How much does an AI agent cost to build and run?
Budget for the build and the running costs separately. The build depends on the job, integrations and testing; the monthly bill depends on usage, hosting and the support you agree. A model bill alone is not the full cost of an agent.
What does the build cover?
A custom AI agent needs a defined job, access to the right information and a way to use your business tools. The build pays for that working system: mapping the task, connecting the agreed tools, testing difficult cases and handing it over.
A question-answering assistant working from a small set of approved documents is a different project from an agent that changes bookings, checks payments and prepares reports. Compare the actions and integrations in the proposal before comparing its headline price.
| Part of the work | What to define |
|---|---|
| The job | One repeatable task, its exceptions and what a successful result looks like. |
| Business information | Which records and documents the agent can read, and whether they need preparation. |
| Integrations | The systems it connects to, the actions it can take and the access each system supports. |
| Controls and testing | Human approvals, access permissions, failure handling and representative test cases. |
| Rollout and handover | Migration, staff training, documentation and who will run the system after launch. |
At neu, the build price is agreed after scoping. Our AI agent development service starts with a free 30-minute review to identify a useful first release, rather than attach one price to every kind of agent.
What does an AI agent cost each month?
Separate usage from the cost of keeping the system running. Your recurring budget can include:
- AI usage: the model work needed to read a request, use tools and prepare a result. Longer documents, additional steps and retries change the usage per task.
- Connected services: any messaging, voice, CRM or other service charges your workflow needs.
- Hosting and storage: the application, database, files, logs and monitoring used by your setup.
- Ongoing care: the monitoring, fixes and improvements included in your agreed support arrangement.
Ask which costs you pay directly, which a supplier passes through and which are included in a recurring fee. An inexpensive model call does not tell you the total cost of a production workflow.
Work through a running-cost example.
Take a hypothetical agent completing 3,000 tasks per month. At an assumed AI cost of €0.02 per completed task, the AI portion would be €60. Add an assumed €100 for other monthly costs and the recurring budget becomes €160, or €1,920 over a year.
Those numbers illustrate the arithmetic. They are not neu prices, a market average or a live model-provider rate. Your build quote is separate. Replace the assumptions below with your expected volume and the costs your suppliers confirm.
Try your own assumptions.
The starting values are a hypothetical example, not neu prices or a current provider rate. Replace them with the usage and costs in your own quotes.
€1,920.00 over 12 months at the same usage.
This excludes the upfront build. Check whether your supplier quotes include applicable tax. Use a per-task estimate that reflects the model calls and retries needed to complete the work.
Use a realistic completed-task cost. If answering one enquiry takes several model calls, include all of them. If a workflow sends WhatsApp messages, add its messaging costs separately; our WhatsApp chatbot cost guide explains that part of the bill.
Make the first release small enough to measure.
Start with a task your team repeats often and can describe clearly. Record how long it takes today, how often it needs correcting and where a missed handoff creates work. That gives you a baseline for judging the agent alongside its build and running costs.
For example, our tutoring operations case study covers tutor check-ins, parent reports and payment reconciliation through WhatsApp. The scope is the complete operational job, including the records and handoffs behind the conversation.
If the work follows predictable rules and needs no interpretation, ordinary workflow automation may be a better fit. Decide on the task before deciding that it needs an agent.
What should an AI agent quote include?
- The workflows, users, channels and integrations included in the first release.
- The information the agent may access and the actions that require a person’s approval.
- The acceptance checks, difficult cases and rollout support included in the build.
- The expected usage, recurring charges and process for approving additional spend.
- Code ownership, account access, documentation and the support or handover arrangement.
Compare the first-year budget as well as the build fee: the agreed upfront price plus expected recurring costs over 12 months. Ask what changes when usage grows, a provider changes a price or you add another workflow.
Common questions about AI agent pricing
Is a chatbot cheaper than an AI agent?
A narrower job is usually less work to scope and test. A chatbot that answers approved questions may need fewer integrations than an agent that changes bookings or records. Compare the actual work included; the names alone do not define a price.
Can an Irish small business start with one workflow?
Yes. neu is a Dublin software studio working with businesses in Ireland and internationally. We can scope one useful task, agree its integrations and success checks, and expand the system through separately agreed releases.
Do I pay for every message or every completed task?
That depends on the services in your setup. Your proposal should identify how each supplier bills and how that usage relates to your business workload. A per-task number in a budget is an estimate that combines those underlying costs, not a universal billing unit.
Does neu publish one fixed AI agent price?
No. We agree the build, third-party usage and any ongoing support after defining your workflow. The example calculator is a budgeting aid, not a quotation. Bring your task and tools to a free review for a scoped next step.
