Controlling SaaS Spend Growth: The Quarterly Analysis Every FP&A Team Should Run
SaaS spend grows 15%+ per year without anyone really deciding it. Claude identifies in one prompt which tools doubled in cost and which are no longer being used.
The Problem
SaaS is the fastest-growing spend category in tech companies — and often the least monitored. It grows through three discrete mechanisms: seat creep when teams scale without optimising licences, annual price increases that vendors apply automatically, and shadow IT where tools are subscribed to locally without central approval.
The result is predictable: each quarter, the SaaS bill is a little higher. Nobody consciously decided it. The individual increases are too small to trigger an alert (Figma goes from €1,200 to €1,440, a mere €240 difference), but cumulated across 50 tools, they represent tens of thousands of euros in annual drift.
Yet the quarterly SaaS spend review is rarely done. It requires isolating the SaaS category from exports, finding functional duplicates, identifying tools that are no longer being invoiced (and therefore perhaps no longer used, or cancelled without telling Finance). It is an hour of manual work that few FP&A analysts find time to do systematically.
What the Spendesk MCP Changes with Claude
With the Spendesk MCP, SaaS analysis becomes a 30-second question. Claude aggregates data by category, calculates quarterly variations, and automatically flags anomalies — sharp increases, potential duplicates, ghost subscriptions.
SaaS Analysis — Q1 2026 vs Q2 2026
| Tool | Q1 2026 | Q2 2026 | Change | Growth |
|---|---|---|---|---|
| Salesforce | €18,400 | €27,600 | +€9,200 | +50.0% 🔴 |
| AWS | €42,100 | €58,300 | +€16,200 | +38.5% 🔴 |

| TOTAL SaaS | €97,500 | €127,700 | +€30,200 | +31.0% |
Would you like me to break down individual Salesforce invoices in Q2 to understand the source of that 50% increase?
Going Further: 2 Additional Use Cases
Identify Functional SaaS Duplicates
Functional duplicates — two tools doing the same thing — are common in fast-growing companies. Teams adopt solutions locally without central coordination.
Based on active suppliers and their declared categories, I identified 4 areas of potential duplication:
Video conferencing:
Project management / collaboration:
Email marketing:
Application monitoring:
Would you like me to prepare a summary of these duplicates for the next SaaS review with IT leadership?
SaaS Subscriptions With No Recent Invoice
Subscriptions that have not generated an invoice in more than 90 days may indicate an undocumented cancellation, a billing cycle change, or a ghost tool that is still active but no longer used.
I cross-referenced active SaaS suppliers against invoices received in the last 90 days (10/04/2026–09/07/2026).
5 SaaS suppliers with no invoice in the past 90 days:
| Supplier | Last Invoice | Days Without Invoice | Last Payment |
|---|---|---|---|
| Hotjar | 28/02/2026 | 131 days | €420 |
| Segment (Twilio) | 15/03/2026 | 116 days | €1,200 |
| Typeform | 02/04/2026 | 98 days | €290 |
| Loom | 05/04/2026 | 95 days | €340 |
| Mixpanel | 08/04/2026 | 92 days | €780 |
Would you like me to identify who on the team submitted the last invoice for each of these tools?
Key Takeaways
- SaaS spend grows structurally through seat creep, automatic price increases, and shadow IT — a quarterly review is essential.
spendesk_analyze_spendenables supplier-by-supplier quarter comparison in a single question, without any export.- Functional duplicates typically represent €20,000–€30,000/year in easily identified savings.
- A subscription without an invoice for 90 days warrants investigation — undocumented cancellation or billing cycle change.
- Combining growth analysis + duplicate detection + ghost subscription audit in a single quarterly review maximises the ROI of the exercise.
