Three weeks is a long time to start

A new client's first experience of working with a practice sets the tone for everything that follows. For this firm, that first experience involved back-and-forth email threads spanning two to three weeks: collecting identity documents, obtaining engagement letter signatures, and gathering the financial background needed to begin work.

The process was inconsistent because it depended on individual staff members managing it differently. Some were thorough and prompt. Others let things drift. New clients were left waiting, uncertain what was needed next and when work would begin. Documents occasionally went missing between inbox and filing system.

For a practice built on professional credibility, a chaotic onboarding experience was undermining the qualities that clients were engaging the firm for in the first place.

The automation

When a new client is added to the practice management system, the onboarding sequence begins automatically. The client receives a step-by-step pack covering each requirement in order: identity verification, engagement letter signature via e-sign, and a structured intake form covering their financial situation and immediate needs. Each step tracks completion. Incomplete steps trigger automated nudges at set intervals. Staff only receive a notification when an onboarding is fully complete and all documents are filed.

Every new client gets the same experience, regardless of which staff member initiated the relationship.

The results

  1. Average onboarding time dropped from two to three weeks to four to five days
  2. Consistent experience delivered for every new client, regardless of which staff member handles the account
  3. No documents lost or missing at the point of onboarding completion
  4. Staff time on onboarding coordination reduced significantly, with attention only required at genuine exceptions
