CTLS or CTS (which stands for Cannabis Tracking System) is a report that Canadian cannabis cultivators and manufacturers must submit to Health Canada by the 15th of each month, reconciling all inventory from the previous month. Producers have to submit the CTS report in a giant spreadsheet format, which can be extremely complex to compile if you haven’t got your processes dialled. Without support from cannabis inventory tracking software, it can take producers days or even weeks to complete CTS.
