How to Invoice as a 3D Artist: Rates, Terms and Templates

Three-dimensional artists deliver models, textures, lookdev, animation, or real-time assets. Clients often scope poorly—your invoice should map to milestones (blockout → high-res → approved delivery) and revision rounds defined in writing.

Engine-specific deliverables (Unity, Unreal) deserve explicit filenames and formats on the bill or attached delivery sheet.

Studios rotate producers; when your invoice reads like a release checklist, the next person picking up the project knows what was already paid for and what is still open.

Typical rates

Hourly for R&D-heavy work; fixed milestones for game or product viz pipelines; day rates for studio embeds. Rendering farm costs as pass-through or marked-up—label clearly. Khronos glTF resources illustrate why standard formats reduce rework—external anchor when clients demand proprietary-only pipelines that slow you down.

Rigging and simulation are different skills—split lines when you provide both.

Lookdev iterations after approved concept art sometimes need separate caps—note overage rates on the invoice when rounds exceed the SOW.

Sample invoice line items

When to send the invoice

For milestone-based projects, invoice at each milestone sign-off: after blockout approval, after high-res model delivery, and after final files and formats are handed off. Do not advance to the next milestone until the current invoice is paid -- this protects both parties.

On hourly or day-rate studio embeds, invoice weekly or biweekly with a task summary pulled from your time tracker or project board. Include the ticket or task references so producers can cross-check.

For asset packs and library work (game props, architectural models), invoice 50% at kick-off and 50% on delivery. If the pack is large (20+ assets), add a mid-point progress draw to keep cash flow aligned with production.

Payment terms

Deposit (30%–50%) before heavy modeling; progress invoices per milestone; final on approval or Net 15 for reputable studios. Kill fees for canceled phases belong in contracts and partial invoices when triggered.

Purchase orders from big clients—reference PO number every time.

Indie teams may use smaller weekly slices instead of huge milestones—steady cash flow beats heroic crunch with one giant unpaid deliverable.

What to include

Project and asset list, milestone name, file format summary, hours if hourly, revision round number if billing overage, tax if applicable, total, due date. Use how to write an invoice for identifiers and numbering.

Link to delivery folder or version tag in memo for audit trails.

Pair with invoice must-haves when billing through vendor portals that reject PDFs missing tax IDs.

Common mistakes

Unlimited revisions for a flat—scope death spirals. Combined modeling and texturing when only one was approved—disputes. No definition of “final”—invoice against signed approval emails. Farm costs surprise clients—estimate early.

NDA prevents portfolio use—do not promise marketing usage on invoices.

Asset handoff without license line (“client owns final mesh per SOW”)—legal and finance interpret silence differently.

Lookdev references pulled from paid asset libraries need license pass-through or client-owned entitlements spelled out—otherwise someone assumes you indemnified every texture forever.

Industry rate benchmarks (2026)

3d art and rendering rates vary by experience, geography, and specialization. Working ranges from CG Society + ArtStation 2025 freelancer rates survey:

Premium factors: certification or specialized credential typically adds 20-40%, demonstrated portfolio with case studies adds 15-30%, top-quartile metro markets command 25-50% above national median.

Step-by-step: Sending your first 3D art and rendering invoice

Step 1: Decide your billing model — package, retainer, or per-project

Three workable patterns: per-project (simple, but creates many small invoices), package (3-12 sessions/projects sold upfront, locks commitment), or monthly retainer (ongoing engagement at fixed monthly fee). Pick one consistent model per client; don't mix.

Step 2: Take a deposit on first engagement

First-time clients without referrals: 25-50% deposit on signing. The deposit protects against cancellation costs (you've blocked time / ordered materials / declined other work). State on invoice: "Deposit non-refundable. Remainder due [date or milestone]."

Step 3: Itemize deliverables, not just totals

Bad: "3d art and rendering services — $X". Good: line-item every distinct deliverable, hour, or session with its own rate. Itemizing reduces dispute frequency and helps clients expense the invoice correctly.

Step 4: Define cancellation and revision policies on the invoice itself

Don't bury terms in a separate contract you wrote 6 months ago. State on every invoice: cancellation window, revision rounds included, what triggers additional fees. Visibility is your protection.

Step 5: Send a follow-up reminder if not paid within terms

Day 1-3 after due date: gentle reminder. Day 14: firm follow-up. Day 30+: stop work + formal demand. Late 3D art and rendering invoices are about prioritization, not unwillingness to pay — reminders work in 70%+ of cases.

Common 3D art and rendering billing scenarios

Established repeat client: After 3+ engagements, offer a 5-10% loyalty discount on packages. State on invoice: "Loyalty pricing applied (returning client)." Locks in the relationship and signals you value them.

Last-minute booking: Charge 20-30% rush premium for sub-7-day bookings. State on quote/invoice: "Expedite fee for short-notice booking." Most clients accept this as fair.

Scope expansion mid-project: Don't absorb scope creep silently. Issue a Change Order invoice with the new work and pricing, get written approval before proceeding. "Add'l scope per 4/15 email — $X. Please confirm to proceed."

Refund request after delivery: Honor genuine workmanship issues; decline change-of-mind refunds. Document with photos/files. Pro-rate refunds where appropriate (e.g., 5 of 10 package sessions used = 50% remaining refundable minus 15% admin fee).

Frequently Asked Questions

Should I charge sales tax on 3D art and rendering services?

This varies by state. In service-friendly states (CA, NY, FL, IL — most of the country), pure services are exempt. In a handful of states (TX, CT, NJ, OH, WV), specific service categories are taxable. Verify with your state Department of Revenue and state your tax policy on every invoice.

What's the right deposit for a 3D art and rendering project?

25-50% is standard. Higher deposits for first-time clients without referrals; lower deposits acceptable for repeat clients with track record. Below 25% means you're carrying too much risk; above 50% can scare new clients.

How do I handle a client who delays feedback or scheduling?

Build pause clauses into every engagement: "If feedback/scheduling not received within X days, project pauses. Restart fee: $Y to resume." Without this, clients leave projects in limbo for months while you can't fill the slot with paying work.

Can I refuse service if a client tries to negotiate price?

Yes, and confident professionals do. Negotiating clients typically dispute deliverables after the fact, tip poorly, and refer fewer (or worse) clients. Set rates with conviction; politely decline to lower them. The clients who respect your pricing are the ones worth keeping.

What's a fair late-payment policy?

1-1.5% per month late fee (12-18% annualized) is standard and enforceable in most states. State on every invoice: "Payments due Net 14. Late fee 1% per month after 30 days." Without explicit terms, you can usually only collect statutory interest (varies by state).

Our 3D artist invoice template fits milestones, hourly blocks, and expenses.

Reuse the same milestone names as your task tracker so producers can map invoices to boards in seconds.

Messy client CAD that needs cleanup before you can model deserves a “data prep” milestone or hourly discovery—otherwise you absorb engineering debt before the first pretty render.

FAQ

Should I charge for file-format conversions (FBX, glTF, USDZ)? If the SOW specifies the formats, include conversion in the milestone price. If the client requests additional formats after delivery, charge per format or per batch as a change order. Note each format on the invoice so the client's tech team knows exactly what was delivered and can verify compatibility.

How do I handle revision rounds that exceed the scope? Define included revision rounds per milestone in the contract (e.g., "2 rounds of revisions at each milestone"). Bill additional rounds at your hourly rate as a separate invoice line. Reference the SOW clause and the approval that triggered the extra work.

What if the client's concept art or reference changes mid-project? Issue a change order before reworking the asset. Show the original milestone scope and the new direction as separate line items on the invoice. This documents the pivot and prevents the client from expecting the rework at no additional cost.

Engine exports named in the SOW (USDZ, glTF, FBX) should match invoice line labels so approvers tie PDFs to tickets. Post-final lighting tweaks belong on a change-order bill—not unlimited free polish.
