JobStack vs. JoistWhere JobStack fits
Service Fusion and Joist are both built to scale field-service teams — power a solo operator or small crew pays for but doesn't run day to day. JobStack takes the opposite bet: the daily essentials — scheduling, estimates, invoicing, and payments — with AI on the time sinks (texting back leads, drafting estimates from a voice note, chasing unpaid invoices), flat per-tier pricing, and setup in minutes.
