Is there genuinely free contractor estimating software?

Yes for the arithmetic. Free estimate generators and material calculators will get you a defensible number. What free versions generally do not do is produce a quote the customer can accept online, or remember what you quoted last time.

What free tools should a new contractor set up first?

Google Business Profile, then Search Console, then a way to capture leads on your own site. Those three decide whether anybody finds you and whether you hear about it when they do. Everything else can wait.

Are free contract templates safe to use?

A generated contract with a clear scope, payment schedule and change order clause is far better than the handshake most jobs start with. For a large or unusual job, have a lawyer read it. The cost of that is small against what a dispute costs.

When should a contractor start paying for software?

When the free version is costing you jobs rather than money. Usually that is speed of reply on new leads, and scheduling once you are running more than one crew.
