Overview

What this engagement is

Every hour your team spends answering "where are we with this?" is an hour a portal could have saved. Cyntra builds client portals that expose exactly the right slice of your internal systems — status, documents, invoices, approvals — with authorisation enforced server-side.

Business problems this solves

  • Clients emailing for status, documents and invoice copies
  • Sensitive files shared through consumer file-sharing links
  • Approvals collected over email with no audit trail
  • Invoice payment requiring manual bank instructions
  • No professional self-service experience for enterprise clients

What is included

Secure client authentication with invitation flow
Project/engagement status and milestone views
Document repository with permissioned sharing
Proposal and change-order approval workflow
Invoice viewing and online payment
Support ticket and message threads
Email notification system

Questions about this service

Can it connect to systems we already use?
Yes — the portal is typically a secure presentation layer over your existing project, finance and document systems, synced through APIs or scheduled jobs.

Cutting six days from every property closing

Regional real estate brokerage, 45 agents

Challenge

Portal leads landed in a shared inbox where average response time was over four hours — well past the point at which conversion collapses. Transaction documents lived across personal drives, commission statements were rebuilt manually each month, and disclosure trails were hard to reconstruct when disputed.

Recovering nine points of realisation for a consultancy

Management consultancy, 60 consultants

Challenge

Time was captured late — often reconstructed at week-end — which eroded realisation through forgotten work and unbillable write-offs. Engagement scope changes were agreed in email and frequently absorbed rather than billed. Invoicing took eight days of partner and finance effort each month.

Cutting variation disputes 70% for a commercial contractor

Commercial construction contractor

Challenge

Daily site reports were captured on paper and frequently lost. Variations were agreed verbally and disputed at claim time, with roughly $600,000 in annual variation value written off. Subcontractor insurance certificates expired unnoticed, and cost-to-complete was only visible after month-end.
