SLA Basics for Solo Freelancers
Service Level Agreements aren't just for enterprise contracts. Here's how to set response times and expectations that protect both sides.
A client emails at 11pm: "Urgent change needed — can you push this before tomorrow morning?" You didn't sleep well. You made the change. You sent it by 8am. The client replied at noon asking for an update.
Nobody agreed to that schedule. But nobody said anything different either.
A Service Level Agreement (SLAA written commitment about your availability and response times. It answers "what can I expect from you?" before a client has to ask.) is a written answer to the question every client has and most freelancers never address: what can I expect from you? Business hours. Response time. What "urgent" means and what it costs. That's most of it.
What goes in an SLA
Response time
How quickly you respond to a client inquiry. This is acknowledgment time, not resolution time. "I respond to emails and messages within one business day during business hours" is a reasonable baseline. You can add tiers: urgent requests (same business day, higher rate) vs. standard requests (one to two business days).
The NIST definition of an SLA describes it as a documented agreement specifying services, responsibilities, and priorities. For freelancers it's the same idea: write down what you'll provide and when, so nobody is improvising the terms mid-crisis.
Business hours
When you're available. State your time zone. State the days. "Monday through Friday, 9am–6pm Eastern Time. I am not available on weekends or public holidays." This one line cuts most 11pm urgency requests — not because clients stop sending them, but because you have something in writing when you reset expectations.
Revision turnaround
How long revisions take after feedback arrives. "Revisions are delivered within three business days of receiving written, consolidated feedback" is standard for design and development work. "Within one business day" is reasonable for small copy edits. Name the number. "As soon as possible" is not a number.
Escalation path for urgent work
What happens when something is genuinely urgent: a launch is tomorrow, a client's external deadline moved. Define how a client flags something as urgent and what that means for your response. "Urgent requests outside business hours can be flagged via [method] and will be addressed within four hours. Urgent turnaround is billed at 1.5× the standard rate." This gives the client an actual option. It also makes "urgent" mean something specific.
BreachWhen one party fails to meet their obligations under the contract. Missing a deadline is breach. Not paying is breach. Naming breach consequences turns a vague violation into an actionable event. consequences
What happens if you miss an SLA? Name it. Service credits, deadline extensions, partial refunds — whatever fits your type of work. According to Nolo's contract law reference, breach remedies work best when they're pre-agreed and proportionate to the missed commitment. "I'll redo it for free" is vague. "Delivery extended by one business day per day of delay" is specific and enforceable.
What an SLA is not
An SLA doesn't replace communication. If you're behind, say so. If something changed, tell the client. Think of it less as a legal tool and more as a document you agreed on at the start and hopefully never need to pull out again. What it buys is predictability: the client knows what to expect from you, and you know what you've committed to.
When this matters most
For retainerAn ongoing arrangement where a client pays a fixed monthly amount for defined services or availability. The deliverable is access to you, not a specific output. work — monthly arrangements where ongoing availability is expected — an SLA is not optional. Without one, a retainer is an open-ended commitment with no defined scope. That's how you end up working weekends you never agreed to, on work that wasn't part of the deal.
For project-based work, a two-paragraph SLA section in your standard contract handles most situations. If you're mid-project with a client who has unclear expectations, you can introduce it as a "wanted to get this in writing" message. Most clients take it as normal, not defensive.
Summary
Paste this into your contract template. Adjust the numbers to match your actual working hours and rate structure.
- Business hours: Monday–Friday, [start time]–[end time] [time zone]. I do not provide service on weekends or public holidays unless separately arranged.
- Response time: I respond to all client messages within [1–2] business days during business hours. Requests flagged as urgent are acknowledged within [4] hours and billed at [1.5×] the standard hourly rate.
- Revision turnaround: Revisions are delivered within [2–3] business days of receiving written, consolidated feedback. Feedback submitted after [3pm] is treated as received the following business day.
- Breach: If a scheduled delivery is delayed by more than [2] business days without prior written notice, [describe remedy: project credit, extended timeline, partial refund]. This does not apply to delays caused by late client feedback or approvals.
