Licornne: the tool that's genuinely changing how we respond to our clients

Also available in French.

A tool built for finance professionals — not for tech teams

Please note: this article relates exclusively to accounting firms and professionals operating under French law.

In accounting firms, time is the scarcest resource. Every minute spent tracking down a regulatory answer, verifying a tax text or cross-referencing information is a minute taken away from the client.

That's precisely the observation that led us to adopt Licornne — a platform of specialised AI agents, designed specifically for accounting firms and finance professionals.

And to be straightforward about it: it's a game changer.

What Licornne actually is

Licornne is not a general-purpose AI assistant. It's a platform built on a simple principle: 1 AI agent = 1 professional expertise.

Each agent is trained on a specific scope:

  • Statutory auditing — analysis, legal obligations, reports
  • Tax control — doctrine, legislation, case law
  • Electronic invoicing — reform, formats, approved platforms
  • Business creation — legal structures, tax regimes, formalities
  • Property management — accounting, service charges, general meetings

This isn't an enhanced search engine. It's a virtual collaborator that knows its subject, knows where to look, and delivers a structured, reliable answer — in seconds.

What it changes for our teams at Trevys

Before Licornne, answering a client's specific question — on an electronic invoicing use case, on a particular tax regime, on a specific accounting obligation — could easily take several tens of minutes of documentary research.

With Licornne, our teams now have access in real time to:

  • A sourced answer, grounded in official texts and administrative doctrine
  • Greater precision: the agents are specialised, not generalist
  • Faster responses: the answer arrives before the call ends
  • More time freed up for advisory work — where the firm's real value lies

The platform integrates into daily workflows as a central hub: clients, documents, production, management and specialised AI agents, all in one place, connected to the firm's production tools.

The conviction behind this tool — and behind our choice

At Trevys, we have long held this view: technology must serve people, not the other way around.

Licornne embodies exactly that conviction. The tool doesn't replace the accountant's judgement — it liberates it. It takes care of the research, the verification, the formatting. The firm retains what matters most: reading the situation, managing the client relationship, delivering the strategic recommendation.

And that is precisely what we want to offer our clients: faster, more precise answers, delivered by teams who have more time to think.

A tool choice, a commitment to quality

Equipping our teams with Licornne is an investment in service quality. Not a technology gimmick, not a show of modernity — a concrete decision, in service of our clients.

Because a good answer given quickly is often the difference between a decision made in time and an opportunity missed.
