How the AI Assistant Works

At the bottom-right corner of every screen in CorruPack, you will find the floating AI Copilot button. It acts as your 24/7 business analyst, connected directly to your live database.

  • Roman Urdu & English Understanding: You can type in everyday factory language (e.g. "Ravi ka balance kitna hai" or "Show me 24 inch ATL reels").
  • Live Grounding: The bot does not hallucinate — it runs secure SQL queries in the background and returns exact numbers from your live registers.
  • Quick Action Chips: Click the pre-made suggestion chips at the top of the chat to run instant reports in 1 click.
Practical Query Examples:
๐Ÿ’ฐ Accounts & Udhari:

  • "Who owes more than Rs. 50,000?"
  • "60 days se ooper walay customer batao"

  • "24 inch ATL reel kitni bachi hain?"
  • "Total corrugated roll stock summary"
  • "Zombie reels jo 60 din se use nahi huin"
๐Ÿ“ฆ Corrugated Carton Manufacturing Engine (Core)

Corrugator sets (Reel to Roll), 3/5/7-ply pasting, rotary cutting, and box stitching

1. Corrugation Batch (Reel → 2-Ply Roll)

The first physical stage of box manufacturing: feeding paper reels into the corrugator machine:

  • Select Face Reel: The smooth outer paper liner (e.g. Kraft 150 GSM).
  • Select Fluting Reel: The inner paper that gets formed into wave arches (e.g. Semi-Kraft 120 GSM).
  • Flute Profile: Select A-Flute (thick cushioning), B-Flute (standard carton), or E-Flute (micro-flute for consumer boxes).
  • Cost Per Inch Calculation: The system calculates your live manufacturing cost per inch based on reel purchase rates and weight consumed.
  • Output: Generates fresh Roll Stock ready for sheet cutting.
2. Corrugated Sheet Making (Roll → Sheet)

Converting 2-ply rolls into flat 3-ply, 5-ply, or 7-ply sheets for box conversion:

  • Pick available 2-ply roll from stock → Enter target sheet dimensions (Length × Width in inches).
  • Roll weight is deducted, and finished cut sheets are added to Corrugated Sheet Stock.
3. Box Slotting, Creasing & Stitching / Gluing

Passing cut corrugated sheets through the rotary slotter and stitching machine to produce finished, flat-packed cartons ready for dispatch.

๐Ÿ“œ Paper Reel Stock & Warehouse Tracking

Manage raw paper reels by GSM, BF, Mill Supplier, Weight, and Godown location

Reel Inventory & Filtering

Every paper reel received from mills is tracked individually with its own Reel ID:

  • Filters: Filter by Paper Grade (Kraft, Test, Semi-Craft, White Top), GSM (100 to 250), Size (24" to 60"), and Godown location.
  • Zombie Stock Filter: Instantly highlights paper reels sitting in your warehouse for more than 60 days without consumption, helping you free up locked cash flow.
  • Reel Lifecycle Flow: Click on any Reel ID to see its complete journey: Purchase date, supplier rate, corrugation sets where it was consumed, and remaining balance weight.
๐ŸŒ€ Corrugated Roll & Sheet Stock

2-Ply roll inventory and cut sheet inventory by dimensions (Length × Width)

Roll Stock

Displays all manufactured 2-ply rolls in stock with their width (inches), quality grade, flute type, and production cost value.

Corrugated Sheet Stock

๐Ÿ“ Sales Orders (Customer PO Management)

Track carton orders from PO creation to partial dispatches and delivery completion

Creating a Sales Order (PO)

When a client orders custom corrugated cartons:

  • Select Customer → Enter Customer PO Number and Delivery Deadline.

  • The order is saved with status Pending and visual progress bar showing 0% Dispatched.
๐Ÿšš Delivery Challans (DC Gate Pass)

Dispatch cartons, handle partial truckloads, and print driver gate passes

Generating a Delivery Challan
  • Open the pending PO → Click Create DC.
  • Partial Dispatch: If the order is for 10,000 cartons and your truck carries 4,000, dispatch 4,000. The remaining 6,000 remains pending on the order.
  • Stock Deduction: Finished cartons are automatically deducted from sheet stock, and an official printable Delivery Challan is generated for the driver.
