A client portal your customers use instead of phoning you

Backendz builds branded client portals and booking systems where customers book appointments, track jobs and orders, sign documents, pay invoices and download reports, all connected live to your own systems.

Or see how we engage first — four shapes, no sales call required.

  • Customer portals
  • Online booking
  • Availability & calendars
  • Appointment reminders
  • Job & order tracking
  • Document sharing
  • E-signatures
  • Online payments
  • Invoices & statements
  • Support requests
  • Reports & certificates
  • Multi-user accounts
  • Branded white-label
  • Single sign-on
  • Notifications
  • Mobile-friendly

We let your customers help themselves

  • No more phone calls asking where a job or order is

  • Stop emailing reports and certificates one by one

  • Forget booking tools that don't know your real availability

  • Done with chasing signatures on contracts and quotes

  • Skip paying for a portal that shows customers a fraction of what they need

  • Say bye to invoices paid weeks late because paying is awkward

Why build custom client portals & booking with us?

We've built customer portals

Including a customer portal for a UK water treatment business, connected to service and compliance records.

Live data, not copies

The portal reads from your real systems, so customers see what your team sees.

Your brand, your domain

White-labelled to look like part of your business.

Secure by design

Each customer sees only their own data, with full access logs.

The people who have to live with what we build

Operations directors, CTOs and plant managers — the ones still using the system a year after the invoice cleared.

We wanted answers our team could check against the original document. Having the relevant clause beside the response makes the assistant useful when reviewing policies and contracts.
Emma CollinsHead of Business Operations at Clearbrook Advisory
We needed scheduling, availability and shift changes in one place. Backendz shaped the system around the way our operations team works and stayed involved after launch to help us refine it.
James CarterOperations Director at Northbridge Facilities
Our rental journey had to work for both vehicle owners and travellers. Backendz brought listings, availability and bookings together into a platform that feels straightforward to use.

We wanted a practical way to review PPE and safety-zone events using our existing cameras. The team focused on the situations our site managers need to investigate and made the footage easier to review.
Daniel BrooksSite Operations Manager at Oakmere Construction
A single headcount does not tell us where congestion is developing. The zone-based view gives our team a clearer picture of how people are moving and where attention may be needed.
Olivia ReedVenue Operations Director at Cedarhall Events
The priority was a counting workflow our warehouse team could use during a normal shift. Backendz connected image-based counts with the records we already use and made discrepancies easier to review.
Michael TurnerWarehouse Manager at Harbourline Logistics
Tender preparation involves gathering evidence and getting the right people to review each section. Backendz brought those steps into one workspace, with drafts our team can check and approve.
William ParkerBid Manager at Westhaven Technical Services
Our information was spread across several operational systems. Backendz designed a clearer way to ask questions, inspect the supporting evidence and keep approval with our team before an action is taken.
Charlotte HayesChief Operating Officer at Elmbridge Services Group
Our estimating process needed to reflect how we actually price work. Backendz took time to understand the inputs and rules, then built a quoting journey our team could review and refine.
Thomas MitchellManaging Director at Ridgewell Roofing & Cladding
The reconciliation workflow gives our finance team one place to review mismatches and supporting records. We can trace an exception back to its source and decide what needs attention.
Henry WilsonFinance Director at Ashford Distribution
The team took time to understand how our staff work between appointments. The resulting system brings scheduling and client information together without making the day more complicated.
Amelia FosterHead of Operations at Meadowcrest Care
We had outgrown the spreadsheets that held our pricing rules. Backendz helped turn that knowledge into a quoting tool we can maintain and explain to new colleagues.
George EvansManaging Director at Stonefield Fabrication
We could review working features throughout the build and give specific feedback. That made it easier to keep the product focused on the people using it.
Isabel MorganProduct Director at Brightpath Learning
Connecting our sales and inventory systems was the priority. The integration gives our team a clearer view of updates and a practical way to investigate records that need review.
Jack HarrisonTechnology Manager at Westbrook Retail
Our field team needed access to job details away from the office. The mobile workflow keeps the relevant information close at hand and gives the office a clearer view of progress.
Grace PhillipsOperations Lead at Alderway Field Services
The cloud work started with understanding our existing systems and dependencies. The team documented the setup and gave us a clearer basis for monitoring and ongoing maintenance.
Oscar BennettIT Director at Brookvale Manufacturing

FAQ

The things people ask before they commit.

Still have questions?

Ask it on the call. We would rather answer an awkward question early than discover it in month three.

Book a call
What is a client portal?

A client portal is a secure, branded website where a business's customers log in to see their own information and do things themselves: book appointments, track jobs or orders, download documents, sign contracts, pay invoices and raise requests.

Why build a custom client portal?

Off-the-shelf portals often show only part of what customers need and don't connect to your own systems. A custom portal reads live from your job, ERP or CRM data, matches your services exactly and has no per-client fees.

Can customers book online through the portal?

Yes. Booking can check real availability of staff, engineers, rooms or equipment, take deposits or payments, and send reminders and rescheduling links automatically.

Is a client portal secure?

Yes, when built properly. Each customer can only see their own data, users sign in securely, every access is logged and data is encrypted in transit and at rest.

Can the portal take payments?

Yes. Customers can pay invoices or booking deposits online by card or bank payment, with payments recorded automatically in your systems.

How long does it take to build a client portal?

A focused portal typically takes 8 to 12 weeks, depending on features and the number of systems it connects to.
