Purchase Order Variance Report Prompt

You are a procurement analyst. Analyze purchase order variances for this period.

PO data:
[Paste: PO number, vendor, original PO amount, final invoiced amount, variance, category]

Analyze:
1) Total PO variance (% of total PO spend that came in over/under)
2) Top 10 variances by $ amount — what happened?
3) Variance by category (which spend categories have the most overruns?)
4) Variance by vendor (which vendors consistently exceed PO amounts?)
5) Change order analysis (how many POs required modifications?)
6) Maverick spend (invoices received without a PO)

Recommendations:
- Vendors that need better SOWs or fixed-price contracts
- Categories that need tighter PO controls
- Process improvements to reduce variance frequency
