You built the agent. It works. The client is happy for about three weeks. Then a vendor changes an API, the agent misfires on a Tuesday morning, and you are suddenly in an argument with no referee.
An AI agent SLA is a short written agreement that defines what your agent covers, when it is expected to run, how fast you respond when it breaks, and what the client pays for that coverage. SLA stands for service level agreement, and it is the document that turns a working automation into a renewable offer instead of a one time favor.
Most solo operators skip it. They quote a build, deliver the build, then absorb every support request for free because nothing was ever written down. That is not generosity. That is an unpriced liability sitting on your calendar.
Key takeaways
- An AI agent SLA is a written agreement covering scope, availability, response time, and commercial terms for an automated workflow.
- The PACT Standard organizes an AI agent SLA into four parts: Perimeter, Availability, Correction, and Terms.
- Microsoft states that Azure OpenAI offers an availability service level agreement for all resources and a latency service level agreement for provisioned managed deployments, which is the model an independent operator can copy at small scale.
- Never commit to uptime you do not control, because your agent depends on third party model providers and platform vendors.
- Monitoring does not have to cost anything to start. UptimeRobot’s free plan includes 50 monitors at a five minute check interval.
- A written correction window, for example a response within four business hours, is what makes a monthly retainer defensible instead of arbitrary.
Why your offer stalls without an AI agent SLA
A buyer is not really purchasing a workflow. They are purchasing the removal of a worry. If the agent handles their inbox, what they actually bought is not having to check the inbox. The moment they cannot tell whether the agent is working, the worry comes back and the value of your offer drops to zero in their head.
That is the gap the agreement closes. It tells the client, in advance, what “working” means, how they will know, and what happens when it stops. Without that, every renewal conversation becomes a feelings conversation. With it, the renewal is a math conversation, which is a much easier one to win.
This is also the difference between a project and a business. A project ends. An agreement renews. If you are moving from one off builds toward an AI agent retainer, the SLA is the piece of paper that makes the retainer make sense to the person paying for it.
I spent sixteen years building automation inside large enterprises. Every production system I touched had an agreement behind it before it was allowed to run unattended. Nobody signed off on a bot because it demoed well. They signed off because someone had written down who gets called at 2 a.m. Solo operators are running production systems for clients now. The paperwork standard did not disappear just because the team got smaller.
The PACT Standard: four terms every AI agent SLA needs
PACT is a four part checklist for writing an agreement you can actually honor as a one person operation. Perimeter, Availability, Correction, Terms. Work them in order, because each one narrows the next.
P is for Perimeter
Write down exactly what the agent covers, then write down what it does not. The second list matters more than the first. It is the list you point to when a client asks whether the agent can also handle their new lead form.
Name the specific inputs, the specific outputs, and the specific systems it touches. “Handles email” is not a perimeter. “Reads the shared support inbox, drafts a reply, and files a labeled draft for human send” is a perimeter. If you have already scoped a productized AI service, most of this section is copy and paste from your scope document.
Anything outside the perimeter is a change request with its own price, not a favor.
A is for Availability
State when the agent is expected to run and how the client can verify it. Be careful here, because this is where solo operators overcommit. Your agent sits on top of a model provider, an automation platform, and whatever apps it connects to. You do not control any of them.
The honest version of this clause separates your work from your vendors’ work. Microsoft, for example, publishes an availability service level agreement for all Azure OpenAI resources and a separate latency service level agreement for provisioned managed deployments. Enterprise vendors draw that line explicitly. So should you. Commit to your configuration and your monitoring, and name the upstream dependencies as excluded.
Then give the client a way to see status without asking you. A free monitor is enough to start: UptimeRobot’s free plan includes 50 monitors checking every five minutes, which covers a small book of clients. While you are defining what the agent can reach, revisit your agent permissions, because an availability promise on a system your agent cannot reliably access is a promise you will break.
C is for Correction
Correction is your response commitment, and it is the clause clients read first. Two numbers do the work: how fast you acknowledge a reported failure, and how fast you either fix it or fall back to a manual process.
Pick numbers you can hit on your worst week, not your best one. A four business hour acknowledgement and a next business day fix or fallback is a serious commitment for a solo operator and it is achievable without wrecking your life. A one hour acknowledgement sounds better in a proposal and will eventually cost you the account when you miss it.
Define the fallback in writing too. Every agent needs a documented manual path, so a failure degrades to slower work rather than stopped work. Running a build in shadow mode testing before go live is how you find out what actually breaks, which is how you set a correction window you can defend.
T is for Terms
Terms is the commercial half: price, billing cycle, review cadence, change request handling, and cancellation. Keep it plain. State the monthly price, state what it includes, state what is billed separately, and state the notice period on both sides.
Two items solo operators forget. First, who pays for platform and model consumption. Decide whether the client holds their own accounts or whether you rebill, and put your cost per run math behind that decision so a heavy month does not erase your margin. Second, a scheduled review. A quarterly fifteen minute review is where you show the numbers and where expansion work gets discovered, which is worth more than the fifteen minutes costs you.
Example scenario: an inbox triage agent on a monthly agreement
Example scenario, not a client result. A local insurance agency wants their shared quotes inbox triaged. Here is what PACT looks like written out.
- Perimeter. The agent reads the quotes inbox, classifies each message into new quote, existing policy, or spam, drafts a reply for the first two categories, and saves the draft unsent. It does not send email, does not touch the policy system, and does not handle claims.
- Availability. The agent runs every fifteen minutes on business days from 7 a.m. to 7 p.m. Central. Status is visible on a public monitor page. Outages caused by the model provider, the automation platform, or the client’s email provider are excluded from the commitment and reported, not absorbed.
- Correction. Failures acknowledged within four business hours. Fixed or moved to the documented manual triage checklist by the end of the next business day.
- Terms. Flat monthly fee stated in the agreement. Platform and model usage billed to the client’s own accounts. Up to one change request per month included, larger changes quoted separately. Thirty days notice to cancel, either side. Quarterly review call.
Notice what is missing. There is no income figure, no promise about how many hours it saves, and no language about results. Everything in that agreement is something the operator directly controls. That is the test. If you cannot control it, do not sign your name under it.
Action steps for this week
- Take your most recent build and write its perimeter on one page, including the exclusion list.
- Write your availability window and list every upstream vendor the agent depends on. Those vendors go in the exclusions.
- Set up a free uptime monitor and give the client a status link so they stop asking you whether it is running.
- Pick your two correction numbers based on your worst week, then write the manual fallback checklist that backs them up.
- Add price, change request handling, notice period, and a quarterly review to the terms section, and send it to your existing client as a version 1 for signature.
If you are still in uniform and planning your transition, this is a document you can practice writing now. DoD SkillBridge eligibility opens to service members with 180 days or fewer remaining before discharge, and an industry placement is a reasonable place to see how real operational agreements are written before you write your own.
Frequently asked questions
What is an AI agent SLA?
An AI agent SLA is a written service level agreement that states what an automated agent covers, when it is expected to run, how quickly the operator responds to failures, and the commercial terms of that coverage. It is the contractual layer that sits on top of a working automation.
Should a solo operator promise a specific uptime percentage?
Usually no. A percentage commits you to the reliability of every vendor in your stack, and you do not control the model provider or the automation platform. Commit to a run schedule, monitoring, and a response window instead, and list upstream vendor outages as excluded.
What does it cost to run an agent under an agreement like this?
Platform cost is usually the smaller half. n8n’s Starter cloud plan is listed at 20 euros per month billed annually with 2,500 workflow executions, and its Pro plan at 50 euros per month with 10,000 executions. Model usage is billed separately by the provider and varies by volume, so measure it before you quote a flat fee.
How long should the agreement be?
One to two pages. A short agreement a client reads and signs beats a long one they skim. Every clause should be something you would actually enforce, and anything you would not enforce should come out.
What happens if I miss my own correction window?
Say so before the client notices, and state the remedy in the agreement in advance. A prorated credit for the affected period is standard and easy to administer. The credit is not the point. The point is that a defined remedy stops one bad week from turning into a lost account.
To recap
An AI agent SLA is what converts a working build into a renewable offer. The PACT Standard gives you the four sections: Perimeter defines the boundary and the exclusion list, Availability states the schedule and names the vendors you do not control, Correction sets response and fallback numbers you can hit on a bad week, and Terms covers price, change requests, notice, and a review cadence.
Write the version 1 this week for the client you already have. It is a one page document, and it is the difference between a build that ended and a system that keeps paying.
