Monitor official sources
We track reviewed carrier pricing, surcharge and service pages. A page change creates a review task and never publishes itself.
Carrier changes become decisions your team can act on.
CarrierShock connects official notices to the shipping details that determine your real exposure.
Describe your shipping mix
Use guided onboarding or securely upload a CSV, spreadsheet or rate-card PDF. Extracted details stay in draft until you confirm them.
Calculate your exposure
Deterministic rules match the notice to your carriers, routes, products, weights and eligible volume.
Review the evidence
Every result retains its official source, effective date, assumptions, missing information and confidence level.
What CarrierShock calculates
CarrierShock estimates the incremental shipping cost created by a published carrier change. It does not replace the carrier agreement or invoice. When a source does not contain enough information for a reliable calculation, the update remains information-only.
See the cost before it reaches the invoice.
