Nobody here has retyped an invoice in a month.

The invoice starts from the job, not from a blank page. Customer, car, reg, MOT line: already there, because the diary already knew them. You add the work and the parts.

Trade accounts book through their own link. Every job logs itself against their account, and the weekly invoice builds itself with every registration listed, because some trade customers want every reg on the invoice.

Andy's Friday used to be seven trade invoices in biro. Scroll the paper diary, tot up the MOTs, copy every reg out longhand. It is three clicks now. Nobody sold him that fix; he described his Friday and it got built.
