Payment clauses in a creative agency agreement and what to get right

Someone has just handed you the payment section of a creative agency agreement. If you are the client, this is the part that tells you what the campaign will actually cost and when your money leaves the account. If you are the agency, it is the part that decides whether you get paid for work you have already done, and how long you have to wait. Both sides tend to skim it, because the creative brief and the scope of work are more interesting. Both sides regret that.

The payment clauses do three jobs. They fix the price, they set out when and how money changes hands, and they decide who carries the out-of-pocket costs of the project, such as printing, stock photography and media buying. They also do something less obvious: they replace informal email understandings about money with terms that can be enforced. Once the agreement is signed, "we will sort that out later" stops being an option.

The payment clauses that decide whether the deal works

How the price is calculated

The first decision is the fee structure. A creative agency agreement usually prices the work one of three ways: an hourly rate for each person involved, a fixed fee for the whole project, or a retainer paid monthly for ongoing services. Hourly pricing needs a fee schedule annexed to the agreement that sets the rate for each role, from creative director down to junior designer. Fixed fees need the scope of work attached, so there is no argument about what the fixed fee buys. Retainers need to say what volume of work the monthly fee covers, for example a set number of hours or deliverables.

The drafting choice that matters: the unit of chargeable time. If hours are rounded up to the next half hour, or time spent in internal meetings is billed, say so. A client who watches a quote blow out because of rounding will not be happy, but a client who was never told is worse.
The trap: a clause that prices work at the agency's standard rates from time to time, with no schedule attached. There is no way to check the price, and the first dispute starts immediately.
The variant the other side pushes for: time and materials with no cap, so the agency bills every hour and the client carries all the risk of the project running long.

What the fees cover, and what they do not

The second decision is the boundary of the fee. The price should cover the services described in the scope of work, and everything outside that scope should be a separately quoted extra. Most fee disputes in creative work are not about the rate. They are about whether a task was included in the fee or was an extra.

Common exclusions: extra rounds of revisions beyond the agreed number, rush or overtime work, stock photography and licensed assets, ad placement and media buying, and printing or production costs.
The trap: drafting the fee as covering all work reasonably required to complete the project. That reads generous, but it means the client pays for whatever the agency decides is reasonably required.
The drafting minimum: tie the fee to defined deliverables and a stated number of revision rounds, so the boundary between included and extra is something either side can check.

GST and how the price is stated

Australian fees are usually quoted exclusive of GST, with the agency adding it on top. GST is charged at 10% of the value of a taxable supply under s 9-70 of the A New Tax System (Goods and Services Tax) Act 1999 (Cth). If the agency is registered for GST, the client can claim an input tax credit for the GST it pays, which is why the agreement should also require invoices that meet the tax invoice requirements.

The drafting choice is to state explicitly whether prices are plus GST or inclusive of it, and to repeat that in the fee schedule. If the agreement is silent, the parties can end up arguing over whether a quoted $50,000 campaign costs $50,000 or $55,000.

Invoicing and when the agency bills

The agreement should say when invoices are issued. For a single campaign, the agency might invoice on completion, on approval of the work, or in instalments tied to milestones. For an ongoing relationship, monthly invoicing is common. The trigger matters as much as the frequency: if an invoice issues only once the client approves the work, the agency's cash flow is in the client's hands.

The trap: invoicing only at the end of a project that runs for months. The agency finances the whole job and carries the risk of a dispute at the end.
The drafting choice: milestone invoices for large projects, with each invoice linked to a stage of work that has been delivered, not approved.
The client's check: confirm the invoicing clause does not let the agency bill twice for the same work, for example a retainer plus hourly charges for work the retainer already covers.

Payment terms and due dates

The payment terms clause fixes how many days the client has to pay. Australian agreements commonly allow 30 days from the date of the invoice, sometimes 14 or 60 in particular industries. The clause should also say how payment is made and what happens if the due date falls on a weekend or public holiday.

For agencies dealing with large corporate clients, the Payment Times Reporting Act 2020 (Cth) requires entities with consolidated revenue over $100 million to report on how quickly they pay small business suppliers. Many of those businesses have also signed the Australian Supplier Payment Code, a voluntary Business Council of Australia initiative that commits signatories to pay eligible small business suppliers within 30 days of a correct invoice. An agency facing a 60 days, take it or leave it position from a large client can point to both.

The trap: a due date tied to the client's internal processes, such as payable within 30 days of approval of the invoice. The client controls approval, so it controls the payment date.
The drafting minimum: the due date should run from the date of the invoice or from delivery, and the client's obligation to pay should not depend on the agency chasing internal sign-off.
The variant the client side pushes for: payment only on final delivery and approval of the whole project, which leaves the agency unpaid during the work and gives the client maximum leverage at the end.

Interest on late payment

Australia does not have a general statutory scheme that entitles a supplier to interest on overdue invoices between businesses, the way some overseas jurisdictions do. The right to charge interest exists only if the agreement creates it, which makes the late payment clause the agency's most important protection after the payment terms themselves.

The usual drafting is a rate, commonly a percentage per month or a rate linked to the Reserve Bank cash rate plus a margin, applied to the overdue amount from the due date. Two limits apply. The first is the common law rule against penalties: a clause that is a genuine pre-estimate of the cost of late payment is enforceable, but a rate set so high that it punishes rather than compensates is not. The second is the unfair contract terms regime. Under s 23 of the Australian Consumer Law (Schedule 2 of the Competition and Consumer Act 2010 (Cth)), a term of a standard form small business contract is void if it is unfair. A contract is a small business contract where at least one party employs fewer than 100 people or has turnover under $10 million, and under s 24 a term is unfair when it creates a significant imbalance, is not reasonably necessary to protect the party's legitimate interests, and would cause detriment. A punitive interest rate in an agency's standard form agreement is exactly the kind of term a court could strike out, and since 2023 regulators can seek penalties against businesses that propose or rely on unfair terms.

The trap: an interest clause with no stated rate, which is unworkable in practice.
The drafting minimum: a stated rate that approximates the real cost of late payment, and a clause that says interest starts on a fixed date after the invoice is due.

Third-party expenses and reimbursements

Creative projects routinely involve spending money that is not the agency's own: printing, stock photography and footage licences, photographers and models, ad placement, media buying, travel, and sometimes software licences. The agreement needs to decide how those costs are incurred and who pays.

The common model is that the agency incurs the cost and the client reimburses it. If that model is used, the clause should set conditions on reimbursement so the client is not writing a blank cheque. The standard drafting requires the agency to obtain the client's prior written approval before incurring a third-party expense above a set amount, to provide an estimate before the work, and to pass the cost through without mark-up unless a mark-up is agreed.

The trap: a clause that reimburses all reasonable expenses with no approval step. The client pays for whatever the agency decided was reasonable.
The drafting choice: a threshold, such as prior written approval for any single expense over $500, plus a requirement that the agency itemise expenses on the invoice.
The agency's point: agencies often add a handling or project management fee to third-party spend. If that is the commercial deal, state the percentage in the agreement rather than burying it in the invoice.

What happens when an invoice is not paid

The agreement should say what the agency can do if an invoice goes unpaid. The usual protections are a right to suspend work and a right to terminate if payment is not made within a set period after written notice. For an agency, these clauses turn a payment dispute from an indefinite standoff into a process with a deadline.

The trap: suspension with no notice period. If the agency simply stops work the day after the invoice is due, the client may treat that as a breach, and the agency can find itself on the wrong end of a claim for delay.
The drafting minimum: a notice period, for example 14 days written notice of intention to suspend, before the right is exercised.
The client's check: the clause should also confirm that the client can withhold or set off amounts genuinely in dispute, so the agency's suspension right is not a weapon to force payment of a disputed invoice in full.

Disputing an invoice

Disagreements over invoices happen even in good relationships: a client thinks a line item was included in the fee, an agency thinks a revision round was an extra. The payment section should provide a way to resolve that without either side withholding the whole amount.

The common drafting is a dispute window: the client must raise an objection in writing within a set number of days of the invoice, and must pay the undisputed part on time while the disputed part is resolved. The window matters because a client who can dispute an invoice months later leaves the agency's cash flow permanently uncertain.

The trap: no dispute process at all, so the client's only lever is to withhold the entire invoice.
The drafting minimum: a written objection window of 14 to 30 days, an obligation to pay undisputed amounts, and an agreed process for resolving the dispute, escalating to a director-level discussion and then to external resolution if needed.
The agency's point: make the dispute process mutual, so the client's obligation to raise objections promptly is matched by the agency's obligation to respond to them.

Clauses worth adding when the deal calls for them

The clauses above are the core of any payment section, but a few more earn their place when the deal calls for them:

Budget caps and estimates: for campaigns with significant third-party spend, cap the total the agency can commit without fresh client approval, and require a written estimate before each spend.
Price review: for long-running retainers, an annual adjustment clause linked to a published index, so the fee does not quietly become uncommercial and get renegotiated mid-project.
Travel and out-of-town expenses: if the work involves on-site shoots or client travel, state what counts as a travel expense and how it is approved, rather than folding it into general expenses.
Payment-linked IP: agencies should consider making the transfer of intellectual property conditional on full payment, and clients should check for it, because it decides who owns the campaign work if the invoice is never paid.
Set-off and withholding: an express clause confirming what the client can and cannot set off against fees, such as genuine claims but not disputed or unparticularised amounts.

How an Artificer Legal lawyer would review your payment clauses

Artificer Legal regularly reviews and negotiates creative agency agreements on both sides of the table. We would start with the definition of what the fee covers, because that is where most disputes begin, and check that the fee schedule, scope of work and revision rounds are all attached and consistent. We would push back on time and materials pricing with no cap, on standard rates from time to time wording, and on expense reimbursement clauses with no approval step. We would insist on a stated late payment rate that survives the penalty rule and the unfair contract terms regime, and on a dispute process that keeps undisputed amounts flowing. For agencies, we would make sure the invoicing triggers and suspension rights give real protection. For clients, we would make sure the due date is not tied to internal approval and that the scope of included work is closed. In negotiation we would deal with the price and scope clauses first, then payment timing, then the enforcement machinery, because the commercial deal should be locked before the protections are argued over.

Where fee disputes actually start

Most creative agency fee disputes are not about the numbers on the fee schedule. They are about the boundary between what was included and what was charged as an extra, and about who approved the spending. The clauses that decide those questions, the scope of included work and the prior approval requirement for third-party expenses, are the ones that make the difference between an agreement that works and one that ends in a standoff. Draft them as if a dispute is coming, because that is the only way to avoid one.

The rest follows from there: a fee structure that can be checked, invoicing triggers that protect the agency's cash flow, payment terms measured from the invoice, a late payment rate that is enforceable, GST stated clearly, and a process for disputes that keeps money moving while the argument is resolved. An agreement that covers those points gives both sides something the creative brief cannot: certainty about money.
