Vertex AI Notes for B2B SaaS: Separate Sales FAQ from Support History

In B2B SaaS, every document starts to look like useful AI context: sales FAQs, help center pages, support tickets, deal notes, roadmap comments, and Slack answers. If customer names, contract terms, incidents, and unreleased features enter the same index, the FAQ becomes a data leak path.

This article uses Claude Code to draft a Vertex AI integration note before implementation. The goal is to separate sales FAQ from support history, reduce pre-sales uncertainty, and keep customer data away from broad AI context.

What This Article Covers

• Keep sales FAQ, help content, support history, deal notes, and roadmap data in separate buckets.

• Use Vertex AI RAG, Grounding, Agent Search, and safety filters after data boundaries are clear.

• Claude Code drafts classification tables, test questions, prompts, and operations notes.

• Humans decide customer names, contracts, incidents, unpublished features, legal wording, and pricing answers.

• Send implementation-heavy readers to training because every SaaS has different data rules.

Where SaaS AI FAQ Projects Go Wrong

Start with four buckets: public sales FAQ, support FAQ, internal review, and do-not-send-to-AI. Vertex AI RAG, Grounding, Agent Search data stores, and safety filters help with grounded answers, but they do not decide which SaaS data is safe for a public or pre-sales answer.

Workflow: Split Data Before Vertex AI

Start with four buckets: public sales FAQ, support FAQ, internal review, and do-not-send-to-AI. Vertex AI RAG, Grounding, Agent Search data stores, and safety filters help with grounded answers, but they do not decide which SaaS data is safe for a public or pre-sales answer.

| Source | AI use | Human review |

| --- | --- | --- |

| Sales FAQ | public features, public pricing, buying questions | legal wording and pricing examples |

| Help center | operations, settings, roles, errors | old UI and deprecated features |

| Support history | anonymized patterns and frequent errors | customer names, contracts, incidents |

| Deal notes | usually no direct AI use | budget, discount, roadmap, buyer name |

What Claude Code Does and What Humans Decide

Start with four buckets: public sales FAQ, support FAQ, internal review, and do-not-send-to-AI. Vertex AI RAG, Grounding, Agent Search data stores, and safety filters help with grounded answers, but they do not decide which SaaS data is safe for a public or pre-sales answer.

3 Use Cases

Use case 1: Split sales FAQ and support history

• Input: public FAQ, help articles, support CSV columns, ticket tags, pre-sales questions.

• Output: four-bucket table: sales FAQ, support FAQ, internal review, do-not-send-to-AI.

• Human review: check customer names, contracts, incident history, unpublished features, and special pricing.

Use case 2: Build test questions before Vertex AI

• Input: buyer persona, pricing page, help articles, prohibited answers, escalation rules.

• Output: allowed questions, handoff questions, and questions requiring source links.

• Human review: decide boundaries for pricing, contracts, security, incidents, cancellation, and custom requests.

Use case 3: Create operations notes for wrong answers

• Input: wrong answers, ticket logs, support corrections, FAQ update history.

• Output: issue class, data source to fix, retest question, and approver.

• Human review: legal wording, refund terms, incident explanations, customer impact, and release timing.

Copy-Paste Prompt

Create a Vertex AI integration note for a B2B SaaS. Goal: separate sales FAQ from support history and avoid sending customer data into broad AI context. Create four buckets, twenty test questions, handoff rules, source-link rules, and operations notes. Do not paste real customer values. Main CTA: /training/.

Working Check Code

const faqCandidates = [{ source: 'support_history', title: 'Client incident response', bucket: 'sales_faq', fields: ['customerName', 'incidentId', 'contractNote'] }];

const sensitiveHints = [/customer/i, /contract/i, /incident/i, /discount/i, /account/i];

const findings = faqCandidates.flatMap((item) => {

  const sensitiveFields = item.fields.filter((field) => sensitiveHints.some((pattern) => pattern.test(field)));

  return item.bucket === 'sales_faq' && sensitiveFields.length ? [{ title: item.title, issue: sensitiveFields.join(', ') }] : [];

});

console.table(findings);

if (findings.length) process.exitCode = 1;

Pitfall: RAG Makes the Wrong Data Sound Correct

Start with four buckets: public sales FAQ, support FAQ, internal review, and do-not-send-to-AI. Vertex AI RAG, Grounding, Agent Search data stores, and safety filters help with grounded answers, but they do not decide which SaaS data is safe for a public or pre-sales answer.

Cause: RAG brings answers closer to the indexed data. If the indexed data is wrong for sales use, the answer becomes confidently wrong or unsafe. Fix: split data before ingestion, use anonymized support patterns, and keep contracts, incidents, and roadmap notes out of public FAQ context.

FAQ

Q. What should come first? A. A data classification table, not a model setting.

Q. Should all support history be removed? A. No. Patterns and tags can help, but customer-specific details need separation.

Q. Why training? A. Vertex AI, Agent Search, RAG, data boundaries, and security review differ by SaaS.

What I Actually Checked

This article checks frontmatter, official links, three use cases, input-output-human review labels, code fences, and the /training/ CTA. The JavaScript sample detects customer, contract, and incident fields mixed into sales FAQ candidates.
