UX/UI designers are freelancers and small studio owners who design websites, mobile apps, and software products for startups, agencies, and established businesses. Invoices typically cover research, wireframes, visual design, prototyping, design systems, and developer handoff, billed by project phase, hourly, or on a monthly retainer.

Most UX/UI designers price in one of three ways: hourly for open-ended or small work, fixed fees per project phase for defined deliverables, or a monthly retainer for ongoing product design. Fixed-fee projects are usually split into phases such as discovery and research, wireframes, UI design, prototype, and handoff, with a set number of revision rounds included. Day rates are common for embedded contract work with a product team. Deliverables like design systems or usability test rounds are often priced as separate line items. Stock fonts, icon sets, stock photography, user testing platform fees, and participant incentives are usually passed through at cost or with a small markup. Work beyond the agreed scope is billed hourly as a change order.

Notes: Phase 2 of 3 per proposal dated March 4. Payment due within 14 days of invoice date. Late balances accrue 1.5% per month. Final design files and source files transfer upon payment of the final invoice. Accepted by ACH, check, or card.
Design projects run in stages, and the client needs to match each invoice to a milestone in the proposal or statement of work.
Listing items such as wireframes, a prototype link, or a design file shows what was delivered and reduces disputes about what was paid for.
Clients often lose track of how many rounds they have used. Showing it justifies any out-of-scope hours billed.
Time-based charges are the most questioned, so dates and brief task descriptions help approval.
Itemizing out-of-pocket expenses at cost keeps them separate from your fee and lets the client reimburse you cleanly.
Larger companies and agencies often cannot pay without a PO number or internal reference on the invoice.
Stating when rights to final files transfer, usually on full payment, protects you if a client delays payment but starts using the work.
Freelance designers commonly collect a 30 to 50 percent deposit before starting, then bill the remainder at milestones such as approval of wireframes, UI design, and handoff. Net 14 or net 15 is common for small clients, while larger companies may insist on net 30 or net 45. Retainers are usually billed at the start of each month. Late fees of 1 to 1.5 percent per month are typical if stated in the contract. Many designers hold final source files until the last invoice is paid. Payment is usually by ACH, card, or check, and international clients often use wire transfer.
Billing at milestones such as wireframe sign-off keeps cash flowing and prevents a project from stalling with most of the work done and little paid.
Define how many rounds are included at each phase and the hourly rate for extras. Scope creep in design usually shows up as endless small tweaks.
Clients often see only the pretty screens as the work. Listing discovery, research, and testing as their own line items shows where the value comes from.
Participant incentives, font licenses, and plugin fees can add up. Include receipts or list them on the next invoice so they do not get forgotten.
Handing over editable files and handoff specs is your leverage. Make the final payment condition clear in your agreement.
Use a fixed fee when scope and deliverables are clear, since clients like predictability and you are rewarded for working efficiently. Use hourly or a day rate when the scope is unclear, requirements are likely to change, or you are embedded with a product team.
Refer to the revision limit in your proposal and add a separate line for the extra work at your hourly rate, with dates and hours. Telling the client before you cross the limit prevents surprises.
Yes, it is standard. Many designers ask for 30 to 50 percent upfront, which covers the discovery work and confirms the client is committed.
Include a defined handoff, such as annotated files and one developer walkthrough, in the fee. Ongoing developer support during build is better billed hourly or under a retainer.
It depends on the state. Some states tax digital or professional services and many do not. Check with your state revenue department or a tax professional, and if tax applies, show it as a separate line.
