How to Build a Client Portal on Bubble.io: The Complete Guide
Client portals are one of the most frequently requested Bubble.io builds: a branded, secure space where an agency or service business shares deliverables, tracks project status, collects approvals, and communicates with clients. The data model, the core features, and the specific Bubble.io workflows that make a client portal work.
The Business Case
A client portal built on Bubble.io for an agency or service business serves three simultaneous business functions: it reduces the operational overhead of managing client communication (fewer emails, fewer update calls, fewer approval chases); it differentiates the agency’s service quality by providing a professional, branded digital experience that most competitors do not offer; and it creates a foundation for productising the agency’s service (the portal becomes the product). Client portals are particularly well-suited to Bubble.io because the core requirements — user authentication, multi-tenant data isolation, file sharing, status tracking, and approval workflows — are all natively supported by Bubble.io’s platform without requiring external services or complex integrations. SA has built multiple client portal products for agency clients, and the typical build time from Discovery Sprint to launch-ready portal is 2-3 weeks.
What to Build in the First Version
Feature 1: Branded client login and account management
Each client logs in with their own credentials and sees only their own data — no client can see another client’s projects, deliverables, or communications. The portal carries the agency’s branding (logo, colours, typography) on the login page and throughout the authenticated experience. SA builds client portals with the agency’s brand as a first-class design requirement, not an afterthought.
Feature 2: Project and deliverable tracking
The portal displays the client’s active projects with current status (In Progress, Under Review, Completed), the deliverables associated with each project, and the expected and actual completion dates. The project tracking view should give the client a clear, current picture of where their work stands without requiring them to email the agency for an update.
Feature 3: File sharing and deliverable download
The portal allows the agency to upload deliverable files (design assets, reports, documents, videos) that the client can view and download directly from the portal. File upload in Bubble.io uses the platform’s built-in file storage (or AWS S3 for large files) and the download link is generated dynamically for each file. SA builds file access controls that ensure clients can only access files associated with their own projects.
Feature 4: Approval and feedback workflows
The portal includes an approval mechanism: the client can view a deliverable and mark it as Approved or request revisions with a text comment. The agency is notified (via email or in-app notification) when a client has reviewed and either approved or requested changes on a deliverable. This replaces the back-and-forth approval email thread with a structured, trackable process that both parties can reference.
Feature 5: Messaging and communication log
An in-portal messaging interface that creates a single, searchable record of all client communication related to a project. The messaging interface should replace (or supplement) email for project-related communication, keeping all context in one place. SA builds messaging with email notification triggers: when the agency sends a message in the portal, the client receives an email notification with the message content and a link to the portal to reply.

How SA’s Discovery Sprint defines the specific workflows and data requirements of a client portal build before any development begins.
How to Structure the Bubble.io Database
| Data Type | Key Fields | Relationships | Purpose |
|---|---|---|---|
| Agency | Name, logo, brand colours, domain | Has many Clients, Projects | The top-level tenant; represents the agency using the portal |
| Client | Company name, contact name, email, login credentials | Belongs to Agency; has many Projects | Each client company; isolated from other clients |
| Project | Title, status, start date, deadline, description | Belongs to Client; has many Deliverables, Messages | The unit of work the agency is delivering for the client |
| Deliverable | Title, file URL, status (Pending Review / Approved / Revision Requested), feedback text | Belongs to Project | A specific output the agency has produced and the client must review |
| Message | Content, sender (Agency or Client), timestamp, read status | Belongs to Project | A single message in the project communication thread |
| Notification | Type, recipient (Agency or Client user), related record, read status | Belongs to Agency or Client user | Triggers email notifications and in-portal notification badges |
Q: Should I build a client portal as a standalone product or as part of my agency’s existing tools?
SA’s recommendation: build it as a standalone product from the start, even if the first version only serves your own agency’s clients. A standalone product has its own URL, its own brand, and its own data isolation — which is essential for multi-tenant security and which also creates the foundation for selling the portal as a product to other agencies in your vertical if the market opportunity emerges.
Q: How do I handle agencies that want to white-label the portal for their own clients?
Bubble.io’s multi-tenant architecture supports white-labelling: each Agency record in the database stores the brand assets (logo, colour scheme, domain), and the portal’s UI is dynamically styled based on the current user’s Agency record. An agency can therefore have the portal served on their own custom domain with their own branding, while the underlying platform is your product. SA builds white-label capability into client portals when the product is intended for multiple agency customers rather than a single agency’s own use.
Q: What is the typical cost to build a client portal on Bubble.io?
A basic client portal with the five features described in this post — branded login, project tracking, file sharing, approval workflows, and messaging — typically costs $8,000-15,000 with SA, depending on the complexity of the approval workflow and the number of notification types required. A more sophisticated portal with additional features (automated project status updates, invoice tracking, time logging, integrations with project management tools) ranges from $15,000-30,000. All SA builds begin with a $345 Discovery Sprint that produces a fixed build quote and a full feature specification.
