Why teams switch

Clean books start before the accountant sees them.

Zeng Book is built for the messy work before final accounting: collecting evidence, matching payments, keeping invoices tied to project context, and making month-end review less frantic.

Receipts show up after the job
Photos, paper slips, and supplier PDFs arrive late, without the GST or project context finance needs.
Invoices lose their source trail
An invoice number is easy to find. The quote, claim stage, acceptance note, and documents behind it are not.
Payment review lives in another place
Bank statements, collections, overdue invoices, and project costs are reviewed in different tools.
Month-end becomes a chase
Owners want cashflow answers while PMs and bookkeepers are still hunting for evidence.
Actual app surfaces

From source documents to project-ready books.

Scan, match, invoice, and review from the same workspace your project team already uses. The product preview uses the same dashboard structure, tables, and toolbar actions as the app.

One view for cash, claims, and work in progress
See collected value, collectable invoices, quote pipeline, active work, priority items, and recent transactions without rebuilding another spreadsheet.
  • Collected and collectable totals
  • Quote and invoice pipeline
  • Priority queue for follow-up
