What Does a UI/UX Design Agency Actually Deliver? The Complete Deliverables List
Research, flows, wireframes, every screen state, a prototype, a design system and developer handoff — here's the full list of what a UI/UX agency should deliver, phase by phase.
A UI/UX design agency typically delivers research findings, user flows, wireframes, high-fidelity screen designs for every state, a clickable prototype, a design system or component library, and developer-ready handoff files — usually in Figma. Studios that also build will deliver working code on top of that. By the end of a project you should own the editable design files, not just images or a PDF.
What follows is the full list, organised by project phase, so you can check any proposal against it.
What are the deliverables at each phase?
| Phase | Deliverables | Why it matters |
|---|---|---|
| Discovery | Brief summary, goals and success metrics, competitor review, user or stakeholder interview notes | Aligns everyone on the problem before anything is drawn |
| UX structure | Sitemap or information architecture, user flows, user journeys | Defines how people move through the product |
| Wireframes | Low-fidelity layouts of key screens | Tests structure and content cheaply, before visual design |
| UI design | High-fidelity screens for mobile and desktop, in every language required | What the product will actually look like |
| States | Empty, loading, error, success, and edge cases | The part most often skipped — and where products feel broken |
| Prototype | Clickable Figma prototype of the key flows | Lets you test and present before development |
| Design system | Colours, type, spacing tokens and reusable components | Keeps the product consistent and faster to extend |
| Handoff | Annotated specs, exported assets, component documentation | Lets developers build it exactly as designed |
Not every project needs every item. A landing page may skip research and a full design system; a new product or platform should include almost all of them.
What should the final files include?
- The editable Figma file (or equivalent), transferred to your account or team
- All screens at mobile and desktop sizes — and tablet if relevant
- Arabic and English versions if the product is bilingual, designed right-to-left and left-to-right
- Icons, illustrations and images exported in web-ready formats
- Fonts and licences listed, so you know what you are allowed to use
- A component library your developers can map to code
Deliverables that are often missing
If the proposal lists "UI design — 20 screens" and nothing else, ask what happens to the error states, the empty screens and the Arabic version.
- Empty and error states. What a user sees with no data, or when something fails.
- Responsive behaviour. How layouts adapt between phone, tablet and desktop.
- RTL layouts. A real Arabic design, not an assumption that developers will flip it.
- Interaction notes. How menus open, what animates, what is tappable.
- A handoff session. A walkthrough with your developers, not just a link.
Does a design agency deliver code?
A pure design agency usually does not — it hands off to your developers. A design and development studio delivers both, which removes the handoff gap where details get lost. If you have no in-house developers, working with a team that does both usually costs less in total than hiring two separate vendors and coordinating them.
Who should own the files?
You should. Agree in the contract that ownership of the design files, assets and — if built — source code transfers to you on final payment. Ask for the Figma file to be moved to your own workspace, not shared as view-only.
What Flowlix delivers
Flowlix, a product design and development studio in Ismailia, Egypt, delivers research, flows, wireframes, high-fidelity UI in Arabic and English, clickable prototypes, a design system in Figma, and — because the same team builds — production code for websites and web and mobile apps. Clients own their Figma files and code on completion. Flowlix works with clients across Egypt, Saudi Arabia and the Gulf.
Frequently asked questions
How many screens does a typical app design include?
It depends on the product. A focused MVP may need a few dozen screens once every state is counted; a larger platform can run into the hundreds. Count flows and states, not only pages.
Is a prototype the same as an app?
No. A prototype is a clickable simulation made in a design tool — useful for testing and pitching, but it has no real data or logic. The app is built in code afterwards.
What should I give the agency at the start?
A clear brief: your goals, audience, key features, examples you like, brand assets and budget range. See our guide on how to write a design brief for an agency.
