The DPP Buying Guide: A Vendor-Neutral Evaluation Framework

This guide is built for three archetypes who together drive every serious DPP procurement decision. The Procurement Lead owns commercials, contract risk, vendor financial stability, and total cost of ownership. The Compliance Officer owns regulatory coverage, audit readiness, and the legal traceability of every data point inside the passport. The Head of Sustainability owns the data model, supplier engagement, and how the passport story is told to customers and investors. If you are any one of these three, the thirty questions below should map cleanly to your concerns. If you are running the evaluation alone, use this guide to build a cross-functional scoring committee — the worst DPP procurement decisions are the ones made by a single function in isolation.

Score every shortlisted vendor on each of the thirty questions below using a 0-3 scale (0 = not supported, 1 = roadmap, 2 = supported with limits, 3 = production-grade). Multiply each score by the importance weight you assign internally. The vendor with the highest weighted score is your candidate — but only if they pass every red-flag question (marked with an asterisk).

Build a matrix with three vendor columns (Vendor A, Vendor B, Vendor C) and the following row groups. Score each row 0-3 and sum by group. Reject any vendor that fails a red-flag row regardless of total score.

Use the following sections in your Request for Proposal. Each section maps directly to one of the 30 questions above and gives the vendor a clear, scorable place to answer.

Headline list price is rarely the largest line item in a DPP TCO model. Build your TCO over five years with the following ten components, then sensitivity-test it against 2x and 5x volume.

Once you have weighted scores and a TCO model, run a final risk-adjusted decision matrix. For each vendor, multiply the weighted score by a risk factor (1.0 = low risk, 0.7 = medium risk, 0.4 = high risk) using the four risk dimensions below. The vendor with the highest risk-adjusted score wins. The dimensions are: regulatory risk (will the vendor keep up with new delegated acts), integration risk (will connectors actually deliver inside your ERP landscape), commercial risk (vendor financial stability, pricing surprises), and exit risk (how painful is leaving). A vendor that scores 95 with a 0.4 high-risk multiplier (38) loses to a vendor that scores 75 with a 1.0 low-risk multiplier (75). This is the single discipline that separates buyers who land on a multi-year DPP success story from buyers who quietly re-bid the platform 18 months later.

We sell DPPs, so take this with appropriate scepticism — but we genuinely believe the buyer who runs this framework rigorously will rarely pick the wrong vendor, even if that vendor is not us. Three closing rules. First, never let one function pick the platform alone — always assemble procurement, compliance, and sustainability leads in the same room. Second, always insist on a paid pilot against your real ERP and a real supplier before a full contract. Third, write the exit clause first. If a vendor will not give you a clean exit on day one, they will not give you a clean exit on day 1095.
