What do you need before you start?

• A clear idea of who will use the portal: clients, staff or both.
• The three to five things a client must be able to do.
• A list of the information you will store, such as clients, matters and documents.
• An understanding of who may see what.
• A decision about which platform to use.

Step 1: Define the goal and the audience

Write one sentence: “Clients of our firm will use this portal to ___ so that we no longer ___.” For example: upload documents and see progress, so that we no longer chase by email. This sentence keeps scope under control.

Step 2: List the core actions

Choose three to five. For a typical firm: log in, upload documents against a request list, see the status of their matter, send a message and view invoices. Everything else is a later version. See what to cut before you build.

Step 3: Choose your approach

Step 4: Design the data and roles

Decide the data types and how they connect. A simple example:

Getting this right early is the most important step. See database design mistakes.

Step 5: Build the core flows

1. Registration and login, including password reset.
2. The client dashboard showing their matters and what is outstanding.
3. Document upload and request checklist.
4. Messaging attached to each matter.
5. The staff view with workload and overdue items.
6. Email notifications for key events.

Step 6: Lock down access

Set privacy rules so each client can see only their own records, enforced in the data and not just hidden in the interface. This is the step most often missed. See our security guide.

Step 7: Test with two accounts

• Log in as two different clients and try to open each other’s records, including by changing IDs.
• Log in as staff and as admin and check each role.
• Test failures: wrong passwords, large files, empty fields.
• Check that emails arrive and links work.

Step 8: Pilot with a few clients

Invite three to five of your most cooperative clients. Watch where they hesitate and fix those points before wider rollout.

Step 9: Launch and guide clients

Send a short how-to, make the portal the preferred route and keep a human fallback for clients who need help.

Step 10: Improve with real use

Review what clients and staff actually use. Add features in stages, and keep a record of changes. See what maintenance involves.

How long does it take?

Planning and a focused first version typically take a few weeks for a professional build. Professional Bubble.io builds at Simple Automation Solutions typically launch in 2 to 6 weeks, depending on scope. DIY timelines vary with experience.

Do you really need no code at all?

“Without code” does not mean “without planning”. The platform removes the programming, not the need to decide scope, data structure and security. Many founders build a prototype themselves, then have an expert review it before real clients use it. See our Discovery Sprint for a $345, 24-hour plan.

Frequently asked questions

Can I build a client portal myself without coding?

Yes, for a simple prototype. For a portal that holds real client data, have an experienced person design the data model and privacy rules and test it before launch.

What is the best no-code platform for a client portal?

It depends on your needs. Bubble.io suits custom workflows and multiple roles. Lighter tools suit simpler portals. See our platform comparison for how to choose.

How much does it cost?

DIY costs your time plus platform fees. A professional Bubble.io build starts at $3,500, with the final price based on scope.

How do I keep client data secure?

Use data-level privacy rules, enforce roles, keep keys private, test with multiple accounts and follow data protection rules where you operate.

Should I start with a pilot?

Yes. A small pilot with a few clients reveals problems cheaply.
