When you search “site planner”, Google fills the page with ERP, Gantt and estimates. If what hurts is who I send tomorrow to each job, you need a site crew planner: a board, not a price bank.
The Excel + WhatsApp problem
- Different versions on the manager’s PC and in admin.
- Last-minute changes that do not reach everyone.
- Nobody sees conflicts (two sites, sick leave, van) until it is already late.
What SignaPlan does here
- Assign people to sites by dates, with a clear view.
- Spot clashes before the labourer is in the wrong place.
- Connect to time clocking and fleet when you need them.
It is not a full ERP (and that is fine)
If you need BC3, certificates and invoicing, there are tools for that. SignaPlan covers the day-to-day of people and vehicles. You can start here and link an ERP later if you need to.
