Savings proposal
A 25-editor team on Voiceflow Pro pays about $1,254 a month. Self-hosting Flowise costs about $132 a month to run plus $480 to set up, so it pays for itself in month 1 and saves about $39,912 over three years.
List price: Voiceflow Pro, billed annually. Pro is $54 a month with one editor; extra editors are $50 each. Usage (messages, tokens) is billed on top. Source, checked 2026-10-07.

Assumptions you can change
Self-hosting Flowise usually means one small container and a database. Hours are for one engineer; the server cost is a typical cloud VPS with backups and grows with the number of people using it.
Not included: paid editions or features of Flowise (see What's free?), large data migrations, and compliance work. All amounts in US dollars at list price; your negotiated price may differ.
