A technology assessment is a review of the systems the sites depend on to trade: the phone system, the internet circuits, the firewalls, the cloud services, and the contracts sitting behind all of them. It covers every location, and it treats them as one business rather than a pile of separate bills.
The review starts from what the business needs, not from a product, so the answer can be that the current setup is fine.
T Advisors is independent: no provider owns any part of the firm. The client pays no fee for the assessment. When the client chooses a new provider, the client signs directly with that provider at the same price it would pay buying direct, and the provider pays T Advisors. This is explained at the start of every engagement, and the assessment can still conclude that nothing should change.
Most companies have never had this done, and not because they were not paying attention. The information genuinely exists. It just lives in invoices, inboxes and a few people's heads, spread across every office, and no one has ever had a reason to pull it into one place.
