Because the contract lives in a filing system and the ticket lives in a helpdesk. An agent under pressure treats every ticket the same, which is generous to the clients paying least and unfair to the ones paying most.
The cost is invisible until somebody works out that the smallest contract generates the most hours.
The customer record carries the contract and its entitlement, so the SLA that applies is on the ticket when it arrives. Business hours, escalations and breach reporting follow from it rather than from an agent's judgement.
Service management is proper: incidents, problems and changes are separate things with their own lifecycles, and a recurring incident becomes a problem rather than a habit.
It is not an RMM and does not monitor, patch or discover devices. It holds the service relationship beside whatever does.
And it will not stop you being generous. It will show you precisely what that generosity costs, by client.
Time on tickets is costed per client, so a managed-service contract that is quietly unprofitable shows in the month rather than at renewal. Loop's project work and Desk's support sit on the same customer.
Asset management holds what you are responsible for, so a ticket resolves against a known device rather than a description.
Products, not integrations. Each one reads the same record, so a join is a permission rather than a sync job with a mapping screen behind it.
Yes, from the contract on the customer record, before the clock starts.
Yes, as separate lifecycles rather than one ticket type.
Yes, against the contract, alongside project work in Loop.
Half an hour on your own numbers is usually enough to say whether Desk is the right place to start.
