If your business runs on Google Sheets, a few hundred lines of Apps Script can do what would otherwise need a new app: build the weekly report, send the reminders, file the attachments, sync with your CRM.
What you get
A script or add-on installed in your own Google account, with comments in the code and a short guide to running and changing it.
Good fit when
The data already lives in Google Workspace and the team is happy working there.
