UI/UX Design Agency for UK Software Teams

RAIN is a senior design and development studio in Casablanca, Morocco, working remotely with UK companies. We design the interfaces of complex software, such as B2B SaaS products, back-office tools, ERP and CRM systems, for UK teams that need a product designer who understands data models, permissions and edge cases, not just screens.

A UI/UX design agency for complex products

Most UI/UX design agency portfolios show consumer apps and landing pages. B2B products are a different problem. A sales operations tool or an ERP is used for hours a day by people who know the work better than the designer does. They care about density, speed, keyboard shortcuts and whether a table can show twelve fields without scrolling sideways.

We specialise in that kind of interface. In UK buyers’ terms, we fit best when:

• You are a B2B SaaS company whose product has grown feature by feature and now needs a coherent design system.
• You run internal tools or a back office that staff tolerate rather than use well.
• You are replacing a spreadsheet-driven process and need the new system designed before it is built. See bespoke software development for UK businesses.

Signs your product needs UX work

UK product teams usually call a UX design company when they notice one or more of these:

• Support tickets that are really design bugs: users cannot find a setting, misread a status or repeat the same task because the first attempt looked like it failed.
• Onboarding that depends on a person. New customers or staff only succeed after a call with your team.
• A design system in name only. Five button styles, three table patterns and colours chosen screen by screen.
• Features shipped but unused, because they sit behind menus nobody opens.
• Sales demos that avoid parts of the product. If your team steers around a screen, so do your users.

Each of these has a measurable baseline (ticket volume, time to first value, feature adoption), which lets us judge whether the redesign worked rather than whether it looks better. It also tells us where to start: the screens behind the most tickets usually come first.

Proof in shipped products

We can show complete products, not concept shots:

• RIVER ERP: 23 modules, 12 suites and 154 screens on one design system. Every feature is gated by a module system and role-based permissions, so a three-person shop and a multi-company group use the same build. Users can choose from nine colour palettes, and WCAG AA contrast for each is enforced by an automated test.
• Enterprise CRM: a B2B relationship tool that puts twelve data dimensions per account in a single row, including people, ARR, ICP score, tasks and opportunities, so reps stop switching tabs. It has native dark and light modes for long operator days and client-facing screens.
• RAIN Store: an e-commerce admin of 58 modules across 7 suites, with a plain-language AI alert layer that ranks stock, order and system issues when an operator logs in.

These are products we design, build and maintain ourselves, so the design decisions have been tested by real daily use rather than a client presentation.

Our product design process

1. Discovery. Stakeholder interviews, a review of analytics and support tickets, and moderated sessions with real users over video.
2. Flows and information architecture. The jobs users need to do, the objects they work with, and the permissions around them.
3. Wireframes and prototypes in Figma, tested with users before visual design is locked.
4. Design system. Tokens for colour, type and spacing; components with states, density options and accessibility notes.
5. Build handoff or build. Either a documented Figma library for your engineers, or production components in Vue 3 or React from our own developers.

Each step ends with something you can review on a Friday Loom walkthrough. More detail on deliverables is on our main UI/UX design agency page.

How UX agencies compare for UK buyers

Research depth	Strong	Moderate	Varies	Moderate, focused on the decisions at hand
Design system	Sometimes	Yes, in Figma	Varies	In Figma and in code
Builds the product	No	No	Rarely	Yes, same team
B2B and data-heavy interfaces	Varies	Varies	Varies	ERP, CRM, billing and e-commerce admin shipped

Time zone	UK	Varies	Varies	Same as UK or 1 h ahead

If you mainly need large-scale research programmes, a specialist research consultancy is a better fit. If you need research, design and a working front end from one accountable team, that is what we do.

Accessibility and UK expectations

UK public sector websites and apps must meet the Public Sector Bodies Accessibility Regulations 2018, and private businesses have duties under the Equality Act 2010 not to exclude disabled users. WCAG is the usual yardstick in both cases. We design to WCAG 2.2 AA as a working target:

• Contrast checked at the token level, so every component inherits it.
• Full keyboard paths and visible focus states for every interactive element.
• Semantic components that work with screen readers.
• Density options for data-heavy screens without shrinking touch targets on mobile.

We do not issue legal compliance certificates. If you need a formal audit, we will work alongside your chosen auditor.

Working with UK product teams remotely

• Hours. Casablanca is on GMT+1 most of the year and GMT for about a month around Ramadan: the same as the UK in summer, one hour ahead in winter. Design reviews happen in your working day.
• Tools. Figma, your issue tracker and one shared Slack channel. We work inside your Figma organisation if you prefer.
• Workshops. Remote by default; in person at your office by arrangement.
• Ownership. Figma files, components and code belong to you, as written in the contract.
• Data. For research sessions with UK users we agree consent, recording and storage with you, with UK GDPR in mind.

Timeline and pricing

• Design sprint or audit of an existing product: scoped as a fixed project from $10,000.
• Ongoing product design: Growth retainer at $7,500 per month for 45 hours, two active projects and twice-weekly syncs.
• Design and development together: Scale retainer at $15,000 per month for 100 hours and daily syncs.
• Kick-off within 3–5 business days of signature.
