Repricer

A repricer is software that automatically adjusts your product prices on Amazon in response to competitor price changes, Buy Box ownership shifts, and rules you configure. The motivation: at any meaningful catalog size, manual repricing is impossible — competitors change prices hundreds of times per day, the Buy Box rotates every few minutes, and any seller still typing prices into Seller Central is leaving money on the table.

Repricers come in three rough generations: (1) Match-the-lowest-price scripts (worse than nothing because they collapse the Buy Box for everyone), (2) Rule-based repricers with margin floors (acceptable for stable catalogs), (3) Strategic repricers that model Buy Box probability, factor in fulfillment channel, and protect margin against TACoS pressure (the only generation worth using on a serious business).

The most important repricer features to demand: hard margin floors at the database level (so the repricer literally CANNOT submit a price below the floor), anti-oscillation guards (to prevent narrow-band zig-zag pricing storms), velocity circuit breakers (to halt the repricer when submission rates spike unexpectedly), and a full audit trail per SKU. SellerVault has all four — see the Complete Amazon Repricing Guide for the full feature checklist.
