- 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
what you lose
- Proprietary continuous Buy Box win-rate ML models
- Pre-built AWS SQS real-time SP-API notification pipeline infrastructure
- Automated multi-channel price syncing across Amazon, eBay, and Walmart simultaneously
- Fail-safe protection algorithms against race-to-the-bottom price spiraling
- Historical Buy Box change logs and competitor behavior analytics
