Can you invoice via WhatsApp 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. With FacturaHub you type "invoice Company X €2,000 for consulting" in a WhatsApp chat 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, without opening your computer.
The important difference is between two kinds of "WhatsApp invoicing". Some programs use WhatsApp only to SEND an already-made invoice (you create it on their website with forms, then share it via chat). FacturaHub uses WhatsApp as the full management interface: create invoices, log expenses by sending a receipt photo (AI extracts amount, IVA and category via OCR), check who owes you, request an expense report or add a client — all conversationally. And when you want full control, the web dashboard has everything: clients, P&L reports, Modelo 303, teams. It's the ERP that fits in your WhatsApp.
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 — available on Growth plans and above — and when it becomes mandatory it activates without migrating data or switching tools. Invoicing via WhatsApp and complying with Verifactu aren't opposites: the invoice is generated server-side with all controls, WhatsApp is just the door.
Why not use the AEAT's free app? The Spanish Tax Agency released a free Verifactu invoicing app for low-volume freelancers. It issues the invoice and little else: it doesn't track your expenses, doesn't calculate your Modelo 303 by crossing output and input IVA, has no AI, doesn't work via WhatsApp and won't flag unpaid invoices. It's the digital equivalent of filling in the form by hand. FacturaHub does that and everything else — and its free plan (3 documents per month, no card) also costs zero.
Getting started takes 2 minutes: sign up free at facturahub.com, connect your WhatsApp number with a verification code, and send your first message. Your first invoice comes out of your first chat. If one day you prefer the computer, the dashboard has exactly the same data in real time — and from Claude (MCP) you can also invoice while you work. Three channels, one system.
Create invoices, log expenses with a photo, check reports and manage clients — all by chat. WhatsApp is the interface, not a notification channel.
Sequential numbering, NIF, IVA and IRPF breakdown. The PDF complies with Spanish invoicing regulation.
Mandatory in 2027. Already available in FacturaHub (Growth+) and activates without migrating data.
Everything you do via WhatsApp appears in the web dashboard instantly: P&L reports, Modelo 303, clients, teams.
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". AI identifies the client (or creates them), calculates IVA and IRPF, generates the PDF and sends it. If something is missing, it asks you.
Yes: send a receipt photo and AI extracts amount, input IVA and category via OCR. The expense is logged and counts toward your quarterly Modelo 303.
Nothing changes: WhatsApp, the web dashboard and Claude (MCP) share the same data in real time. Invoice by chat today and review reports in the dashboard tomorrow.
The free plan includes 3 documents per month with all features (WhatsApp, AI, Modelo 303, watermark-free PDF), no card. Paid plans range from €4.99 to €79 per month by volume.
