Frequently asked questions
An artificial intelligence (AI) agent is a system capable of perceiving its environment, reasoning based on available information, and acting autonomously to complete a task. Unlike traditional automation, AI agents can adapt, interact with their environment, and operate with their own judgment — executing tasks with speed, precision, and context, just like a human would, but with greater scale and consistency.
At Payana, we're building three types of agents:
- Assistants: Review and analyze information to recommend actions such as account ingentries.
- Operators: Execute tasks under predefined rules, like ordering payments by due date, recording invoices, or reconciling transactions.
- Specialists: Integrate information across systems and coordinate complex flows — such aspayments, reconciliations, and reports — ensuring precision and coherence at every stage.
This approach allows us to move toward a future where financial processes run on their own and human teams focus on higher-value strategic activities.
Unlike traditional automations, AI agents can adapt, interact with their environment, and operate autonomously. They can execute tasks with speed, precision, and context, just like a human would, but at greater scale.
At Payana, we are building three types of agents:
- Assistants: Recommend actions that require human validation. Example: suggesting reconciliations between invoices and purchase orders.
- Autonomous: Execute tasks within predefined rules. Example: scheduling and executing automatic payments for invoices below a certain amount.
- Coordinated Teams: Multiple specialized agents collaborate to execute complex processes. Example: a cash flow created by accounts payable, accounts receivable, and financial analysis agents.
This approach allows us to move toward a future where financial processes run on their own and human teams focus on higher-value strategic activities.
