# Get the design first, build it later > A design only project gives you the screens, flows and visual style of your product without any programming. You receive files a developer can build from, and you can test the idea with real people before you spend more. Canonical: https://erdibuilds.app/help/design-only Last updated: 2026-11-06 (November 6, 2026) ## Why design first Changing a drawing is much faster than changing code. If you design first, you find unclear ideas, missing screens and awkward flows while they are still easy to fix. You can show the design to users, partners or investors, and developers can then give you better proposals because they see what you mean. - You have an idea and want to see it before you build it. - You need a clickable prototype (A mock version of the product where you can tap through screens, but nothing really works behind them) for a test with customers. - Your product works but looks outdated or confusing. - A developer is waiting for screens to build from. ## What to prepare **Bring what you have** - Goal and users: Who is it for, and what should they be able to do in a minute? - Key flows: The three to five journeys that matter, such as signing up or booking. - Inspiration: Examples of products, colours and styles you like or dislike. - Brand: Logo, colours and fonts if you have them. If not, say so. - Platform: Phone, web, both? This changes the screens. ## What you receive Agree on the deliverables before you start. Common ones are a map of all screens, wireframes for the structure, a visual style with colours and type, a clickable prototype and an export of the design files with the assets a developer needs. Ask for the files in a format you own and can hand to anyone. Unless both sides agree otherwise in writing on the platform, the rights to the result of a milestone pass to the client once that milestone is paid in full. ## How it runs in milestones Each milestone is funded before work starts and runs 1, 2, 3, 4, 6 or 8 weeks. Milestones are from 50 to 2,000 each in your project currency. Design lends itself well to milestones because each stage ends with something you can look at and judge. **Example design plan** | | What you get | Example timing | | --- | --- | --- | | Phase 1: Structure | Screen map and simple wireframes of the main flows | One milestone, for example 1 to 2 weeks | | Phase 2: Look and feel | Visual style and the first fully designed screens | One milestone, for example 2 weeks | | Phase 3: Complete and connect | All screens designed and linked into a clickable prototype | One to two milestones, for example 2 to 4 weeks | | Phase 4: Handover | Organised files and notes, ready for a developer | One milestone, for example 1 week | Example only: the weeks are for illustration. Developers set the length of each milestone in their proposal, and each real milestone runs 1, 2, 3, 4, 6 or 8 weeks. ## Questions to ask - Can you show me finished designs that went on to be built? - How do you decide between my ideas and what you recommend? - How many rounds of change are included in each milestone? - Do you think about what a developer can build in reasonable time? - Which tool do you use, and can I open the files myself? > Design that ignores how things are built can be expensive to implement. If you can, involve a developer early, even for a short review of the screens. When the design is ready, continue with [build something new](https://erdibuilds.app/help/build-new).

Not for the design itself. A short check by a developer before you finish is a smart idea, since it avoids screens that are hard to build. ### Can the same person design and build? Often yes. Some developers offer both. Others only design. Check the help types in the proposal to see what each offers. ### How do I know the design is ready for development? Every screen exists, including empty states and errors, the flows are linked, and a developer can open the files and measure everything without asking you. ### Who owns the design files? Unless both sides agree otherwise in writing on the platform, the rights to the result of a milestone pass to the client once that milestone is paid in full. Ask for the source files in a common format, not only images. ### Does design only include a logo? Only if you agree on it. Say clearly whether you want a logo or brand work, or only product screens. ## Related - [Hire a Developer to Build Something New](https://erdibuilds.app/help/build-new): Turn an idea into a working product.
