Can I analyze performance by customer, channel, or cost code?

Yes. Apply filters and cost codes to attribute spend and volume to the right projects or channels. That visibility helps you evaluate promotions, catalog changes, and fulfillment locations with clear, defensible numbers.

Do these reports support real time decision making?

Reports can be generated on demand so you always have the latest available information after label creation. That up-to-date view supports real time style decisions during daily standups or carrier cut-off meetings.

How do I use the data with my BI or machine learning tools?

Export to CSV and drop it into spreadsheets, BI dashboards, or data pipelines. Many teams join shipping data analytics with order and inventory data to model transit times, forecast carrier capacity, or test the impact of new fulfillment nodes which are powerful ways to leverage shipping for growth.

What if leadership wants a quick summary?

Toggle between counts and Amount Paid to present either volume or spend. Print or export a concise summary for a board deck, or share a deeper CSV when stakeholders want to drill into shipping operations at the line-item level.
