Story

Why FinSight Was Created

"Can I trust this supplier? What if they don't pay me?"

This question haunted me for years. I got burned several times – uncollectible receivables, unnecessary business relationships that ended up with lawyers. I always asked myself: "Why didn't I look into them better?"

I knew the answer was in the financial statements. They're public, available, contain all the important indicators. But...

  • Pay thousands for an agency analysis? Just for one client?
  • Transcribe data into Excel and search for formulas online?
  • Install commercial software with monthly subscriptions?

None of those options were practical. I needed a quick verdict. Liquidity? Leverage? Profitability? Bankruptcy risk? Can they be trusted, or not?

So I created FinSight — the tool I needed for myself. And because it helped me, I decided to share it with other entrepreneurs. Free. No registration. No fees.

What Can FinSight Do?

In 5 minutes, it answers five key questions:

  • Liquidity — Does the company have enough money to cover obligations? (Current Ratio, Quick Ratio, Cash Ratio)
  • Leverage — Is the company too indebted? (Debt Ratio, Debt-to-Equity)
  • Profitability — Is the company generating profit? (ROS, ROE, ROA, EBITDA margin)
  • Bankruptcy Risk — Is bankruptcy looming? (Altman Z-Score, Interest Coverage)
  • Efficiency — How quickly does the company collect receivables? (DSO, Cash Conversion Cycle)

No registration. No fees. 5 minutes of work. Clear verdict.
Simply a tool that works.

Why FinSight

Comprehensive Financial Analysis in One Tool

Everything you need to understand your company's financial health. From basic indicators to advanced predictions.

Private and Secure

All data is processed exclusively locally in your browser. PDF export sends data to the server only for PDF generation - data is not stored and is immediately deleted after generation. It is not stored in a database or anywhere else. Subresource Integrity (SRI) protects against supply chain attacks.

Comprehensive KPIs

Profitability (ROS, ROE, ROA), liquidity (3 types), leverage, asset turnover, and other key indicators for performance evaluation.

Predictions and Trends

Analyze development across up to 4 periods. Three prediction scenarios (optimistic, realistic, pessimistic) with trend visualization.

Altman Z-Score — Bankruptcy Risk

Predictive model for assessing bankruptcy risk developed by Professor Edward Altman. The Z′ model is optimized for small and medium enterprises and combines 5 key financial indicators (working capital, retained earnings, EBIT, revenue, and equity) into one score. Result: Z-Score > 2.99 = safe zone, 1.81–2.99 = gray zone (monitor), < 1.81 = high bankruptcy risk. Enables early identification of financial problems.

Beneish M-Score — Manipulation Detection

Model for detecting accounting manipulation developed by Professor Messod Beneish. Analyzes 8 components (DSRI, GMI, AQI, SGI, DEPI, SGAI, LVGI, TATA) and identifies suspicious changes in financial statements that may signal aggressive accounting or earnings manipulation. Result: M-Score < -2.22 = low probability of manipulation, > -2.22 = increased risk. Important for due diligence and investment decisions.

Cash Flow Analysis

Operating, investing, and financing cash flow. Track where money comes from and where it goes.

Break-Even Analysis

Find the break-even point — how much revenue you need to cover all costs. Including safety margin.

PDF Export

Professional PDF report generated on the server using Dompdf. Contains all advanced models, charts, trends, warnings, and bank traffic light. Perfect for presentations to bankers or investors. PDF export sends data to the server only for PDF generation - data is not stored and is immediately deleted.

Key Indicators

All Key Indicators in One Place

FinSight calculates and evaluates 30+ professional financial indicators used by banks, investors, and auditors to assess company financial health.

Profitability

  • ROE (Return on Equity) Return on equity. Shows how efficiently the company uses owners' capital. A value > 15% is considered good.
  • ROA (Return on Assets) Return on assets. Measures the efficiency of using all company assets. A value > 5% is considered good.
  • ROS (Return on Sales) Profitability of sales. Shows how much profit is generated per unit of revenue. A value > 5% is considered good.
  • EBITDA Margin Earnings before interest, taxes, and depreciation relative to revenue. Shows operating performance without the influence of financing and taxes.

Liquidity

  • Current Ratio Ratio of current assets to short-term liabilities. A value of 1.5–2.5 is considered optimal. < 1 signals liquidity problems.
  • Quick Ratio Ratio of (current assets - inventory) to short-term liabilities. Measures the ability to quickly cover liabilities without selling inventory. A value > 1 is considered good.
  • Cash Ratio Ratio of cash to short-term liabilities. The strictest measure of liquidity. Shows the ability to immediately pay liabilities using only cash.

Leverage

  • Debt Ratio Share of external sources in assets. A value > 60% signals high leverage. Optimal value depends on the industry.
  • Debt-to-Equity Ratio of debt to equity. Shows how much debt the company has per unit of equity. A value > 2 is considered high.
  • Interest Coverage Interest coverage (EBIT / interest). Measures the company's ability to cover interest expenses from operating profit. A value > 3 is considered safe, < 1.5 signals risk.
  • Net Debt / EBITDA Key banking indicator. Shows how many years it would take to repay net debt at the current EBITDA level. A value < 3 is considered good, > 5 signals high risk.

Turnover and Efficiency

  • Asset Turnover Asset turnover. Measures how much revenue each unit of assets generates. Higher value = more efficient asset utilization.
  • DSO (Days Sales Outstanding) Average collection period for receivables in days. Lower DSO = faster collection = better cash flow. Optimal value depends on the industry.
  • DPO (Days Payable Outstanding) Average payment period for supplier liabilities in days. Higher DPO = better cash flow, but may signal payment problems.
  • Cash Conversion Cycle Total cash flow cycle (DSO + DIO - DPO). Shows how long it takes to convert inventory investments back into cash. Lower CCC = better working capital management.
✓ Return on Sales (ROS)
✓ Return on Equity (ROE)
✓ Return on Assets (ROA)
✓ EBITDA Margin
✓ Current Liquidity
✓ Quick Liquidity
✓ Cash Liquidity
✓ Total Leverage
✓ Debt-to-Equity
✓ Asset Turnover

Methodology and Know-How

How FinSight Works Technically

Transparent overview of calculations, API integrations, and local data processing

Local Data Processing

  • All calculations run in the browser FinSight uses pure JavaScript (Vanilla JS) without server dependencies. All financial indicators (ROE, ROA, ROS, liquidity, leverage) are calculated directly in your browser from the data you enter.
  • No data is stored All inputs (financial statements) and outputs (calculations, charts) remain only in your browser. Only localStorage is used to store theme preferences (light/dark mode).
  • Instant results All calculations run synchronously when entering data. Charts are generated using Chart.js directly in the browser without the need for server communication.

Financial Indicator Calculations

  • Profitability ROS = Net Profit / Revenue × 100%, ROE = Net Profit / Equity × 100%, ROA = Net Profit / Assets × 100%. All calculations use standard accounting formulas according to accounting standards.
  • Liquidity Current Ratio = Current Assets / Short-term Liabilities, Quick Ratio = (Current Assets - Inventory) / Short-term Liabilities, Cash Ratio = Cash / Short-term Liabilities. Values are calculated in real-time when data is entered.
  • Leverage Debt Ratio = External Sources / Assets × 100%, Debt-to-Equity = External Sources / Equity, Interest Coverage = EBIT / Interest, Net Debt/EBITDA = (External Sources - Cash) / EBITDA.
  • Altman Z-Score We use the modified Z' model for private companies: Z' = 0.717×X1 + 0.847×X2 + 3.107×X3 + 0.420×X4 + 0.998×X5, where X1-X5 are ratio indicators (working capital, retained earnings, EBIT, equity, revenue relative to assets).
  • Beneish M-Score 8-factor model for detecting accounting manipulation: M = -4.84 + 0.92×DSRI + 0.528×GMI + 0.404×AQI + 0.892×SGI + 0.115×DEPI + 0.172×SGAI + 4.679×TATA - 0.327×LVGI. Calculation runs locally for each period.

Data Retrieval from API (ARES Integration)

  • Public Register (VR) FinSight uses ARES REST API (https://ares.gov.cz/) to obtain basic company information (name, company ID, establishment date, status, capital, statutory bodies, shareholders). Data is loaded via PHP proxy script (ares.php), which ensures secure API calls and JSON response parsing.
  • Insolvency Register (IR) Like VR, insolvency data is also obtained via ARES REST API. The proxy script checks whether the company is in insolvency, reorganization, or liquidation. Results are displayed in the "Company Profile" tab.
  • Tax Portal (VAT) FinSight calls the Financial Administration's SOAP API (https://adisrws.mfcr.cz/) to check VAT payer reliability and obtain a list of public bank accounts. SOAP requests are generated in PHP proxy and responses are parsed into JSON format for the frontend.
  • API Call Security All API calls go through server-side PHP proxy (ares.php), which ensures correct HTTP headers, SSL verification, and error handling. The frontend never calls the API directly - this ensures protection of API keys and CORS policies.
  • Cache and Optimization ARES data is stored in localStorage for faster repeated loading. When the company ID changes, the cache is automatically refreshed. API calls run in parallel using Promise.all() for maximum speed.

PDF Export

  • Server-side Generation with Dompdf PDF is generated on the server using the Dompdf library (PHP), which provides better rendering quality and more robust layout than client-side solutions. Data is sent to the server only for PDF generation - it is not stored and is immediately deleted after generation.
  • Chart Capture Charts from Chart.js are converted to images (JPEG) directly in the browser using canvas.toDataURL(). Images are sent to the server as base64 data URLs together with other data for PDF generation.
  • Complete PDF Document Structure PDF contains: cover with rating, management summary with warnings, indexed performance (Base 100), detailed trends and volatility, graphical analysis (revenue and profitability development), bank traffic light with traffic light indicators, Altman Z-Score, Beneish M-Score, Valuator, and other advanced sections.
  • Professional Styling and Formatting PDF uses modern design with table layout for maximum robustness: color indicators for risk values, traffic light semaphores, progress bars, uniform fonts (DejaVu Sans), and correct number alignment with diacritics.
  • Security and Privacy PDF export sends data to the server only for PDF generation. Data is not stored in a database or file system - all data is processed only in memory and immediately deleted after PDF generation. Explicit documentation in the code confirms that the script does not use a database or file system.

Technical Stack

  • Frontend Pure HTML5, CSS3, and Vanilla JavaScript (no frameworks). Chart.js for charts, Subresource Integrity (SRI) for CDN script security. All libraries are loaded from CDN (cdnjs.cloudflare.com) with checksums.
  • Backend (API proxy + PDF generation) PHP 7.4+ for proxy scripts (ares.php, ares_lite.php) and PDF export (export.php). Dompdf for server-side PDF report generation. cURL for HTTP/HTTPS requests, SOAP for communication with the Financial Administration.
  • No Database FinSight does not use any database. All data remains in the user's browser. Only localStorage for caching ARES data and theme preferences.

The project is my personal contribution to supporting the entrepreneurial environment. I believe that financial literacy is the foundation of every company's success.
