Custom PrestaShop Module for Bangla ecommerce

Project Title:
Custom PrestaShop 8.2 Module Development (Bangla Search, Courier API, POS Sync, Advance Payment)

Project Description:

Hello,

I own an ecommerce robotics & electronics store (BigyanProject.com) running on PrestaShop 8.2 (PHP 8, MySQL, cPanel hosting).

I am NOT looking for theme customization or design work.

I need an experienced PrestaShop module developer to build a NEW custom module for my business workflow. This module will solve Bangla language issues and add courier, customer tracking and POS integration features.

This is a backend development project.

CORE FEATURES REQUIRED

1. Bangla Product Search Fix
Currently PrestaShop search does not match Bangla keywords properly.

Example:
If a customer searches a Bangla product name, correct products are not found.

Developer must:

* Fix search indexing for Bangla
* Proper UTF-8 / Unicode handling
* MySQL collation correction if necessary
* Accurate Bangla keyword search results

---

2. Bangla PDF Invoice Fix
My invoices generate broken Bangla text.

Problems:

* Font missing
* Characters overlapping
* Boxes showing instead of Bangla letters

Required:

* Implement Bangla compatible PDF (mPDF or similar)
* Embed Bangla font
* Fully readable Bangla invoice for customers

---

3. Customer Tracking by Phone Number
Currently PrestaShop identifies customers by email/order ID only.

I need:

* Search orders using phone number
* View all previous orders of that phone
* Customer history panel in admin order page

---

4. Customer Behavior Check (Courier API)
In Bangladesh, courier services provide delivery behavior data.

Module must:

* Send phone number to courier API
* Show customer risk / return history
* Visible inside order admin panel

(Couriers: Pathao / Steadfast / Paperfly or similar)

5. One-Click Courier Booking
Inside each order page I want a button:

"Create Shipment"

Click → automatically create parcel in courier website using API.

No manual typing in courier panel.

---

6. POS / Stock Sync Module
I use a separate POS/stock software.

I need middleware synchronization:

PrestaShop → POS
orders
customers
address
status

POS → PrestaShop
products
categories
stock quantity
price

Automatic sync (API + cron/webhook).

---

7. Advance Payment Feature
I need partial payment support.

Example:
Product price = 1000
Customer pays advance = 100
Remaining due = 900

Admin must be able to:

* Enter advance amount
* Record due amount
* Show due in order
* Update after delivery payment

Developer must be experienced in:

* PrestaShop module development

* MySQL
