Delivery notes + AT

Creates the delivery note and reports it to the Tax Authority.

Not vaporware

Born inside a real company.
Processing real invoices, every day.

elorun wasn't built in a lab. It grew inside HIGIMAX, connected to a live Sage 50c — signed invoices, delivery notes reported to AT, real stock. Every capability was proven where it counts: in the operations of a company that invoices every day.

🏭

In production, not in slides

Real fiscal documents signed by the API, verified in the database.

🇵🇹

Portuguese compliance

ATCUD, RSA signature and delivery note reporting to AT — as the law requires.

Questions everyone asks

Does my data leave my server? +

No. Sage and the database stay exactly where they are — on your machine. elorun is only the secure bridge that exposes the API; data is never copied to our cloud.

Do I have to change or upgrade my Sage 50c? +

Nothing changes in your Sage. elorun runs alongside it, uses Sage's official API, and doesn't touch your configuration or your data.

What if my internet goes down? +

Your Sage keeps working locally, as always. Only remote API access becomes unavailable until the connection returns — and the licence tolerates offline periods.

Is it hard to install? Do I need an IT person? +

One installer, paste the subscription key, choose the company — and it turns green in minutes. No consultants, no projects, no opening ports on the router.

I already use another connector for Sage. Is it worth switching? +

elorun exposes Sage through a modern API (REST + JSON), with a secure tunnel included and an AI assistant — and your data always stays on your server. The migration is just a configuration swap; we'll help you do it without any headaches.

Is it safe to let AI write to my Sage? +

Yes — because the AI never writes on its own. The assistant only PROPOSES; you confirm, and only then does elorun save to Sage, with your API key and the write gate you control. Every posting is verified in the database. Reads ("do I have stock?", "how much does the customer owe?") are free; postings always require your OK.

Are the invoices the assistant posts legally valid? +

They are documents signed by Sage itself, with ATCUD and RSA signature — identical to the ones you issue today. The assistant only prepares; nothing is saved without your confirmation.

Still have questions? Talk to us.

Quick reply, no commitment. We'll show you elorun on your Sage.

Connect. Progress. Move.

Your ERP deserves a 21st-century API.
