Custom apps · Client portal
Client portal development.
When customers keep emailing to ask where things stand, the fix is rarely another email. A client portal gives every customer a private, logged-in view of their own documents, status, and payments, and gives your team one organized place to answer them. We design and build portals that fit how your business actually works, working remotely from our Providence, RI studio for clients across the US and Canada.
Quick answer
A client portal is a secure, logged-in area of your website where each customer sees their own documents, status, messages, and invoices. GEO Marketing Group designs and builds custom portals starting around $8,000, typically $16,000, working remotely from Providence, RI for businesses across the US and Canada.
What it does
Client portal, in plain language.
A client portal is a secure, logged-in area of your website where customers see their own information: documents, status, messages, invoices, and next steps. It replaces long email threads and repeated phone calls with one place both sides can trust. You decide what each client can see and do.

What client portal builds include
Secure login with password reset, optional two-factor authentication, and per-client permissions
Document exchange with upload, download, version history, and an activity log
Status tracking so clients can see where their project, case, or order stands without calling
Secure messaging with email or text notifications when something needs their attention
Invoices and online payment through Stripe or the processor you already use
An admin side for your team with search, bulk actions, and exportable records
How we build it
The stack behind client portal builds.
We typically build a client portal as a Node application with an Astro or React front end, a Postgres database, encrypted files in private S3-compatible object storage with signed expiring links, session-based authentication, and Stripe for payments, deployed on managed hosting with automated backups.
