AI Automation Agency: What a Good One Delivers, and How to Tell Before You Sign
Half the search results for this term are videos about starting one. That tells you something about the market. Here is what you should get from an AI automation agency, what it should cost, and the questions that sort them in one call. Written by one, so read it with that in mind.
Oct 16, 2026
An AI automation agency takes a process your team does by hand and builds a system where AI does part or all of it: reading documents, updating the CRM, answering routine requests, reconciling orders. A good one connects it to the tools you already use, keeps a person in the loop where mistakes are expensive, and is still there when it breaks six months later. The market is young and mixed. Search for the term and half the results are videos about how to start one. So the useful question is not "which agency" but "which kind", and nine questions sort them in one call. We are one of these agencies, so read this with that in mind. We have tried to write the version we would want to read as a buyer.
The three kinds you will meet
1. No-code workflow builders. They assemble your automation from Zapier, Make or n8n plus a model API. Fast and cheap to start, and the right answer for a simple internal workflow. The limits show when the process has many exceptions, when it writes to your core systems, or when each user needs their own permissions. A canvas of forty nodes is hard to test, and harder to hand to the next person.
2. Software firms that build AI into your systems. They write code: an integration with your ERP or CRM, a service that reads your documents, an agent with tested rules about what it may change. Slower to start and more expensive up front, but you get something that can be tested, versioned, and run like the rest of your software. This is what we do.
3. Consultancies. Strategy, roadmaps, vendor selection, sometimes a proof of concept. Useful when you do not know where to start and have the budget for it. Ask early who builds and runs the result, because it is often someone else.
None of these is wrong. The mistake is buying one when your process needs another.
What a good one delivers
Whatever the kind, you should come out with:
- A process that runs on real data, not a demo on three clean examples. Ask how they will test it on last month's actual volume.
- A clear line between what the AI does and what a person approves, written down before the build.
- Visibility and undo. When the automation changes a record, a person can see what changed and reverse it in one step. Why we prefer that to an approve button.
- A plan for failure. Model providers go down, and billing faults refuse paying customers for hours, as two Claude incidents showed in October 2026. Someone has to be alerted and the process has to degrade gracefully.
- Ownership. The code, the configuration and the accounts belong to you, in the contract.
- A running cost. Models change every few months and someone has to re-test the workflow. If there is no monthly line in the quote, nobody is doing that.
What it costs
Prices vary as much as the agencies do. Template-based no-code builds can start at a few hundred dollars. Custom work that connects to your systems usually starts in the thousands for scoping and the tens of thousands for a first workflow in production.
Ours are published:
| Step | Price |
|---|---|
| Express scoping (one workflow) | $2,300 to $4,700 |
| Full AI audit | $7,000 to $14,000 |
| Audit plus a first workflow in production | from $17,500 |
| Running it afterwards | from about $470 per month |
The model calls are usually the smallest line. We read 13,000 insurance documents for under $25 in model costs, by choosing the model per task. The full breakdown is in how much it costs to build an AI agent.
Nine questions to ask on the first call
- Show me something you built that is in production today. Who uses it, how often, and since when? A demo video is not an answer.
- What would you not automate in our process? An agency that says "everything" has not looked.
- Who owns the code, the workflows and the accounts? If the automation lives in the agency's own Zapier or n8n account, you do not own it.
- What happens when the model provider is down or our credit runs out? Listen for alerts, retries that stop, and a fallback for the user.
- How does a person see and undo what the automation did?
- How do you test it before it touches real data, and on how much data?
- Whose permissions does it use? It should act with the rights of the person who triggered it, not with an admin key that can see everything.
- What does it cost per month after launch, and what does that include?
- If we stop working together, what do we keep, and can someone else run it?
The good ones answer these in a sentence each. The rest is sales.
Where we fit
We are a software firm of the second kind. We write the integrations and agents in code, run them on infrastructure we operate, and keep them running for a monthly fee. In production today: the quotation platform Casa Europa's sales reps use, and MCP servers that let Claude work inside our clients' own software, such as the platform we run for an accounting firm. We are not the cheapest option for a simple internal workflow. If yours is one, we will tell you to try n8n first.
