In an inspection company
The work order is where scope creep shows up: additional welds tested, extra hours, standby time. Recording variations against the work order is what makes them invoiceable.
Work orders in AMPS
In AMPS the job is the work order. Client references such as PO and work order numbers are entered once on the job and filled automatically into the Word report and the Xero invoice. AMPS runs the job pipeline from creation and assignment through execution, reporting, timesheets and closure; a job marked ready for invoicing is visible to administrative staff in real time and the invoice is created in Xero.
