Your own alternative to Baseplan
Job planning and scheduling for building contractors.
Baseplan: Quoted privately: roughly USD150 to USD1,200 a month per user, plus a USD5,000 to USD50,000 setup project.
We have not found an open-source project that does what Baseplan does well enough to list. That usually means the software is specialised, and the quickest way off it is your own version.
