Custom CRM development in London
London business.A CRM built around yours.
A founder-led product design and software studio for companies that need their relationship and operational systems to work as well as the business they are building.
The short answer
Custom CRM development in London
Wall & Fifth scopes and builds custom CRM software for London businesses, with engagements starting from £50,000. The work combines product design, a business-specific data model, workflow engineering, integrations, migration and reviewable agents. Delivery format, meetings and client responsibilities are agreed in the proposal.
For London teams
A specialised operation deserves a considered system.
London companies often work across teams, territories and partner organisations. An agency may connect talent with brands and bookings. A services firm may move an enquiry between commercial and delivery teams. A property or construction operation may need clients, sites, jobs and suppliers to stay connected.
The useful starting point is the daily workflow, not a sector label. We map the records, handovers and permissions that determine whether work moves forward. Then we design an interface that gives the relevant person the context and next action they need.
We are a London-based, founder-led product design and software studio working with UK and international businesses. Direct involvement in product direction, design and delivery keeps decisions close to the people building the system. We agree the delivery rhythm, stakeholder meetings and workshop arrangements with your team.
What we build
Relationships, workflows and agents in one scope.
The core CRM work includes the agreed record model, views, lifecycle stages, ownership and tasks. Integrations connect the relevant platform, accounting, email or other systems where access and APIs support the requirement. We define the boundaries before pricing the work.
Agents prepare briefs, follow-up drafts or proposed tasks from permitted context, with specific responsibilities and review steps. We implement and verify the connections, record types and allowed actions needed by the agreed workflow.
We choose the architecture against the requirements, including independently built software or suitable reusable components. Meibo is our own CRM product in development; any use of its core and the associated ownership terms are explicit in the proposal.
Scoping the project
Bring the workflow that needs to change.
Bring a recent enquiry, the route it took through the business and the tools that carried the information. Include the report leadership relies on and a handover that required manual intervention. Those examples reveal the records, responsibilities and exceptions the new system needs.
We inspect the source data and integration access, identify the internal product owner and agree a first complete release. The quote includes acceptance criteria, the delivery plan, migration coverage, responsibilities and the chosen ownership model. Builds start from £50,000; the final price reflects the agreed scope.
Before committing, compare a configured platform against the same workflow and a realistic operating-cost period. Custom software should earn its investment through a concrete business case, not simply a preference for a new interface.
Launch & continuity
An operating system the team can keep using.
Migration is rehearsed before cutover. The team tests the agreed scenarios with representative records and the actual roles. We reconcile important data, resolve blocking issues and establish who can make the launch decision.
Handover includes the agreed code and access, deployment documentation, training and support responsibilities. Hosting, third-party services and AI usage are recorded separately from the build investment. The company knows how to export its data and how another team could operate the system.
Ongoing maintenance and new product development are agreed separately. The same discipline that shapes the first release should guide what gets improved next.
Common questions
Before you build.
Clear scope. Clear responsibilities.
A better decision for the business.
Do you build custom CRMs for London businesses?
Yes. Wall & Fifth is a London-based product design and software studio. We agree the CRM scope, delivery format, stakeholder meetings and responsibilities with each client. Engagements start from £50,000.
Can we meet or run a discovery workshop?
Meeting and workshop arrangements are agreed for the project. The proposal identifies the format, people involved and any location or travel requirements; an on-site schedule is not implied by the build price.
Can we use a custom CRM across international teams?
That can be scoped, including team access, data relationships, timezone behaviour, integrations and relevant hosting requirements. The proposal defines the operation rather than assuming every international scenario is included.
What do you need to scope the project?
The key workflows, user roles, current CRM and connected tools, a sample of the source data and the person responsible internally. Real enquiry and handover examples help us define a useful first release.
