Vendor Due Diligence Questionnaire Completion Service
Enterprise buyers use DDQs to test whether a vendor’s security, privacy, operational and AI claims can survive scrutiny. ProcureDeal helps the vendor prepare responses from existing evidence, cite the source behind each material answer and flag questions that require confirmation.
Complete vendor DDQs without guessing
A vendor due-diligence questionnaire can combine security controls, privacy terms, subprocessors, incident management, business continuity, data retention, access management, SDLC practices, compliance evidence and AI governance in one document. The safest response process separates what your evidence proves from what still needs an owner.
Security evidence
Ground responses in current policies, control descriptions, audit material and approved security documentation supplied by your team.
Privacy & data handling
Surface questions that need privacy or legal confirmation rather than generating unsupported contractual or regulatory statements.
AI due diligence
Support emerging buyer questions about model providers, customer-data use, prompt/output retention, human oversight and AI governance.
DDQ, SIG, CAIQ or custom spreadsheet
Buyers use different questionnaires depending on industry and procurement process. ProcureDeal can support standard or custom reviews where the customer provides the source documentation needed to answer them. Dedicated pages are available for SIG questionnaire completion, CAIQ questionnaire completion and AI security questionnaire completion.

What ProcureDeal does not claim
The service is not a certification, audit attestation or legal opinion and does not guarantee buyer approval. AI-assisted drafts require customer review. If the supplied evidence cannot support a requested claim, the workflow is designed to expose that limitation rather than silently fill the gap.
Frequently asked questions
What is a vendor due diligence questionnaire?
It is a buyer-side assessment used to evaluate a prospective vendor’s security, privacy, operational, compliance and sometimes AI practices before or during procurement.
Can ProcureDeal complete a DDQ for a SaaS vendor?
ProcureDeal can prepare evidence-backed draft responses when the SaaS vendor supplies the questionnaire and relevant approved documentation.
Does the service support SIG and CAIQ?
Yes. ProcureDeal has dedicated workflows and pages for SIG, CAIQ, AI-CAIQ and custom vendor questionnaires.
What happens when a DDQ asks for something we cannot prove?
The item should remain a gap or require human confirmation. ProcureDeal is designed not to convert missing evidence into an unsupported claim.
