Questions

Which tools can it work in?

Your invoicing or accounting app, your email and wherever finished jobs are recorded today, like a spreadsheet or a job tool. Your plan names every tool it touches.

Every agent is custom. Tell us how the work really runs in the quiz, and your written plan follows it.
