Obtain certified snowfall totals to resolve a billing dispute

Steps

1. When a billing or service dispute hinges on snowfall depth, request a certified/documented snowfall total for the exact date and location rather than relying on memory or a single station reading.
2. Use a commercial certified snowfall report service that compiles and quality-controls observations from multiple public and private sources into a report formatted for billing or legal use.
3. Request the report promptly after the storm, since providers pull from post-storm observation networks and older events can be harder to reconstruct precisely.
4. Cross-check the certified total against public NWS/CoCoRaHS data for the same period as a sanity check before relying on it in a dispute.
5. Attach the certified report to invoicing or claim documentation as an independent third-party record, distinct from the contractor's own service logs.
