TL;DR

A modern accounting onboarding workflow runs on a secure portal: templated request lists, structured intake forms, secure collection, and automated follow-up. It replaces email chasing with a checklist that completes itself. This guide shows how in six steps, with Alkmist as one EU-hosted, ISO 27001 option.

Why onboarding needs a workflow

An accounting client onboarding workflow collects intake forms and documents through a secure portal as tracked requests, chased automatically, validated on arrival, and logged.

Onboarding is where accounting firms lose partner hours to email and PDFs. A secure portal turns it into a tracked workflow that collects and chases itself.

Done well, onboarding documents arrive in order, securely, with a trail, without loosening compliance.

How to build the workflow, step by step

Six steps from email onboarding to an automated workflow.

  1. Template the onboarding request list

    Turn your standard onboarding into a reusable list of tracked requests with owners and due dates.

  2. Collect through a secure portal

    Replace email attachments with controlled uploads clients respond to in one place.

  3. Structure the intake forms

    Capture the information you need as structured forms alongside document requests.

  4. Automate follow-up

    Let reminders chase outstanding items and stop once received.

  5. Secure and screen every file

    Ensure encryption in transit and at rest, with files screened on arrival.

  6. Track onboarding to done

    Work from one dashboard of in, pending, and blocked, with a full trail.
