In the Shiptheory Reporting page, you may sometimes notice what seem to be inconsistencies in the amount of orders under "completed" in contrast to the actual amount of orders that have been completed in the month.
Or, perhaps, you've hit your monthly allowance, but the reporting page says you've not completed as many shipments.
The reason for this is because shipments displayed on the reporting page are only shipments that have also come into Shiptheory during the selected time period.
For example, if you selected to view all shipments booked in May; if an order had come into Shiptheory in April, but booked in and completed in May, it wouldn't show on the page.
If you're still having issues with consistencies and don't believe that this accounts for it, feel free to contact support.
