The problem

Every month, the same lost hours and the same fear of getting it wrong

Hand-made invoices, receipts nobody books, doubts about the tax office and tools that charge for every person you invite.

Invoices by hand

Templates, numbering and PDFs you send one by one.

Receipts in a shoebox

Tickets you type in (or forget) at the end of the quarter.

Is this compliant?

VERI*FACTU, time tracking, tax forms… and nobody warns you if something is missing.

Paying per user

Inviting your partner or your accountant costs money in other tools.

With Zynvio

Everything flows in, everything complies

Invoices, expenses, payroll and banks share the same data, every record meets the rules and your whole team gets in without paying extra. Free to start.

What you stop doing

Three things you forget about from today

Not a feature list: three chores that disappear from your week.

Forget typing

Scan a receipt and it is already booked. Your Shopify, Stripe or Amazon sales invoice themselves. Your bank reconciles without opening a spreadsheet.

  • OCR for expenses and received invoices
  • Recurring invoices and automatic collection
  • Bank reconciliation (PSD2)
Forget typing

Forget compliance

We take care of it. Every invoice leaves with its VERI*FACTU record, every clock-in is stored as the law requires and forms 303, 349, 111 and 190 fill themselves with your data.

  • Chained records sent to the AEAT
  • Legal, immutable time tracking
  • Tax forms ready to file
Forget compliance

Forget closing the month by hand

Automatic journal entries from every invoice, expense and payslip. Your accountant logs in with their own access and has everything up to date, without asking you by email.

  • Automatic Spanish GAAP (PGC) accounting
  • Own access for your accountant
  • Step-by-step assisted closing

Artificial intelligence

Your accounting, with AI. Connected to your favourite AI tools.

Zynvio suggests the ledger account for every invoice and expense. And through its MCP server, Claude, ChatGPT or Cursor answer with your real data: overdue invoices, quarterly VAT, margin per client.

AI accounting

Upload the invoice. The AI proposes account, VAT and withholding. You approve.

It learns from your corrections: more accurate every month.

FAQ

What people ask before creating their account

What freelancers and SMEs ask most before creating an account.

Is it really free forever?+

Yes. The Free plan never expires and asks for no card. It includes VERI*FACTU-compliant invoicing, expenses and clients within the limits shown on the plan card. You pay only if you need more volume or advanced modules, and you can cancel anytime.

Do you charge per user?+

No. Zynvio never charges for an additional user. Every paid plan includes unlimited users with roles and permissions per module; the Free plan includes the users shown on its card. Your accountant logs in with their own access.

Am I VERI*FACTU compliant with Zynvio?+

Yes. Every invoice generates a record with a chained hash and QR code as required by Spanish Royal Decree 1007/2023, and Zynvio submits it to the Spanish tax agency (AEAT). Our VERI*FACTU responsible declaration is published on the site.

What is the MCP connection and what can I do with it?+

MCP (Model Context Protocol) is an open standard that lets assistants such as Claude, ChatGPT or Cursor read your Zynvio data and, if you allow it, act on it: ask for overdue invoices, work out the quarter's VAT or prepare payment reminders. You control which permissions you grant and can revoke them at any time.

Can I bring my data from another program?+

Yes. Import clients, products, invoices and expenses from Excel or CSV, and connect Shopify, WooCommerce, Amazon, Stripe or PayPal so sales flow in by themselves.

Where is my data stored?+

On servers inside the European Union, encrypted in transit and at rest, with each company's data isolated and in compliance with the GDPR and Spanish data-protection law (LOPDGDD).

Start free now. No card, no lock-in, no per-user fees.
