UI Design Deliverables Checklist: Source Files, Components, Specs, and Developer Notes

At project acceptance, the interface appears complete. Then developers open the file and find inconsistent page names, components without variants, icons of unknown origin, and missing modal states. The design itself may be finished, but it has not been organized into executable assets.

The delivery checklist should be written into the scope at the start of the project and reviewed against files and rules at the end, not explained verbally by the designer.

01 Page Source Files and Final Versions

Store final pages together, name them clearly, and map them to the page matrix. Separate explorations, rejected directions, and historical versions so developers do not use them accidentally.

The client should receive editable access and ownership of the file rather than remain dependent on a read-only link.

02 Critical Workflows and Interaction States

Cover login, forms, payment, filtering, modals, loading, errors, empty data, permissions, and success feedback. Provide a prototype, flowchart, or interaction notes for complex workflows.

Delivering only the happy-path pages pushes product decisions onto developers.

03 Component Library and Design Variables

Buttons, inputs, navigation, tables, cards, and modals should use components and variants, while color, typography, spacing, and corner radii should use shared variables.

The component library does not need to maximize quantity. What matters is reuse on real pages and understandable naming.

04 Responsive and Platform Rules

Define breakpoints, layouts, and content priorities for desktop, mobile, tablet, or different platforms. Representative designs and rules may cover repeated pages.

Do not deliver "responsive" as a phrase without a design basis.

05 Assets, Icons, and Fonts

Deliver icons, illustrations, images, and export specifications and record third-party sources and licenses. For fonts, explain the family, weight, use, and whether the client must purchase a separate license.

Displaying correctly on a designer's computer does not mean the client and developer may use it legally.

06 Developer Notes and Acceptance Support

Explain complex motion, data rules, truncation, responsive behavior, component states, and edge cases. Designers should participate in implementation reviews to confirm that the live product matches the design.

File delivery is not the end of the project relationship. At minimum, define a mechanism for questions and corrections.

Frequently Asked Questions

Does a Figma Link Count as a Source File?

It can if it is editable, ownership is clear, and it contains the final content. A read-only link or a file under an individual's account is not a complete delivery.

Does Every UI Project Need a Component Library?

Medium and large projects should include one. A simple campaign page may use foundational styles, but they must still be consistent and understandable.

Should Designers or Developers Export Assets?

Teams can decide according to their workflow. Design should provide export rules, formats, and any special assets.

Can Font Files Be Given Directly to the Client?

It depends on the license. Explain the font and licensing terms; do not casually copy restricted files.

Are Implementation Reviews Included in the Design Fee?

The contract should define the number and scope. Unlimited support should not be assumed.
