The reality

Staying organised is a lot easier than keeping it all in your head.

Compliance deadlines are easy to lose track of when you are running a business. Complia keeps every BAS, super and ASIC date in one place, so staying organised takes care of itself.

The usual way

  • Due dates live in your head and a messy calendar
  • A BAS date can slip past before you notice
  • ASIC reviews sneak up once a year
  • Every deadline is a fresh scramble

With Complia

  • Obligations mapped to the real ATO calendar
  • Reminders with time to actually prepare
  • A checklist for exactly what to lodge
  • Custom deadlines tracked alongside the rest

Complia maps your obligations to the Australian calendar, reminds you before each one, and walks you through exactly what to prepare.

How it works

Three steps to never missing a deadline.

Tell Complia your obligations, get reminded in time, and work the checklist for each one.

Complia is an organisational tool that tracks dates and preparation steps. It is not tax, legal or financial advice and does not replace your accountant.

What you get

Everything that keeps you compliant — nothing that pretends to be your accountant.

Built around the real Australian calendar, so the dates and steps are the ones that actually apply.

BAS, super, and ASIC tracking

Your obligations mapped to the real Australian calendar, so every lodgement date is accounted for.

Preparation checklists per obligation

Each obligation comes with a step-by-step checklist, so you know exactly what to gather and lodge.

Email reminders before due dates

Reminders land with enough lead time to actually prepare — never the morning it’s due.

Built for the Australian calendar

Made around ATO and ASIC obligations and dates — not a generic to-do list bent to fit.

Why it matters

Compliance shouldn’t depend on remembering.

Complia turns every obligation into a date, a reminder and a checklist — so staying compliant is a system, not a scramble.
