As a technician you can always copy a previously submitted report, edit any entries you want and resubmit the report, but if you have an office staff that reviews and then sends out the final report this may become cumbersome at times. Use Adobe Acrobat Pro in the office to bypass this bottleneck.
At The Chimney Doctor their techs submit reports throughout the week. They are automatically emailed to their office staff who reviews the reports prior to sending them to the customer. During this review if there are major substantive changes that need to be made they kick it back to the technician and let them know they need to update their report. If only minor changes are needed then they use Adobe Acrobat Pro to edit the pdf and correct minor formatting or spelling issues prior to sending it out.
Here is a video walkthrough of that process.
