How much does it cost to hire an AI agency?
The cost of hiring an AI agency depends on scope, not a single number. As a rough guide, simple automations and proofs of concept run from the low thousands to low tens of thousands, mid-sized custom builds commonly land in the tens of thousands, and large or regulated enterprise systems can reach six figures. The main cost drivers are complexity, data readiness, integration depth, and compliance. Any range is indicative — scope the project and get a quote against a Statement of Work.
Figures below are broad market indications to help you budget, not quotes. Actual pricing varies widely by scope, region and agency.
Typical project ranges
Proof of concept / simple automation
Low thousands to low tens of thousands. A scoped prototype, a simple workflow automation, or a basic chatbot to validate an idea.
Mid-sized custom build
Tens of thousands. A production chatbot, a RAG application over your own documents, or a meaningful process automation with integrations.
Large / enterprise / regulated
Into six figures. Complex multi-system integrations, custom model training, high-compliance environments, and ongoing managed support.
What actually drives the cost
Project complexity
A simple automation or a scripted chatbot is far cheaper than a custom-trained model, a retrieval system over your own data, or an agentic workflow. The sophistication of the AI is the first-order cost driver.
Data readiness
If your data is clean, labelled and accessible, you save significant time. If it needs collecting, cleaning or structuring first, expect that to be a meaningful line item on its own.
Integration depth
A standalone tool is cheaper than one wired into your CRM, ERP, support desk and internal systems. Every integration adds scope, testing and maintenance.
Compliance and security
GDPR obligations, EU AI Act responsibilities, and enterprise security requirements add design, documentation and testing work — necessary, but they move the number.
Support and maintenance
AI systems drift and need monitoring, evaluation and updates. A one-off build costs less upfront than an ongoing managed engagement, but budget for the lifecycle, not just the launch.
Get to a real number faster
The way to turn a range into a quote is a clear scope. Once you know what you need, the pricing model determines how you pay, and specific builds like a chatbot or a custom LLM/RAG app have their own cost profiles. If you're weighing whether to hire at all, see is hiring an AI agency worth it.

Frequently asked questions
How much does it cost to hire an AI agency?
It depends on scope, not a single figure. As a rough guide, small proofs of concept and simple automations often run in the low thousands to low tens of thousands, mid-sized custom builds (a production chatbot, a RAG application, a workflow automation) commonly fall in the tens of thousands, and large or regulated enterprise systems can reach six figures. The biggest cost drivers are project complexity, data readiness, integration depth, and compliance requirements. Treat any range as indicative and get a scoped quote against a Statement of Work.
What makes an AI project more expensive?
Cost rises with complexity of the AI itself, the amount of custom integration into your existing systems, poor or messy data that needs cleaning and preparation, strict compliance requirements (GDPR, EU AI Act, security), and the level of ongoing support and maintenance you need. A clear, narrow scope is the single most effective way to control cost.
Should I choose an AI agency on price alone?
No. The cheapest quote is often the most expensive outcome if the project fails or has to be rebuilt. Compare quotes on scope, deliverables, and risk protection — a clear Statement of Work, milestone-based escrow, and a verifiable track record — not just the headline number.
