Invoicing Tips & Best Practices for Web Developers
Upfront Deposits & Retainers: Require an upfront deposit of 30% to 50% before commencing project work or repository provisioning. For ongoing projects, transition to bi-weekly milestone invoicing or retainers paid in advance.
Common Invoicing Pitfalls:
- Failing to explicitly state repository transfer and intellectual property licensing conditions upon final payment.
- Not establishing clear boundaries between bug fixes covered under warranty versus out-of-scope feature requests.
- Omitting third-party hosting, API fees, or asset licensing expenses from initial cost breakdowns.
- Working across multi-week milestones without intermediary billing or progress sign-offs.
Cross-Border Considerations: Cross-border B2B software services frequently qualify for zero-rated VAT/GST or reverse-charge rules. Always record the client's country of establishment and valid foreign tax ID on the invoice.
Australia Tax Administration & Retention Rules
Turnover & Registration: Annual gross business turnover reaches or exceeds AUD $75,000 ($150,000 for non-profit organizations).. Operating under this fiscal cap permits exempt billing in eligible circumstances while requiring complete invoice ledgers.
Chronological Numbering: Unique reference number identifying the document. For taxable supplies of $1,000 or more, buyer identity or ABN is legally mandatory.
Payment Terms & Late Penalties: National commercial law safeguards receivables. Typical credit windows span 30 days.
Record Archive Period: Maintain complete accounting records and supporting documents for a statutory minimum of 5 years.
Electronic Invoicing Mandate: The prevailing national status is optional. Electronic PDF instruments remain legally acceptable: yes.
