Gemini How It Works
Here is what actually happens: your AI agent reads LEAP Legal matters for the billing period , client name, matter type, time entries, and billing rates.
For each client, it checks the VAT situation. EU-based client with a valid VAT number? The agent validates it through VATNode , confirms the number is active, retrieves the company name and country, and determines whether the reverse-charge mechanism applies (B2B cross-border within the EU).
Client without a VAT number? The agent retrieves the standard VAT rate for the client's country , 21% for Netherlands, 19% for Germany, 23% for Portugal, 20% for France.
The billing summary in Google Sheets shows: net amount, applicable VAT rate, VAT amount, and gross total. A German client with a valid VAT number and a Portuguese matter: reverse charge, 0% VAT, note on invoice.
A Dutch individual client: 21% BTW applied. The math is handled. The compliance is built in.
Connector Orchestration: 3 Connectors, one intelligent agent
Connect LEAP Legal, VATNode and Google Sheets Connectors so your AI agent reads matter details and time entries from LEAP, validates the correct VAT rate for the client's EU jurisdiction through VATNode, and builds a tax-compliant billing summary in Google Sheets. European law firms handling cross-border matters , where VAT rates change by client country and service type , get invoices that are correct from the start. No manual rate lookups. No VAT errors on quarterly filings.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 5,800+ Connectors and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across all tools, in one conversation. That's what this connectivity layer was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across all platforms.
Contextual Reasoning
Each decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your Connectors once, and your agent handles the rest. Each time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius AI Connectors to handle these for you. You describe what you need. It does the rest.

Frequently Asked Questions About This Connector Orchestration
Which Connectors do I need for this workflow?
Three: LEAP Legal, VATNode and Google Sheets. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client that supports the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others. Connect the Connectors and use any prompt.
Does this handle the reverse-charge mechanism correctly?
The agent validates the VAT number, confirms the client's country, and determines whether cross-border B2B rules apply. If the client has a valid EU VAT number in a different member state, reverse charge applies at 0%. This is the standard EU rule , consult your tax advisor for specific situations.
What about UK clients after Brexit?
UK companies no longer have EU VAT numbers. The agent recognizes GB-prefix numbers as non-EU and marks the invoice as VAT-exempt. Your UK invoices follow your country's rules for non-EU service exports.
Is my financial data secure?
Connectors authenticate through API keys or OAuth. Your agent only accesses LEAP matters, VATNode validation results and Google Sheets you have granted access to. Vinkius does not store your data.
Can I use this for non-legal EU businesses?
The LEAP Legal MCP is specific to law firms. But the VATNode + Google Sheets combination works for any EU business that needs cross-border VAT compliance. Replace LEAP with your industry-specific MCP for a similar workflow.
