Client Portal Development Cost
Cost ranges for custom client portal development, including login, documents, requests, billing, and CRM connections.
A client portal is a branded, authenticated place where customers get work done without emailing for status, files, or invoices. Starter portals on this site start from $4,000–$5,000, business portals from $7,500, and advanced portals from $15,000.
The price moves with roles, document handling, messaging, payments, and whether the portal has to stay in sync with a CRM or other internal system.
Starter versus business scope
A starter portal typically covers secure login, a customer dashboard, and a small set of records — projects, orders, or documents. That is enough when the goal is to stop sending the same attachments repeatedly.
A business portal adds requests, notifications, richer account information, and clearer role-based access for clients who have several people in the account.
When cost steps up
Invoice and payment flows, audit logs, CRM write-back, and custom approval workflows add design and testing. They are worth it when the portal is part of delivery, not a brochure with a login screen.
If you already have a CRM, connecting the portal is usually cheaper long-term than maintaining two lists of the same customers.
Ongoing cost
Portals hold customer data. Hosting, backups, monitoring, and security updates should be planned from day one. Maintenance plans exist so that work is not an emergency invoice every time a library needs patching.
