Problems We Solve

  • Your team manages leads in spreadsheets — data is lost, duplicated, and invisible.
  • Off-the-shelf CRM (HubSpot, Salesforce) does not fit your UK business workflow.
  • Your client portal is a shared Google Drive — unprofessional and insecure.
  • Sales, invoicing, and project data live in three separate tools that do not connect.
  • Your CRM has no UK GDPR compliance — storing personal data without proper controls.

Frequently Asked Questions

A small UK custom CRM (lead pipeline, basic client portal, invoicing) starts from £8,000. A medium CRM with workflow automation and integrations costs £15,000–£40,000. A large enterprise CRM starts from £40,000. All GBP with milestone contracts.
Off-the-shelf CRMs charge per seat indefinitely and rarely fit complex UK business workflows without expensive customisation. A custom CRM is built exactly for your process, owned permanently, and scales without monthly licence fees. For most UK businesses with 5+ users, a custom CRM pays for itself within 2–3 years.
Yes. Every ARS Developer CRM implements UK GDPR architecture: consent-based data collection, AES-256 encryption, role-based access per least privilege, right to erasure, data retention policy enforcement, and audit trail logging. ICO-ready from day one.

How We Work With UK Businesses

1 Book a Free Consultation

Tell us what the CRM has to do. We work with businesses across the UK, reply within one business day in UK hours, and will say up front if this is not the right approach.

2 Receive a Scoped Proposal

A written proposal covering pipeline stages, user roles and reporting, milestones and GBP pricing. Scope is fixed before work starts — no open-ended retainer.

3 Milestone-Based Delivery

The CRM arrives in reviewable stages. You approve each milestone before the next begins, so there is no large unreviewed handover at the end.

4 Launch and Post-Launch Support

We run the launch, monitor it afterwards, and hand over documentation another developer could pick up. Monthly maintenance is available, not compulsory.
