Tallio routes documents from software to licensed e-invoicing providers, handling invoices, receipts and credit notes. The provider stays the legal issuer.
What it is
Tallio: the homepage
Tallio is an API that connects software to licensed e-invoicing providers. Your software sends one document to Tallio, which routes it to the provider the business already uses. The provider signs the document, transmits it to the tax authority, and keeps the legal archive.
Tallio handles invoices, receipts and credit notes through one document model that works with every provider. Each document has one status at a time: pending, issued, rejected, failed or cancelled. The API returns the registration, including the MARK and QR code in Greece.
AI agents can preview, issue and look up documents through Tallio's MCP server. The Model Context Protocol lets an AI client call tools matching the API's operations, with the same validation, errors and access as any other client.
The sandbox is free. When you go live, you choose a monthly plan by the number of documents you issue: Launch at €49/month up to 1,000 documents, Pro at €199/month up to 10,000, Scale from €599/month up to 100,000, or Enterprise for volumes above 100,000.

Quick answers
Is Tallio an e-invoicing provider?
No. Tallio is the connector, never the provider of record. The licensed provider the business already uses is the legal issuer and keeps the legal archive. On the direct myDATA route, the business transmits under its own credentials and the tax authority keeps the record.
What counts as a document for billing?
Each document issued through a provider: an invoice, a receipt or a credit note. Documents sent to the sandbox are free.
Can I start before a provider is connected?
Yes. Start with a sandbox key. The sandbox stands in for the provider and tax authority, so you can send test documents and get the same responses and webhooks, and nothing reaches the tax authority.
Does the provider charge separately?
Yes. Your e-invoicing provider's own subscription is separate and paid to them. Tallio's price covers Tallio only.
Does Tallio keep copies of invoices?
Tallio keeps document metadata such as status and the MARK, but holds no fiscal archive. The provider keeps the legal record. For support, the full request and response are kept encrypted with personal data redacted, and deleted after 90 days.
