The Spend to Revenue Worksheet

What does this software actually do for the business? You can answer it for the line item that costs the most. You can probably answer it for the next two or three. Past that, the answers collapse into "the team uses it" or "we have always had it."

The Spend to Revenue Worksheet is a structured way to push past those answers. Every line item maps to one of six categories with a defined relationship to revenue. The mapping is not a quantitative ROI calculation; it is a qualitative classifier that tells you whether a particular dollar is buying revenue, enabling it, protecting it, or running operations.

Once every line is classified, the picture is usable. Finance leadership can see what fraction of software spend goes to which band. Procurement can prioritize negotiations on the highest-band categories. The board deck answers a real question.

The six categories collapse into four ROI bands:

• Direct: revenue is harder to attribute later. You cut these tools and the revenue team starts missing quarters.
• Enabling: the team productivity layer. You cut these and everyone gets slower.
• Compliance: the cost of being allowed to operate. You cut these and you cannot sell, cannot raise, or get sued.
• Operating: back office and experimental. You cut these and operations get harder, but revenue does not move for several quarters.

Healthy SaaS portfolios sit at roughly 35-40% Direct, 25-30% Enabling, 10-15% Compliance, 15-25% Operating. Numbers outside these bands do not necessarily indicate a problem; they indicate a question worth asking.

Take any line item from your AP system and ask the four questions in this order:

1. Does the revenue team use it to source, close, or retain? If yes, Direct. CRM, sales engagement, conversation intelligence, customer success: Direct.
2. Does the customer touch it, or does the product depend on it in production? If yes, also Direct. Cloud infrastructure, observability, support tooling: Direct.
3. Does every employee use it to do their job? If yes, Enabling. Collaboration, document storage, AI assistants: Enabling.
4. Is a regulator, auditor, or buyer requiring it? If yes, Compliance. Vanta, cyber insurance, legal hold: Compliance.

Anything that does not fit those four buckets is Operating (back-office) or Experimental (pilots and bets).

Some tools genuinely span categories. AI assistants are the common case in 2026: developers use them as Direct (they build the product faster); other functions use them as Enabling (everyone gets faster). The right move is to split the line. If 70% of seats are with Engineering, classify 70% as Direct and 30% as Enabling.

The split is approximate. The point is not precision; the point is to avoid mis-classifying a six-figure tool as one band when most of its value lives in another.

Clarus CFO ships a ROI dashboard at /cfodashboard/roi that runs the same classification on your portfolio. Each subscription gets tagged to one of the six categories at upload (or via a single review pass if uploaded earlier without tags). The dashboard then shows:

• The per-band spend total and percentage of portfolio.
• The blended ROI estimate (configurable per band; defaults from industry benchmarks).
• Per-team rollup color-coded green / amber / rose by ROI band.
• Vendor-level drill-through with the trailing-quarter spend trend.

The same tagging surfaces in the recommendations engine: a shelfware seat in a Direct-band tool ranks higher than the same shelfware in an Operating-band tool, because the dollar there is buying outcomes, not optionality.

For a portfolio of 50 to 200 line items, a single afternoon classification pass is enough. The first pass is the hard one; after that, new items get tagged at upload and the worksheet stays current automatically.

1. Export your AP system's last twelve months of software spend into a spreadsheet.
2. Add a Category column. Use the six categories from this article.
3. Walk every line. For ambiguous lines, default to the band one level lower than your gut says.
4. Sum spend per category and per band. Compare against the healthy-portfolio bands above.
5. Identify the three biggest mis-classifications: tools where the band you assigned is lower than what the team would say. Those are usually the right targets for renewal-time right-sizing.
