Double-Entry Ledger Postings

Invoice is in draft mode. Debits and Credits are prepared but not yet committed to the journal.

In a robust double-entry system, a document does not affect ledger balances until it is officially Committed/Posted.

Active Ledger Balances

Core Features Spotlight

An institutional-grade, multi-tenant accounting core engineered for strict ledger standards, VSHR payroll integration, and high performance.

Double-Entry Verification

Automated balance checks prevent postings unless debits match credits exactly. Bulletproof journal entries are strictly rounded with high-precision decimals.

Flattened Realtime DB Schema

Engineered with a high-performance flattened JSON database layout on Firebase Realtime Database. Scans and reads stay isolated by tenant (`companyId`) so you never download bulky transaction sub-collections when accessing metadata.

VSHR Payroll Ledger Adapter

Integrated with external HR systems like VSHR. Automatically posts perfectly balanced journal lines mapping payroll expenses (salary, pensions, taxes) to payroll payable accounts with comprehensive audit logging.

Role-Based Multi-Tenancy

Rigorous data isolation gates company memberships. Assign Viewer, Manager, Accountant, and Admin roles mapped securely across global database path security rules.

PDF Prints & Export

Instantly print clean, client-facing PDF invoices, bills, and payment vouchers. Perform batch exports to CSV across lists with single-click actions.

Financial Statements

On-demand balance sheets, cash flow statement calculations, and interactive AR/AP aging metrics generated automatically from historical ledger journals.

Recurring Workflows

Automate routine client invoicing with schedule profiles. Build Credit Notes instantly linked with reversal entries to ensure historical records are never deleted.
