One workspace. Two perspectives.
Shared visibility
100% invoice visibility
Owners always know what's invoiced and what's paid. Accountants no longer need to send status updates.
Always accounting-ready
100% automatically recorded
Every invoice stays organized and ready for bookkeeping, tax filing, and financial reporting.
Work together
1 shared workspace
Share customers, invoices, and documents in one workspace instead of endless phone calls and Zalo messages.

- Issue an invoice yourself when you need to, or let your accountant handle it.
- Track paid and unpaid invoices without waiting for monthly reports.
- Share one workspace with your accountant—no sending files back and forth.
- Stay ready for bookkeeping, tax filing, and year-end closing.
Works with the tools you already use
