Customer Portal Development Services
Self-service web portals for your own customers: account access, orders and invoices, documents, support requests and status tracking, connected to the CRM, ERP and accounting systems you already run. Fixed-price builds from $15,000, with source code and IP transferred to you on final payment.
What is customer portal development?
Customer portal development is building a secure, logged-in website where your customers handle their own business with you: checking order status, downloading invoices, paying balances, sharing documents and opening support requests. A B2B customer portal does the same for business accounts with several users each, replacing the email threads and phone calls your staff answer today.
Client portal, customer portal and B2B portal name the same thing in different industries. What they share is that the people logging in work outside your company, so the portal has to be easy to use without training and strict about who sees what.
This page covers portals for your customers. For internal tools, dashboards and the wider range of business software we build, see our custom application development services.
Custom web portal vs. a CRM portal add-on: when to build
Choose a CRM portal add-on when customers only need records that already live in that CRM, shown in the layout the vendor provides. Build a custom web portal when it must pull from several systems, follow a workflow the add-on cannot express, carry your brand throughout, or avoid per-user fees that grow with your customer base.
The data lives in more than one system
Orders sit in the ERP, invoices in accounting, and tickets in a help desk. A portal add-on to one of them shows customers only part of the picture.
The workflow is yours, not the vendor's
Quotes, approvals, reorders or onboarding steps that do not fit the fixed screens an add-on provides.
Licensing grows with every customer
Some add-ons and builders price by portal user, so the bill rises as more of your customers log in.
The portal is part of what you sell
When the customer experience is a reason buyers choose you, a vendor template that looks like everyone else's works against you.
Portal add-on vs. no-code portal builder vs. custom portal
| CRM portal add-on | No-code portal builder | Custom web portal | |
|---|---|---|---|
| Best fit | Customers viewing records already in one CRM or help desk | Simple portals over one spreadsheet or database | Portals spanning several systems or a workflow of your own |
| Branding | Vendor templates with your logo and colors | Theme-level control inside the builder's components | Your design on your domain, screen by screen |
| Integrations | Strong with its own platform, limited beyond it | Prebuilt connectors; custom logic is harder | Built against your CRM, ERP, accounting and payment APIs |
| Data ownership | Data stays on the vendor's platform | Data and logic live on the builder's platform | Source code and IP transfer to you on final payment |
| Cost shape | Recurring license, often priced per user | Monthly subscription, often tiered by users or records | Fixed-price build from $15,000; retainers for ongoing work from $1,750/month |
What a customer portal includes
A customer portal includes secure login with roles, account and order history, invoices and online payments, document sharing, support requests, notifications, and integrations with the CRM, ERP and accounting systems that hold the data. A sensible first release starts with the features that remove the most staff work, and adds the rest in later phases.
Login and roles
Customers sign in with email and password, a magic link, or their company's single sign-on. Business accounts get an account admin who invites colleagues and decides what each one can see.
Account and order history
Open orders, shipment or project status, and past purchases in one place, so customers stop calling to ask.
Invoices and payments
Customers view and download invoices, check balances, and pay online through a processor such as Stripe.
Document sharing
Contracts, reports and customer uploads, organized by account, with permissions on each file.
Support requests
Customers open and track requests, attach files, and read replies without an email thread. Requests can route into the help desk your team already uses.
Notifications
Email or in-portal alerts when an order ships, an invoice comes due, a document is ready, or a request changes status.
Integrations with CRM, ERP and accounting
The portal reads from and writes to your systems of record instead of becoming one more copy of the data to keep in sync.
Integrations are often the largest part of a portal build. When your systems do not expose the endpoints a portal needs, our API development services build that layer first, so the portal and any future app can share it.
Our web portal development services: how we build a portal
Code and Trust builds a web portal in phases: Discovery & Scoping, Design & Build, Launch & Handoff, Ongoing Partnership. Discovery maps your customer types, what each needs to do, and which systems hold the data, and the scope and price are agreed in writing before the build. Prototype, staging, and deployment milestones are agreed in the written scope.
Discovery & Scoping
Understand the workflow, agree on the deliverables, and set the scope, price, and delivery milestones before the build.
For a portal, that means each customer type, what they need to do without calling you, and every system involved.
Design & Build
Design, develop, and test the agreed scope. Review working software and give feedback at the milestones in the delivery plan.
Login, roles and the account structure come first, because every other screen depends on who is looking at it.
Launch & Handoff
Deploy the software, prepare the team handoff, and provide the agreed post-launch support. Source code and IP transfer on final payment.
Ongoing Partnership
Most large builds are fixed-price, with a monthly retainer after launch. Ongoing development, maintenance, and support are scoped separately.
Most custom software projects take 8–16 weeks from kickoff to production, depending on scope and integrations. Prototype, staging, and deployment milestones are agreed in the written scope. We build on React and TypeScript for the front end, Node.js or Python for back-end services, and PostgreSQL as the primary database, the same stack behind our web application development work.
Security and access control
Security in a customer portal starts with access control: each customer sees only their own account, and each user only what their role allows. Code and Trust builds role-based access control in from day one, not after launch, and scopes single sign-on, multi-factor authentication and audit logging during discovery.
Account isolation
Requests are checked against the signed-in customer's account, so one customer's orders, invoices and files stay out of another customer's view.
Roles inside a customer account
An account admin, a buyer and an accounts-payable contact need different screens. Roles decide who can order, who can pay, and who can only view.
Roles for your own staff
Support reads accounts, finance adjusts invoices, and few people can change permissions.
Authentication options
Sign-in can run through an established identity provider such as Auth0. Single sign-on through Okta or Azure AD, multi-factor authentication, and audit logging each add scope, and are agreed in writing.
If the portal will hold regulated data, name the regulation in the first conversation, so the requirements it brings are scoped in discovery.
What drives web portal development cost
Web portal development cost is driven by how many systems the portal integrates with, how many customer and staff roles it supports, authentication and compliance requirements, payments and document handling, and how clearly the scope is defined before the build. Code and Trust offers fixed-price builds from $15,000, with the price agreed in writing.
Integrations
Each system the portal reads from or writes to adds scoping, error handling, and ongoing maintenance. This usually moves the price more than any other factor.
Roles and account structure
One customer type with one role is simple. Business accounts with admins, buyers and approvers, plus staff roles behind them, multiply the screens and permission rules.
Authentication and compliance
Single sign-on, multi-factor authentication, audit logging, and regulated data each add a defined block of scope.
Payments and documents
Online payments and sensitive file storage add work beyond displaying records.
How well the scope is defined
Clear requirements shorten discovery and reduce mid-build changes.
Most large builds are fixed-price, with a monthly retainer after launch. Monthly retainers are available from $1,750/month for ongoing work. Post-launch support and maintenance are scoped per engagement. For the full breakdown, read how much custom software development costs, or get an estimate for your customer portal.
