A client portal integrated with your ERP turns your operational system into a client-facing trust asset. Instead of clients calling to find out where their job is at, they log in and see it. This guide covers what to build, when to build it, and how to connect it to your back-office.
Why this matters now
For service businesses with recurring clients — cleaning companies, maintenance contractors, facility managers — the biggest source of inbound calls and emails is status enquiries. "When is the next visit?", "Can I get a copy of the last invoice?", "What happened on the site visit Tuesday?". Every one of those calls costs 5–10 minutes of admin time. Multiply by 20 clients and 4 enquiries per month each, and that is 7–13 hours of admin every month — just answering questions that the portal would answer instantly.
Deep execution plan (30 days)
Phase 1: Define what clients need to see (Week 1)
- Survey your top 10 clients: what questions do they ask most frequently?
- Map the data that answers those questions to the records that already exist in your ERP
- Define the three core portal views: job history, current schedule, and invoices
- Decide on authentication: email/password login, or magic link by email
Phase 2: Build the portal core (Weeks 2–3)
- Build client-scoped data access: each login sees only their own records
- Build the three core views: upcoming jobs, completed jobs with reports, and invoice list with payment links
- Add a request form: clients can submit service requests that land in the back-office job queue
- Mobile-responsive design — most clients will access the portal from their phone
Phase 3: Connect to the ERP back-office (Week 3)
- Verify that a job marked complete in the back-office immediately appears as complete in the portal
- Test that a photo uploaded by a field staff member is visible in the portal within minutes
- Confirm that invoice status updates in Xero reflect in the portal (paid, outstanding, overdue)
- Test the request form: a submission in the portal appears as a new enquiry in the back-office
Phase 4: Roll out to key clients (Week 4)
- Onboard your top 5 recurring clients first — they will get the most value and give you the best feedback
- Send a brief email introducing the portal and what it contains
- Measure: inbound status enquiries per client in the 30 days before and after launch
What to include in the portal
Upcoming schedule: Next scheduled visits, with date, time window, and assigned staff.
Job history: Every completed visit with date, scope, completion notes, and attached photos.
Invoices: Full invoice history with status (outstanding, paid, overdue) and one-click payment links.
Documents: Completion reports, certificates, compliance documents — everything the client might need to find without calling.
Service request form: Submit a new job or enquiry directly from the portal. No email required.
Contact log: A record of every communication — so both parties have the same history.
Security considerations
Client portals handle sensitive business data. Build with these controls in place from the start:
- Individual login credentials per contact — never share logins across clients
- Role-based access: a facility manager at Client A cannot see Client B's records
- Audit log: every login and data access event is recorded
- Session timeout: portal sessions expire after a period of inactivity
Summary
A client portal is one of the highest-perceived-value additions to a service ERP. It costs relatively little to build once the back-office data exists — the portal is just a window into it. The return is lower inbound admin, higher client retention, and a material differentiator when competing for commercial contracts.
