Export the records of any period as PDF or CSV for an inspection (Pro).

The client's name and address, the service date and start time, and the applicator's name are always recorded. The app uses the 01-026 CMR ch. 50 §1 template. It doesn't check items the app doesn't record (for example active ingredients or equipment); those remain your responsibility.
