Client Portal Development

We build secure portals where your customers sign in to see their projects, documents, requests and invoices, connected to the systems your team already uses to run the work.

01Our Approach

A portal earns its place when customers stop emailing to ask where things stand, because the answer is already on their screen.

02Overview

One signed-in place for every customer account

  • 01Role-based access
  • 02Document exchange
  • 03Request tracking

A client portal gives each customer an account where they can follow work in progress, exchange files, approve steps, raise requests and review invoices. We build the web application, the permissions model behind it and the connections to your CRM, project, finance and storage tools, so the portal shows live information instead of copies someone has to update.

It fits companies that serve many accounts through email threads, shared folders and status calls. Off-the-shelf portals work when your process is standard. A custom portal becomes worthwhile when your service has its own stages, documents and approvals, or when the portal is part of what customers pay for. We start with the few journeys that remove the most back-and-forth.

03What We Do

Capabilities, End to End

01
Accounts and permissions

Organizations, users, roles and invitations are modeled so each person sees only the projects, documents and actions that belong to their company and their job.

02
Document exchange

Customers upload and download files in a structured place with versions, required documents, expiry dates and an audit trail of who opened what and when.

03
Status and timelines

Each project or order shows its stage, next step, owner and history, drawn from your operational systems so nobody has to write a separate update.

04
Requests and approvals

Customers raise requests, answer questions and approve quotes or deliverables inside the portal, with notifications, due dates and a record of every decision.

05
Billing and statements

Invoices, payment status, statements and receipts appear in the account, with online payment through a provider such as Stripe where your process allows it.

06
Staff workspace

Your team gets an internal view to manage accounts, publish updates, respond to requests and see which customers are waiting on you.

06How It Runs

From Kickoff to Launch

01
Journey mapping
02
Permissions and prototype
03
Build and connect
04
Pilot and rollout
01
Journey mapping

We list the questions customers ask most, follow one account from signing to delivery, and choose the first journeys the portal should handle, such as status, documents and approvals.

02
Permissions and prototype

The data model and the roles matrix are written down, then a clickable prototype is tested with a few staff members and, where possible, a friendly customer.

03
Build and connect

We build the portal, connect it to your CRM, storage and finance tools, and test with real accounts in a staging environment, including the cases where data is missing or late.

04
Pilot and rollout

A small group of customers is invited first. Their questions shape the final wording and notifications, then remaining accounts are onboarded in batches with your team trained to support them.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Customers keep asking where their work stands

Account managers spend their days answering status emails, resending documents and chasing approvals. Information lives in inboxes and shared folders, and each customer sees a different version of it. You want one secure place that reflects your systems and reduces that traffic.

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Book a call

Buy when your service follows a common pattern and a product covers it without workarounds. Build when the portal must reflect stages, documents or rules that are specific to your business, when it has to draw on several internal systems, or when it carries your brand as part of the service. We will tell you honestly if a product is the better fit.

Access rules are enforced on the server for every request, not only hidden in the interface. Each record belongs to an organization, each user belongs to one or more organizations with a role, and automated tests try to read data across accounts. We also log access, support single sign-on and two-factor authentication, and review permissions with you before launch.

Yes, that is usually where the value comes from. We connect through the APIs of your CRM, project management, accounting, storage and e-signature tools, or through a database or file exchange when no API exists. For each connection we agree which system owns the data, how often it syncs and what the portal shows when a source is unavailable.

They use it when it answers their questions faster than email. That is why we begin with the journeys they ask about most, keep sign-in simple, send notifications that link straight to the relevant page and make the portal work well on a phone. A pilot with a few accounts shows what to adjust before everyone is invited.

You receive the complete source code, the database schema, the infrastructure configuration, documentation and access to every repository and environment. The portal runs in cloud accounts under your control. Your own developers or another partner can maintain it, and we remain available for further work if you want us to continue.
