# Service levels These are the commitments that hold on every engagement from the day it is confirmed. For a system we run on your behalf, the figures — how quickly we respond, which hours are covered, how much of the time it must be available — are set in writing for that system, and that agreement is where they live. ## When you write to us Write to [welcome@engineer.company](mailto:welcome@engineer.company) or call [+45 50 10 61 84](tel:+4550106184) . A person reads every message the same day, and the reply comes from somebody who works on your engagement rather than from a ticket system. ## Defects in what we deliver **Defects in delivered work are fixed at our cost for 90 days after delivery.** That is a term of the [contract](/terms/), not a goodwill gesture. A defect is the work not doing what was agreed; something new that you need is a change, and it is handled as one. ## Changes along the way When something new arrives mid-engagement, we say what it adds in time and money before doing it, and you decide. Nothing is absorbed silently and presented as a surprise at the end. ## Systems we run for you When we operate a system on your behalf, its service levels are written into the agreement for that system: the response time for an incident, the hours that are covered, the availability it is held to, when maintenance may happen and how you are told about each. They are set per system because a nightly report and a payment service need different answers, and a single figure here would be too loose for one and more than the other needs. A weakness found in anything we operate can be reported to [welcome@engineer.company](mailto:welcome@engineer.company), as the [security](/security/) page describes. We confirm receipt and tell you what we are doing about it. ## The people and the handover The people named in the engagement are the people who do the work. What we deliver comes with the documentation your own people need to run it without us. Ongoing work can be ended by either side with 30 days' written notice, and whatever the reason, you get a handover: code, access, credentials and an explanation of where things stand. ## What binds us This page describes the defaults. The [terms of business](/terms/) are the contract, and a signed agreement between us comes before both: where they differ, the signed agreement wins.
