What the demo contains
Most tool demos show an empty shell in which data first needs to be created. This one is populated: a sample company with an established IT landscape across seven categories, covering mobile, fixed-line and WAN, Unified Comms, data centre, software and licences, hardware, Techfund and recurring invoices.
Every category has providers, contract expiry dates and cost history. Invoice review checks against the price in the contract, using the same mechanism as for an actual tenant.
Cost overview
Twelve months of spend by category and provider, with trends and anomalies.
Invoice review
Every invoice checked against the agreed price. If it differs, the discrepancy and its amount appear in the cockpit.
Provider catalogue
All providers with address, status and contract expiry in one place, instead of five Excel files.
Renewal early warning
Anything expiring in the next 90 days appears at the top, with the provider, value and notice period rather than just a date.
