UI/UX Design Outsourcing

Last updated: November 11, 2026

Users decide in seconds whether a product feels easy or frustrating. Confusing sign-up flows, inconsistent screens and inaccessible components cost conversions and support time, and developers end up guessing when designs are incomplete. With UI/UX design outsourcing, a 360 Soft team handles user research, information architecture, wireframes and prototypes, visual design, design systems, usability testing and developer handover in Figma, as a project or as an ongoing design capacity. Teams work remotely, on-site or hybrid from Istanbul and typically start within 1–2 weeks. If you need designers embedded in your product team, see hire UI/UX designers; for other services, see all outsourcing services.

What is UI/UX design outsourcing and who is it for?

UX (user experience) design is about how a product works: understanding users, structuring content and designing flows that let people reach their goals. UI (user interface) design is about how it looks and feels: layout, typography, colour, components and interaction states. UI/UX design outsourcing means an external team takes responsibility for this work, from research to ready-to-build screens, in close collaboration with your product owners and developers.

It suits start-ups that need a product designed before or alongside development, SaaS companies redesigning an ageing interface, e-commerce brands optimising checkout and product pages, banks, insurers and public services digitising customer journeys, and enterprises that need a design system to keep many teams consistent. It also helps software agencies and development teams that lack in-house designers.

Scope of the service

Area	Typical deliverables
Research	Stakeholder interviews, user interviews, surveys, analytics review, competitor analysis, personas, journey maps
UX design	Information architecture, user flows, wireframes, clickable prototypes
UI design	Visual concept, high-fidelity screens for web and mobile, responsive layouts, dark mode
Design systems	Component libraries, tokens, documentation, Figma libraries aligned with code
Testing	Usability tests, A/B test concepts, heuristic evaluations, accessibility audits
Handover	Annotated Figma files, specs, assets, design QA during development
Content and micro-interactions	UX writing, empty and error states, motion specifications

Methods, standards and regulation

We work with design thinking and lean UX methods, follow platform guidelines such as Apple Human Interface Guidelines and Material Design, and design to WCAG 2.2 AA accessibility criteria. Accessibility is increasingly a legal requirement: the European Accessibility Act applies to many digital products and services sold in the EU from June 2025, and similar rules exist in the UK and US. User research involving personal data follows KVKK and, for international clients, GDPR, with informed consent and data minimisation. Local regulations in your country apply in addition.

Delivery models

Model	How it works	Best for
Design project	Defined scope, e.g. MVP design or redesign	New products, major redesigns
Dedicated design team	Designers working in your sprints	Continuous product development
Design sprint	Short, focused workshop and prototype cycle	Validating an idea quickly
Audit and improvement	UX and accessibility review with prioritised fixes	Existing products with known issues

Process and typical timelines

Discovery (1–2 weeks): goals, users, constraints, analytics and existing designs.
Research and concept (2–4 weeks): interviews, flows, information architecture, wireframes.
Prototype and test (1–3 weeks): clickable prototype, usability tests, iterations.
UI design and design system (typically 3–8 weeks): high-fidelity screens and components.
Handover and design QA: specs for developers and review of the built product.

Illustrative scenario

Illustrative scenario: a B2B SaaS company plans to rebuild its dashboard, which users find cluttered. A 360 Soft team interviews customers, maps the top tasks, tests a new navigation in a prototype with a handful of users and then designs a component library that the developers implement sprint by sprint, with design QA on each release. This is an example approach, not a reported client result.

SLA and KPI table

KPI	What it measures	How targets are set
Deliverables on time	Milestones delivered as planned	Project or sprint plan
Usability test success	Users completing key tasks	Measured in tests, compared to baseline
Accessibility compliance	Screens meeting WCAG 2.2 AA	Audit checklist
Design-to-dev handover quality	Questions or rework caused by unclear specs	Tracked per sprint
Design system coverage	Screens built from shared components	Tracked over time
Product metrics	Conversion, task time, support tickets	Defined with you, measured after release

Pricing factors

Factor	Impact on cost
Number of screens and platforms	Web, iOS and Android each add work
Research depth	Interviews and usability tests add time
Design system	Building a full library is a larger investment
Seniority	Lead and senior designers vs mid-level
Model	Project, dedicated team, sprint or audit
Languages and RTL	Multilingual and right-to-left layouts need extra design

We do not publish fixed prices; we provide an estimate after a short discovery call.

In-house team, freelancers or outsourcing?

Criteria	In-house	Freelancers	Outsourcing (360 Soft)
Skill range	Researcher, UX, UI often missing	One person, limited range	Combined team
Continuity	Turnover risk	Availability varies	Replacement process, documented files
Scaling	Slow hiring	Limited	From 1 designer to a full team
Collaboration with developers	Good if co-located	Varies	Sprint-based, design QA included

Risks and mitigations

Designs that cannot be built: early developer reviews and component-based design.
Designing on assumptions: research and usability tests before final UI.
Inconsistent screens: design system and design tokens.
Accessibility gaps: WCAG checks during design, not after release.
Lost files: work in your Figma organisation with version history.

Security, data protection, privacy and IP

Designers work in your Figma organisation or a workspace transferred to you. Unreleased products are covered by NDA. Research participants’ data is collected with consent and minimised. All designs, prototypes, research outputs and design system assets are assigned to you on payment.

A note on the contract model

We work under a B2B service agreement with a statement of work, SLA annex and change procedure. Intellectual property in deliverables (rules, reports, code, designs, documentation) is assigned to you on payment, and a mutual NDA is signed before any data is shared. Where we process personal data on your behalf, we sign a GDPR-compliant data processing agreement (DPA) with Standard Contractual Clauses, or the UK IDTA/Addendum for UK clients, and we operate under Turkey’s KVKK. Team members are employed by 360 Soft under Turkish labour law; we remain responsible for their management and replacement. This is general information, not legal advice; please have your counsel review the final contract.

Design partner selection checklist

Does the partner include research and testing, not just visuals?
Are accessibility standards part of the process?
Do they work in your tools and organisation?
Is there a design system approach?
How do they collaborate with developers and handle design QA?
Is IP assignment clearly stated in the contract?
Can they design for multiple languages, including right-to-left?

Frequently asked questions

What is the difference between UI and UX design?

UX design covers how a product works: users, structure and flows. UI design covers how it looks: layout, typography, colour and components.

Which tools do you use?

Mainly Figma, with FigJam for workshops, and research and testing tools agreed with you.

Do you do user research?

Yes. Interviews, surveys, analytics reviews and usability tests are part of the service.

Can you work with our developers?

Yes. We work in your sprints, prepare developer specs and review the built product.

Do you design for accessibility?

Yes. We design to WCAG 2.2 AA, which also supports European Accessibility Act requirements.

Can you build a design system?

Yes, including component libraries, tokens and documentation aligned with your code.
