Use a project engagement when you have a defined outcome with a clear end, such as a brand identity, a launch film or a new website. Use a retainer when the need is continuing and unpredictable in detail, such as regular content, campaign support or ongoing site changes. Many businesses use both: a project to build something, then a retainer to keep it working.
This article compares the models without quoting rates; fees vary too widely by studio and scope to say anything useful.
The two models in plain terms
Project-based: a fixed scope, deliverables and timeline, agreed before work starts. Change requests are handled as variations. It ends when the deliverables are accepted.
Retainer: an agreed amount of access to a studio over a period, such as a set number of hours, a set list of recurring deliverables, or reserved capacity. It continues until either side ends it under the agreement.
Comparison
| Factor | Project | Retainer |
|---|---|---|
| Best for | One-off, defined outcomes | Continuing, varied needs |
| Scope clarity | High at the start | Lower: defined as a pool or a recurring list |
| Flexibility | Changes need variations | Priorities can shift within the pool |
| Budget predictability | High for the scope | Predictable per period, uncertain in output |
| Studio familiarity with you | Rebuilt for each project | Builds over time |
| Risk of unused capacity | None | Possible if demand is lumpy |
| Risk of scope creep | Managed by variations | Managed by prioritisation |
| Exit | Natural at completion | Needs notice terms |
Match the model to demand
Ask four questions:
- Is the work defined? If you can list the deliverables and how you will judge them, a project fits.
- Is it recurring? If the same type of work arrives monthly, a retainer reduces repeated briefing and quoting.
- How predictable is the volume? If it spikes around launches and seasons, a retainer sized for the average may leave you short at the peak and idle at the trough. Peaks and troughs are the usual cause of retainer waste.
- How fast must changes happen? If you need quick turnarounds on small tasks, reserved capacity helps. If speed is not critical, ad hoc project quotes may suit.
A common pattern: a project to establish a brand, website or campaign system, followed by a smaller retainer for maintenance and iteration. Work that mixes build and maintenance may need separate agreements so each is judged on its own terms.
Governance matters more than the label
Either model can go wrong when the rules are vague. Settle these in writing:
- What is included, and what counts as out of scope.
- How requests are made and prioritised, and who on your side can make them.
- How unused capacity is treated: does it roll over, expire or get credited?
- Approval process and turnaround expectations, set as targets only where the studio agrees to them.
- Reporting: what you will see each month, and what decisions it informs.
- Review points: for retainers, a periodic check on whether the model still fits.
- Notice and exit: how either side ends the agreement, and what handover is owed.

Ownership and licensing under both
IP Australia’s guidance on who owns IP says contractors generally own the IP they create unless the contract says otherwise, and names websites, designs, drawings, databases and logos as examples. It recommends a written contract before work starts that covers who owns the IP, who can use it commercially, when any transfer of ownership happens and whether others can modify it. business.gov.au’s overview of intellectual property adds that copyright does not require registration, while trade marks do.
This is critical for retainers, where work accumulates across many small tasks. Decide up front whether each deliverable transfers to you when paid for, and who owns reusable templates, tools or source files the studio builds along the way. This is general information, not legal advice; have the agreement reviewed.
Hybrid options
- Project plus support period: a project followed by a fixed period of included fixes.
- Capacity retainer: reserved days each month, spent on whatever matters most.
- Deliverable retainer: a fixed list, such as a set of social videos each month.
- Advisory retainer: strategic input and reviews, with production quoted separately.
Each has the same test: can both sides tell, at month-end, whether the arrangement delivered what was agreed?
Warning signs
- A retainer with no description of what it buys.
- A project with a vague scope and no variation process.
- No way to see how capacity was used.
- Pressure to commit for a long term without a review point.
- Ownership terms that are silent.
Where it fits in your budget
Decide the model before you decide the number. Budget by outcome and period, and check how it fits your wider allocation; marketing budget allocation can help.
