The $300/Month AI Stack That Replaces Your First Hire (Full Build)
The series finale: I assemble the full five-tool AI stack — support agent, phone receptionist, AI bookkeeping, CRM, and Zapier glue — into one working system in a single afternoon. You get the exact build order (customer side first — support agent and phone receptionist, then the back office — bookkeeping and CRM, then Zapier to tie it together), the three critical connections that unify the stack (lead → CRM with intake email, booked call → calendar + CRM log, payment → books with context), and the honest limits — where each tool still needs a human touch and which edge cases will bite you in month two. Then the full-year math: about $3,600/year all-in vs. $50,000+ for a first hire before benefits and management overhead. Real costs, real setup, no hype.
