A spreadsheet is the fastest way to start tracking anything — and one of the slowest things to unwind once a whole team depends on it. The question isn't whether Excel is "good enough," it's whether the hidden cost of keeping it running has quietly overtaken the cost of replacing it.
Keep the spreadsheet as long as it's genuinely faster than the alternative. The moment you're spending real time on version control, permission workarounds, or chasing formula errors, that time is the cost of staying — and it usually adds up faster than teams expect. Custom software doesn't have to mean a huge build; a focused internal tool that replaces the riskiest spreadsheet is often enough to start.
Watch for recurring symptoms rather than a single trigger: multiple people editing the same file and overwriting each other's changes, no way to control who sees what, formula errors causing real business mistakes, or manual copy-pasting between systems. Any one of these on a regular basis is a sign the spreadsheet is now costing more time than it saves.
The spreadsheet itself is free, but the hidden costs — time lost to reconciling versions, mistakes from broken formulas, and work-arounds for missing access control — are real and recurring. A focused custom tool has an upfront cost but eliminates those ongoing losses, and it doesn't have to be a large build to pay for itself.
Yes, if it's built around how the team actually works. The goal isn't to add complexity, it's to keep the simplicity of a spreadsheet-like view while adding the structure, permissions, and automation that a shared file can't provide.
That's actually a good reason to stay with a spreadsheet a bit longer — it's cheap to change while the workflow is still settling. Once the process is stable and the pain points are repeatable, that's the right moment to move it into custom software built around the confirmed workflow.
