the day-to-day

Do any of these sound familiar?

  • — "Another deadline missed."

    A fine for a form you knew was due.

  • — "How much would we pay if we raise Marta to €2,000?"

    "I'll look into it and get back to you in a few days."

  • — "My advisor takes 48 hours to reply."

    And you needed it yesterday.

what you gain

Get your time back, sleep better.

  • "Which taxes are due this month?"
  • "How much would I pay if I raise Marta's salary?"
  • "Am I current with Social Security?"
