our call
Start with Informed.co — highest vibe code, weakest moat.

- Min/Max price guardrails based on COGS and target ROI
- Scheduled price adjustments and off-peak price resetting
- Competitor exclude/include lists based on seller rating and fulfillment method
- Basic profit margin and fee calculations per SKU
