AI invoicing means you describe what happened and the software does the rest: type "invoice Acme €2,000 for the March website" — via WhatsApp, from Claude or in the dashboard — and AI identifies the client, calculates IVA at the right rate (21%, 10% or 4%), applies IRPF withholding if your activity carries it, generates the PDF with your NIF and sequential numbering, and emails it. It's not autocompleting a form faster: the form disappears. FacturaHub is AI-native — AI isn't an added feature, it's how you operate the whole system.
The second half of AI is expenses. Send a receipt photo (via WhatsApp or uploading to the dashboard) and AI-powered OCR extracts the amount, input IVA, vendor and category. No typing. Each expense automatically counts toward your quarterly Modelo 303: FacturaHub crosses output IVA (your invoices) with input IVA (your expenses) and generates the box-by-box breakdown ready for your accountant or the AEAT.
How to tell real AI from marketing: (1) can you create a complete invoice in natural language, or does the "assistant" only answer questions? (2) does the receipt photo become a logged expense with IVA broken down, or is it just stored as an attachment? (3) does the AI know your business — clients, prices, who owes you — or does every conversation start from zero? FacturaHub has Business Memory: the more you use it, the more context it has, answering things like "how much does Acme owe me?" with your real data.
For technical users there's a third door unique in the Spanish market: the MCP server. Connect FacturaHub to Claude Desktop or Claude Code and invoice without leaving your editor: "invoice the April sprint to Vertex". There's also a REST API and npm CLI. No traditional Spanish invoicing tool (Holded, Quipu, Billin) offers this today.
And compliance is non-negotiable: invoices meet Spanish regulation (sequential numbering, NIF, IVA/IRPF breakdown) and Verifactu is built in — available on Growth+ plans and ready for when it becomes mandatory (January 2027 companies, July 2027 freelancers). The free plan includes 3 documents per month with all the AI: no card, no lock-in, no crippled version.
Describe the work and the invoice exists: IVA, IRPF, PDF and email. Via WhatsApp, Claude or dashboard.
Receipt photo → amount, input IVA and category extracted. Counts toward Modelo 303 instantly.
AI learns your clients, prices and patterns. Ask it who owes you or how much IVA you owe.
For developers: REST API, npm CLI and MCP server for Claude. Invoice from your editor.
IVA rates (21%, 10%, 4%, exempt) are applied with tax rules, not AI improvisation. AI interprets your message; the tax calculation is deterministic. And you always see the invoice before it goes out.
A chatbot answers questions about the program. In FacturaHub, AI OPERATES the program: creates invoices, logs expenses, queries data. It's the interface, not a side helper.
No. Your data is used only to operate your account, travels encrypted and is hosted on EU servers with GDPR compliance.
Yes, fully: natural language, receipt OCR, Modelo 303 and all three channels. The free plan limit is volume (3 documents/month), not features.
