Confessions from Spreadsheets Anonymous (and the way out)

Let’s be honest: spreadsheets are fantastic for analysis and quick “what happens if…?” noodling. But once you try to run an enterprise IT planning cycle in them—across dozens of budget owners, thousands of line items, shifting headcount, contracts and renewals, cloud commitments, and allocations—the wheels wobble.

To put a financial lens on the problem, this could result in millions of dollars of wasted labor hours, misaligned costs driving the wrong business decisions and tens or hundreds of millions of dollars of capital not being deployed against strategic priorities.

Here are some of the top reasons why spreadsheets stall planning:

• IT planning needs detail that spreadsheets can’t carry
• Version sprawl and errors block a single source of truth
• Answers that should take minutes, take weeks
• Rolling and multi-year planning breaks down in spreadsheets
• See eBook for full list

IT and Finance are solving the same problem from different directions. IT thinks in services, applications, business capabilities, infrastructure, vendors, and people. FP&A needs cost center and account by period. The translation step—done well—turns IT’s operational intent into numbers Finance can book and defend, without losing the detail IT needs to run.

This translation is where spreadsheet-based processes most often fail. A more sustainable approach treats translation as a repeatable pattern, not a manual rebuild, allowing IT and Finance to work from the same plan without compromise.

Moving IT planning into an IT Financial Management (ITFM) platform does not mean abandoning spreadsheets entirely. Instead, it means redefining their role. Spreadsheets remain valuable as personal analysis tools, while the planning process itself—intake, approvals, versioning, and publishing—moves into a governed environment.

In this model, changes are captured once, reviewed in context, and published with clear ownership and timing. Budget owners work in familiar operational terms. IT finance teams apply guardrails. Finance receives consistent, reconcilable outputs. Most importantly, everyone works from the same version of the plan.
