Assembly Alternative

A client portal built for onboarding, not everything

Assembly is a polished client portal — with e-signatures, payments, and automations. But onboarding is split across separate apps: forms in one, contracts in another, payments in a third. And its forms do not auto-save. Portico runs the whole intake as one guided, auto-saving sequence — forms, signatures, and payments in a single flow.

Why teams leave Assembly

Onboarding scattered across separate apps

Forms live in one app, contracts in another, payments in a third. Assembly has all three — but the client moves between them instead of flowing through one sequence. Portico runs forms, signatures, and payments as a single guided intake.

Single-scroll forms with no auto-save

All fields on one page — no progress bar, no step navigation. If a client closes the browser mid-form, the work can be lost. Portico auto-saves every field, so clients resume exactly where they left off.

9 field types and limited form logic

Short answer, long answer, file upload, and six more — no signature or payment fields, and no conditional branching inside forms today. Portico has 18+ field types, including inline signatures and payments, plus logic that adapts the form to each client.

Branding you do not fully control until Advanced

Assembly's 2.0 update applies your logo, font, and 3 brand colors across the login screen, emails, and invoices. But removing the "Powered by Assembly" badge entirely requires the Advanced plan at $399/month. Portico includes badge removal at $39/month.

Assembly is a polished client portal. Portico is purpose-built for onboarding.

Dashboard

Assembly

Assembly dashboard showing a 4-step setup checklist (25% completed), an analytics graph with no data, and 'Recently visited' links — a generic portal dashboard, not onboarding-focused

Portico

Portico dashboard showing active onboardings with step-by-step progress, recent activity timeline, and client status at a glance

Forms

Assembly

Assembly forms list showing a single 'Example Intake Form' in a sparse table with response counts — no templates, no conditional logic, no multi-step support

Portico

Portico template gallery with pre-built onboarding templates for different industries — conditional logic, multi-step forms, and e-signatures built in

Onboarding automation

Assembly

Assembly's automation builder opens to an empty state with 'Automate your firm' and a single 'Create a workflow' button — capable, but you build onboarding workflows from scratch

Portico

Portico onboarding detail showing automated step tracking, completion status, and item-specific reminders — automation built into every onboarding

Onboarding that works. Not a portal with forms bolted on.

Every feature in Portico exists to get clients onboarded faster. Nothing extra, nothing missing.
  • Forms, signatures, and payments in one flow

    Clients fill in fields, sign contracts, and pay deposits as steps in a single guided sequence — not three separate apps. Nothing to hand off, nothing to switch between.

  • Multi-step forms with auto-save

    Clients see step 2 of 5, not an endless scroll. Auto-save on every field means they can close the browser and resume exactly where they left off — work is never lost.

  • Per-field review built for onboarding

    Per-onboarding message threads, per-field comments, and approve, reject, or request-changes on individual answers. Review tooling shaped around intake — not a generic chat bolted onto a portal.

  • 18+ field types with conditional logic

    Text, file uploads, signatures, payments, dates, dropdowns, multi-select, ratings — plus branching logic that shows different fields based on previous answers.

  • Full branding — not just the sidebar

    Logo, colors, custom domain, branded emails with your sender name. Remove the "Powered by" badge on the Starter tier. Your brand on every surface clients see.
