For bookkeepers and BAS agents

You’re closest to the numbers. You should be first to know.

A client’s GST registration stopped six weeks ago. You’re still coding GST on every invoice. Nobody told you, because nobody told them.

It was on the Australian Business Register the day it happened.

Catchwind tells you that day.

What lands in your inbox

10 sources for bookkeepers and bas agents · current as at 3 October 2026

Business status

ABN and GST registrationNational

You hear when a client’s ABN is cancelled, their GST registration starts or stops, or they add or drop a trading name, so you are not caught out at BAS or tax time.

Charity registerNational

For clients that are charities, or run one, you hear about changes to their charity status or size, which change their reporting rules.

Company registerNational

You find out when a client company changes name or status, or is heading for deregistration, often before the client thinks to tell you.

Names and structure

Business namesNational

A new business name often means a new product, shop or side business. A cancelled one can mean something has closed. Either is a reason to check in.

Licences and registrations

Queensland building licences (QBCC)QLD

For builder and trade clients you hear when their licence classes or financial category change. The financial category is a turnover story in itself.

Tax and BAS agent registrationsNational

You hear if a practice you work with, or a client that is a tax or BAS agent, has its registration changed or ended.

Regulator action

ASIC action announcementsNational

If a client is named in an ASIC release, you hear it from us, not from the newspaper.

Contracts and grants

ACT Government invoices paidACT

You hear when a client is paid for government work in the ACT, a sign of new or growing government business.

Federal government grantsNational

You hear when a client wins a federal grant, so you can plan the tax treatment, the reporting and the cash flow with them.

Queensland small-business grantsQLD

You hear when a Queensland client receives a state grant, so you can treat it correctly for tax and reporting.

Illustrative scenarios

How it plays out

Alert

The quarter you didn’t have to redo.

An alert on a Wednesday: Sample Cafe’s GST registration has been cancelled. You stop, ring the owner, and get it sorted before another week of invoices goes through the wrong way.

Monday digest

The grant that needed coding.

Monday’s digest: Sample Landscaping has received a Queensland small-business grant. You know how to treat it before it shows up as a mystery deposit in the bank feed.

Monday digest

The second business in the same bank account.

A new business name, Sample Mowing, registered to a client’s ABN. You ask whether it needs its own set of books now, not after twelve months of tangled transactions.

Monday digest

The licence that says more than the client did.

A builder client’s QBCC financial category changes. That’s a turnover story, and it’s in your inbox before the client mentions the year they’ve had.

Why bookkeepers sign up

  • Stop cleaning up after changes you weren’t told about.

    ABN and GST status reaches you when it changes.

  • Be the one who spots it.

    You become the person who notices things, to your client and to their accountant.

  • Protect your own registration.

    Lodging on a wrong GST status is your problem too.

  • Clients who stay.

    A bookkeeper who rings with “I saw this, here’s what we do” doesn’t get replaced by software.

  • 78 cents a client, or less.

    Starter covers 50 clients for $39 a month.
