New Zealand businesses should keep records that support income, expenses, payroll, tax filings, assets and business decisions, and those records should be easy to retrieve.

Core records to keep

Good record keeping supports compliance, helps explain business performance and reduces friction when preparing reports or returns.

Records should cover sales, costs, payroll, assets, liabilities and the source documents behind those entries.

  • Sales invoices and income records
  • Supplier invoices and expense support
  • Bank, payroll and tax records

Why organised records help beyond compliance

Well-kept records make it easier to understand margins, cash flow and working capital. They also reduce time spent chasing documents later.

For growing businesses, record discipline is often the base layer for better reporting and stronger systems.

Frequently asked questions

What if our records are inconsistent?

That usually means the bookkeeping workflow should be reviewed and tightened.
