What is the best client portal software in 2026?

Assembly is the new name of Copilot, which itself started as Portal in 2020. The rebrand happened in 2025, and copilot.app now redirects to assembly.com. If a review talks about Copilot, it's the same product, sometimes with stale pricing. Today it's the most polished portal on the client side: your client logs in and sees files, messages, invoices, forms and contracts to sign, in an interface that feels like an app rather than a dashboard.

The free plan is enough to run a real pilot: 1 internal user, 5 active contacts and 3 apps. Starter is $29 a month billed yearly or $49 month to month, for 1 user and 50 contacts. Professional moves to 3 users and 500 contacts, adds your own domain and removes the Assembly badge. Advanced goes to 5 users and unlimited contacts.

The app system is the real strength. You add what you need to the portal (files, payments, contracts, forms, a help center), and each extra app beyond your plan's quota costs $5 a month. Assembly claims GDPR, SOC 2 and HIPAA compliance, which matters if you handle health or financial records.

The catch: on Starter, your client sees the Assembly badge and a URL that isn't yours. Custom domains start at Professional. Reviewers also flag the cost climbing fast and the lack of time tracking or a serious CRM. Assembly is a portal, not a full business management suite.

Tip: an "active contact" is a client you've invited. Archive clients from finished projects to stay under Starter's 50-contact cap instead of upgrading for old files.

Softr doesn't sell you a ready-made portal. It gives you the building blocks to make your own without code. You connect your data (Airtable, Google Sheets, Softr's own database and other sources), drop in blocks (lists, detail pages, forms, tables) and decide what each client sees after login. A law firm can show case status, an agency can show deliverables by project, a training company can show each learner's documents.

The free plan lets you build and publish a first portal. Basic is $49 a month billed yearly and adds your custom domain. Professional ($139) and Business ($269) are for heavier portals with more users and advanced features.

It has the best ease-of-use score in this ranking, 4.7 out of 5 in our full Softr review. The client portal templates give you a working base in minutes, and the AI co-builder drafts a first version from a plain description.

The catch: you build it, so you maintain it. There's no ready-made invoicing, e-signature or client messaging like Assembly or HoneyBook. You wire those in yourself (Stripe, a signature tool, Zapier or Make), and every extra piece is one more thing that can break.

Tip: build the portal for three clients on the free plan with your real data. You'll know quickly whether Basic's user limits work for you before paying.

HoneyBook is the name most American service businesses hear first, and for good reason. It runs the whole client journey: inquiry, proposal, contract, invoice, payment, with a client portal on every plan where clients find all of it in one place.

Pricing is simple: Starter $29, Essentials $49 and Premium $109 a month, billed yearly. Payments are where the real cost hides. Cards run 2.9% + 25¢ per transaction and ACH 1.5%. On large invoices paid by card, the fees can exceed several months of subscription.

The portal itself is clean and client-friendly, and the proposal-to-payment flow is where HoneyBook beats tools that bolt a portal onto a project manager. It's built for one-to-one service work, not for sharing a large document library with a firm's clients.

The catch: HoneyBook is only available in the US, Canada, the UK and Australia. If you work with clients elsewhere, they can pay you, but you can't run your business on it from another country. Payment fees also make it pricier than it looks if most of your revenue comes in by card.

Tip: push clients toward ACH on large invoices. At 1.5% instead of 2.9% + 25¢, the difference covers your subscription. Our page on switching from HoneyBook covers the alternatives if you outgrow it.

Plutio bundles project management, proposals, contracts, invoicing and a client portal in one subscription. Your client logs in, checks progress, signs, pays and messages you without switching tools. E-signature is included on every plan.

What sets it apart: Plutio takes no cut of your payments. You connect Stripe, PayPal or Square and only their processing fees apply. Next to a tool that adds its own fee, that adds up over a year of invoices.

Watch the Core cap: $19 a month or $190 a year, but only 9 active clients and one user. Past that, Pro is $49 a month or $490 a year, with 30 contributors and unlimited clients. White label is a $9-a-month add-on on Core and Pro, included in Max ($199).

The catch: the interface looks dated next to Assembly, and reviewers report bugs, no public status page and automations that sometimes need a third-party tool. On the plus side, Plutio's support gets a lot of praise for how fast it answers.

Tip: the 7-day trial is limited to 3 clients. Invite three real clients instead of test accounts and you'll know within a week whether they actually use the portal.

Dubsado's pitch is automation. You build workflows that send the questionnaire, then the contract, then the invoice, then the reminder, each one triggered by the client's last action. The client portal sits on both plans and gathers everything the client has received.

Pricing is yearly and flat: Starter at $335 and Premier at $525, both with unlimited clients and projects. That makes it one of the cheapest options once you pass a few dozen clients. The 21-day trial is the longest in this ranking and needs no card.

Reviewers are clear about the cost in time. Setup estimates run from 15 to 40 hours, and the learning curve is steep. Automation is the reason people stay, but the portal is described as functional rather than polished. Some users also report the scheduler booking over busy slots.

The catch: Starter allows only 1 active form, which limits the automations you can build before upgrading to Premier.

Tip: map your client journey on paper before you open Dubsado. Users who start building without a plan are the ones who report losing weeks.

SuiteDash makes a bet nobody else in this ranking makes: unlimited clients and unlimited users on every plan. START is $19 a month or $180 a year, THRIVE $49 ($480 a year), PINNACLE $99 ($960 a year). What changes between plans is mostly storage (100 GB, 500 GB, 2 TB) and advanced features.

In one tool you get the client portal, a CRM, projects, contracts with e-signature, invoicing, payments and subscriptions, and the vendor promotes deep white labeling from START. There's also a one-time lifetime license, from $2,240 to $6,840 depending on the tier.

The downside is well known. Reviewers say it's not plug-and-play, mention 20+ hours in the SuiteDash Academy, a busy interface, limited native integrations and a restricted API. Users outside the US also report no multi-currency support and incomplete translations.

The catch: the custom domain. Third-party pages say it's available from START, but the official help center lists it under PINNACLE. Check during the trial before you pick a plan.

Tip: the 14-day trial runs on PINNACLE, the full plan. Write down which features you actually use in those two weeks. Most small businesses only need START or THRIVE.
