HomeArtificial intelligence
Applied artificial intelligenceAI that’s already at work, starting with our own business
We use artificial intelligence every day at Tisa and build it into our clients’ ERP, email and applications. Agents that read, record and write, always with a person who approves what matters.
It’s not a chatbot: it’s a digital employee inside Business Central
Tisa Nexus monitors the mailbox, understands what comes in and turns it into real transactions in the ERP.
A supplier invoice that arrives by email is ready as a purchase invoice in Business Central in about 2 minutes, with duplicate checks.
In production since April 2026.
Handles email
Sorts each message, reads the attachments (PDF, Word, Excel and images) and proposes or carries out the right action.
Where you already work
Web chat, email, Microsoft Teams and Telegram.
Learns from every interaction
A memory of the company, its processes and each user, consolidated every night.
Works to a schedule
Scheduled tasks, follow-up of pending items and escalation to a person when something is out of the ordinary.
Under control
Approvals, autonomy limits, an audit trail of every step, its reasoning live and the cost of every task in plain view.
Tisa Nexus Light
Supplier invoices that arrive by email, read and organised automatically
For companies without an ERP, or that would rather not touch it: Nexus Light reads the mailbox, recognises invoices and extracts their data with a confidence score for each field. Anything it is unsure about is left for a person to review.
- Supplier, CIF (Spanish tax ID), number, dates, tax base, VAT, IRPF (income tax withholding) and total, from the PDF, a scanned photo or the email itself
- Suppliers grouped by CIF and alias, and rules it learns from corrections
- Dashboard with indicators, export to Excel and an organised copy for the accountant
- Installed on the client’s server, with the cost of every step in plain view
In production since August 2026.

AI in local government
The more paperwork, the more it saves
We bring AI to the municipal applications we already develop, always as an aid to council officers: it proposes and explains, and the decision still rests with a person.
Traffic fines
It reads the number plate in the speed camera photo and checks it against the offence report; it sorts appeals and drafts the reply. If in doubt, the case goes to the exceptions queue.
Tax roll campaigns
It reviews the result of each simulation and flags data conflicts and recommendations before the bills are generated. It only reads and drafts: it does not execute anything.
Claude rollouts
We bring Claude to your company, just as we have brought it to ours
We work with Anthropic’s Claude as a tool for the whole team, as the basis for procedures that run the same way every time and as the engine for custom agents.
Claude for your team
We install it, configure it with your company’s knowledge and train management and staff on real use cases. We have already rolled it out at an advisory firm, with a kick-off session with its management and use cases of its own.
Automated procedures
We turn repetitive tasks into procedures that Claude carries out the same way every time: quotes in the ERP, email drafts with the right signature and thread, Business Central queries, and reports and documents on the company template. That’s how we work at Tisa.
Custom agents
Agents built with the Claude API and Agent SDK, connected to your ERP, email, Teams or applications, with restricted permissions, approvals and a log of everything they do.
AI and data consultancy
For those who want to start sensibly: we analyse your processes and your data, choose the first use case and get it up and running.
- Identifying the processes and data where AI adds the most value
- Comparison of tools to suit your situation and your budget
- Data governance, management and quality (Spanish UNE 0077, 0078 and 0079 specifications)
- Development and launch of a measurable use case
- Team training in the strategic use of AI
- Review of risks, security and compliance with the EU AI Act
A person decides
Posting, paying or sending requires approval until you say otherwise.
Everything is traceable
What it read, what it proposed, who approved it and what it cost.
Your data stays yours
Business-grade AI services that do not train on your data, and minimum permissions in every system.
Start small
A measurable use case in weeks, then grow from what works.
Which task would you like to take off your plate?
Tell us about it. In one meeting we’ll tell you whether AI can do it today, how, and with what controls.
