The best client portal software for small law firms in 2025 is Clio Manage for firms wanting full practice management, MyCase for cheaper bundled software, a standalone portal tool for firms that already have practice management, and a custom build for any firm with 5 or more attorneys. Custom portals start at $10,000 fixed and pay back within 18 to 24 months by eliminating $79 to $149 per user per month in SaaS fees.

We are biased. We build [custom client portals](/law-firm-client-portal) for law firms for a living. We will still tell you when a $79 a month tool is the right answer.

## The four real options

Most small firms end up choosing between four categories.

1. **Practice management with built-in portal:** Clio, MyCase, PracticePanther, Smokeball
2. **Generic document portal:** Microsoft SharePoint, Google Workspace, Box
3. **Standalone client portal tool:** Clinked, MyOpenDoor, LawWare
4. **Custom-built portal:** built specifically for your firm

We will go through each and then give clear recommendations.

## Option 1: Practice management with built-in portal

This is the default choice for most firms. You buy practice management software and the client portal comes bundled. The big four for small firms are Clio, MyCase, PracticePanther, and Smokeball.

**What you get:** Matter management, time tracking, invoicing, trust accounting, calendar, document storage, and a basic client portal. The portal lets clients log in to see invoices, upload documents, and message you.

**Pricing in 2025:**
- Clio Manage: $79 to $139 per user per month
- MyCase: $59 to $109 per user per month
- PracticePanther: $59 to $99 per user per month
- Smokeball: $79 to $159 per user per month

**Where it wins:** You get a full practice management system. If you do not have one yet, this is the easiest way to get a portal as part of a bigger upgrade. Clio in particular has the deepest integration ecosystem.

**Where it falls short:** The portal is almost always the weakest part of the product. It is a "good enough" feature, not a core focus. Customization is limited to your firm logo and a few field labels. You cannot change the workflow.

**Best for:** Firms that need a full practice management upgrade and are happy with a basic portal as a bonus feature.

## Option 2: Generic document portal

Microsoft SharePoint, Google Workspace, and Box are document sharing tools that some firms use as a poor-man's client portal.

**What you get:** Folder-based document sharing with per-client permissions. Audit trails, version control, and integration with your existing Microsoft or Google environment.

**Pricing in 2025:**
- SharePoint (with Microsoft 365 Business Premium): $22 per user per month
- Google Workspace Business Plus: $18 per user per month
- Box Business: $20 per user per month

**Where it wins:** Cheap. You probably already have it. IT security teams already approved it.

**Where it falls short:** Clients hate it. SharePoint in particular has a brutal client login experience. Folder navigation is not a workflow. There are no automated reminders. No matter dashboard. No invoice display. You are using a tool that was never designed for client-facing work as if it were one.

**Best for:** Firms that need internal document collaboration. Not client portals. Skip this category for client-facing use.

## Option 3: Standalone client portal tools

These are tools that just do the portal piece. They do not try to replace your practice management software.

**What you get:** A polished client login experience focused on document exchange, messaging, and approvals. They integrate with your existing tools rather than replacing them.

**Pricing in 2025:** $30 to $80 per user per month, with some pricing per client instead of per staff.

**Where it wins:** Better client experience than the bundled portals in practice management tools. Less expensive than full practice management.

**Where it falls short:** You have two systems. Client info has to stay in sync between the portal and your practice management tool. Workflows that span both are awkward.

**Best for:** Firms that love their existing practice management software but hate its built-in portal.

## Option 4: Custom-built portal

A portal built specifically for your firm, on top of modern web infrastructure, designed around your workflow.

**What you get:** Exactly the portal your firm needs. No features you do not use, no missing features you do need. Your branding, your terminology, your matter types, your reporting.

**Pricing in 2025:** $10,000 to $30,000 one-time for a focused portal. Hosting costs $50 to $200 per month depending on usage. We broke this down in detail in our [client portal cost guide](/blog/how-much-does-a-client-portal-cost-for-a-law-firm).

**Where it wins:** You own the software. Total cost over 5 years is dramatically lower for firms with more than 5 users. The portal works the way your firm works, not the other way around. You can add features as your firm grows without per-user fees.

**Where it falls short:** Upfront cost is higher than a monthly SaaS. You need a vendor you trust to actually deliver. Not every developer can ship a real portal in 3 weeks.

**Best for:** Firms with 5+ attorneys that plan to be in business for at least 3 years and want to control their own software.

## Side-by-side comparison

Here is a 10-attorney boutique firm with 5 support staff over 5 years.

| Option | 5-year total | You own it? | Workflow fit |
|---|---|---|---|
| Clio at $89 per user per month | $80,100 | No | Generic |
| MyCase at $79 per user per month | $71,100 | No | Generic |
| SharePoint at $22 per user per month | $19,800 | Subscription | Poor for clients |
| Standalone portal at $50 per user per month | $45,000 | No | Better than bundled |
| Custom build at $15,000 + $150 per month hosting | $24,000 | Yes | Built for you |

The custom build wins on total cost for any firm with 5+ users that plans to stay in business.

## Why custom wins for firms under 20 attorneys

Three reasons.

**You are too small to bend your workflow to fit a tool.** Big firms have IT teams that can change processes to match software. Small firms cannot afford that overhead. The tool needs to match how you work.

**Per-user pricing punishes you when you grow.** Hire two paralegals and your software bill jumps. Custom pricing is fixed once.

**Vendor lock-in is real.** Migrating off Clio or MyCase after 5 years of data is painful. Custom builds are yours. You can host them, modify them, or hand them to a new developer.

If you want a deeper read on when custom makes sense, our [for-business overview](/for-business) walks through the typical scope and timeline.

## How to actually decide

Ask three questions.

**1. How many attorneys and staff will use this in 3 years?**

Under 5: probably go with an off-the-shelf practice management tool. Above 5: custom usually wins on total cost of ownership.

**2. Do you have a workflow that is unusual?**

If your firm has a specific intake process, a custom billing structure, or a niche practice area like immigration or estate planning where standard tools do not fit, custom is worth the upfront cost.

**3. How important is the client experience?**

If client retention and referrals depend on a smooth digital experience, the bundled portals in practice management tools are usually not enough. A custom portal or a dedicated standalone tool is worth it.
