Quick answer
Emailing sensitive documents is insecure and increasingly unacceptable under GDPR. A client portal provides a secure, centralised, and trackable way to exchange files, protecting client information and keeping your practice compliant.
Why should you move away from email sharing?
Email is not secure, and you have no control once an attachment is sent.
When you send an attachment via email, you relinquish control. A secure portal means the client must log in, and you can track exactly when they have accessed it.
How to Share Documents Securely With Clients: step by step
- 1
Choose a secure portal
Select a reputable client portal for sharing sensitive documents.
- 2

- 3

Upload documents directly to the portal instead of emailing them.
- 5
Notify clients
Send a secure notification directing them to their portal account.

Why a single client record matters
When client details, deadlines, documents and conversations are spread across inboxes and spreadsheets, time goes on searching instead of on client work.
One version of the truth
Everyone sees the same services, contacts, deadlines and notes for each client.
Accurate deadlines
Companies House sync brings in company details and filing dates, reducing manual errors.
Better client service
A full timeline means anyone can answer a client question with the history in front of them.
Secure document sharing
A client portal is safer than sending financial documents as email attachments.
Practical tips from UK practice
- Import companies from Companies House rather than typing details by hand.
- Record every service a client takes, so recurring work is created automatically.
- Add a short note after every important client call.
- Ask clients to upload documents through the portal rather than by email.
