Breezing Short Demo: Crypto Accounting Made Simple

As answered by people managing Apache Flink and Breezing.
Breezing's answer:
Most crypto accounting tools focus on tax reporting for individuals or basic transaction imports. Breezing is built specifically as a subledger for professional accountants, meaning it handles the full accounting workflow: journal entries that update without delete/repost, invoice closure (AP/AR), opening balances, cost center sync, and DeFi rewards accrual. It supports 40+ blockchains and 15+ exchanges pushing directly into Xero, QuickBooks, and Bexio. It's also SOC 2 Type II certified and Swiss-made, which matters to enterprise finance teams and firms with compliance requirements.
Breezing's answer:
The main competitors (Cryptio, Bitwave, Cryptoworth) are either enterprise-only with opaque pricing or built around tax exports rather than true accounting integration. Breezing sits in the middle: professional-grade accounting features with transparent pricing starting at $29/mo, a Xero Partner badge, and details like journal entry edits without deleting/reposting that accountants actually care about. For firms already working in Xero or QuickBooks, Breezing is the purpose-built connection, not a workaround.
Breezing's answer:
Professional accountants and accounting firms that manage crypto for their clients, plus finance managers and CFOs at companies that hold or transact in crypto. Not retail users or individual tax filers. The ICP is someone who already lives in Xero or QuickBooks and needs crypto to flow into it cleanly, with audit-ready records.
