Agency vs in-house for AI and automation work: an honest comparison.
We are one of the options on this page, so the useful thing we can do is be specific about when the other two are better.
The decision is usually framed as build or buy, which hides the real question. You are choosing where the knowledge ends up, how fast the first version exists, and what you are still paying for in eighteen months.
A partner team gets a first version into production in weeks and hands it over. An in-house hire builds slower at first and then compounds, provided you can hire well and keep the person interested. A freelancer is cheap and fast and leaves nothing behind unless you insist on it.
All three are correct in different situations. Below is the comparison with our own numbers in it, and a section saying plainly when you should hire instead of calling us.
Side by side
Our column is what we publish and deliver. The other two columns describe what we consistently see clients experience, not a claim about any specific hire or contractor.
When each one is the right answer
Hire in-house when the system is your product or changes weekly
If the automation is core intellectual property, if the rules change with every release, or if someone needs to be in the standup every day, hire. Past a certain volume of continuous work a permanent engineer is simply cheaper than any agency, and the compounding knowledge is real. The two prerequisites are an engineering manager who can hold the bar in an interview and enough work to keep the role interesting, because the failure mode of this route is a good hire leaving after nine months of maintenance tickets.
Use a freelancer when the scope is genuinely bounded
One integration, one scraper, one dashboard, with a written spec and no ambiguity about the outcome. This is the cheapest correct answer more often than agencies admit. Ask for documentation and a handover session in the contract, because the common failure is not quality, it is a working system nobody else can change.
Use a partner team when you need it live before you can hire
The case for us is time and pattern familiarity. A pilot is live in about three weeks from a $4,000 floor, a production build in ten to twelve weeks, and the price is fixed after the audit week rather than estimated before it. You get the code, the documentation, the evaluation suite and an editable workflow, and 98% of clients come back for a second project, which is the number we would judge an agency on if we were buying.
The honest cost comparison
We will not put a fabricated salary in a table. Look up the market rate for a mid-level AI or automation engineer where you are hiring, add 25% to 35% for employer costs, tooling and infrastructure, and then add the management time to hire and supervise. That figure is your baseline.
Against it, our published floors are $4,000 for an automation pilot, $15,000 for a software build and $3,500 a month for ad production, with most projects landing between $15,000 and $80,000. The comparison worth making is not annual cost against annual cost; it is what exists in production ninety days from now under each option.
What actually goes wrong on each route
In-house: the hire takes longer than planned, the first project ships in month five, and the second project is delayed because the same person is now on-call for the first. This is normal, not a failure, and it is why the honest timeline for a first in-house build is measured in quarters.
Freelance: the work is fine and undocumented. Six months later a business rule changes, the freelancer is on another contract, and nobody can safely edit the workflow. This is preventable with a handover clause and almost never prevented.
Agency: you get a system built to a spec that stops matching reality, or a dependency you did not intend to keep. Our answer is handover as a deliverable rather than a promise, in a tool your team can edit, with the evaluation suite included so changes are safe. Coastline chose n8n specifically so their own team could edit the workflow after we left.
The sequencing most companies should use
Buy the first one, hire for the fifth. A partner team gets a working system into production and, more usefully, produces the process map, the written rules and the evaluation set. Those artefacts are what make a later in-house hire productive in weeks instead of quarters.
The reverse order is expensive. Hiring first means your new engineer spends their first two months doing discovery work an audit week would have produced, and the compounding advantage of an in-house team does not start until there is something to compound on.
How to judge any partner, including us
Ask what happens at the end. Where does the code live, who can edit the workflow, is there an evaluation suite, is there documentation, and what does it cost to leave. An agency that cannot answer those in one sentence each is selling a dependency.
Then ask for a number with a method attached. Coastline's 698 hours a month came from their own timesheets: fourteen steps at measured durations, multiplied by batch volume over 90 days, divided by three. A claim you cannot reconstruct is a claim you should discount.
What we do not take on
Staff augmentation by the seat, work where nobody on your side owns the outcome, and projects where the process is different every time and nobody can write the rule down. In the last case the audit week will say so, and you keep the process map either way.
We also say no when the honest answer is a $50 a month tool. That happens more often than a page like this usually admits.
The work behind the numbers

Questions people ask on this one
Per year of continuous work, usually yes. For the first project, usually no, because you are not paying for a hiring round, a ramp or the months before anything exists. The break-even depends on how much continuous work you actually have, which is worth calculating honestly before either route.
You own the code, infrastructure, workflows, evaluation suites and documentation, and we keep no access after the 30-day support window unless you ask us to stay on a retainer. About half of clients take a retainer; the other half edit the workflows themselves, which is why we build them in editable tools.
Yes, and it is the most common arrangement on larger builds. Your team usually owns the product surface and we own the agent layer, the evaluation harness and the rollout, with weekly demos in your stack rather than slides about it.
Insist on the same things we would: an editable workflow in a tool your team knows, documentation written for a successor, an evaluation suite so changes are testable, and a handover session recorded. If a partner resists any of those, that is the answer to the question.
That is a good outcome and we build for it. The process map, the written rules and the evaluation set are exactly what a new hire needs on their first week, and several clients have used a first project with us as the job specification for the role they then filled.
The scoping call happens within a week of your enquiry, the audit runs the week after, and the build starts once the plan is signed. Automations are typically live in three weeks from that point, and production AI builds in ten to twelve.

Thirty minutes, no pitch deck. If the honest answer is the other column, we will say so on the call, and you will leave with the reasoning written down.
