Finance leads and analysts
You're reviewing timesheet entries and expenses in Harvest but your financial reports only update when someone manually exports data, so the cost calculations you're reviewing are always a few hours behind — automating both apps means every timesheet and expense lands in your tracking sheets instantly and your data stays current.
Project managers
You need to act fast when project tasks or timesheets change, but you find out too late because notifications stay trapped in isolated tools — connecting these apps means every update posts straight to your team channel and you can coordinate responses immediately.
🤝
Account managers
You answer to clients who want to see steady progress on their billable hours, but pulling status updates requires manual cross-referencing across platforms — this integration means every invoice and project milestone is logged automatically and client reporting takes minutes instead of hours.
📊
Operations coordinators
The volume of daily timesheet entries and project tasks is too high for anyone to keep up by hand, leading to missed logs and scheduling bottlenecks — integrating these apps means high-volume data flows smoothly between your time tracker and chat workspace without manual effort.
👥
Team leads and supervisors
You depend on team members logging billable hours upstream before you can review project progress and assign the next phase of work — automating both apps means team notifications fire instantly upon submission so your handoffs happen without friction.
🗂️
Project coordinators
You need a reliable history of project creation and task additions, but keep finding gaps where manual records were forgotten — this integration means every record is captured systematically and your historical project logs remain complete.
