At the end of a project, money that was earned long ago is missing
Hourly work without a signature, extra quantities, changes agreed on site: what was arranged on the job often never makes it into the final invoice. The evidence is scattered across emails, plans, photos and people's heads. At the same time, clients increasingly check invoices with software and cut whatever lacks evidence.
