Arios plugin
Connect Claude, ChatGPT or Codex to your company in Arios. The assistant reads your accounts and your bills, brings new invoices in, and prepares a bill payment for you to submit.
The plugin never moves money. It has no tool that submits a payment and no tool that approves one. You submit every payment yourself in Arios, with the supplier and the amount in front of you.
What it does
| Skill | What happens |
|---|---|
connect-arios | Reports the connection: the companies it was approved for, and what it can do in each one |
collect-bills | Brings an invoice into Arios as a bill, sends the PDF, and lets Arios read the fields off the document |
spend-summary | Answers a spend question from your transaction feed |
pay-bill | Prepares the payment draft and gives you the link. You submit it in Arios |
The assistant picks the right skill from what you ask. In Claude Code you can also start one by its
name, for example /arios:collect-bills.
In Claude Code and Cowork, the reader agent answers questions about accounts, balances,
transactions and bills. It only reads.
