Financial operating system

Your books run themselves.
GST is always ready.
No one shares bank passwords again.

Not accounting software with AI bolted on. A system where humans and AI agents operate on the same financial primitives — creating invoices, reconciling statements, filing returns. Deterministic. Auditable. Open source.

  • Every action audited. Every change traced. Every operator accountable.
  • GSTR-1 and GSTR-3B auto-generate from live invoice data.
  • Bank reconciliation that handles 70%+ of entries automatically.
  • AI agents execute financial operations — not generate suggestions.

The Reality

This is how India manages finances today.

It's not a workflow problem. It's a system architecture problem.

"Bhai, password bhej de"

Bank credentials shared on WhatsApp. GST portal logins forwarded in family groups. No audit trail. No accountability. One leak and everything burns.

Month-end madness

CAs drowning in bank statements, mismatched entries, and pending reconciliations. The 20th of every month is a battlefield. Sleep-deprived humans copying data between tools.

Fragmented everything

Tally for accounting. Excel for reconciliation. WhatsApp for communication. Some portal for GST. Nothing talks to each other. Data lives in silos.

Vendor lock-in

Years of data trapped in proprietary formats. Can't export. Can't switch. Can't self-host. Your financial data belongs to someone else's server.

The Shift

Accounting as a system, not software.

This is a new category. Not an upgrade. Not an AI add-on.

Old World Hisaabo
UI-driven Humans click buttons and fill forms Action-driven Financial primitives that anything can execute
Humans operate Systems need a person at the keyboard Humans + Agents operate Same API, same actions, different operators
AI as chatbot "Ask me anything" but can't do anything AI as operator Agents that execute, reconcile, and file
Month-end crunch Books close when humans finish entering data Always-ready books Real-time double-entry, continuously reconciled
Credential sharing Passwords on WhatsApp to "get things done" Role-based access Granular permissions, full audit trail
The Adoption Wedge

Stop sharing bank passwords.
Start controlling access.

This is why CAs switch. Not features — trust.

5 roles. Zero credential sharing.

Superadmin, Admin, Seller Manager, Seller, Accountant — each with scoped permissions per resource and action. CAs access client books via their own login. No one shares a bank password ever again.

Every action audited.

Every write operation logged with user, timestamp, and before/after state. Every invoice, payment, and journal entry traceable to a specific person — or agent. Defensible records.

Business isolation. By design.

Every API query scoped by business ID. Impossible to access another client's data by accident or intent. HttpOnly + Secure cookies. Argon2id hashing. No JWTs.

Right now, 63 million MSMEs share bank credentials on WhatsApp so their CA can download statements. Hisaabo replaces this with structured access control. This is the problem we solve first.

System Primitives

Not features. Not modules.
Financial actions.

Every workflow reduces to a small set of deterministic operations. Execute them from the UI, the CLI, or through an AI agent. Same result.

Aspect Before Hisaabo After Hisaabo
Client access Share login credentials on WhatsApp Role-based invite. Controlled access. No passwords shared.
Bank statements Manually import, match, reconcile line-by-line Auto-import, smart matching, agent-assisted reconciliation
GST filing Last-week panic. Manual data entry into portals. Always-ready returns. File GSTR-1/3B from within the system.
Audit trail Who changed what? Nobody knows. Every action logged. Full history. Defensible.
Monthly close 5-10 days of chaos per client 1-2 days. Mostly automated.
70% Less time on reconciliation
0 Credentials shared on WhatsApp
100% Audit trail coverage
Imagine this

You receive a GST notice.
Upload it. Get a response draft in minutes.

Not a chatbot suggesting what to do. The system reads the notice, pulls your invoice data, cross-references your GSTR-1 and GSTR-2B filings, identifies the discrepancy, and generates a structured response with supporting documents attached.

01 Upload the notice PDF
02 System matches against your ledger
03 Response draft with evidence, ready for your CA

This is what happens when your financial data is structured, deterministic, and always-ready — not locked in spreadsheets.

For Businesses

Replace Tally. Replace Excel.
Replace the chaos.

Simple enough for your shop floor. Powerful enough for your CA.

Tally

Done with Tally?

No more .900 files. No more Tally-only CAs. Your data is yours — export anytime, in standard formats. Modern interface that doesn't feel like 2005.

Vyapar

Outgrown Vyapar?

When you need real double-entry accounting, proper GST filing, and bank reconciliation — not just billing. Grow without switching tools again.

Excel

Still on spreadsheets?

Your books deserve structure. Start with invoicing, grow into full accounting. Mobile-first. Works on any device. No training needed.

Architecture

One system. Any operator.

Web dashboard, mobile app, CLI, and AI agents are all equal clients of the same API. There is no "AI layer." The entire system is the AI interface.

hisaabo mcp
$ hisaabo invoice create \
--party "Acme Corp" \
--amount 54000 \
--gst 18% \
--items "Consulting"
Invoice #INV-2024-0847 created
Journal entries posted (double-entry)
GST liability recorded (CGST + SGST)
E-invoice queued for IRP

Five equal clients

Web, mobile, desktop, CLI, and MCP server. All call the same 200+ typed procedures. An invoice created by Claude Desktop is byte-for-byte identical to one from the dashboard.

Agents execute, not suggest

AI agents call invoice.create with the same validation, same GST logic, same atomic numbering. The result is deterministic and auditable.

Financial ops as code

CLI for power users. MCP for AI agents. Bulk reconcile, batch categorize, scheduled compliance checks. Every command supports --json for piping.

Data Moat

Every firm makes the platform
better for every other firm.

1

Transaction patterns compound

When a CA categorizes "NEFT-SALARY" as salary expense, that rule applies across similar transactions. Every categorization trains the engine.

2

GST classifications validate

HSN codes confirmed for one business help validate classifications for others in the same industry. A textile trader's mappings benefit the next one onboarded.

3

Reconciliation accuracy compounds

More bank statements means better narration parsing. New UPI formats, changed NEFT descriptions — each resolved case makes the next one faster.

Comparison

A fundamentally different system.

No one else is building a system where agents execute financial operations.
