## What it includes

A custom AI agent is software that uses a language model to plan steps and act across tools and data, rather than answering a single prompt, so it can complete multi-step work with limited supervision.

E-commerce builds are shaped by the store platform. Most work connects to Shopify or a similar system, and has to handle catalogue data, orders and returns accurately during peak trading.

- Tools it can call, such as APIs, databases and search

- Evaluation runs and logging of what the agent did

## What drives the cost

Work expected to take under a month has a median of $500, against $15,250 for over six months. Part of that gap is built in, because hourly estimates are calculated from expected length.

One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
