Getting started guide
How the agent onboards to your existing books and bank feeds.
The AI Accountant Agent — not an AI-enabled tool
Your books, run by an agent that actually does the work.
Nebula Books doesn't suggest journal entries for you to enter — it enters them. It reconciles transactions, chases invoices, files GST returns, and closes the books, while you review and approve.
- SG / IRAS-ready
- Bank-level encryption
- Human-reviewed by default

Agent, not assistant
“AI-enabled” software still hands the work back to you.
Most accounting tools bolt a suggestion engine onto the same manual workflow. Nebula Books is built the other way around — the agent does the task, and you stay in control of the decisions that matter.
| Task | Traditional software | AI-enabled tools | Nebula Books agent |
|---|---|---|---|
| Entering transactions | Manual, line by line | Auto-categorized — you confirm each one | Entered and posted automatically |
| Reconciling the bank | You match every line yourself | Suggests matches for you to accept | Reconciles and flags only real exceptions |
| GST & tax filings | You prepare and file it yourself | Drafts a form you still assemble | Drafts, checks, and files — you approve |
| Late invoices | You chase customers manually | Reminds you to follow up | Sends the reminders itself, on schedule |
Features
One agent, every ledger task.
It is one agent across the whole ledger, so nothing is handed between tools, and nothing waits for month-end to be picked up.
Sales & invoicing
Drafts quotations, raises invoices, and follows up on overdue payments without a reminder from you.
Purchasing & bills
Matches vendor bills to purchase orders and schedules payments before due dates slip.
Bank reconciliation
Reconciles every transaction against your books and only surfaces the exceptions that need a decision.
Compliance & filing
Prepares and files GST F5 returns, XBRL financial statements, and annual filings on schedule.
Books & journals
Posts journal entries and keeps a clean chart of accounts, so your books close on time every month.
Reporting
Turns your ledger into board-ready reports the moment you — or your accountant — need them.
