Who uses PayWren
If you invoice clients and work for yourself in New Zealand, PayWren is built for you.
Where your money sits
You hold the tax money. Not a tax agent.
Percentage-of-income services take a cut of every payment and hold your tax for you. PayWren just works out the number and leaves the money where it is: in your own account, earning your interest, until IRD is actually due.
On your dashboard
What's yours to spend, what's IRD's
Every paid invoice splits into two numbers: what's clear to spend, and what to set aside for GST and income tax. PayWren keeps a running monthly set-aside figure, so the money is there when the bill lands, and not a day before.
Illustrative split on a $6,900 paid invoice.
Worked example
Priya, a consultant in Wellington
After a strong first year, her residual income tax lands over $5,000. That tips a sole trader into provisional tax the next year, paid in three instalments. Because the money was set aside as each invoice was paid, and the standard-uplift amounts went in on time, the year-end square-up carried no use-of-money interest, which otherwise runs around 10.9% a year.
Cited: Tax Administration Act 1994, provisional tax (s RC 3), use-of-money interest (s 120D)

PayWren started as a personal tool. A New Zealand consultant needed it for his own contracting work and couldn't find something quiet, honest, and priced fairly. It's still run the same way.
