Recipes

Leave no stone unturned. Each run on our own studio.

  • Google Calendar and Millstone

    Turn last week's calendar into time

    “Go through my calendar for last week, match each client call to its project in Millstone, and tell me which have no time logged.”

    When we ran it: Matched every work call to the right project, left the personal events out, and found one client call with no time against it.

  • Gmail and Millstone

    Check what you invoiced by email

    “Find the invoices I emailed this month and check each one against Millstone.”

    When we ran it: Found an invoice sent by email whose copy in Millstone was still an unnumbered draft, so the inbox and the books disagreed.

  • Gmail and Millstone

    Find who is missing from your contacts

    “Who has emailed me about client work this month who is not in Millstone yet?”

    When we ran it: Found a client's assistant writing in about a live project: named in a task, but with no contact record of their own.
