UI/UX Design Services
UI/UX design services for U.S. product teams: UX research, prototypes, design systems and conversion-focused interfaces, tested with real users before code.
UI/UX Design at HandsOnTech covers 5 scoped services: SaaS UI/UX Design Services, Mobile App UI Design Company, Dashboard & Admin Panel Design, UX Audit & Conversion Optimization, MVP Product Design Services. Each one is quoted as a fixed price after a free 48-hour audit, delivered in two-week sprints on U.S. business hours from our Sacramento, California studio, and available to businesses in all 50 states.
Use this page to find the right starting point. If you already know the outcome you need, open the matching service page below for scope, deliverables, timeline and the price range that goes with it. If you are still deciding, the free audit is the faster route: send your URL and the metric this project has to move, and we will tell you which of these 5 services actually applies, including when the honest answer is none of them.
Why most redesigns fail
Opinion-driven UI costs twice, once for the wrong design, again to fix what users refuse to adopt.
Stakeholder opinions win
Boardroom taste replaces user evidence. Launch day looks polished; week two shows drop-off nobody predicted.
Handoff breaks the intent
Figma files arrive without edge cases, states or accessibility notes. Engineering improvises, and your brand pays for it.
No baseline metric
Without a number to move (signups, completion, time-to-task) you cannot tell if the redesign worked.
What we design and deliver
Research-backed UX that engineers can build without guesswork.
User research & journeys
Interviews, session review and journey maps tied to the one metric this release must move.
Wireframes & prototypes
Clickable Figma flows tested with real users before a line of production code.
Design systems
Tokens, components and documentation so every screen stays consistent after launch.
Usability & WCAG 2.2 AA
Accessibility and task testing baked in, not a checklist bolted on at the end.
How we design products that ship
Four phases, two-week sprints, evidence at every gate.

AI development servicesWhat you can hold us to
Not adjectives, terms. Each of these is written into the engagement before you sign.
Fixed price, in writing, before work starts
You receive a written scope with milestones, deliverables and a delivery date within 48 hours of the free audit. No hourly creep, and no change order three weeks before launch.
You own everything on final payment
Source code, Figma files, content and analytics access transfer to you when the final invoice clears. No license fees, no vendor lock-in, and no platform you can only edit by paying us.
A 30-day bug warranty, in the contract
Bugs found in the first month after go-live are fixed free. It is a contractual term rather than a sales promise, and it is the reason we would rather ship correctly than ship early.

Which ui/ux design service do we need?
Start from the outcome, not the deliverable. Tell us the number this project has to move and we map it to one of these 5 services in the free 48-hour audit: SaaS UI/UX Design Services, Mobile App UI Design Company, Dashboard & Admin Panel Design, UX Audit & Conversion Optimization, MVP Product Design Services. If more than one applies we say which to run first and why, and if none of them fit we say that too.
Can we combine ui/ux design with other services?
Yes, and most engagements do. Design, build and growth run under one contract, one timeline and one team, so the designer knows what the SEO architecture needs and the growth lead inherits a site built to rank instead of a retrofit project. Combining is where the compounding happens, and it is the thing three separate vendors structurally cannot give you.
How are ui/ux design projects priced?
Fixed price, quoted in writing after a free audit and scope review, with milestones and a delivery date. No hourly creep and no change orders three weeks before launch. Budget range is worth sharing early, because a smaller budget and a larger one are different architectures for the same goal, not the same plan at two speeds.
How long does delivery take?
Marketing websites ship in 4 to 6 weeks. Web apps and AI dashboards take 8 to 12 weeks. Mobile apps take 10 to 16 weeks. Growth programs report their first meaningful movement inside 90 days. Your exact date is confirmed in the written scope before work starts.
Do you work with companies outside California?
Yes. We are headquartered in Sacramento, California and serve businesses in all 50 states, remote-first, with daily overlap on Eastern, Central, Mountain and Pacific time. On-site working sessions in major U.S. metros are available by arrangement.
What happens after the project ships?
Every build carries a 30-day warranty: bugs found in the first month after go-live get fixed free, in the contract. After that you can add maintenance, an SEO or AEO retainer, paid media management, or a dedicated specialist embedded in your team. None of it is mandatory, and you own everything either way.
