How much does an AI agent cost for an SMB? (Spain, 2026)
Almost nobody in the sector publishes prices. Here are the ranges that ARE verifiable on public websites as of July 2026, plus the full breakdown of what you would pay with Evy.
The short answer
It depends on how you build it. Custom development is paid per project and costs thousands of euros; segment SaaS starts at about EUR 49/mo; and a managed agent like Evy's starts at EUR 19.99/mo with the server included, plus AI usage above the allowance. All three routes are valid for different cases: the difference is project size and who does the maintenance.

The full cost with Evy, no fine print
The plan (EUR 19.99, 26.99 or 39.99 per month) includes the setup, channels, maintenance and an AI allowance of EUR 2, 5 or 10 per month depending on the plan.
On top of that comes a single extra cost, and a transparent one: the model's usage once you exceed the included allowance. The server is part of the plan (Standard included; Medium +€14.99/mo; Large +€48.99/mo; Extra large +€99.99/mo). Your AI budget has a cap: when it runs out, the agent pauses and nobody overcharges you.
Custom, SaaS or managed? When each one pays off
Custom: when you need deep integrations with in-house systems no standard product covers. The most customizable option and the most expensive; maintenance is contracted separately.
Chatbot SaaS: when your case is narrow and you do not mind your data living in the vendor's cloud. Quick to set up; you pay per conversation or per plan.
Managed on your server: when you want the agent to be yours (your data, your server, not tied to a vendor) but you do not want to touch a terminal. That is Evy's slot.
The quick math
A managed agent starts at EUR 19.99 per month. Developing a custom chatbot costs EUR 5,000-10,000 in its simplest form and EUR 15,000-50,000 with advanced conversational AI (Yeeply, 2026); a full AI-agent rollout for an SMB runs about EUR 3,000-15,000 per project (Javadex, 2026). If your case does not demand one-of-a-kind development, the difference is not measured in percentages: it is measured in orders of magnitude.
