Everything a serious Amazon business runs on

Winning the Buy Box on price alone is a race to zero margin. The SellerOS repricer computes a net-margin floor from your real itemized costs, predicts your Buy Box win probability, and reacts to competitor moves the moment Amazon publishes them.

• Four strategies per listing: win Buy Box, maximize profit, match lowest, fixed
• Aggressiveness dial — from token-cent undercuts to volume pushes
• Net-margin floor honoring Amazon's $0.30 referral minimum and VAT
• Buy Box win-probability model scoring every suggested price
• Price-war detection that holds the floor instead of chasing down
• Suppressed-Buy-Box recovery pricing
• Event-driven repricing on ANY_OFFER_CHANGED notifications
• Multichannel replication: mirror Amazon prices to Shopify, eBay, Walmart rules

Ad spend is most sellers' second-biggest cost after COGS — and the easiest one to waste. SellerOS pulls every keyword toward your target ACoS and shuts off the spend that never converts.

• AI bid optimizer: per-keyword raise / lower / hold with reasoning
• Account-level target ACoS with rate-limited bid changes
• Search-term analyzer: negate, harvest, reduce-bid, keep
• Break-even ACoS and maximum-bid calculators
• TACoS tracking and ad budget pacing with overspend warnings
• Campaign manager for Sponsored Products, Brands and Display

Before you spend a dollar on inventory or ads, know the demand, the competition, and the keywords that move rank.

• Product & niche research with opportunity scoring
• Keyword research, volume estimates and reverse-ASIN lookups
• Keyword gap analysis against any competitor
• Daily rank tracking with index checking
• Sales estimator: BSR → monthly-units modeling by category
• A/B split-test significance calculator for listing changes

Your listing is your storefront. SellerOS grades it against Amazon's own best practices and helps you fix what's costing you clicks.

• Keyword density and stuffing detection
• AI Listing Optimizer (Claude-powered) for titles, bullets and descriptions

• Stockout cost and aged-inventory decision engines
• FBA shipment planner with Amazon's carton limits
• ABC analysis and inventory ROI ranking
