Cost and pricing
- How much does an AI agent cost?
A narrow AI agent that handles one task, such as sorting support emails or updating a CRM, is often built by an agency for a few thousand US dollars. - How much does an AI agent cost per month to run?
Monthly cost has three parts: AI model usage (billed per amount of text processed), the platform or hosting it runs on, and support from whoever built it. - How much does an AI voice agent cost?
An AI voice agent has two costs: building it (scripts, integrations with your calendar or CRM, testing) and running it, which voice platforms usually bill per minute of call time. - How much does an AI automation agency charge?
Most AI automation agencies quote a fixed price per project, charge an hourly or daily rate for open-ended work, or sell a monthly retainer for ongoing improvements. - How much does it cost to build an internal tool?
A small internal tool, such as an approval screen or a dashboard on a low-code platform, usually costs an agency build in the low thousands to low tens of thousands of US dollars.
Choosing an agency
- How do I choose an AI automation agency?
Pick an agency that has built something similar to your project, explains things in plain words, builds everything in accounts your company owns, and tells you up front what support costs after launch. - What questions should I ask an automation agency before hiring?
Ask what similar project they have built, which tools they would use and why, who will own the accounts and workflows, how they test and monitor for errors, what happens when an app changes, how long it will take, and what support costs each month after launch. - Should I hire an automation agency or a freelancer?
A freelancer is often the cheapest choice for one or two clearly defined workflows. - What does an AI automation agency actually do?
An AI automation agency finds repetitive work in your business, such as copying data between apps, answering routine emails or preparing reports, and builds software to do it automatically.
Tools compared
- n8n vs Zapier: which is better for a business?
Zapier is usually easier for non-technical teams and connects to a very large number of apps. - n8n vs Make: which should I use?
Make is a fully managed visual builder that is strong at branching and data mapping, good for teams that do not want to run servers. - Power Automate vs n8n: which is right for my company?
If your company runs on Microsoft 365, Power Automate is often the natural first choice because it fits Teams, Outlook and SharePoint and may be partly covered by existing licences. - Is Zapier worth it for a small business?
Zapier is often worth it when a small team needs a few simple automations quickly and nobody technical will maintain them. - What are the best Zapier alternatives?
The most common Zapier alternatives are Make (visual and flexible), n8n (open-source licence options, self-hostable, custom code) and Microsoft Power Automate (best inside Microsoft 365). - Should I use n8n self-hosted or n8n Cloud?
n8n Cloud is run for you, so there are no servers to maintain, and it suits most teams. - Retool vs Power Apps: which is better for internal tools?
Power Apps fits companies that already use Microsoft 365 and Dataverse, because it plugs into those tools and licences.

An AI agent is software that reads a request, decides which steps to take, and then does them in your tools, for example looking up a customer, updating the CRM and drafting a reply. - What is the difference between an AI agent and an automation workflow?
An automation workflow follows the same fixed steps every time, such as "new form, add to CRM, send email". - Can I get an AI chatbot that answers from my company documents?
