Learn how milestone payments work in commissions, protecting both artists and clients with phased payments tied to deliverables.
Two failure modes most artists hit.
You ask for 100% up front. Smaller commissions, fine. Bigger ones, the client balks. The trust they need to drop $1,200 on someone they've never worked with isn't there yet, and you lose the booking.
You ask for 50% up front, the rest on delivery. The client pays the deposit, you do the sketch and a clean version, and they vanish at the lineart stage. You've done half the work for a quarter of the money, you can't reach them for the rest, and the commission rots in your queue while you wait it out.
Milestone payments fix both. The structure is straightforward, the splits are not as complicated as they sound, and once it's set up the work-to-payment ratio stays balanced through the whole project. This is the actual breakdown.
A milestone payment structure splits the total commission price into multiple smaller payments tied to specific delivery phases. Instead of paying once at the start or once at the end, the client pays a portion at booking, additional portions at each phase you complete, and the final portion at delivery.
Each payment opens the next phase of work. Each phase ends with a deliverable the client can sign off on. The signoff triggers the next payment. The next payment starts the next phase.
The structure protects both sides. The client is never paying for work they haven't seen yet. You're never doing significant work without being paid for the work that came before it.
The client's worry on a large commission is that they pay everything up front and then disappear into the artist's queue, unable to verify progress, with no recourse if things go sideways. A milestone structure means they pay incrementally based on actual delivered work. If they're not happy with the sketch, they've paid 30% and they can walk. If they ghost at lineart, you've been paid for the sketch and lineart phases and you stop work.
Your worry on a 50% upfront commission is that the client disappears after the deposit covers the sketch and you've done significant work without payment. A milestone structure means the work you've done is always covered by the payments that have released. If the client disappears at lineart, you've been paid for sketch and lineart. The project ends, you're not owed anything you haven't been paid for.
The reason this works for both sides at once: at every gate, the risk is bounded. Neither party has more exposure than one phase of work. The total project can be large, but the unit of risk at any moment is small.
This is the same logic that makes milestone structures the standard on vtuber commissions, where the deliverable comes in clear phases (design, expressions, rig) and the project value is high enough that 100% upfront isn't going to happen.
A few common structures.
30/30/40 (three milestone). Booking and sketch, lineart and color base, final delivery. The most common structure for character art and full illustrations. Lines up with how most artists already work, just with payment gates between the phases.
25/25/25/25 (four milestone). Booking, sketch, lineart, final. Adds a phase but spreads the risk further. Useful when the project is large enough that 30% feels like too much exposure at the sketch stage, or when the work has a natural fourth phase (rendering, background, polish).
50/50 (two milestone). Booking, final delivery. The lightest version. Better than 100% upfront for the client, better than 50/50 with no intermediate signoff for you. Use it when the project is small enough that more than two phases would feel like overhead.
40/30/30. Front-loaded. Useful when the design phase carries more of the work than the lineart or final. Common on character design commissions where the design itself is the hard part and the cleanup is comparatively straightforward.
30/20/20/30 (vtuber or staged delivery). Booking, design approval, expression set, final. The structure for projects with distinct deliverable phases where each phase is a meaningful gate.
Pick the structure that maps to how the work actually flows. The percentages aren't sacred. What matters is that each payment ties to a real deliverable and that no single phase represents more work than the payment for it covers.
Studio Queues lets you set the splits at intake without committing to one fixed structure across all projects. Different commissions get different splits depending on what fits the work. A character portrait might be 30/30/40, a vtuber package might be 30/20/20/30, a quick badge commission might be 50/50. The platform handles the math and the releases regardless of which structure you pick.
The principle that keeps the structure honest: every milestone payment releases when a specific deliverable is signed off, not when an arbitrary date hits.
For a typical character commission:
For a vtuber commission, the phases shift: design approval, expression set, rig (if included), final handover. For a multi-character piece, the phases might be character 1 sketch, character 2 sketch, color, final. Whatever the project structure is, the rule is the same: payment ties to a deliverable, deliverable ties to a signoff, signoff triggers the next phase.
The signoff is what makes the structure actually work. If you deliver a sketch and the client says nothing for two weeks, the project stalls but no payment releases. If they sign off and you move forward, the payment is released and you're protected on the work you're about to do. The signoff is also what gives you delivery evidence for chargeback disputes if one ever comes through. The acceptance is recorded at each phase, not just at the end.
The biggest reservation artists have about milestone payments is that clients will react badly to "multiple payments" as if it sounds extractive. The framing matters.
The phrasing that works in your intake form or commission page:
"Payment for commissions is structured in phases. A booking payment confirms your slot and starts the work. Additional payments release at the sketch approval and final delivery stages. This structure protects both of us: you're never paying for work you haven't reviewed, and I'm never doing significant work without compensation for the previous phases."
That's it. The framing is "we both benefit," not "I'm protecting myself from you." Clients who would have been fine with a 50/50 structure are fine with a milestone structure when it's presented as standard practice. Clients who would have been a problem with any structure often surface their problems at the intake stage when they see the milestone breakdown, which is itself a useful filter.
Avoid framing this as a response to bad past clients ("this is because some people have ghosted me"). Avoid apologizing for it. Avoid offering to skip it if the client asks. The structure is what you do. It's the same answer for everyone.
The intake form guide covers where this fits in the broader form structure, alongside the click-to-accept TOS and the scope questions.
The manual version of this is possible. It's also painful.
The manual setup looks like this:
Every piece works. Together they're a fragile stack. Invoices get sent late. Clients sign off in Discord and you forget to mark the signoff in your tracker. The TOS version that was live at booking isn't the same as the one at delivery and you can't prove which one applies. The records exist but they're scattered.
Studio Queues handles the splits and signoffs as part of the platform you're already using to manage the commission. You set the milestone splits and the signoff requirements at intake (the splits are part of the form your client fills out). The payments release at each phase as the signoff happens. The TOS click-to-accept is recorded with the intake. The signoffs are recorded with the commission. There's no separate stack to maintain because the platform is the stack.
For artists doing more than a few commissions a month, the manual setup eats hours per project in invoice generation and tracker maintenance. For artists doing one or two a year, the manual stack is fine. The decision point is somewhere in between, and you usually realize you've crossed it after the third commission where the spreadsheet didn't match what actually happened.
Milestone payments are the right default for any commission over a few hundred dollars and for any project with distinct delivery phases. They protect the client, they protect you, and they make the chargeback exposure on any single transaction small enough to not matter much.
The structure is simple: split the price into phases that map to real deliverables, gate each payment release on a signoff, present it at intake as standard practice. Studio Queues handles the splits and signoffs as part of the workflow you're already running, so the structure is just there. Build it yourself with invoices and a spreadsheet if you'd rather, the layers are not exotic, but the maintenance is real and the records are usually scattered. Either path works. The path that doesn't work is sticking with 100% upfront or 50/50 deposits on jobs that are large enough to make either side nervous.
Set the milestones once. Run every project through them. The questions about deposits and refunds and "when do I pay the rest" mostly stop coming up, because the answer is the same on every commission.
