The vendor looks good, but the plan risk is unclear.
Pricing tiers, enterprise gates, seat growth, add-ons, and usage limits can change the real cost of ownership.
Vendor due diligence
Know whether a software vendor is worth the risk before you commit.
EvidenceOps turns pricing pages, trust centers, help docs, DPAs, terms, claims, and unresolved risks into a short decision brief your team can review internally.
When it matters
Vendor research is easy to collect and hard to defend.
Most teams already have screenshots, links, opinions, and vendor promises. The missing layer is the weighted judgment that explains what actually decides the risk.
Security and compliance claims need source quality.
Trust-center claims only help when they connect to evidence such as SOC 2, DPA terms, subprocessors, SSO, audit logs, and retention.
The internal decision needs to survive review.
Finance, Operations, Legal, IT, and founders need a recommendation they can inspect rather than another feature list.
Evidence layer
What gets checked in a vendor due diligence review.
The review focuses on decision-critical evidence, not exhaustive browsing. Each relevant statement becomes a claim with source, confidence, impact, likelihood, contradictions, and follow-up need.
Pricing and TCO
Plan fit, enterprise gates, seat expansion, add-ons, renewal risk
Controls
SSO, SCIM, audit logs, admin controls, export, retention
Compliance
DPA, subprocessors, hosting region, SOC 2 / ISO signals, terms
Lock-in
Data portability, export quality, migration risk, process dependency
Contradictions
Conflicting docs, outdated help-center pages, missing public claims
Verification
Questions to ask vendor, tests to run, documents to request
Decision psychology
The output is designed to reduce internal hesitation.
The buyer is not paying for more information. They are paying for a defensible decision structure that makes the next move obvious.
A clear verdict
Go, No-Go, or conditional Go stated plainly, with the reason why.
Visible uncertainty
Unresolved questions are not hidden. They become a verification queue.
Evidence-backed language
Claims stay attached to sources so the decision can be explained in a meeting.
