Frequently asked questions

Do consultants need to charge GST?

If your turnover is over $75,000 per year, yes. Most established consultants are GST-registered. The template includes a 10% GST line you can remove if not applicable.

Should I bill hourly or by project?

Hourly suits open-ended work; fixed-fee suits well-scoped projects. Day rates work for workshop or executive-coaching engagements. The template handles all three — just adjust the line items.

How do I invoice for travel and expenses?

List travel, accommodation, and other disbursements as separate line items at cost (or with a small markup if your engagement letter allows). Always attach receipts for expenses over $100.

What payment terms should consultants use?

Net 14 for SMB clients, Net 30 for corporate. For long engagements, invoice fortnightly or monthly rather than at the end — protects your cash flow.
