> **ReconcileX** is an enterprise-grade financial reconciliation engine designed to eliminate manual spreadsheet matching while permanently solving the dual perils of **LLM mathematical hallucination** and **confidential financial data leakage**.
>
> By decoupling **deterministic mathematical verification** (`pandas`, `rapidfuzz`, bounded subset-sum algorithms) from **agentic semantic reasoning** (local Ollama / Cloud vision models), ReconcileX guarantees 100% arithmetic accuracy while effortlessly resolving complex corporate accounting edge cases: counterparty DBA aliases, bundled 1-to-N batch disbursements, international wire fee deductions, statutory ZATCA/VAT compliance audits, and bilingual Arabic/English receipts.

## πΈ Visual Showcase
ReconcileX combines high-performance financial engineering with a refined, human-crafted user experience built specifically for corporate finance teams and auditors.
### 1. Executive KPI Dashboard & Chart.js Visual Analytics
Real-time reconciliation status cards (Reconciled Value, Open Payables, Cash Discrepancy, Match Rate), coupled with dynamic **Method Mix** breakdown and **Settlement Timeline** analytics.
---
### 2. Interactive Dual Split-Ledger Workspace & Floating Match Dock
Side-by-side Accounts Payable (AP) and Bank statement feeds. Selecting unmatched items activates the persistent **Floating Action Match Dock**, computing live balance deltas ($\Delta$) for 1-click manual overrides.
---
### 3. Forensic Document Inspector Drawer & SHA-256 Fingerprinting
Slide-out document drawer displaying line-item breakdowns, tax calculations, OCR confidence scores, raw text streams, and immutable **SHA-256 cryptographic fingerprints** for forensic audit defensibility.
---
### 4. Statutory Tax & ZATCA Compliance Audit Engine
Automated detection of VAT variances, statutory rate compliance checks (e.g., 15% Saudi ZATCA, 14% Egyptian ETA), mathematical tax recalculations, and anomaly flagging across all parsed invoices.
---
### 5. In-Dashboard Rule & Parameter Tuning Studio
Interactive tolerance control panel allowing finance controllers to fine-tune matching horizons (Date Β±Days, Vendor Strictness %, Wire Fee Tolerance $\Delta$, and Combinatorial Bundle Limits) with live auto-refresh.
---
### 6. Human-Crafted Dark Mode Ergonomics
Thoughtfully designed dark theme adhering to ergonomic contrast guidelinesβeliminating harsh neon glows and blue-light eye strain during month-end closing marathons.

## π Key Capabilities & Feature Matrix
| Capability | Technical Mechanism | Real-World Benefit |
| :--- | :--- | :--- |
| **Zero-Hallucination Math** | Pure Python 4-Pass Deterministic Engine | LLMs are never permitted to balance ledgers or perform arithmetic; eliminates phantom rounding and corrupted financial statements. |
| **Local-First Privacy** | On-premise vector parsing (`pdfplumber`) & Local VLM (`Qwen2.5-VL` via Ollama) | Zero financial records, banking tokens, or PII leave the client infrastructure; fully GDPR, SOC2, and banking compliant. |
| **Bilingual Arabic/English OCR** | Native RTL layout & Dual-Engine parser (`EasyOCR` / `Surya` / `Qwen2.5-VL` / `Gemini`) | Seamlessly processes Saudi ZATCA e-invoices, Egyptian tax forms, UAE invoices, and global corporate receipts. |
| **Bundled Payment Detection** | Bounded Combinatorial Subset-Sum Solver ($O(N \cdot K)$) | Instantly detects when a single bulk bank payout settles 2, 3, or 4 separate vendor invoices in a single batch. |
| **Bank Fee Discrepancy Tolerance** | Bounded delta tolerance algorithm ($\Delta \le \$25.00$) | Auto-reconciles foreign exchange spreads, wire transfer intermediary charges, and merchant interchange fees. |
| **Semantic Alias Disambiguation** | Agentic Reasoning Intermediary (Local / Cloud LLM) | Disambiguates cryptic bank statements (`STRIPE *ACME HOSTING`) with formal vendor master entities (`Acme Cloud Hosting LLC`). |
| **Interactive Split-Ledger** | Dual-pane AP & Bank feed with Floating Match Dock | Provides finance teams with instantaneous manual override capabilities and live variance balance calculations. |
| **Forensic Document Inspector** | Slide-out drawer with SHA-256 digest & OCR stream | Offers auditors an unalterable chain of custody and instant document inspection without external PDF viewers. |
| **Tax & ZATCA Compliance Audit** | Deterministic VAT rate recalculation & rule engine | Flags non-compliant tax rates, missing vendor VAT IDs, and rounding discrepancies prior to statutory tax filings. |
| **ERP Journal Voucher (JV) Export** | Balanced double-entry generator (ERPNext, Odoo, QuickBooks) | Auto-generates balanced Journal Entries (Debit AP, Credit Bank, Debit Bank Charges) ready for ERP ingestion. |
| **Model Context Protocol (MCP)** | Standard JSON-RPC stdio server (`mcp>=2.2.0`) | Exposes 5 native reconciliation tools directly to AI IDEs (Antigravity, Cursor, Claude Desktop). |

## πΌ Enterprise Modules & Workflows
### 1. Interactive Dual Split-Ledger & Floating Match Dock
Finance teams deal with edge cases that automated algorithms may miss. ReconcileX includes a high-productivity dual-pane ledger:
* **Accounts Payable Ledger (Left Pane):** Filter by vendor, date range, or invoice status.
* **Bank Activity Feed (Right Pane):** Filter by bank narration, debit value, or settlement timestamp.
* **Floating Match Dock:** Selecting an invoice and a bank line automatically triggers the dock at the bottom of the viewport, calculating:
$$\Delta = \text{Bank Amount} - \text{Invoice Amount}$$
If $\Delta > 0$, it is classified as an unexplained surplus; if $\Delta < 0$, it can be booked directly as a bank wire transfer fee with 1 click.
### 2. Forensic Document Inspector
Auditability requires inspecting the raw document evidence behind every transaction:
* View structured invoice metadata (Invoice Number, Counterparty, Currency, Dates).
* View arithmetic subtotal, statutory tax rate, and computed grand total.
* Cryptographic **SHA-256 fingerprint** of the document payload ensures unalterable custody records.
* Raw OCR text terminal reveals full document context without switching to an external PDF viewer.
### 3. Statutory Tax & ZATCA Compliance Audit
In emerging markets and regulated jurisdictions (such as Saudi Arabia ZATCA e-Invoicing Phase 2, Egypt ETA, UAE FTA), tax errors incur severe financial penalties:
* Automatically computes the effective tax percentage:
$$\text{Effective Rate} = \frac{\text{Tax Amount}}{\text{Subtotal}} \times 100$$
* Compares calculated rates against statutory thresholds (e.g. 15% VAT).
* Identifies missing Tax IDs, uncalculated sales tax, or math rounding discrepancies.
### 4. Balanced ERP Journal Voucher (JV) Generation
Once reconciled, transactions must be booked into enterprise resource planning software:
* Generates balanced double-entry accounting records adhering to the fundamental accounting equation:
$$\sum \text{Debits} = \sum \text{Credits}$$
* Automatically splits transactions:
* **Debit:** Accounts Payable (Vendor Account)
* **Debit:** Bank Wire Charges & Exchange Variance (Expense Account)
* **Credit:** Operating Cash / Bank Account (Asset Account)
* Exportable in standard JSON and CSV formats tailored for **ERPNext**, **Odoo**, **QuickBooks Online**, and **NetSuite**.

## π οΈ MCP Server Interface (For AI IDEs)
ReconcileX implements a native **Model Context Protocol (MCP)** server over standard I/O (`stdio`). This allows AI agents inside **Google Antigravity**, **Cursor**, or **Claude Desktop** to perform reconciliations directly through conversational prompts.
### Configuration (`mcp_config.json` / `claude_desktop_config.json`)
```json
{
"mcpServers": {
"reconcilex": {
"command": "python",
"args": ["-m", "reconcilex.cli.main", "mcp"],
"env": {
"RECONCILEX_LLM_PROVIDER": "local",
"OLLAMA_BASE_URL": "http://localhost:11434"
}
}
}
}
```
### Exposed MCP Tools
| Tool | Parameters | Description |
| :--- | :--- | :--- |
| `ingest_sources` | `paths: List[str]` | Recursively scans folders to parse and normalize digital PDFs, scanned receipts, and bank CSVs. |
| `run_deterministic_match` | `tolerance_days: int = 3`, `fee_tolerance: float = 25.0` | Executes the 4-pass deterministic engine and computes reconciliation summary metrics. |
| `get_unmatched_records` | *None* | Returns remaining open invoices and unsubstantiated bank transactions for agentic review. |
| `resolve_ambiguity` | `invoice_id`, `tx_id`, `reasoning`, `fee_amount` | Links an ambiguous pair with an immutable forensic audit trail justification. |
| `export_reconciliation_report` | `format: "excel" \| "markdown"` | Produces a comprehensive multi-tab Excel workbook or structured Markdown audit report. |
