# Subcontractors

Register the companies you bring on the project so work is attributed to the right one.

A subcontractor is a company you bring onto a project. Registering them means work activities can be
attributed to the right company, which is what makes the day board and your reporting readable.

## Adding one

**ToolboxFM › Subcontractors › New subcontractor** — enter the business name, then choose the
projects where the company works. Leave the project list empty to make the subcontractor available on every
project.

A Subcontractor Supervisor's view of a subcontractor is limited to their own company, so a supervisor
from one trade cannot browse another trade's details.

## Deleting one

Deleting a subcontractor does not remove the work they did. ToolboxFM keeps the record in a tombstone
state: it stops appearing in pickers and lists, but the work activities, diary entries and history that
refer to it still resolve to a name rather than to a blank.

This matters more than it sounds. If deletion erased the company, your historical reporting would
quietly become wrong.
