Spend analysis report: what to include and what to cut

Published 3 September 2026 · 6 min read

A spend analysis report is the document that turns classified data into decisions. Most are too long and say too little: forty slides of pie charts and no recommendation anyone can act on. Here is what actually earns its place.

What to include in a spend analysis report

One number on the first page. Total addressable spend, the period it covers, and the exclusions. Everything after it is a breakdown of that figure, so if it is wrong or undefined the rest is noise.
Spend by Level 1 category, with supplier counts beside the values. Spend alone tells you where the money is; spend plus supplier count tells you where the fragmentation is, which is where the savings are.
Top 20 suppliers with share of total. This is the concentration picture and takes ten seconds to read.
The tail, quantified. How much spend sits with suppliers below your threshold, and how many suppliers that is.
Three to five recommendations, each with an estimated value, an owner, and a first step.
A data-quality note. What was excluded, what was unclassified, and what you are not confident about.

What to leave out

Month-by-month trend charts unless something changed. Twelve bars of roughly equal height is not a finding.
Category breakdowns below Level 2 in the main body. Put them in an appendix; nobody reads a 400-row leaf table in a meeting.
Percentages without absolutes. “Facilities is up 12%” means nothing without the base.
Methodology at the front. Put it at the back. The audience wants the answer first.

The data-quality note is not optional

Every spend analysis has gaps — unclassified rows, intercompany charges, a subsidiary whose data arrived late. Say so, in one short section, with numbers.

This is self-interest, not modesty. The fastest way to lose an audience is for a sceptical CFO to find a gap you did not mention. If you named it first, it is a caveat. If they find it, your whole report is in question.

Recommendations need an owner and a number

“Consider consolidating cleaning suppliers” will not happen. “Run an RFQ across the 14 cleaning-chemical suppliers, approximately GBP 180k addressable, 6–14% typical saving, owned by category management, first step is a spec review in March” might.

If you cannot name an owner, it is an observation, not a recommendation. Move it to the appendix.

How long it should be

Ten to fifteen slides, or five to eight pages. If the analysis is good, brevity is achievable; length is usually a symptom of not having decided what matters.
