⚡ The case in 30 seconds

AI lets you query your financial data the way you ask a question

The finance departments of SMBs and mid-market companies spend 40 to 60% of their time collecting and formatting data, at the expense of value-added analysis. New conversational AI solutions make it possible to ask questions in natural language about your financial data: "What is the budget variance by department this quarter?", "Which customers have outstanding receivables over 90 days?". Response time: under 30 seconds, versus 2 to 4 hours in manual mode.

This use case shows how an industrial mid-market company in the Hauts-de-France region cut the production time of its monthly reports by a factor of 5 while improving the analytical quality of its finance department.

The problem: CFOs drowning in data collection

The finance departments of SMBs and mid-market companies are caught between growing reporting requirements and unsuitable tools. Three pain points dominate.

🕐

Time-consuming, manual monthly reporting

Producing the monthly report ties up the finance department for 5 to 8 working days: extracting data from the ERP, consolidating in Excel, formatting tables, writing commentary. With 3 people in finance, this represents 15 to 24 person-days per month devoted to production, not analysis.

Ad hoc questions impossible to handle in real time

When the CEO asks in committee "What is our margin by product line this month?", the answer arrives 48 hours later. This latency prevents responsive decision-making. Executives make strategic decisions on data that is 2 to 4 weeks old, a major competitive handicap.

🔍

Anomalies detected too late

Without alerting tools, budget overruns, unpaid invoices and accounting errors are only detected at the monthly, sometimes quarterly, close. One mid-market company discovered, 6 months after the fact, a recurring billing error representing 120,000 euros in lost revenue. Automated detection would have flagged the anomaly in the very first month.

The solution: a conversational financial assistant

Our approach relies on an AI assistant connected to your financial data, able to answer in natural language and produce analyses in real time.

💬

Natural language queries on the data

The assistant translates questions in plain English into SQL queries on your financial database. "Show me the top 10 customers by revenue this quarter" instantly produces a formatted table with a chart. The system understands accounting vocabulary (working capital, EBITDA, DSO, receivables) and adapts to the structure of your chart of accounts.

📑

Automatic report generation

Reporting templates are configured once: monthly P&L, budget tracking, cash flow statement, variance analysis. The AI generates them automatically at each close with analytical commentary. The CFO now only validates and enriches. The production time of the monthly report has dropped from 5 days to 1 day.

🚨

Proactive anomaly detection

The system continuously monitors financial flows and alerts on anomalies: duplicate invoice, budget variance above a threshold, customer overdue on payment, abnormal change in an expense item. Each alert comes with a diagnosis and a recommended action. 85% of anomalies are detected within 24 hours versus 30 days on average before.

Step-by-step implementation

1

Data audit and connection to sources (week 1-2)

Identify your financial data sources: ERP (Sage, Cegid, SAP), billing tool, bank statements, Excel tracking files. Assess the quality and completeness of the data. Configure the connectors to feed a centralized data warehouse. For SMBs on Sage or EBP, a simple automated daily export is enough to get started.

2

Configuring the assistant and reports (week 3-4)

Configure the language model with your business vocabulary (chart of accounts, department names, specific indicators). Create the automated reporting templates: P&L, budget vs. actual, forecast cash flow. Define the alert rules (variance thresholds, payment terms, unusual amounts). Test with the data from the last 6 months to validate the reliability of the results.

3

Training, deployment and scale-up (week 5-8)

Train the finance department to use the assistant (3-hour workshops with practical cases on their real data). Deploy first in read-only mode (queries and reporting) then activate automatic alerts after 2 weeks of validation. Collect user feedback to refine the prompts and add new types of queries. Gradually extend to other departments (sales, HR) for the indicators that concern them.

Frequently asked questions

Can AI replace a management controller?

No, AI does not replace the management controller but considerably boosts their productivity. AI excels at extracting data, calculating indicators and producing standardized reports. The controller brings the irreplaceable added value: interpreting results in their business context, strategic recommendations, dialogue with operational teams and risk anticipation. AI frees up 40 to 60% of their time for these high-value tasks.

Is my financial data safe with an AI solution?

Security depends on the chosen deployment mode. In private cloud mode (Azure, AWS within your tenant), the data stays in your environment and benefits from end-to-end encryption. In API mode (OpenAI, Anthropic), the data passes through the provider but is not used for training if you use the business APIs. For the most sensitive data, favor a self-hosted open source model (Mistral, Llama) which guarantees that no data leaves your infrastructure.

Which accounting systems and ERPs are compatible?

AI-based financial analysis solutions connect to most systems on the market via API or data export: SAP, Sage, Cegid, EBP, QuickBooks, Pennylane, and the main ERPs (Odoo, Microsoft Dynamics, NetSuite). The most common connection remains the CSV or Excel export from your accounting tool, which the AI analyzes directly. For real-time integration, allow 2 to 4 weeks of additional development.

How much does it cost to set up such a solution?

For an SMB, allow between 10,000 and 30,000 euros for the initial deployment (audit, configuration, integration, training) and 500 to 1,500 euros per month for operation (AI licenses, hosting, maintenance). ROI is generally reached in 4 to 6 months thanks to the time saved on reporting (10 to 15 hours per week for a 3-person finance department) and to faster anomaly detection.

Technical architecture

Claude 3.5 Sonnet

Natural language to SQL translation

Preferred model for converting questions into complex SQL queries. Excellent at understanding accounting terms and at generating multi-table queries. First-try correct query rate: 92%.

DuckDB + dbt

Analysis and transformation engine

DuckDB serves as the in-process analytical engine for the SQL queries generated by the AI. Combined with dbt for data modeling, it enables analyses over millions of rows in a few seconds without heavy infrastructure. Ideal for SMBs that do not want to invest in a full data warehouse.
