The pre-sourcing checklist that catches costly mistakes
Most first-time sellers skip validation and end up sitting on inventory that barely breaks even. Run every product through these six checks before you wire a supplier.
Used by 2,400+ sellers before their first order
Six checks, one pass
Each check maps to a section of the checklist with specific thresholds, formulas, and red flags to watch for.
Validate Demand
Confirm monthly sales volume, BSR trends, and search demand before committing to a product.
Analyze Competition
Evaluate the number of direct sellers, listing quality, and review counts to find real entry points.
Calculate Margins
Run the numbers on Amazon fees, shipping, PPC, and landed cost to ensure 25%+ net margin.
Check Seasonality
Verify sales are stable across 9+ months so you are not stuck with dead inventory after a spike.
Plan Differentiation
Identify bundling, branding, or feature improvements that separate you from commodity listings.
Vet Suppliers
Use the included outreach templates to contact manufacturers, request samples, and compare quotes.
