Log work in Harvest from a Slack update

Share a clear work update in Slack and let Notis record it in Harvest, so billable hours do not have to wait for a separate admin session.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Create Time Entry

Tool to create a new time entry. use when logging hours for a project by specifying start/end times or duration.

Why this helps

Reconstructing work at the end of a busy day can be difficult, and small billable tasks are easy to forget.

  • Capture work while the details are fresh.
  • Reduce end-of-week time reconstruction.
  • Get a run report when the project, task, or duration is unclear.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Harvest to Notis once in the portal.
  • 2Create an automation in the portal, or ask Notis in plain language for an automation that records qualifying Slack work updates in Harvest.
  • 3State in the instruction to create a time entry only when the message supplies enough detail, and to report missing details instead of guessing.
  • 4Pick the Slack channel message trigger and choose a channel for run reports.
  • 5Test with one real work update that includes the project, task, date, and duration.

Questions about this workflow

Will every message in the channel become a time entry?

The instruction can tell Notis to act only on messages that clearly describe completed work and include enough logging details.

What happens if I leave out the duration?

Tell Notis to report the missing detail instead of creating an inaccurate entry.
