Charge monthly SaaS bookkeeping retainers based on monthly recurring revenue (MRR) transaction volume tiers, billed in advance. Standard commercial settlement in New Zealand operates under Net 20 terms.
Protective Legal Clauses & IP Rights
Disclaim liability for payment gateway API sync outages, mandate client confirmation of exchange rate policies, and enforce 14-day settlement windows. Under New Zealand commercial law, contracts should clearly define tax point dates and liability caps.
Allowable Business Expenses & Tax Write-Offs

Invoicing Tips & Best Practices for Bookkeepers
Upfront Deposits & Retainers: Charge monthly recurring retainers payable in advance on the 1st of each month. For historical clean-up projects or backlogged accounts, bill an upfront retainer of 50% before undertaking bank data extraction.
Common Invoicing Pitfalls:
- Failing to define explicit transaction volume thresholds, leading to scope creep when client sales surge.
- Not establishing clear deadlines for clients to furnish bank statements and expense receipts before tax filing cutoffs.
- Omitting third-party cloud accounting subscription fees or receipt-scanning software costs from billing terms.
- Performing certified CPA-level statutory audits without appropriate professional licensing or separate engagement letters.
Cross-Border Considerations: Cross-border bookkeeping and virtual accounting services supplied to foreign business entities typically qualify for zero-rated export status or reverse-charge rules under destination-principle VAT legislation.
New Zealand Tax Administration & Retention Rules
Tax Thresholds: Annual gross turnover exceeds or is expected to exceed NZD $60,000 in a 12-month period.. If annual revenues fall below this threshold, mandatory tax charging may not apply, though meticulous sales ledgers remain obligatory.
Sequential Numbering: Sequential reference number. Under modernized Taxable Supply Information rules (April 2023), buyer name and address required for supplies exceeding NZD $1,000.
Statutory Late Interest: Commercial agreements provide payment protection. Standard terms default to Net 20.
Audit Retention: You are legally required to retain all commercial invoice archives for at least 7 years.
E-Invoicing Requirements: Current B2B e-invoicing status is optional. Digital PDF invoices are officially recognized: yes.
