The risks of AI in finance, and how to manage them

Risk 1: invented or wrong numbers

Language-based AI tools are built to produce fluent answers. When they lack the data, some still produce a figure that looks right: a sales total, a balance, a tax amount. This is often called hallucination. In accounts, a believable wrong number is worse than no number, because people act on it.

Controls:

• Only ask for figures from a tool that is connected to your books, and ask it to show the entries behind the figure.
• Spot-check against a standard report, such as the outstanding report or trial balance, before acting on a number.
• State the period, company and filters in every question.

Risk 2: outdated or invented tax answers

Indian tax rules change often. GST rates were restructured in 2025; thresholds, due dates and procedures move by notification; and the Income-tax Act, 2025 replaced the 1961 Act from 1 April 2026 with new section numbers. A model trained on older material may confidently quote the old rule, or invent a section or notification number that does not exist.

Controls:

• Use AI to understand concepts, not to decide rates, credits or deductions.
• Verify any rate, threshold or date on gst.gov.in, cbic-gst.gov.in or incometax.gov.in.
• Take tax positions with your CA, in writing for anything significant.

This is general information, not tax advice.

Risk 3: privacy of financial data

Ledgers, bank statements, salary sheets and customer lists are sensitive. They include other people's data too: customers' names, phone numbers and GSTINs, staff salaries and bank details. Pasting them into a public AI tool may mean the data is stored on servers you do not control, kept for an unknown period, or used to improve the tool.

Controls:

• Check where a tool stores data, for how long, who can access it, and whether it is used for training.
• Prefer tools built into your accounting system over copy-pasting into general tools.
• Share the minimum needed. To draft a reminder, the tool needs a name, bill number and amount, not your whole debtors list.
• Restrict who in your team can use AI on the full books, the same as for reports. See security of accounting data.

Risk 4: automating decisions that need a person

It is tempting to let AI send reminders, post entries, approve bills or change credit limits automatically. Each saves time until it goes wrong: a reminder sent for a bill already paid, a duplicate bill posted, a payment released to changed bank details.

Risk 5: losing the skill to check

If the team stops reading reports because “the AI tells us”, nobody notices when it is wrong. Keep the basics alive: someone should still read the Day Book, reconcile the bank, and understand the trial balance. AI should make that review faster, not replace it. See internal controls for small business.

Risk 6: fraud using AI

The same tools are used by fraudsters: realistic fake invoices, emails that copy a supplier's style asking for a change of bank account, even voice messages that sound like the owner asking for an urgent transfer. Simple rules help: confirm any change of bank details by calling a known number, never act on payment requests that come only by message, and keep two-person approval for large payments.

A one-page AI policy for a small business

1. Which AI tools are approved, and for what.
2. What data must never be pasted into an unapproved tool.
3. Every AI-prepared entry, message or report is checked by a named person.
4. No AI tool posts, pays, files or approves on its own.
5. Tax questions go to the CA; AI answers on tax are background only.
6. Any AI mistake found is noted, so the team learns where not to trust it.

How Cashflow OS approaches this

The AI assistant in Cashflow OS answers questions from the books synced from your Tally companies rather than from general knowledge, so answers can be checked against the same reports in the app. It does not file returns or give tax advice. Access follows the roles you set (owner, admin, accountant, staff, salesperson), and writing back into Tally is off until the owner switches it on. See user roles and access control.
