The story

This is an Edinburgh-based accountancy practice with 2,500 clients and a team of 9. The directors were spending a significant portion of every week on email. Routine replies, client updates, chasing, and follow-ups. The kind of work that has to happen but doesn't grow the business.

The practice operates in a highly regulated environment. Any system handling client communications needed to meet strict data protection requirements, ensure client confidentiality, and operate within professional conduct standards. There was no room for shortcuts.

We started by analysing over 14,000 sent emails to understand how each team member actually communicates. Their tone, their language, their way of handling different types of enquiry. From that, we built individual voice profiles so the system drafts replies that sound like each person, not like a template.

The system classifies every incoming email, drafts a reply, escalates anything urgent, and filters noise. Sensitive information like National Insurance numbers, UTR references, and bank details are automatically stripped before processing. All data stays within the practice's own Microsoft 365 environment. Every draft is reviewed by a team member before it's sent.

Within 8 weeks, the system had processed over 4,800 emails. 87% of drafts were sent with only minor edits. Response times dropped to under 3 minutes. The directors estimate they've gained roughly 100 hours a month back, time they're now spending with clients and staff instead of in their inbox.

Privacy and compliance

In a regulated profession, data protection isn't a feature. It's the foundation. Every part of this system was designed with compliance first.

Automatic PII redaction

National Insurance numbers, UTR references, and bank details are stripped automatically before any processing takes place.

Data stays in-house

Everything operates within the practice's own Microsoft 365 tenant. Client data never leaves their infrastructure.

GDPR compliant by design

The system was built from the ground up to meet data protection requirements, not retrofitted.

Human in the loop

Every draft is reviewed by a team member before it reaches a client. Nothing goes out without approval.
