What is a custom client portal?

A secure website or app built for your organization where clients, partners or staff log in to see their own data and complete tasks, connected to your internal systems.

How is this different from client portal software?

Portal software gives you a standard set of features. A custom portal follows your workflows, connects to your ERP and CRM, and enforces your own permission rules.

How long does it take to build a client portal?

Most first releases take about 8 to 14 weeks after a short assessment and design phase.

How much does a custom portal cost?

It depends on the number of user types, integrations and workflows. Most first releases take about 8 to 14 weeks, and we scope it with you before we start.

Can the portal connect to our ERP and CRM?

Yes. Integration with your existing systems is the main reason to build a custom portal.

Is the portal secure?

Yes. We use role-based access, sign-in through your existing identity provider and audit logging, so each user only sees what their role allows.

Can we start small and add features later?

Yes, and we recommend it. The first release covers the workflows that matter most, and new features are added in small releases once people are using the portal.

Do you build with low-code tools like Power Apps or custom code?

Both. Low-code platforms such as Power Apps suit internal portals on Microsoft 365. Custom code, for example in .NET or Node.js, suits client-facing portals that need full control over design, performance and integrations.

Who owns the portal once it is built?

You do. We document the solution and train your team, and we can stay on for support and new features if you want.

Custom Client Portal Development

Alphabyte builds custom client and customer portals for organizations that have outgrown off-the-shelf tools. Each portal is a secure, single place where clients, partners or staff see their data, submit requests and get work done.

Portals connect directly to your ERP, CRM and reporting, and often become the custom ERP layer teams rely on every day.

What We Do

Customer portal development built around how your business works.

Portal software works well for file sharing and simple requests. When clients need live data from your systems, role-based permissions or your own approval and quoting rules, a custom portal fits better. We design and build it, then support it as you grow.

Typical examples are bid and proposal tracking for construction firms, month-end hubs for finance teams, and secure reporting portals for funders or boards. Each one replaces spreadsheets and email chains with one place to work.

We pick the stack that fits your environment, including Microsoft Power Apps, .NET, Node.js and Azure, with Power BI for embedded reporting.

Client Portals

Self-service access to orders, projects, documents and invoices.

Partner Portals

ERP-Style Apps

System Integrations

How Can Alphabyte Help Me?

Assessment
Over 1 to 2 weeks we review your systems, workflows and challenges to find where a portal adds the most value. We look for the steps where people re-key data or chase information by email.
Scope of Work
We agree on features, integrations, users and milestones, so development stays focused and predictable. The first release covers the workflows that matter most.
Business & Workflow Discovery
We map how each user type works today and how the portal should support them, then design screens around those steps. Users review the designs before we build.
Architecture & Integration Design
We design a portal architecture that connects cleanly to your existing systems and data sources. Access rules are designed up front, so each user only sees what their role allows.
Build, Launch & Support
We build in releases over about 8 to 14 weeks, test with real users, launch, and keep improving the portal. New features are added in small releases as your needs change.

Client Portals Success Stories

Construction

Companies like Modern Niagara send out hundreds of proposals and bids each year to prospective customers. This process is often managed manually across multiple spreadsheets, making it difficult to achieve full oversight of the sales funnel. This often translates to a lack of visibility and missed opportunities.

Financial Management

The PowerApps application serves as a one-stop hub for both Financial Analysts and Managers to manage all month-end financial operations. Reporting has also been embedded directly into the application so that users are not required to navigate between multiple environments.

Your Custom App Development Partner

Alphabyte builds client portals that go beyond simple applications. Our team combines application development, data engineering, reporting and cloud architecture, and we have built portals for construction, professional services, finance and accounting, and the public sector.

You own the portal and its data. We document what we build and train your team, and we can stay on for support and new features after launch.

If a portal product covers most of what you need, buy it. If your workflows, data or permissions are what make you different, a custom portal usually costs less over time. See our build vs buy guide, custom software development and Power Apps.
