Seats and usage diverge quickly. A client paying for two hundred licences with sixty active people will not renew, and noticing that six months before the renewal date is the difference between a conversation and a cancellation.
Expiry dates are a diary of future revenue. Certification that lapses in ninety days is a client who must buy again, and a provider who contacts them first is rarely compared with anybody else.
Regulation moves and content ages instantly. When a rule changes, every course covering it is wrong on the same day, so knowing which clients hold which version decides how fast the problem is contained.
The report is half of what was bought. A client facing an audit needs to show who trained, when and with what result, and producing that on request is the part of the service that gets remembered.
