Krenz & Hannan Cuts Entry Prep from an Hour to Minutes

Before Altana

Krenz & Hannan is a family-run freight forwarder, indirect air carrier, and customs brokerage in Greendale, Wisconsin. Third-party back-office support still left accuracy gaps, communication friction, and a need for close broker oversight. Entries began requiring multiple tariff codes per line item, large shipments ran 50 to 200+ lines, and regulatory changes were constant. Active time reached 15 minutes to an hour or more per entry, while internal audit scope grew from a small subset of entries to every one.

With Altana

The Altana Customs Declaration Agent now automates document extraction and entry preparation, while Krenz & Hannan's brokers keep control of review and submission. SOP Studio captures importer-specific rules and coaches the system on exceptions, document quirks, and classification nuance. The Product Catalog builds from existing parts data so repeat shipments process consistently, and NetCHB integration moves data into the brokerage's existing ABI workflow.
Active processing time fell 80%, from 15 to 60+ minutes to 5 to 10 per entry. Accuracy is 97%+ once the system is coached, with errors near zero, and the team now audits 100% of entries internally without added staff.
“The processing time goes from significant to almost negligible.”
