Introduction
===============
Tetxtra Insights is an evolution of the previous version (`Textra <https://textra.readthedocs.io/fr/latest/index.html>`_).
We aim to build a tool for financial summary generation with a goal to keep inference with local and limited computing resources.

For an easy comprehension of our tool here is a infernce pipeline :

1.Input
----------------
The process begins with one or multiple invoices (Images,Pdf files), which can be either client invoices or payment invoices.

2.Enhancement
----------------
The first step is enhancing quality of the invoices. with python libraries like
**OpenCV**, **PILOW**,...
Preprocessing Images (For Scanned or Photographed Invoices) by : 
  - Convert images to grayscale for simpler processing.
  - Denoise the image to remove background noise.
  - Binarize the image (convert to black and white) for better OCR (Optical Character Recognition) results.

   - You can find more details about this step in Tetxra documentation. `here <https://textra.readthedocs.io/fr/latest/Documentation/Scripts/4_Pr%C3%A9traitement.html>`_

3.Information Extraction
--------------------------------
Extracts key fields from invoices for further analysis like :
  - Total amount (Tax included)
  - Total amount (Tax excluded)
  - VAT rate
  - Date of invoice
  - Invoice number
  - Supplier Contacts (email, phone, address ...)

4.Categorization
----------------
A critical step in the invoice processing pipeline, where extracted information is analyzed and assigned to the correct accounting categories based on the `Moroccan General Chart of Accounts`. 
This ensures compliance with accounting standards and simplifies reporting.

In general three types of accounts are used :
  - Debit Account
  - Credit Account
  - VAT Account

5.Reporting to the journal book
--------------------------------

What is  journal book ?
+++++++++++++++++++++++
A document that chronologically records all the financial transactions of a company during a given fiscal year.

It allows:

 - Recording all the company's accounting transactions chronologically, both on the credit and debit sides.
 - Organizing the entries for the current fiscal year based on their nature (purchases, sales, treasury, etc.).
