Portals that give every user exactly what they need

We build customer and partner portals with role-based access, self-service tools, and workflow automation - so every stakeholder gets a tailored experience without custom builds per user type.

What's included

Everything you need, nothing you don't

We scope each engagement precisely so you get senior-level work on the capabilities that matter.

  • Role-based dashboards

    Customized home screens for customers, partners, and admins - each role sees only the data and actions relevant to them.

  • Document management

    Secure upload, versioning, and sharing with access controls - contracts, invoices, and reports in one place.

  • Workflow automation

    Approval chains, status tracking, and triggered notifications that replace email threads and manual follow-ups.

  • Self-service tools

    Account management, order tracking, and support requests - so users resolve issues without calling your team.

  • Audit trails

    Immutable logs of every action for compliance, dispute resolution, and operational transparency.

  • White-label support

    Custom branding, domains, and theming so partners can offer the portal under their own identity.


From requirements to a live portal

We map roles and workflows first, then build in sprints with stakeholder demos at every stage.

  • Week 1: Roles, workflows & access model

    We document user types, permissions, document flows, and integrations - with wireframes for each role's dashboard.

  • Weeks 2-10: Portal build & integrations

  • Launch: Security review & onboarding

    We run access audits, set up SSO, and provide admin training so your team can onboard users from day one.

Renting is local, so search had to understand a place and a date range as one question rather than two filters. Mirimera built the marketplace and the software our suppliers run on, and because it is one system underneath, nothing has ever had to be kept in sync.
