Documents connect in context: a quote or estimate can precede accepted work—see the quote-to-invoice workflow. A timesheet supports billable hours, while a work order records a job; the timesheet-to-invoice guide and client billing workflow explain the handoff to billing. An invoice requests payment; the invoice-to-receipt guide covers recording money received, and credit notes document adjustments where appropriate. Country and industry pages adapt starting fields without generating new combinations.
