# Custom AI Agents

> Custom AI agents are AI agents built for one organization's specific processes, systems and rules, rather than bought as a general-purpose product. They combine a language model with company-specific instructions, access to internal data, and tools that connect to systems such as the CRM, help desk or ERP, plus the permissions, approval steps and logging the business requires.

## Why it matters for your business

Off-the-shelf AI tools work well for common, standardized tasks, and they are usually cheaper and faster to adopt. A custom agent makes sense when the work depends on your own data, crosses several systems, follows rules a packaged product cannot express, or is core to how you compete. The tradeoff is ownership: a custom agent needs evaluation, monitoring and maintenance as models, APIs and processes change. Buyers should ask who maintains the agent after launch and what it costs each month to run.

## Example

A wholesale distributor builds a custom agent for its inside sales team. The agent reads emailed purchase requests, checks stock and customer-specific pricing in the ERP, drafts a quote in the distributor's format and asks a rep to approve it. Off-the-shelf tools could draft an email, but none could apply the distributor's contract pricing rules.
