Why Agencies Need This

  • Scrambling in January to compile full-year payment records for 1099 filings
  • Missing W-9 forms from creators that delay tax filings and trigger penalties
  • No visibility into which international creators require W-8BEN forms
  • Manual calculation of withholding tax on international creator payments
Platform note: Substack MRR is the most predictable income stream in the creator economy. Churn is the primary risk metric — ORACLE should flag when monthly churn rate exceeds 3% as an early warning. Paid conversion rate (free-to-paid) is the growth lever.
