+
+Custom agents let you automate expense report review by giving an AI agent specific instructions — like rejecting non-business expenses or flagging reports over a set amount. Instead of manually reviewing every report, you define the rules and the agent handles the rest.

+# FAQ
+
+## What kind of instructions can I give an agent?
+
+You can write natural language instructions that tell the agent how to handle expense reports. For example, you can instruct an agent to reject expenses for non-business reasons, flag reports above a dollar threshold, or remind users to attach receipts.
+
+## Can I have multiple custom agents?
+
+Yes. You can create multiple agents, each with different instructions for different review criteria.
