Most firms send three or four emails during onboarding: a welcome, a request for documents, a confirmation that the work is done, and an invoice. That is not an onboarding programme - it is a transaction. The firms with the best retention numbers run a structured nine-email sequence across the first 60 days, each with a specific job to do. Here is the sequence, with the purpose and the practical contents of each message.
1. The same-day welcome from the named partner
Sent within four hours of engagement letter signature. From the named partner, not the firm address. Confirms the engagement, names the team, sets the kick-off call date, and links to the portal credentials. The tone is human and brief - under 150 words. This single email materially shapes the client's impression of the firm.
2. The portal walkthrough
Sent on day two. Short video link (under three minutes) walking through how to log in, where to find documents, how to send a secure message, and where to see job status. Clients who watch a walkthrough video are roughly twice as likely to become active portal users in the first 30 days as those who do not.
3. The structured document request
Sent on day three with a clear list, owner, deadline and upload link. Not a vague "send us what you have." Categorised by priority - what is needed for the first month of work versus what can wait until quarter end.
- Identification documents for AML - passport, proof of address, dated within three months
- Prior accountant handover pack - last filed accounts, tax computations, working papers
- Bookkeeping access - Xero, QuickBooks, Sage or Zoho Books read access
- Bank statements covering the last 12 months
- Companies House authentication code if applicable
4. The kick-off call confirmation
Sent the day before the kick-off call with the agenda, dial-in link, and a one-paragraph summary of what will be discussed. Includes a soft prompt to bring any questions in writing. This dramatically improves the productivity of the call itself.
5. The post-kick-off summary and action list
Sent within 24 hours of the kick-off call. Recaps decisions made, lists action items with owners and dates, and confirms the next scheduled contact. Treated as a mini-engagement letter for ongoing work. This is the email that signals to the client that your firm is organised and professional.
6. The first quick-win delivery
Sent between days 10 and 14. Delivers something useful - a Companies House deadline calendar, a VAT scheme sense-check, a basic cashflow snapshot - that was not strictly in the engagement. Frames it as "while we were getting your records set up, we noticed this and thought it would be useful." Cost: 30 minutes. Impact: lasting.
7. The team introduction
Sent around day 21. Introduces the wider team beyond the named partner and manager - bookkeeper, AML officer, tax specialist. Brief bios, photos, direct portal-message links. Reduces single-point-of-failure risk on the client relationship and signals firm depth.
8. The first deliverable hand-off
Sent on or before day 30, accompanying the first piece of substantive work. Explains what was done, what the numbers mean in plain English, what the client should do next, and what to expect in the following month. The plain-English explanation matters - accountants routinely under-rate how much value a well-written summary adds.
9. The 30-day check-in survey
Sent on day 30 or 31. Three questions only: how clear has onboarding been, how responsive have we been, what should we change. Sent through the portal, not as a generic survey link. Responses go to the named partner, and any score below 9 triggers a personal follow-up within five working days.
Tying the sequence together
The sequence above looks like nine emails. Operationally, it is a workflow with nine milestones, nine owners and nine deadlines. Coded into a practice-management system, it runs itself: the practice-management layer triggers each message, flags missed deadlines, and surfaces clients whose onboarding has stalled before it becomes a churn risk. Accupe handles this as part of the same workflow that tracks jobs, compliance and capacity - and every message goes through the branded portal rather than personal email, so the audit trail is intact and the client experience is consistent.
Closing
Nine emails is not a lot. It is roughly two per week for the first month. But run consistently for every new client, this sequence is the difference between a chaotic first impression and a structured, professional onboarding experience that earns the right to a five-year client relationship. Build it once, run it forever.
