Pricing Models
Agency pricing and commercial models
Understand agency fee models, identify costs outside the service fee and compare the complete commercial commitment.
To assess an agency price, identify what work it buys, what costs sit outside it and what conditions can change it. Choose a fee model that fits the work, then compare the full commitment over the same period. A lower fee can be good value when its narrower scope meets your needs and your team covers the rest.
Match the model to the work
| Model | Usually worth considering when | Clarify before agreeing |
|---|---|---|
| Retainer | Work recurs and priorities may change | Included service or capacity, review period and treatment of extra work |
| Fixed project fee | The output and major dependencies can be described | Deliverables, milestones, revisions and how changes are priced |
| Hourly or daily fee | The task is limited but effort is uncertain | Rates, authorised tasks, estimates, spending limit and updates |
These are commercial arrangements, not grades of agency quality. A fixed fee gives a clearer price for the agreed job, but it does not price every later request. Time-based billing lets an investigation develop, yet needs a way to control spend. A retainer's value depends on what the agency commits to do each period.
If the work cannot yet be scoped, consider a bounded diagnostic stage with a usable output, then decide separately on implementation. An agency may also combine models. Ask where one priced stage ends and the next begins.
Agency Pricing Models: Key Features and Considerations
- RetainerBest for recurring work with changing priorities; includes committed capacity, review periods, and handling of extra work.
- Fixed Project FeeIdeal when deliverables and dependencies are clear; covers milestones, revisions, and change pricing.
- Hourly or Daily FeeSuitable for uncertain effort; requires defined rates, authorised tasks, spending limits, and regular updates.
Pros and Cons of Time-Based vs Fixed-Fee Billing
- Time-Based Billing – Pros
- Allows flexibility for evolving tasks; supports investigative work without rigid scope.
- Time-Based Billing – Cons
- Risk of uncontrolled spend without caps or regular reporting.
- Fixed-Fee Billing – Pros
- Clear price for agreed scope; easier budgeting and planning.
- Fixed-Fee Billing – Cons
- Doesn’t cover unforeseen changes; may require separate quotes for additional requests.
Identify the complete commitment
Request a written account of outputs, quantities or cadence, client inputs, review allowance and completion point. Separate the agency fee from media purchases, software, licences, production and other supplier charges. Mark each amount as included, separately priced, estimated or unresolved. Record work your own team must do, even though it will not appear on the agency invoice.
For paid media, establish who pays the platform or publisher and which planning, setup, management, creative and reporting tasks the agency fee covers. If the agency buys media on your behalf, ask how rebates, commissions, mark-ups or other media-related benefits are handled under the proposed agreement.
Compare quotes on the same GST basis. Check whether each amount includes applicable GST and whether a third-party charge is an estimate. Do not add a charge twice when the agency's quoted total already includes it.
How to Evaluate a Complete Commercial Commitment
- Request written details on outputs, cadence, client inputs, and completion criteria.
- Separate agency fees from third-party costs (media, software, production).
- Identify client responsibilities not covered by the agency fee.
- Confirm who pays platform fees and what agency services are included in media management.
- Verify GST inclusion and avoid double-counting estimated charges.
Key Compliance and Transparency Standards in Australian Agency Contracts
- GST Inclusion
- All quoted fees must include applicable GST unless stated otherwise.
- ABN Requirement
- Agencies must provide their ABN; clients should verify it via the ATO.
- Media Rebates & Mark-ups
- Transparent disclosure required under MFA Transparency Framework.
- Contractual Binding
- Accepted quote becomes legally binding contract under Australian law.
Make the quote a usable commitment
Check that the quote identifies both parties clearly. It should show the business name, ABN and contact details, plus the customer's name and contact details. A written contract can include each party's full legal name and business address, an ABN where needed, and an ACN if it differs from the last nine digits of the company's ABN.
Dates make a quote actionable. Check proposed work start and finish dates, a quote expiry date, and space to record acceptance by signature and date. If the expiry date passes before you accept, ask for a revised quote; do not assume the price and schedule still apply.
An accepted quote can become a legally binding contract. Before you accept, read the quote and any attached schedules together, and ask for unclear terms to be explained in plain English. A short written agreement can set out the work or results, payment details, and the conditions for treating the work as finished.
Check that the price is itemised and totalled, with GST included if applicable. Payment terms can specify the due date, any late-payment penalties and the preferred payment method.
For a smaller engagement, the written terms can stay simple while recording what each party expects. They can state how the parties will handle a dispute and what conditions must be met before the work is considered finished. Use the agency's and your business's names consistently so responsibility for each commitment is clear.
Essential Elements of a Usable Quote
- Clear identification of both parties (business name, ABN, contact details)
- Defined start and finish dates, plus quote expiry date
- Signature and acceptance date field
- Itemised pricing with GST included where applicable
- Clear payment terms (due date, late penalties, preferred method)
- Dispute resolution process and completion conditions
Agree when payment and price can change
For a project, connect payment milestones to work you can inspect. For a retainer, check when billing starts and how requests beyond the agreed commitment are approved. For time-based work, agree who authorises tasks, when you receive time updates and what happens as an estimate or cap approaches.
Ask for the cost and timetable effect of a material change before approving it. The written arrangement should make clear which work is added or replaced and who can authorise the resulting fee.
Confirm material unknowns in a revised written quote before committing.
The agreed billing schedule affects when cash must be available, even if the total fee is unchanged. Keep the accepted quote and any later written changes together so the current commercial commitment is easy to verify.
