Présentation du projet

OCR COMPTA – This web application dedicated to accountants aims to save time in processing invoice binders. It permits :

Extraction of fields (e.g. VAT, Amount including tax, invoice number, etc.) quickly from invoices in image or PDF format
Dynamic management of fields to extract and their patterns
Manage the possibility of having several versions for each field
Manage simple fields and compound fields which are composed of other fields (e.g.; label = No. numFactSupplierName)
View key figures such as field detection success and failure rates for each supplier
Manage customers
Manage suppliers
Manage accounting accounts for each customer
Consult the list of scanned invoices and their fields which have been extracted
Export the result of an OCR to an Excel file
Manage application settings (roles, permissions, users, activity history)
Easily add a new supplier using an interface called ‘Test Lab’
Frontend part to facilitate the addition of a new supplier with its model invoices as well as defining the patterns of each field to extract

Customers

This solution has been saled to several clients in Tunisia, Switzerland and France

Points on technologies

This project is composed of two parts, FrontEnd part developed by Angular 8 , VueJS 3.0 and a BackOffice part developed by Laravel 7. Communication between these two parts is ensured by web services
