Build a project quote by phase and hourly rate. Add expenses with markup, set your contingency, toggle GST, and copy the summary straight into a proposal.
How to price a project properly
Most freelancers underprice their projects for one of two reasons: they underestimate hours, or they forget to account for everything that isn't direct delivery time. A proper project quote has four components:
Break the project into distinct phases with realistic hour estimates. Discovery, design, build, testing, and handover should each be costed separately.
Any costs you pass through to the client — software, stock assets, subcontractors — should carry a 10–20% management markup.
10–20% on top of your subtotal. Covers scope creep, unexpected complexity, and revision rounds. Not optional on fixed-price work.
If you're GST-registered, add 10% and remit it to the ATO. Always state clearly whether your quote is ex-GST or inc-GST.
The hidden hours most freelancers miss
When estimating hours, most freelancers account for the direct work but forget the surrounding activities that are just as real:
| Activity | Typical hours |
|---|---|
| Scoping calls and discovery | 2–8h |
| Writing the proposal / SOW | 1–4h |
| Client communication throughout | 2–10h |
| Feedback rounds and revisions | 4–20h |
| Internal review and QA | 2–8h |
| Handover, documentation, training | 2–8h |
| Admin: invoicing, chasing payment | 1–3h |
Add a separate "Project management" phase to your quote or build this into your contingency.
