Growth teams rarely waste budget because one dashboard is obviously broken. The costly failure happens when Meta Ads, Google Performance Max, TikTok, LinkedIn, and GA4 each tell a plausible story that diverges by 30–45% from settled Stripe cash.

The Two-Sided Attribution Trap

1. Phantom ROAS (View-Through Overlap & Refund Skew)

Ad platforms default to attribution windows that maximize claimed conversions. A buyer who scrolls past a retargeting ad on Instagram, clicks a Google Brand Search ad, and later requests a Stripe refund 72 hours after purchase remains counted as a full-price conversion inside both ad platforms.

When media buyers scale daily budgets based on gross pre-refund platform ROAS, they systematically over-allocate capital to high-refund cohorts and cannibalized brand traffic.

2. Unattributed Spend & Governance Drift

At monthly finance close, the CFO reconciles total paid media spend against net bank deposits in Stripe and closed-won contracts in HubSpot. Without a deterministic transaction-level tie-out, Marketing and Finance spend days debating spreadsheet exports while unprofitable campaigns continue burning budget.

How Skewix Enforces Closed-Loop Governance

1. Real-Time Refund & Dispute Deduction: Skewix ingests charge.succeeded, charge.refunded, and charge.dispute.created webhooks from Stripe alongside HubSpot closedwon deals to compute True Net Cash ROAS per campaign.
2. 1-Click Campaign Budget Guardrails: When a campaign’s verified Stripe Net ROAS drops below your break-even threshold due to view-through inflation or refund drift, operators can pause the campaign or cap its daily budget by 25–50% directly via the Meta and Google Ads APIs.
3. Cryptographic CFO Audit Packets: Export signed PDF and CSV reconciliation packets containing campaign spend, Stripe charge IDs, refund adjustments, and CAPI fbtrace_id recovery receipts.
