Competitors and resellers change price, promo, and stock conditions faster than most teams can monitor manually.
Most monitoring tools show raw page diffs. MarginSonar focuses on commercially meaningful signals and why they matter.
See every competitor's price, promo, and stock status in one place. Filter by brand, channel, or signal type. Cross-brand category patterns surface trends no manual check would catch. Flag signals for policy review directly from the dashboard.
Add your SKU list and get AI-recommended competitor matches with confidence scores. Review, accept, or correct each pair — then see side-by-side pricing on your dashboard. Matched pairs feed directly into evidence packets for policy review.
Your DTC price, active promotions, and position vs the category average — front and center. Track sellers in a centralized ledger and review reseller activity against your MAP or channel policy.
Pricing, promos, stock status, and cross-brand patterns — all in one view. Filter by brand, channel, or signal type. Click into any brand for price history and event detail.

MarginSonar monitors publicly accessible pages across 11 channels daily. Every price, promo, and reseller signal is captured with timestamped evidence — no logins, no scraping behind access controls.
Captured signals are compared against your MAP or reseller policy. The platform flags which listings may be out of compliance and builds evidence packets your team can review before any action is taken.
Signals that warrant action are routed to the right person on your team — with evidence, seller context from the ledger, and draft notices ready for human approval before they are sent.
Every week, a short executive summary shows the biggest signals, policy review outcomes, disclosed blockers, and suggested next actions — giving your team a clear record of what was reviewed and what was approved.
Four examples from supplement brands reviewed in March 2026. Clean surfaces shown as clean, challenge-gated surfaces called out explicitly.
Public DTC monitoring on 2026-03-21 detected an active promo environment on the Garden of Life main storefront, plus clean probiotics category pricing across the Dr. Formulated line — useful intel for any brand watching this category.

Public monitoring found an active site-wide DTC promo coupon, a Walmart third-party reseller listing 24.5% below list price, and a Walgreens clearance markdown of 45% on a core SKU — three separate channel signals on a single brand in one sweep.
