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.

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.
A focused UK CRM (lead pipeline, client portal, basic invoicing) takes 6–10 weeks. A medium CRM with automation and integrations takes 12–20 weeks. All timelines confirmed with milestones before development starts.
