Pricing & ranges
Exact quotes need a short scope call. These bands match what I typically see for solo lead delivery with clear milestones — they are not legally binding until we both sign something in writing.
AI agent systems
Focused MVP (one primary flow + RAG + basic ops): often mid four to low five figures USD depending on integrations. Multi-dashboard production systems with heavy compliance land higher.

MVP hardening or a thin vertical slice: typically low-to-mid four figures per milestone. Greenfield multi-tenant builds scale with surfaces (web, admin, mobile) and integrations.
FinTech / invoicing
Structured milestone delivery with signing, tax stages, and ERP sync: usually five to six figures total program cost depending on web+mobile, jurisdictions, and audit requirements.
What moves the estimate: number of integrations, compliance burden, team count needing onboarding, SLAs, and whether you need me to own mobile + web + backend vs one layer.
