Management software for accounting firms
Everything your accounting firm uses every day, in one place.
Mail, tasks, calendar, CRM, invoicing and electronic signature, all connected and hosted on your own server — not someone else's cloud.
Nine fewer tabs open
A normal mail client, but one that categorizes on its own and helps you draft the reply.
Tasks and notes
The day's tasks organized by client, with a history of everything already done.
Calendar
Deadlines, appointments and timed tasks — without three different calendars open at once.
CRM
Clients and opportunities in the same place. No extra tab, no extra login.
Invoicing
“Invoice this client for this amount” and that's it — straight from the assistant itself.
Signatures
Real electronic signature, ready to send in a couple of clicks.
Drive
Documents editable right in the browser, nothing to install.
Tickets
One place to note what's broken or missing, with Kanban-style tracking.
AI assistant
Ask for what you need in one sentence and it does it: create a task, find an email, move a ticket.
Time tracking
Tamper-evident time records with cryptographic hash-chaining, ready for upcoming regulation.
Tax calendar
Quarterly/annual tax form deadlines generated and tracked per client, automatically.
It doesn't replace what already works for you. It brings it together.
You already know most of these tools separately: a CRM, an invoicing app, a place to sign documents. The problem was never the tool itself — it's logging into ten different sites, with ten different passwords, to do an afternoon's work.
Guilda Work doesn't reinvent CRM, invoicing or electronic signature from scratch — it connects the best of what already exists behind a single login, and adds an assistant that knows its way around every module when you ask it to.
And since it runs on your own server, what happens to your clients' data is up to you, not a privacy policy someone else can change next month.
What people usually ask
Is it secure?
As secure as the server it lives on: regular backups and active protection against brute-force attempts or known exploits. It's not magic, it's serious maintenance.
Can I take my data with me if I leave?
Yes. Notes and tasks export to JSON or CSV whenever you want, no permission needed.
Is there a mobile app?
Yes — there's a native iOS app (Android on the way), with the same tools and the same AI assistant as the web. Plus a token-based REST API if you want to connect your own.
Does it work with Claude or another AI?
Yes — the whole system speaks MCP, so you can connect it to whatever AI client you already use, without depending on the built-in assistant.
Does time tracking meet the regulation?
Yes. Insert-only time records with hash-chaining: any direct alteration in the database is mathematically detectable, not just “trusted”. Optional geolocation, exportable in a format ready for a future labour inspection.
Does it track my clients' tax deadlines?
Yes, if you run an accounting firm: Spanish tax forms (303, 390, 130, 111, 115, 200) generated automatically per client, with reminders before each deadline and, if you want, recurring generation every quarter.
