll, depreciation, CGT tracking.

Side-hustlers

Keep your day-job books separate from your hustle. Bella walls off each entity.

What Bella does for you

Everything you'd pay anaccountant $4,000 a year for.

01

Invoicing that writes itself

Upload a logo, list what you do, and Bella drafts the invoice. One click to send. Payment link baked in. Overdue nudges run on their own.

02

BAS / GST / VAT, no drama

She watches every transaction, categorises it in real time, and drafts your BAS or VAT return when the period closes. You — or your registered tax/BAS agent — review and lodge through the ATO portal.

03

Deductions you'd have missed

Bella spots home-office, depreciation, vehicle log, subscription receipts you forgot. Tax time drops from a long weekend to an afternoon.

04

Books tight by 8am

Overnight she reconciles, flags anomalies in plain English, and leaves the day's summary on top. You skim, sign, go.

05

Bilingual, by default

Ask her anything in English or Arabic. She answers in the language you asked. Every receipt prints in both, no plug-in.

06

Sharia-compliant if you need it

AAOIFI-aligned reporting, zakat calc, halal receipt templates. Turn it on per entity — it doesn't touch anyone else's books.
