InvoiceXpress brings AI to Portuguese invoicing

Rui Alves, CEO of InvoiceXpress, has launched an AI-powered invoicing integration built on Anthropic's Claude platform, allowing Portuguese businesses to issue invoices, record receipts, query overdue documents, analyse billing data, and update client records through natural language commands, with no programming required.

The integration uses Model Context Protocol (MCP), an architecture that acts as a secure bridge between AI platforms and external software. Until now, connecting an AI assistant to invoicing software required custom development work. InvoiceXpress's MCP eliminates that step entirely, making Claude a direct operator of the invoicing layer.

For existing InvoiceXpress customers, access is included in current accounts at no additional cost.

InvoiceXpress is a Lisbon-based cloud invoicing platform founded in 2009, serving 12,000 customers and issuing over 1.5 million documents monthly. It holds certification number 192 from the Portuguese Tax Authority (Autoridade Tributária), a mandatory compliance credential for invoicing software operating in Portugal. That certification is the structural barrier any AI-native competitor would need years to replicate: every action executed through the MCP integration runs on top of a certified, always-compliant tax layer, updated automatically as Portuguese law changes.

The closest global comparison is the Intuit, Anthropic partnership announced in February 2026, which brought MCP integrations to QuickBooks, TurboTax, Credit Karma, and Mailchimp for Claude Enterprise users. Intuit operates at global scale but carries no Portuguese tax-compliance layer. That gap is precisely where InvoiceXpress holds its ground.

InvoiceXpress was acquired by Norwegian software group Visma in February 2024, following Visma's 2023 acquisition of Moloni, InvoiceXpress's closest Portuguese competitor. Both certified SME invoicing platforms now sit inside the same parent group. The MCP launch gives Visma a concrete product differentiator for the InvoiceXpress brand before Moloni matches the feature, a window that is narrow given the two products serve the same 12,000-strong SME base.

The timing lands against a backdrop of accelerating AI adoption in European business. Eurostat data show 20% of EU companies with ten or more employees already use AI in operations, up from 13.5% the prior year. In Portugal, 11.5% of companies in that size band report active AI use, representing a 34% increase year on year.

"The next step is to allow AI not just to answer questions, but to execute real business tasks." — Rui Alves, CEO.

The launch hands Visma a localised MCP integration built on certified infrastructure before any global invoicing platform can replicate the Portuguese compliance stack. How quickly Moloni follows will determine whether the advantage holds inside Visma's own portfolio.
