What you get on day one

Pick New Zealand when you create the business. Everything below is seeded for you and editable in Settings.

  • GST rates seeded. GST 15%, Zero-rated and Exempt, with GST 15% as the default.
  • Tax Invoice with your GST number. The GST number is checked for format when you enter it and printed on every invoice.
  • NZD amounts, DD/MM/YYYY dates. A total prints as NZ$1,250,000.00, in words as dollars and cents.
  • An April to March financial year. Numbering runs per year: the first invoice is INV-2026-27-0001.
  • Payroll components ready. Salary, Bonus, PAYE (incl. ACC earners' levy), KiwiSaver (employee, members), Student loan and KiwiSaver (employer, members).
  • Phones with +64. Customer, supplier and employee numbers take the +64 format; you and your team sign in with your email.

GST

GST on every line, worked out as you type

Each product carries its GST rate. Pick the customer, type the item, press Enter: GST, totals and the amount in words fill in as you go.

  • Output and input GST posted to their own accounts
  • A tax summary by rate for whoever files your returns
  • Credit notes reverse the tax with the sale

GST in New Zealand

GST in New Zealand: what you need to know

The rules the product is set up around, in plain words. Your accountant confirms what applies to you. Sources: Inland Revenue: taxable supply information, business.govt.nz: GST, Inland Revenue: KiwiSaver changes, Inland Revenue: ACC earners' levy rates.

  • Registration. You must register for GST once your turnover reaches $60,000 in 12 months, or is likely to. Below that, registering is voluntary.
  • Rate. 15% on most goods and services. Exports are zero-rated; residential rent and financial services are exempt.
  • Taxable supply information. Since 1 April 2023 there is no required "tax invoice" document. Over $200, show your name, GST number, the date, a description and the GST; over $1,000 also the buyer's name and an address, phone, email or NZBN.
  • Returns. Monthly, two-monthly or six-monthly. Six-monthly is only open while your turnover stays under $500,000 a year.
  • Requests. A GST-registered customer can ask for the information on any sale over $200, and you have 28 days to give it.

Price

Priced in NZD

Every module is free for 7 days with no card. Premium is then NZ$85 per user per month, the fixed equivalent of USD 50, counted on the people who sign in.

Books

Books that keep themselves

Every invoice, bill and payment posts its own journal in NZD. Profit and loss, the balance sheet and the GST summary are ready any day of the April to March year.

Payroll

Payroll set up for New Zealand

Salary components for New Zealand are seeded when you create the business. Runs build each payslip from the structure and post salary expense and payables when you approve.

  • Salary, Bonus, PAYE (incl. ACC earners' levy) and KiwiSaver (employee, members) ready to use
  • KiwiSaver seeded at 3.5% each, the default since 1 April 2026; the employer's share also carries ESCT
  • The ACC earners' levy (1.75% for 2026–27) is part of PAYE, so it is not a separate line
  • Four weeks' annual leave after 12 months and 10 days' sick leave a year
  • Attendance and leave feed paid days
  • Payslips in employee self-service

FAQ

Questions, answered

Do I need to be registered for GST to use SimpleERP?

No. Setup asks whether you are registered. You must register for GST once your turnover reaches $60,000 in 12 months. Below that, registering is voluntary. If that changes, switch it in Settings; your GST number prints on every invoice once you add it.

What does a SimpleERP tax invoice show?

Your business name and address, your GST number, the customer, a number from a sequence that never repeats, the date, each line with its GST rate, the tax by rate and the amount in words. Your accountant can confirm what your business must show.

How much does SimpleERP cost in New Zealand?

Every module is free for 7 days with no card. After that Premium is NZ$85 per user per month (NZ$1,020 per user per year), the fixed equivalent of USD 50, counted on the people who sign in. See pricing.

Does SimpleERP file my GST returns?

No. It keeps the records and gives you a tax summary by rate and the sales and purchase registers, all exportable to CSV, for whoever files your returns.

Does SimpleERP do payday filing with Inland Revenue?

No. SimpleERP builds payslips and posts PAYE, KiwiSaver and student loan amounts to the payables you remit, but you file the employment information with Inland Revenue yourself or through your payroll provider.

My invoices still say Tax Invoice. Is that wrong?

No. The title is no longer required since April 2023, but it does no harm. What matters is the information: your GST number and the GST on sales over $200, and the buyer's details over $1,000. SimpleERP prints all of it.

Where is my data stored?

In a PostgreSQL database on the hosted service, where row-level security keeps each business to its own rows. Ask us where the service is hosted and how it is backed up, and export your reports to CSV whenever you like.
