Double is ledger-native and AI-driven for a single set of books. Synoro adds named role-based agents, a firm-wide client portal, and per-client economics across the whole book.

The gap
Double prices per client company (Core $10 · Plus $25 · Scale $50) with tax and email as separate paid add-ons ($200/month and $10/month per inbox). It automates close for one entity at a time, not the firm-wide layer (engagement letters, margin across the book, named role agents).
Synoro is $5 per company per month, all included — unlimited users, tax and email in the same price. Plus the firm-wide portal, agents, and per-client margin Double doesn't cover.

The difference
Double automates close work entity by entity — Core $10, Plus $25, Scale $50 per client, with add-ons for tax and email. Firms still need engagement letters, roles, governance, and margin across every client. Synoro is $5 per company per month, all included, with unlimited users and the practice layer Double doesn't cover.
Synoro's Categorization, Staff Accountant, and CFO agents own roles with limits and audit trails — supervised by your firm policy.
See which clients make money and which don't — revenue, human cost, and AI cost computed per client org, not guessed in a spreadsheet.

Per-client revenue, cost, and margin — the proof behind the claim.
