"Unlimited support" is a genuinely common managed-IT pricing model, and it can be a fair one — but the word "unlimited" is doing a lot of work in a sentence that usually has real limits somewhere else. A provider offering unlimited help desk tickets for a fixed monthly fee still needs the arrangement to be commercially sustainable, which means the boundaries exist; the question is only whether they're visible before you sign or discovered afterward.
The common places those boundaries hide: after-hours or emergency support billed separately from the base fee, on-site visits charged for travel and labour outside the monthly inclusion, and a narrower definition of "support" than a buyer assumes — routine tickets included, but projects, new equipment setup, or anything outside a specific system list treated as out-of-scope work billed at an hourly rate.
None of this makes unlimited pricing a bad model. It makes it a model where the actual value depends entirely on what's excluded, and that detail is exactly what tends to get glossed over in a sales conversation and specified precisely in the contract. The gap between the pitch and the contract is where most billing disputes originate.
The useful question to ask is not "is support unlimited" but "what, specifically, falls outside the monthly fee, and what does that cost when it happens." A provider who can answer that clearly, with examples, is describing a real commercial model. A provider who repeats "unlimited" without specifics is describing a marketing line.
North Ark doesn't sell unlimited support for exactly this reason — a defined scope, response target and included engineering effort, stated plainly, is more honest than a promise with the boundaries left for you to discover.
