Frequently Asked Questions
Add GST (currently 10%) to your subtotal of billable hours, then display the GST amount separately on your invoice. For example, if you bill 10 hours at $120/hour ($1,200 subtotal), add $120 GST to reach a total of $1,320. You must be registered for GST if your turnover exceeds the threshold. Always show the GST calculation clearly so clients understand the final amount due, and ensure your ABN is visible on the invoice for tax compliance.
Yes, absolutely. List each service type as a separate line item with its own hourly rate and hours worked. For instance, you might charge $150/hour for database design but $95/hour for project management. This approach is professional, transparent, and helps clients understand what they're paying for. It also allows you to justify rate variations based on the complexity or specialization required for each task, making your invoice more credible.
Quarter-hour increments (15-minute units) are industry standard for professional services in Australia and strike a balance between accuracy and simplicity. Many consultants and lawyers round up to the nearest 15 minutes, which clients generally accept. Some charge in half-hour blocks for higher-level work. Establish a clear policy upfront and stick with it consistently across all invoices to avoid disputes and appear professional.
Be specific enough that clients understand what work was performed without overwhelming them with minutiae. For example, write "Website redesign—homepage layout and CSS implementation" rather than just "web work" or a vague "consulting." Include task names, deliverables, or project phases. Detailed descriptions build trust, reduce payment queries, justify your rates, and provide clear documentation for both parties if questions arise later.
Australian tax law requires invoices to include your business name, ABN (or ACN for companies), invoice date, invoice number, a description of the service provided, and the amount due. For billable hours specifically, you must clearly itemize the hours and rates. There's no legal requirement to provide detailed time records on the invoice itself, but you must maintain time records separately for tax purposes and ATO compliance.
Group rates by service type or expertise level, and ensure they reflect your qualifications and market positioning. For example, senior consultation rates are naturally higher than junior support rates. Include brief context in your client agreements about what determines each rate—expertise, complexity, urgency. On the invoice, consistency matters more than justification; if your rates are well-established in your client agreement, your invoice simply reflects that.
Have detailed time records ready—timestamps, task descriptions, and duration for each entry—to support your invoice. If the dispute is valid, discuss it professionally and adjust accordingly. If your time tracking is accurate, calmly walk the client through your records. Preventing disputes starts before invoicing: communicate progress updates, set hourly rate expectations upfront, and use time tracking software to maintain an audit trail that demonstrates professionalism and accuracy.
Time tracking software is strongly recommended for billable work. It automatically logs hours as you work, eliminating memory gaps and reconstruction errors that erode client trust. Software integrates directly with invoicing, reduces data entry mistakes, and provides audit trails for compliance. A manual template works if you have just a few invoices monthly, but as your volume grows, software saves time, improves accuracy, and makes it easier to generate professional invoices consistently.
