Interface design for complex software.

Most collaborations begin with a focused interface exploration and grow into a complete system as the product evolves.

Below are the typical ways teams work with me and the investment ranges.

Interface Foundations

Shaping the first interface for a complex tool, plugin, or software product.

£4k–£6k

Scope

Core interface concept

Primary plugin or product interface

Workflow refinement

Component logic defined

Production-ready UI files

Timeline

1-2 weeks

Product Interface System

Building a complete interface system

for a production-ready product.

£12k–£20k

Scope

Complete interface system

Interaction states and UI logic

Multi-format layouts (VST / AU / AAX)

Reusable components

Developer-ready handoff

Timeline

2-4 weeks

Design Partnership

Ongoing collaboration as an interface system evolves across releases.

£12k–£18k / month

Scope

Ongoing interface system evolution

Feature expansion

Visual iteration

Priority collaboration

Multi-format layout (VST / AU / AAX)

Timeline

Rolling Monthly

Exact scope and pricing are defined after a short discovery call.

What's Included

Regardless of which tier you choose, you get:

Final pricing depends on project complexity, timeline, and scope. We'll nail down specifics on our call.

Production-ready Figma files

Organised components & design tokens

Unlimited async communication during the project

Post-delivery support for implementation questions

Developer handoff documentation

Common questions.

What if I need more work than we agreed?

What if I need more work than we agreed?

We can extend the work with an additional sprint or project phase. Each phase is scoped clearly with its own timeline and investment, so projects can expand without losing momentum.

How quickly can you start?

How quickly can you start?

Typically within 1–2 weeks, depending on current project commitments. I’ll confirm availability during our call.

How many revisions are included?

How many revisions are included?

Foundation includes two revision rounds. System projects typically include two to three rounds. This keeps the process focused and prevents endless back-and-forth. Additional iterations can always be scoped if needed.

Do you offer ongoing support or retainers?

Do you offer ongoing support or retainers?

Yes, see the Design Partnership tier above. It’s ideal for teams shipping multiple releases or evolving an interface system over time.

Do you handle development too?

Do you handle development too?

No. I focus purely on interface design. You’ll receive production-ready Figma files organised for developers to build from immediately. For certain web projects, I can also provide Framer builds.

No, but I deliver production ready Figma files your developers can build from immediately. For web projects, I also offer Framer (no-code) builds.

Can you handle copywriting or branding?

Can you handle copywriting or branding?

No. I focus purely on interface design. You’ll need to provide copy and brand assets, but I ensure they are used clearly and effectively within the product.

How is project pricing determined?

How is project pricing determined?

Pricing depends on product complexity, scope, and timeline. The ranges above reflect typical engagements, but final investment is defined after a short discovery call where we review the product and goals.
