  • 5.For corporate clients, follow their PO process to avoid payment delays

Frequently asked questions

Hourly rate or fixed-bid?

Time-and-materials suits research-heavy or ambiguous scope. Fixed-bid suits well-scoped features. Most senior devs use T&M with weekly invoicing.

Should I charge GST as a software contractor?

If your annual contracting income exceeds $75,000 — yes. Most senior contractors are GST-registered.

How do I handle US clients paying in USD?

Invoice in USD; the template supports any currency. Report values in AUD on your BAS using the ATO's daily exchange rate.

What payment terms work?

Net 14 for SMB, Net 30 for corporate. Net 7 for short-term contracts. Always include a PO number if the client requires one.
