Can you invoice by talking to an AI in Spain? Yes, and it's completely legal: the law doesn't require any specific program to issue invoices — it requires the invoice to have sequential numbering, sender and recipient NIF, date, description and IVA breakdown. You type "invoice Company X €2,000 for consulting" and AI generates an invoice meeting all those requirements: calculates IVA (21%, 10% or 4% as applicable), applies IRPF withholding when relevant, creates the PDF with your NIF and sequential numbering, and emails it to your client. All in about 10 seconds.
Let's be honest, because you probably landed here searching for "WhatsApp invoicing": FacturaHub does not run on a WhatsApp bot. Tools that do exist (FactuPro and others), and we had that channel ourselves — we retired it. A bot inside a messaging chat is a cut-down AI: no long context, none of your tools, bound to the platform's rules. FacturaHub's bet is invoicing by talking to a real AI: connect your account to Claude via MCP and say "invoice the April sprint to Vertex" while you work, or open the dashboard and the AI builds the invoice just as fast. The result "WhatsApp invoicing" promised — one sentence, one invoice — but with a full AI behind it.
What about expense receipts? The other half of the chat's appeal was sending a receipt photo. That still exists, without a bot: upload the photo to the dashboard (from your phone, on the spot) and AI reads it with OCR — extracting amount, input IVA, vendor and category — and the expense is logged, counting toward your quarterly Modelo 303. You can also hand the receipt to Claude via MCP and let it log it.
What about Verifactu? The AEAT regulation (mandatory from January 2027 for companies and July 2027 for freelancers) requires invoicing software to generate chained-hash records and optionally send them to the AEAT in real time. FacturaHub has Verifactu built in and free, and when it becomes mandatory it activates without migrating data or switching tools. Invoicing by talking to AI and complying with Verifactu aren't opposites: the invoice is generated server-side with all controls; the conversation is just the door.
Getting started takes 2 minutes: sign up free at facturahub.com and you're invoicing from the dashboard. If you use Claude, connect the MCP server (guide at /es/spain/mcp-facturacion) and invoice conversationally without leaving your workflow. Dashboard and AI share the same data in real time — two doors, one system. For the full picture of what AI can do for your invoicing, see /es/spain/facturacion-con-ia.
"Invoice Acme €2,000 for consulting" — from the dashboard or by talking to Claude (MCP). IVA, IRPF, PDF and email, in seconds.
Sequential numbering, NIF, IVA and IRPF breakdown. The PDF complies with Spanish invoicing regulation.
Mandatory in 2027. Already available in FacturaHub for free and activates without migrating data.
Everything the AI does appears in the dashboard instantly: P&L reports, Modelo 303, clients, teams.
No. We had that channel and retired it: a bot in a chat is a cut-down AI. Today you invoice by talking to Claude (connected via MCP) or from the AI dashboard — the same result, with a full AI behind it.
Yes. The law regulates invoice content (sequential numbering, NIF, IVA), not the tool you create it with. FacturaHub generates invoices compliant with Spanish regulation, and is Verifactu-ready (2027).
Natural language: "invoice Acme €2,000 for March consulting" — in the dashboard or to Claude via MCP. AI identifies the client (or creates them), calculates IVA and IRPF, generates the PDF and sends it. If something is missing, it asks you.
Upload the receipt photo to the dashboard and AI reads it: amount, input IVA and category via OCR. The expense is logged and counts toward your quarterly Modelo 303. You can also hand it to Claude via MCP.
Nothing. Invoices, expenses, Modelo 303, Verifactu and watermark-free PDF are free and unlimited, no card. Each AI action uses 1 token: you get 10 free AI actions per month and, if you need more, one-off token packs (100 for €4.99, 500 for €19.99, 1,500 for €49.99) that never expire.
