Automated enterprise advertising: compliance, audit trails, and scale
An enterprise advertising team running $2M/month in paid media has requirements that most automation tools were not built for. The approval chain involves more than one person. The audit log is not optional. And a model with unchecked write access to the account is a compliance incident waiting to be filed.
Why enterprise automation fails differently
SMB automation fails when a script runs out of budget or a rule fires on bad data. Enterprise automation fails in procurement reviews, compliance audits, and security assessments. The questions are different: who approved that change? Can you produce an immutable log? What happens if an AI model is compromised?
Most automation tools were designed to answer the first set of questions, not the second. SpendSignoff was designed with the second set as a first-class requirement.
The audit trail architecture
Every action taken through SpendSignoff writes a KMS-signed entry to an append-only audit log. The entry records: the draft ID, the action type, the affected entity, the before and after state, the approver's user ID and session ID, the timestamp, and the platform API response.
KMS-signed means the entry cannot be altered after the fact without the signature becoming invalid. Append-only means entries cannot be deleted without deleting the table. For enterprise compliance teams, this is the tamper-evident record they require for SOC 2 and internal governance audits.
Audit log entry (simplified)
{
"log_id": "alog_01HY...",
"draft_id": "drft_01HX...",
"action": "update_campaign_budget",
"approver_user_id": "user_clerk_...",
"approved_at": "2026-02-20T14:23:01Z",
"before": { "daily_budget_usd": 5000 },
"after": { "daily_budget_usd": 6500 },
"platform_response_code": 200,
"kms_signature": "eyJhb..."
}Multi-role approval chains
Enterprise advertising operations often require multiple approvers for large changes — a team lead reviews the draft, a budget owner approves the spend impact. SpendSignoff's role model in V1 supports owner and member roles per organization. Multi-stage approval (propose → team-lead review → budget-owner approve) is on the V2 roadmap.
In V1, the pattern is: the AI proposes, a human with owner-level access approves. For teams that need a second sign-off, the workflow is to share the draft URL with the second approver before confirming.
No model has approve authority at any tier
mcp.approve scope is not issued to models. Each approval stage requires a human session.Token vaulting and security posture
OAuth tokens for ad platform connections are vaulted with application-level KMS envelope encryption. The model never receives a token. It calls SpendSignoff tools, which call the platform APIs using vaulted tokens server-side. If the model session is compromised, the attacker gets the ability to call mcp.read and mcp.draft — not the raw tokens, and not mcp.approve.
Compliance checklist for enterprise evaluation
- KMS-signed append-only audit log — available in V1.
- Role-based access control (owner / member) — available in V1.
- OAuth token vaulting, never returned to model — available in V1.
- No model approve scope — available in V1.
- Multi-stage approval chain — V2 roadmap.
- SOC 2 Type II report — planned for post-GA.
- SCIM / enterprise SSO — V2 roadmap.
FAQ
- Can the audit log be exported to a SIEM?
- Yes. The audit log exports to Datadog and supports webhook delivery to any SIEM that accepts JSON. The format is documented in the API reference.
- What happens to data when we offboard?
- Organization data deletion follows the retention policy configured for the account. On offboard, all tokens are revoked and organization data is queued for deletion per the retention schedule, with a 30-day grace period for export.
- Does SpendSignoff support IP allowlisting for enterprise accounts?
- V1 does not include IP allowlisting. It is on the enterprise V2 roadmap. GCP Cloud Run's fixed IP ranges are available for firewall rules in the interim.
