### System Overview
From your description, I understand that you're outlining a web-based management system for Masunzu Bar Hotel, a company specializing in wholesale distribution of alcoholic beverages (primarily sold in crates for wholesale, but with options for individual bottles for tasting or sampling). The system handles inventory, sales, expenses, requisitions, and user roles across multiple provinces in what appears to be Burundi (based on mentioned provinces: Bujumbura, Ngozi, and Gitega). It's designed to track operations efficiently, ensure accountability through approvals, and maintain separate stocks and pricing for wholesale and retail.

Key technical specs:
- **Backend**: Built with PHP and MySQL.
- **Development Environment**: XAMPP on Linux (Debian 13) with GNOME desktop.
- **Language Support**: Starts in English, with a toggle to switch to French (likely via session-based language selection or user preferences).
- **Auditing and Security**: Tracks all user actions, including login/logout history (e.g., via a logs table in the database). Real-time history for requisitions and expenses, probably displayed in dashboards or reports.

### Core Features
#### 1. **Inventory and Stock Management**
   - **Per-Province Structure**: Each province (e.g., Bujumbura, Ngozi, Gitega) has two distinct stock types:
     - Wholesale stock (for crate sales to bulk buyers).
     - Retail stock (for individual bottle sales, e.g., for tasting).
   - **Pricing**: Separate pricing for wholesale and retail products. Prices can be assigned per product, per stock type, and possibly per province.
   - **Suppliers**: Varied suppliers for beverages; the system should track supplier details, purchases, and link them to stock entries.
   - **Stock Distribution**: Operation Manager distributes beer stocks from a central point to provincial stocks. Stock Managers in each province receive and manage these.
   - **Monitoring**: Procurement Manager oversees overall stocks, including expiration dates (e.g., alerts for expiring products).

#### 2. **Sales and Orders**
   - **Order Process**:
     - Marketing Agents recruit clients, place orders on their behalf.
     - Orders entered into the system by agents.
     - Provincial Stock Manager approves the order.
     - Approved orders forwarded to the Operation Manager for fulfillment (e.g., distributing from central stock).
   - **Payment and Visibility**:
     - Approved orders (by Stock Manager and Operation Manager) appear in Cashiers' menus with status: Paid or Unpaid.
     - Credit sales require validation by DG and/or DGA.
   - **Invoices**: For every expense or sale, the system generates invoices. Stock Managers have a dedicated menu to fill invoice forms based on orders/commands.

#### 3. **Expenses and Requisitions**
   - **Requisition Workflow**:
     - Any user can initiate a requisition via their menu.
     - Form includes: Department name, User's name and position, List of reasons/motifs with corresponding amounts, Auto-calculated total amount.
     - Status starts as "Pending Validation."
     - Sent to provincial Stock Manager for first validation (V1).
     - After V1, automatically forwarded to both DGA and DG simultaneously.
     - Validation by either DGA or DG finalizes it.
     - Approved requisition becomes available to Cashiers in the same province as the initiator.
   - **Payment Process**:
     - All outgoing money (expenses) must follow this requisition schema.
     - Cashier handles payment, assigns a receipt number, and requires a signature from the recipient.
   - **Tracking**: Real-time historical logs of all requisitions and expenses (e.g., a dashboard showing timelines, statuses, and details).

#### 4. **User Roles and Permissions**
   Based on the roles you listed, the system needs a role-based access control (RBAC) system, likely implemented via user types in the database with associated permissions. Here's how I map them:
   - **Board of Directors (Conseil d’administration)**: Likely oversight/view-only access, no daily operations.
   - **Director General (DG)**: Also acts as DAF (Director of Administration and Finance). Approves expenses, requisitions, credit sales. Top-level approvals.
   - **Deputy Director General (DGA)**: Similar to DG, shares approval duties for expenses, requisitions, and credit sales. Can create Accountants, subject to DG approval.
   - **Procurement Manager**: Monitors stocks company-wide, tracks expirations, possibly handles supplier purchases.
   - **Operation Manager (Chef de Département Operation)**: Distributes stocks to provinces, receives and processes orders from Marketing Agents.
   - **Finance and Accounting Head (Chef Département Finance et Comptabilité)**: Manages overall company accounting, possibly generates reports across all provinces.
   - **Marketing Head (Chef de Département Marketing)**: Oversees client acquisition and order management.
   - **Stock Managers (Gestionnaires de Stocks)**: One per province (initially 3: Bujumbura, Ngozi, Gitega; scalable to more). Receive stocks from Operation Manager, approve agent orders, handle invoices, perform V1 on requisitions.
   - **Accountants (Comptables)**: Per point of sale/province. Created by DGA, approved by DG. Handle financial records locally.
   - **Marketing Agents**: Recruit clients, enter orders into the system for approval.

   - **Scalability**: Ability to add more Stock Managers/points of sale as needed.
   - **Cashiers**: Not explicitly a role, but implied; they handle payments, view approved orders/requisitions, and issue numbered receipts. Likely tied to provinces.

### Potential Implementation Notes (Based on Understanding)
- **Database Structure**: MySQL tables for users (with roles, provinces), stocks (per province, per type), products (with prices, suppliers, expirations), orders, requisitions (with statuses, approvals, histories), invoices, logs (actions, logins), etc.
- **Frontend**: PHP-based interface with forms for requisitions, invoices, etc. Dashboards for histories. Language switching could use PHP sessions or GET parameters.
- **Workflow Automation**: Use PHP to handle email notifications or in-app alerts for approvals (e.g., after V1, auto-notify DGA/DG).
- **Security**: Session management for logins, audit trails for all actions.
- **Reports**: Real-time views for histories, possibly with filters by province, date, or user.

If this matches your vision, great! If I've misunderstood any part (e.g., specific workflows or roles), could you clarify so I can refine it? If you want, I can help brainstorm database schemas, PHP code snippets, or next steps for development.

    Module Development Order
To ensure we build the system step-by-step, here’s a proposed order for developing the modules, based on their dependencies and importance to the system’s functionality:

Login/Auth System (Current, in progress)

Files: config/database.php, includes/auth.php, includes/functions.php, modules/login/login.php, modules/login/logout.php
Status: You’ve copied the files; ready for testing.
Why: Foundation for user access and role-based redirects.


User Management

Files: modules/users/manage.php, modules/users/profile.php
Why: Allows DGA/DG to create users (e.g., Operation Manager, Cashiers), needed for testing other modules with multiple users.
Features: User CRUD, role/province assignment, approval workflow.


Operation Manager (New)

Files: modules/operation/orders.php, modules/operation/distribution.php, modules/operation/history.php
Why: Placed here because it depends on users (to assign Operation Manager role) but is a prerequisite for Sales/Orders (since they approve orders). It also interacts with Inventory for stock distribution, but we can implement basic distribution without full inventory functionality.
Features: Approve Marketing Agent orders, distribute stocks to provinces, view distribution/order history.


Requisitions

Files: modules/requisitions/create.php, modules/requisitions/approve.php, modules/requisitions/history.php
Why: Core expense workflow, independent of Sales/Inventory but relies on users (for requesters/approvers).


Cashiers

Files: modules/cashiers/operations.php, modules/cashiers/balance.php, modules/cashiers/history.php, modules/cashiers/reports.php
Why: Depends on Requisitions (for payments) and Sales (for order payments).


Sales/Orders

Files: modules/sales/orders.php, modules/sales/invoices.php, modules/sales/credit.php
Why: Depends on Operation Manager (for order approvals) and Inventory (for stock checks).


Inventory

Files: modules/inventory/stock.php, modules/inventory/suppliers.php, modules/inventory/expiration.php
Why: Supports Sales and Operation Manager by managing stock levels.


Expenses

Files: modules/expenses/payments.php, modules/expenses/receipts.php
Why: Complements Requisitions and Cashiers, can be built after core workflows.


Reports

Files: modules/reports/finance.php, modules/reports/analytics.php
Why: Relies on data from all modules for summaries.


Dashboards

Files: dashboards/*.php (e.g., operation_dashboard.php, cashier_dashboard.php)
Why: Built last to integrate all modules into role-specific views.



Rationale for Operation Manager Placement:

Placed after User Management to ensure Operation Manager users can be created.
Placed before Sales/Orders because the Operation Manager approves orders, making it a dependency.
Placed before Inventory since basic stock distribution can be implemented with minimal inventory functionality (e.g., update stock table quantities), while full inventory management (suppliers, expirations) can come later.


#colors 


   - Branding and Visual Design:
     - Use the Masunzu Bar Hotel color palette for a premium, beautiful look:
       - Dark Brown/Sepia (#4B2F1F, ~40-45%): Dominant background for headers, footers, or main containers.
       - Bright Orange/Gold (#F4A261, ~35-40%): Primary accent for buttons, links, highlights.
       - Off-White/Cream (#F4F0E4, ~10-15%): Background for content areas to ensure readability.
       - Black (#000000, ~5-10%): Outlines, borders, and secondary text.
     - Modern and Beautiful: Employ CSS Grid/Flexbox for layouts, sans-serif fonts (e.g., system defaults like Arial or Roboto via Google Fonts if lightweight), subtle shadows/transitions for interactivity without heavy JS. Keep it minimalistic: No unnecessary images/icons, compress assets, avoid bloat.





     each province should have its own stock ,so that whenever reception is done , their stock increases ,

a sent and received stock should have an id so that in history it should be viewable in grouped for example in history i should see a stock sent (total amount, and other relevant information)plus a button to view details of the stock sent :products , quantity per product, this is different from what we have now as the history shows history or products for example a stock make of 5 products , in the history these products are listed separately , also the history should also be able to filter by status , province  







###  on operation dashboard lets make this changes . first the operation manager has the right to create new products( all information needed , name , volume , supplier crate quantilty , expiration date , whole sale price, retail price ,etc) and also he is the only one who adds products in the main stock, products has to be in the main stock before he send them into their destination provinces , destination provinces stocks are impacted by the transfert when the transfert has been approved by the stock manager in that province , and when the stock manager in a province has approved reception of stock , the stock manager in that province can now dispatch the stock into the retail and detail stock, by logic the province has to decrease to increse the detail and retail stock , you get it ?? this means there have to extra pages to implement this right ?


#  important validation questions,
make sure on adding to main stock , the systems validate that the number inserted is divisable by the number of bottles in one crate eg:
a product with 12 botles/crate, this products are bought in crates and half crates 


#low stock alert ifatire kuri 10 botles 
code imeze uku : iri muri stock_manager_dashboard.php hama code ni iyi : 
if ($stock['province_quantity'] < 10 || $stock['wholesale_quantity'] < 10 || $stock['retail_quantity'] < 10) {
    $low_stock[] = $stock;
}



generate cash_statement.php and tell me where to put it 
also redo this files based on existing one please!
deposit.php
pay_requisitions.php
and receive_cash.php





perfect , now from that version , check that the total amount does not exceed remaining loan baance, if yes notify the user
