The cheapest support option isn’t the one with the lowest monthly price. It’s the one that answers the phone when something breaks.
The classic trap is the support contract that looks like a bargain: a big monthly fee, a call centre, tickets that sit for days, and a technician who has to be briefed on your setup from scratch every single call.
Real support starts with someone who knows the system because they maintain it — not because they read a manual. It means plain answers, no sales pressure to buy “unlimited calls you’ll never make”. Sometimes the right answer is: “don’t buy that, it’s not worth it.” Trust a supplier who’s willing to say that.
