The pain

What it costs you today

In a firm running 220 internal applications across core systems, productivity tools, contracted SaaS and cloud apps, nobody knows exactly how many there are, who owns each one, or what happens when the owner resigns. When a developer asks for a new SaaS nobody knows whether something similar already exists, and when the owner of a critical app leaves the system ends up with no contact and eventually falls over. Architecture and IT lose 12 to 18 hours a week answering "do we already have something for X", while SaaS spend bloats with duplicate subscriptions that have been paid for months. "We spent USD 35,000 a year on a SaaS that does the same as the internal app we already had" was the finding from the last spend review. How much money are we burning on redundant software?

The value

What changes when you have it

A living catalog in SharePoint with a structured list per app, owner, tier 1/2/3 criticality, technical dependencies, monthly cost, active users, renewal date and next review, plus a search web part with filters that the developer uses before requesting a new SaaS. Power Automate alerts the owner 60 days before renewal and fires an obsolescence review when an app has had no commits in 6 months. Architecture and finance see a cost-by-category, detected-redundancy and bus-factor-risk dashboard. The visible output is the catalog with search and the portfolio dashboard. The solution is in production at an insurer with 180 internal apps where the last spend review identified USD 120,000 a year in redundant subscriptions. The investment pays back with the first round of rationalisation.
