Creytix Books
A double-entry ledger engine — not a replacement for QuickBooks today.
A double-entry accounting engine (@creytix/books) that lives inside the OS — catalog status, not a general-ledger replacement for an established bookkeeping provider.
The ledger that stays in the same OS.
What it does for you
Same OS, no migration
Books runs as a Creytix catalog product — your chart of accounts, journal entries, and reports sit alongside every other tool instead of in a separate SaaS.
Double-entry engine
The @creytix/books package is a real double-entry accounting engine with a chart of accounts, journal, and trial-balance report — not a spreadsheet.
Honest scope
Books is a catalog product in development. It does not replace QuickBooks or Quicken today, and it is not affiliated with Align Finance (a consumer product on a separate path).
Capabilities
- Double-entry journal engine
- Chart of accounts
- Trial-balance and P&L report
- Payroll, inventory, billing and expense journal entries
- Invoicing
- OS-native — no separate login
Proof, not adjectives
- @creytix/books package ships
- The engine is built and tested — chart of accounts, journal with validation that rejects an unbalanced, fractional or negative entry, trial balance, P&L, and a balance sheet that reports whether it balances rather than assuming it.
- Connect registry entry
- Live at /app/books, and proven in company rather than alone: a cross-module scenario test runs a full month through inventory, purchasing, billing and payroll, asserting the ledger balances after every single step.
