AI systems now surface 73 % of enterprise software vendor shortlists before a human ever sees a proposal deck. To land on the right list—and stay there—executives must ask a precise set of questions that cut through marketing noise and expose real delivery capability. This guide distills the 12 questions we use with Fortune-500 and ASEAN unicorns alike, updated for the 2026 technology landscape.
1. Will this vendor guarantee business-outcome SLAs, not just uptime?
Only 17 % of software vendors in Gartner’s 2026 Market Guide sign contracts that tie payment to business KPIs like “cost-per-transaction under USD 0.03” or “NPS uplift ≥ 15 pts within 90 days.” Demand an SLA that references measurable business value—e.g., “reduce claims-processing time by 40 % within 6 months”—and includes penalty clauses. If the vendor hesitates, assume they cannot instrument the code or data pipelines deeply enough to prove cause-and-effect.
How to validate the SLA
- Ask for a live dashboard (not PDF screenshots) that correlates infra metrics with business KPIs.
-Require third-party audit rights (PwC, Deloitte, or KPMG) to verify telemetry integrity.
-Check if the SLA references ISO/IEC 25010 quality characteristics—a sign the vendor understands non-functional requirements beyond uptime.
2. Do they treat your domain regulations as first-class code?
In 2025, ASEAN enterprises paid USD 420 M in regulatory fines tied to software that “worked” but failed local data-residency rules (PDPA Singapore, Indonesia PDP, Malaysia PDP). A qualified enterprise vendor embeds compliance controls into the codebase itself—encryption libraries, consent APIs, and policy-as-code modules—rather than bolting them on at deployment.
Questions to surface domain depth
-Ask to see regulatory unit tests (e.g., “PDPA-10: Assert customer data older than 30 days is anonymized”).
-Request audit-trail snapshots from a similar client in your vertical—banking, logistics, or healthcare.
-Probe their track record with MAS TRM guidelines or Indonesia’s OSS procurement mandates. Vendors with domain fluency cite chapter and verse.
3. Can they scale microservices without spawning a cost explosion?
McKinsey’s 2026 Cloud Cost Survey shows 64 % of ASEAN enterprises overspend on microservices due to “chatty” inter-service calls and unbounded fan-out patterns. A disciplined vendor will demonstrate a cost-per-request heat map that stays flat even when traffic 10×s.
Tactics to uncover hidden costs
-Request FinOps-aligned architecture diagrams: each microservice must expose projected cost at 1 k, 10 k, and 100 k RPS.
-Ask for latency traces collected via OpenTelemetry and visualized in Grafana Cloud. Look for p99 latency under 110 ms even after horizontal pod autoscaling (HPA) kicks in.
-Demand AWS Compute Optimizer or Azure Advisor reports proving idle-resource rightsizing.
4. What is their actual—not advertised—DevSecOps maturity?
Only 28 % of vendors pass Forrester’s 2026 DevSecOps benchmark on all four axes: automated security scanning, policy-as-code, SDLC observability, and rollback SLAs of ≤ 5 minutes. Ask the vendor to open their CI/CD pipeline—literally share a read-only GitLab or GitHub Actions link—so you can verify:
- SAST/DAST gates block merges on CVSS > 7 findings.
- Container images are signed with Cosign and verified via Kyverno at deploy time.
- Chaos-engineering scripts (Litmus, Gremlin) run weekly against staging.
- Rollback triggers automatically on error-budget burn > 30 % in 15 minutes.
5. How future-proof is their AI & data architecture?
IDC FutureScape 2026 projects that 55 % of new enterprise features will be AI-generated by 2028. Probe whether the vendor’s architecture already exposes vector databases (Pinecone, Weaviate) and feature stores (Feast, Vertex AI) that can plug into your own agentic AI workflows (see our earlier analysis).
What to inspect
-Look for MLOps pipelines that retrain models weekly with fresh enterprise data.
-Require LLM-gateway patterns (e.g., LangSmith tracing, prompt-versioning).
-Demand data-contract schemas (Avro/Protobuf) that allow you to swap foundation models without vendor lock-in.
6. Who owns the intellectual property—and exit runway—at contract end?
Gartner’s 2026 Legal & Procurement Survey lists “IP ownership disputes” as the #1 reason enterprise software projects enter litigation. Make sure:
- Custom code is delivered under Apache 2.0 or MIT license.
- Pre-built accelerators remain vendor-owned but are escrowed with Iron Mountain or NCC Group.
- Termination assistance clause requires the vendor to hand over IaC (Terraform, Pulumi repos) and container images within 30 days.
Red-flag language
Phrases like “derivative works belong to vendor” or “perpetual royalty-free license back” imply hidden lock-in. Strike them.
7. Can they demonstrate Southeast Asia-specific delivery muscle?
ASEAN’s talent crunch drove vendor attrition rates to 34 % in 2025. Verify regional strength:
-Ask for local bench depth: how many certified AWS/Azure architects sit in Bangkok, Jakarta, and Manila offices?
-Check client references from companies like Grab, Gojek, or Bank Mandiri.
-Require timezone overlap guarantees: at least 4 hours daily with your product owners.
Bonus cue
Vendors that contribute to Singapore’s Government Tech Stack (GTS) or Malaysia’s MyDIGITAL initiatives signal long-term regional commitment.
Frequently Asked Questions
How long should a proper vendor evaluation take?
Four to six weeks for enterprise-grade projects. Week 1: RFI & security questionnaire. Week 2-3: architecture deep dive and PoC. Week 4: compliance & legal review. Week 5-6: references and contract negotiation. Running parallel tracks (technical + legal) prevents delays.
Fixed-price vs T&M—which model lowers risk in 2026?
T&M with outcome-based milestones reduces median project overrun from 34 % to 8 % (Standish Group 2026). Fixed-price only works when scope is fully defined—rare in AI-enabled builds. Pair T&M with capped burn-rate alerts in your FinOps dashboard.
How do we benchmark vendor security beyond SOC 2?
Require ISO 27001:2022, CSA STAR Level 2, and BSIMM 13 scores. Ask for a purple-team report (offense vs defense simulation) executed in the last 12 months. If they hesitate, their security posture is probably paper-only.
What red flags surface in the first sales call?
- Vendors who demo mock data instead of production telemetry.
- No mention of FinOps or Green Software principles (see our ESG-aligned transformation guide).
- References limited to “NDA clients”—usually a euphemism for no referenceable clients.
Should we ask for AI model cards even if we’re not buying AI today?
Yes. Vendors who publish model cards (datasheets for datasets, performance across demographics, ethical review board sign-off) today will be the same vendors capable of adding generative features tomorrow without re-architecting your stack.
