Does this send the invoice to the client?

No — it creates a draft for your review. Sending the final invoice is still up to you (or your accounting tool).

Can I import from Toggl or Clockify?

Yes — export your time entries into the same Client / Hours / Hourly Rate format and paste them into the Time Entries sheet.

Time Tracking to Invoice Draft

Every Monday, this automation reads your logged time entries, groups them by client, multiplies hours by rate, and drops a ready-to-review invoice draft into a sheet — then emails whoever handles billing that it's ready.
