Custom scope to take KDP Sales Auditor from MVP shell to operating business.

• ▸Production backend deployment on cloud infrastructure with monitoring and alerting
• ▸Stripe billing across free tier and three monthly pricing tiers
• ▸Robust CSV import with error handling, retries, and failure notifications
• ▸Email signup sequences and customer onboarding flows for trial conversion
• ▸API documentation, customer help center, and operational runbooks
• ▸Security hardening including rate limiting and input validation
• ▸Usage analytics and customer success dashboard for retention tracking
• ▸30-day launch support and customer success handoff to operator

Why this could work.

The GTM has real leverage: free tier distributed in niche Facebook groups and Reddit feeds publishers already visit. It targets publishers with 10+ titles and tool budgets. Email sequences drive conversion to $19-29 monthly pricing tiers. At 15 percent conversion of discovered publishers, you hit $30k plus ARR. Publishers genuinely struggle tracking performance across multiple titles manually. Churn risk is real but acquisition is nearly free.

What you'd risk.

Amazon's most obvious next move is native multi-title analytics in the KDP dashboard, eliminating your core value prop overnight with zero warning. CSV export format changes break ingestion regularly since no public API exists. Your customer base is price-sensitive hobby publishers with high churn when experiments underperform. Low lifetime value and near-zero acquisition cost requirements compound the economics fragility. Year one projects negative take-home with 15 percent success probability.

Who this fits.

This suits an operator with existing relationships or credibility in indie publishing: a former KDP publisher, a writing coach with a student base, an indie publishing agency, or a SaaS founder already serving authors. Requires comfort with brittle data pipelines and publisher churn. Less ideal for cold-start founders without publishing industry connections.
