The target customer (small roofing contractors still transcribing paper sheets by hand) is real, the pain is weekly and measurable, and the kit is priced to build a legitimate business: **$149\/crew\/month** with a 96% gross margin.\u003c\/p\u003e\u003cp\u003eThis is not a tutorial.

Do not demo before running this test.\u003c\/p\u003e\u003cp\u003e**Xero employee sync:** Full employee sync requires a Xero Payroll subscription.
