What the build 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.
A typical scope
- The agent's instructions and decision logic
- Tools it can call, such as APIs, databases and search
- Memory or retrieval over your data
- Guardrails and approval steps for risky actions
- Evaluation runs and logging of what the agent did
Systems it usually connects to
- Shopify or WooCommerce
- Klaviyo or another email platform
- Helpdesk tools such as Gorgias or Zendesk
- Inventory and shipping systems
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. Fixed-price posts state a median of $300, while hourly posts work out at $7,200 on our estimate: 24 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
