We need someone to answer enquiries, book visits, chase quotations, update customers and check invoices.

For companies hiring office support
Before another desk, look at the load.
You may still need the person. But routine coordination should not automatically require another full office salary.

The load underneath
Most of the brief is a route, not a role.
Answering, booking, following up, updating and closing are repeatable handoffs. Manage the route; keep the person for judgement.

An honest hiring decision
Delay it. Refocus it. Or hire clearly.
Control the routine first. If the hire is still needed, the brief is sharper and the person is not being recruited to carry reminders.
Remove repetition. Keep judgement close.Start with the advertised role
