ELORUN
Connect · Progress · Move
Your Sage 50c,
connected to the world.
The 2026 breakthrough · AI agent-ready
Talk to your Sage.
elorun exposes your Sage as tools for AI agents (via MCP). Connect your assistant — Claude, ChatGPT — and it starts acting in your Sage in natural language. You ask, it does, you confirm.
Illustrative conversation — the agent uses elorun's tools on your real Sage.
Post documents
Supplier invoices, sales, delivery notes — from a PDF or a sentence.
Real-time queries
"Do I have stock of item X?", "what's the price for customer Y?" — instantly.
Current accounts
"How much does customer Z owe me?", "what do I owe this supplier?"
Delivery notes + AT
Creates the delivery note and reports it to the Tax Authority.
You're in charge. Always.
The AI proposes; you confirm. Writes to Sage only happen with your authorisation — and each one is verified in the database. Reads are free; postings only with your OK.
See it for yourself
elorun in action
This isn't a promise — it's what happens when your Sage gets a modern API and an assistant.
Everything your integration needs
elorun runs alongside your Sage and exposes it with bank-level security.
Full REST API
Sales, purchases, stock, customers, delivery notes — the entire Sage 50c exposed through a modern API, built on the official SDK.
Secure tunnel built-in
Your Sage becomes accessible at your-company.elorun.pt via Cloudflare Tunnel — no open ports, no fixed IP, no router.
Defence in depth
Three independent credentials protect each installation: API key + Access Client ID + Secret. Nothing gets in without all three.
AT reporting
Delivery notes reported to the Tax Authority automatically, with AT code and cancellation within the legal window.
Up and running in minutes
One installer, one subscription key, one company selected — and the indicator turns green. No consultants, no projects.
Always up to date
Signed automatic updates, stable/beta channels, and business rules evolve in the cloud without reinstalling anything.
E-commerce ready
Your Sage catalogue — items, prices, stock and images — exposed to any online store, already without discontinued items.
When Sage gets an API and AI
What you'll automate — and build?
Your Sage stops being an island. Tedious tasks start taking care of themselves — and anything you can imagine connects to your real data, in real time.
Supplier invoicing
PDF or email → the assistant reads, extracts the lines and posts. You just confirm.
Collections without effort
Who owes you and for how long, with automatic reminders before it becomes a debt.
Delivery notes + AT, hands-free
Creates the delivery note and reports it to the Tax Authority on its own.
Reports that come to you
Sales, margins and debts straight to Sheets or Power BI — no manual exports.
Online store always accurate
Real catalogue, prices and stock from Sage — no exports, no overselling.
Field sales app
Prices, stock and orders from a phone, wherever the customer is.
WhatsApp bot
"Do you have item X in stock?", "how much does customer Y owe?" — answered automatically, 24/7.
Customer portal
Your customers view invoices and account statements on their own — fewer phone calls.
Connect to what you already use
CRM, marketplace, group ERP, Excel — Sage starts talking to all of them.
What you haven't imagined yet
It's an open, documented REST API. If you can describe it, you can build it.
And you don't set it up alone — dedicated support.
We design every automation and integration with you — from supplier invoicing to your e-commerce. Human support, in your language, from people who understand Sage and tax compliance.
Always in control
Online, monitored
and 100% yours.
You see the status in real time, manage your subscription in the portal, and your data never leaves your server. elorun is the secure bridge — Sage stays yours.
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.
Replaces paid software
Does what old middleware layers did — in a modern way and with AI.
Why elorun and not the usual
Sage has an API. What was missing was making it modern, secure and easy.

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.
