The short version
- Quote a structure, not a number. A deposit, milestone payments, a kill fee, a revision allowance and a usage layer each transfer a specific risk.
- The deposit is risk transfer, not cash flow. It covers materials, pays for preliminary work, and separates a serious client from a time-waster.
- Scope is defined at the start so creep is recognisable later. A stated revision allowance plus a change-order path is what makes that possible.

Deposit logic: the deposit as risk transfer
The core idea A deposit is a risk-transfer instrument. Before any deposit changes hands, the artist carries 100% of the project's risk — the client can vanish, change their mind, or refuse to pay, and the artist has already spent time, turned down other work, and possibly bought materials. The deposit moves a meaningful share of that risk onto the client, who now has money at stake and therefore an incentive to stay engaged.
What the deposit specifically protects against
- Material and setup costs. For physical work like murals, the deposit funds paint, supplies, and equipment so the artist isn't financing the client's project out of pocket. Maria Brophy, an art-business consultant who manages mural artist Drew Brophy's commissions, requires 50% two weeks before the start date specifically so she can "block out 5 or more days on the calendar (thus not accepting other projects for those days) and to purchase the necessary materials prior to the painting."
- Securing the slot (opportunity cost). When you reserve dates or queue position for one client, you turn away others. The deposit compensates that opportunity cost. A working portrait artist's reasoning captures it cleanly: a "non-refundable one-third deposit holds that commission's place in line to be started as soon as previous ones are completed."
- Signaling commitment / filtering. Brophy frames the deposit as partly "a psychological thing with your client — you want to train them to view you as a professional who expects prompt payment, and they are fully committed when they pay half up front." A client who won't pay a deposit is showing you, cheaply and early, that they may be trouble later.
- Protecting against ghosting. The deposit guarantees the artist is not left entirely empty-handed if the client disappears after work has begun.
Reasoning about the deposit percentage (50/50 vs thirds)
How artists reason about the percentage The two dominant mental models are 50% upfront / 50% on delivery and a staged one-third / one-third / one-third (signing / sketch approval / delivery). On the 50/50 norm, FramedFantasy's commission guide states plainly that "the most common approach in the world of freelance art is the deposit model, often a 50/50 split."
Tad Crawford's Business and Legal Forms for Illustrators (Allworth Press, published in the Graphic Artists Guild ecosystem) builds the staged advance directly into its model Confirmation of Assignment: "At the time of signing this Agreement, Client shall pay Illustrator _ percent of the fee as an advance against the total fee. Upon approval of sketches, Client shall pay Illustrator _ percent of the fee as an advance."
The professional muralist studio Vivache Designs states the clean one-third version: "A one third, non-refundable deposit is required upon the signing of the contract. A second payment of one third is due upon approval of the preliminary design and color study. The balance is due upon approval of the final portrait."
What pushes the percentage higher: a brand-new/unvetted client; custom or non-reusable materials (the less resaleable your inputs, the stronger the case for a bigger deposit); long lead times or a reserved block of dates; large material outlays. What pushes it lower: a trusted repeat client with a payment track record; small/quick jobs; situations where you want to reduce the client's perceived risk to win the work.
The non-refundable framing Artists frame the deposit as non-refundable because its entire purpose is to compensate work and commitment that cannot be recovered if the client cancels — the consultation time, the sketches, the reserved slot. As one professional artists' guide puts it, "a non-refundable deposit compensates the artist for their time and effort in the initial stages of the commission (communication, sketching, and securing a spot in their schedule)." Note that "non-refundable" is not a magic word — its enforceability depends on the amount being a reasonable pre-estimate of your actual loss rather than a penalty, which is precisely why this needs a lawyer.
Refer out The logic of the deposit is yours to set; the enforceability of the non-refundable language, and how it interacts with consumer-protection law in your state or country, is not. Have an arts attorney draft or review the deposit clause — including the non-refundable framing and what the deposit is stated to cover — before you use it.
Highest-leverage insightBefore a deposit changes hands the artist carries all of the project's risk; the deposit moves a meaningful share of it onto the person who commissioned the work.
Milestone payments
Milestones: stage money against visible progress, both directions
The core idea For any commission large enough that 50/50 leaves too much unpaid work exposed, break payment into installments tied to deliverable stages rather than calendar dates. The mental model is that money should track visible progress in both directions: you are never far ahead of your payment, and the client never pays far ahead of what they can see.
Why milestones reduce risk for both parties Staging "converts one large risk into several small ones." If a five-figure mural is paid only at the end, the artist risks the entire fee on the final handshake; if it's paid only upfront, the client risks the entire fee on the artist delivering. Milestones cap each party's exposure to a single stage. This symmetry is why clients accept milestone billing readily — it protects them too.
Illustrator Alvalyn Lundgren ties this to getting paid ahead: she bills "at various milestones (rather than dates) during a project. Billing at project milestones means I'm always paid up front."
How to tie payments to deliverable stages The natural gates in a bespoke commission map to the creative process:
- Concept / design approval (the idea is agreed) — often carried by a separate non-refundable design or sketch fee.
- Sketch / underdrawing sign-off (composition is locked).
- Final delivery / installation (balance due on completion, before files or originals transfer).
Illustrative structures only (these are abstract examples, not recommended market rates): a simple 50/50; a balanced one-third / one-third / one-third at signing, sketch approval, and delivery; or for larger work a front-loaded mural-style split such as a design fee, then a larger payment before painting begins, then a final balance on completion. Public-art and mural practice often extends this to five or six steps (proposal approval → drawings/maquette approval → materials → fabrication complete → installation → final acceptance) precisely because the projects are long and the risk per stage must be kept small.
A defensible milestone structure conceptually Each milestone is:
- Objectively recognizable (an approval, a delivered file, an installed wall — not "halfway done").
- Paid before the next phase of work begins.
- Documented with a deliverable the client signs off on.
The sign-off is what makes the structure defensible: it creates a contemporaneous record that the client approved each stage, which protects you if a later dispute arises.
Refer out Decide the milestone map and percentages yourself — they are pricing judgments. But the trigger definitions, what counts as "acceptance," and the consequences of a missed or delayed payment are contract terms. Have an arts attorney draft the milestone and payment-schedule clauses.
Highest-leverage insightStaging money against visible progress protects both parties symmetrically, which is exactly why it survives client scrutiny where a bigger deposit would not.
Kill fees: getting paid when the client cancels
The core idea and why it exists A kill fee (also called a cancellation or termination fee) answers the question the deposit alone cannot: if the client cancels mid-project for reasons unrelated to your performance, what do they owe? It exists because cancellation imposes real losses on you — the time already invested, the other work you turned away, and the slot you can't refill on short notice. Kill fees have been standard in publishing, advertising, and media for decades; as former magazine editor Theodore Ross describes the publishing origin, "kill fees are the partial payment, usually 20–25 percent of the total, that a writer receives if a magazine or website chooses not to run his or her story."
The Graphic Artists Guild's distinction The Guild's Contract Glossary (excerpted from the Handbook) separates two cases that a lay person lumps together:
- A cancellation fee "should be paid when the artwork satisfies the client's stated requirements, but the client decides, for reasons outside the artist's control, not to use it" (e.g., the article it was meant for got killed).
- A rejection fee "should be paid when the artwork does not satisfy the client's stated requirements" — causes that are, in theory, within the artist's control.
The Guild notes both should be paid, and that artists "generally negotiate the kill fee as a percentage of the agreed-upon fee for the finished piece," observing "a wide range of kill fees, from 20 to 100 percent, usually depending on the stage of completion of the artwork at the time the project is killed." That stage-of-completion driver is corroborated by PublishDrive's publishing glossary, which notes kill fees "range from 25% to 100%… higher kill fees may be paid for pieces that are closer to completion, while lower fees might apply for work in the early stages."
Kill fee vs work-completed vs deposit; rights revert on a kill
How the kill fee relates to work-completed and to the deposit. The governing logic is the further along the project, the higher the percentage owed — because more of your time is sunk and less of your reserved capacity can be refilled.
The Guild's own model Letter of Agreement language states it plainly: "Fifty percent (50%) of the final fee is due within 30 days of notification that for any reason the job is canceled or postponed before the final stage. One hundred percent (100%) of the total fee is due despite cancellation or postponement of the job if the art has been completed." (These percentages are illustrative of the Guild's model language, not a live rule you must adopt.)
Two relationships matter:
- Kill fee vs. deposit. The deposit is usually the floor of the kill fee — at minimum you keep what you've been paid. Cameron Foote's widely cited contract language invoices the greater of "all work completed up to the date of written notification, including expenses" OR "the amount of any advance deposit made for this project." The deposit and kill fee work together: the deposit guarantees a minimum recovery; the kill fee scales the recovery up as completion increases.
- Rights revert on a kill. A crucial, easily missed point: the Guild's model returns all rights and original art to the artist on cancellation ("Upon cancellation or kill all rights to the art revert to the Artist and all original art must be returned, including sketches, comps, or other preliminary materials"). The Guild separately warns that "if the contract does not mention a kill fee, there is no guarantee that one will be paid."
Conceptual framing of cancellation at different stages A common mental model is a sliding scale that decreases as a percentage of remaining value (because late cancellation hurts less — most of the work is done and mostly paid) but increases as a percentage of total value (because more is sunk). Either framing works; the point is to define stage-based trigger points up front so there's no argument later about whether a stoppage was an early kill or a late one. Some artists abandon fixed kill-fee percentages entirely in favor of "bill for all work actually completed plus expenses," which is more defensible because it tracks real loss rather than an arbitrary number.
Refer out The philosophy of the kill fee — that cancellation should cost the client something that scales with completion — is yours. The exact percentages, the stage triggers, the rights-reversion language, and whether your jurisdiction treats a steep fee as an unenforceable penalty are all legal questions. Have an arts attorney draft the cancellation/kill-fee clause.
Highest-leverage insightA kill fee answers the question a deposit cannot: what is owed when a client walks away mid-project, and it has to be agreed before there is a reason to use it.
Revisions & scope creep
Scope creep accumulates; defend by defining scope up front
The core idea Scope creep is rarely one big request; it "accumulates: an extra revision round here, a 'quick' landing page there." The defense is built before any work begins by defining scope precisely so you can recognize when a request falls outside it — and then having a pre-agreed, non-confrontational path (the change order) for handling the overflow.
Distinguishing included revisions from out-of-scope changes The key conceptual line is between a revision (refining something the client already approved, within the agreed direction) and a new direction (changing what was approved, or adding something never quoted). The Graphic Artists Guild's model revision clause draws exactly this line: "Additional fees will be charged for revisions made after [your standard] sketches, and for revisions reflecting a new direction to the assignment, or new conceptual input." One practitioner's working definition of "reasonable revisions": "You can't change what you previously approved and you can not ask for something more that wasn't in the estimate."
How artists define "scope" up front so creep is recognizable. A defensible scope statement quantifies and bounds the deliverables: the number of pieces, the size/format, the number of concepts presented, and — critically — the number of revision rounds included.
The mural practice of capping sketches illustrates the behavioral logic: Brophy limits sketches to a set number and charges per additional sketch because "when you do this, your client will be motivated to be very specific about what they want. If you don't limit the number of sketches, they will just go on and on with changes." The limit isn't about nickel-and-diming; it's about creating an incentive for the client to give clear direction.
The mental model for pricing additional revisions and change orders. When the ask grows, the professional move is to treat it as a normal, even welcome, business event rather than a confrontation. Lundgren reframes it: "I embrace scope creep, because it means more income for me!… I communicate the details of the additions and the additions fees and time in a written change order. I do nothing until the change order is approved." The mechanics:
- Stop, don't absorb. Do not begin out-of-scope work until the change order is approved. Quietly absorbing it trains the client to expect free work and weakens your position.
- Document the change order. the new request, the additional fee, and the impact on timeline.
- Price it at your standard rate, often plus a premium. ScopePilot's freelancer change-order guide recommends you "charge your standard hourly rate plus a 10–20% 'nuisance fee' to compensate for the disruption and administrative overhead" of re-opening a defined project (illustrative reasoning, not a fixed rate).
Refer out You set the revision allowance and the pricing logic for overages. The contract should formally define what counts as a revision versus a new direction, specify the included rounds, and establish the change-order mechanism and that out-of-scope work is billed separately. Have an arts attorney draft the revision and change-order clauses.
Highest-leverage insightScope creep accumulates in increments too small to refuse individually, which is why the defence is a scope defined at the start rather than a line held later.
Quoting the whole
The core idea A defensible quote is not a number you pull from the air; it is the output of a reasoning process that prices your labor, then layers usage on top, then wraps the whole thing in the protective structure (deposit + milestones + kill fee + revision policy). The four previous sections are the protective wrapper; this section is how you arrive at the number they protect.
The reasoning an artist walks through to arrive at a quote:
- Establish a labor/creation floor. Estimate the real time the project will take — "everything from emails to sketches," as illustrator Emmy Smith puts it — and cost it against the rate you need to run a sustainable practice (overhead, taxes, materials, profit, not just hours). This is the "base creation fee," analogous to the manufacturing cost of the art. For physical work this is often expressed as a per-square-foot or per-piece rate with a stated minimum (Brophy charges a minimum for small murals "because it's a lot of work and time to set up at a location").
- Add the usage/licensing layer (see below). This is frequently the largest lever and is priced separately.
- Adjust for project-specific factors. complexity, the client's size and the value the work delivers to them, exclusivity, and rush timelines. The guiding principle, per art director Tim Easley: "A piece that takes a day is worth more to Coca Cola than a lemonade stand, so charge accordingly."
- Wrap it in structure. set the deposit percentage, the milestone map, the kill-fee scale, and the revision allowance.
- Present it as a written proposal, with reductions (if you discount) shown as separate line items so the client sees the full value before any concession.
Usage rights & licensing as a pricing input (license, don't sell)
The single most important conceptual shift is that you license your work; you don't sell it. Copyright remains with the artist on creation unless transferred in writing. Therefore the same image can be quoted at wildly different prices depending on use — the PRINT Magazine illustration guide notes the reproduction right "legally transfers to a client only after final payment," and recommends this be flagged in the initial quote. The levers that move the usage fee:
- Scope of use: medium (one editorial spot vs. national packaging), territory (local / regional / national / global), and duration (a 6-week magazine run vs. perpetual brand use).
- Exclusivity: whether the client locks out everyone else, which "comes at a higher cost because you're effectively buying the illustrator's future earning potential."
- Buyout / work-for-hire: full transfer of rights should be priced at the top of the range because the artist surrenders all future income from the work. AIGA's guidance is to "give the client a checklist of different usage levels with associated fees" rather than silently bundling rights — and to designate "usage fees as a separate line item," because "many clients assume that because they are paying significant fees for your work, they are receiving full rights to use your work any way they want."
Integrating it all into one coherent number and structure The finished quote reads as: a total creation fee + a usage grant (specified by medium/territory/duration/exclusivity) + a payment schedule (deposit percentage on signing, milestone payments at named approval gates, balance on delivery) + a stated revision allowance with change orders for overflow + a cancellation/kill-fee policy that scales with completion + reversion of rights on a kill and conditioning of the rights grant on full payment. Each component closes a specific gap; together they make the quote defensible because every foreseeable contingency — late payment, cancellation, expanded scope, expanded usage — already has a pre-agreed answer.
Refer out (prominent) This is the section where the hand-off to counsel matters most. You assemble the pricing logic and the commercial structure — fee, usage scope, deposit, milestones, kill fee, revisions. An arts/IP attorney turns that structure into an enforceable agreement: the precise license grant and rights-reversion language, the payment and cancellation clauses, warranty/indemnity, and the conditions under which rights transfer. The Graphic Artists Guild itself, even when publishing model forms, repeatedly adds the caveat to "recommend enlisting the services of a legal professional." Hold the pricing model yourself; let the lawyer hold the contract.
Highest-leverage insightShowing the reasoning turns a negotiation about your price into a negotiation about their scope, which is the only version of that conversation you can win.
Recommendations
Build your quote in this order, every time:
- Price the labor floor first. Estimate true time (including admin and sketches) against a sustainable rate, or use a per-unit rate with a minimum. Never anchor on the client's budget before you know your own floor.
- Add usage as a separate line. Ask for a usage brief (medium, territory, duration, exclusivity). If the client is vague, price toward the higher tier and let them negotiate down. Quote a buyout at a premium.
- Set the deposit by client risk. Default to a substantial upfront share (50%, or a staged one-third); raise it for new clients, custom materials, and reserved date-blocks; lower it only for proven repeat clients.
- Map milestones to approval gates, not dates. Concept → sketch sign-off → delivery, each paid before the next begins, each documented with a client sign-off.
- State the revision allowance and the change-order rule in the same breath: "X rounds included; new directions and additions are billed via change order at [rate], approved before work resumes."
- Attach a cancellation policy that scales with completion and reverts rights to you on a kill.
- Send it as a written proposal, then route the structure to an arts attorney to convert into a signed agreement before any deposit is invoiced.
Benchmarks / thresholds that should change your approach:
- If clients always accept your quote instantly, you're underpricing — raise rates.
- If a project will run more than ~4–6 weeks, move from 50/50 to true milestone billing to keep per-stage risk small.
- If a client refuses both a deposit and a kill fee, treat it as information about the relationship before it starts — it is a meaningful red flag, not just a negotiation.
- If a request changes something already approved or adds something un-quoted, that is the line: stop and issue a change order rather than absorbing it.
- If the client's use expands (more territory, longer duration, new media, a buyout), re-open the usage fee — that's renewable income, not a favor.
Posture Hold the line calmly. Firmness on deposits, milestones, and change orders is not hostility; it is the behavior that trains clients to treat you as a professional and that keeps a thin-margin commission practice solvent.
Highest-leverage insightYou hold the pricing logic; an arts attorney holds the contract, and every structure here belongs in an agreement before it reaches a client.
Caveats & limits
- This is a pricing mental model, not legal advice, and not a rate card. Every dollar figure and percentage here is illustrative of how artists reason, not a recommended market rate. Your actual numbers depend on your experience, location, cost of living, medium, and demand.
- The contract is the lawyer's domain. Deposit enforceability, kill-fee percentages that could read as unenforceable penalties, rights-reversion and license-grant language, warranty/indemnity, and jurisdiction-specific consumer-protection rules all require a qualified arts/IP attorney. The recurring instruction throughout — "have an arts attorney draft or review it" — is the single most important takeaway.
- These are plural, tailorable options, not one prescribed method. 50/50 and one-third-thirds are both legitimate; fixed kill-fee percentages and "bill for work completed plus expenses" are both defensible; flat fees and per-unit rates each suit different commissions. Adapt the structure to the project in front of you rather than applying one template universally.
- Source mix. The strongest, most attributable material comes from the Graphic Artists Guild (Handbook excerpts, Contract Glossary, model Letter of Agreement), AIGA professional-practice resources, the Tad Crawford forms book, and named working illustrators/muralists. A good deal of online "commission pricing" content is marketing for invoicing tools or calculators; that material was used cautiously and only for widely corroborated reasoning, not for specific figures. The current (17th) edition of the Guild Handbook is print/paywalled, so some Handbook narrative could not be quoted directly — model-form and glossary language (publicly posted by the Guild) was used instead.
- Numbers drift; principles don't. Market rates, platform norms, and licensing conventions change over time. This guide deliberately captures the durable reasoning so it remains useful regardless of where rates sit in any given year.
