The few things that matter most

Kōuka is built around the questions independent workers actually have, without turning simple admin into a bookkeeping course.

01

Know what needs to be kept aside

See an estimate for GST, income tax and ACC based on the records you have entered, with the calculation detail available when you need it.

02

Turn work into invoices

Log time by client, project and phase, then bring unbilled work into a professional invoice.

03

See how your business is tracking

Review income, expenses and estimated profit in clear summaries, so you can understand the bigger picture without digging through spreadsheets.

A simple rhythm that keeps things moving

Record small things as they happen. Kōuka keeps watch in the background and helps turn the result into something useful.

1

Log it

Add time, income or an expense without unnecessary fields.

2

See where you stand

Your dashboard updates estimated GST, income tax, ACC, upcoming dates and unbilled work from the records you enter.

You are not left alone with the admin

Ask Kōuka is a friendly helper built into the app. Get plain-English guidance about everyday admin, GST basics, categories, or how a feature works.

Ask Kōuka provides general guidance and app help only. It does not replace professional accounting, tax, legal or financial advice.

Ask Kōuka
Your friendly admin helper
Where should I record my Adobe subscription?
Usually under software and subscriptions. If you use it partly for personal work, you can also set the business-use percentage.
Do I need to charge GST if I'm under $60k?
Not yet — GST registration is only required once your taxable supplies hit $60,000 in a 12-month period. You can register voluntarily before that if it helps your clients.
When do I need to pay provisional tax?
Usually in three instalments during the year if your residual income tax was over $5,000 last year. Kōuka keeps a running tax estimate so there are no nasty surprises.

Made for people working on their own
