Larenio

Every client and every deadline, in one place.

Larenio is a client-management tool for UK accountancy firms and the small businesses they work with. It keeps customer records and recurring obligations — statutory deadlines, renewals, follow-ups — off the spreadsheet and somewhere a whole team can rely on.

Larenio is currently invite-only. Access is provided to firms we onboard directly.

What Larenio does

  • A shared record of every client or customer, with custom fields and an activity log.
  • Tracks recurring deadlines and reminds the right person before they fall due.
  • Optional UK-accountancy features: statutory deadline dates and Companies House lookup.
  • Optionally connects to Google Calendar or Microsoft 365 so deadlines appear in your calendar.
  • Sends reminder and client emails on the firm's behalf.

How your data is handled

Data is stored securely in the United Kingdom / EU (AWS, London region) with sensitive fields encrypted. When you choose to connect a Google or Microsoft calendar, Larenio uses that access only to create and update calendar entries for your own deadlines — never to read unrelated data, and never for advertising. Full detail is in our privacy policy.
