Inventory
Inventory management software that moves with every invoice
JustBill is inventory management software built into your GST billing. Every sales and purchase invoice updates stock on its own, and every movement is logged so you can see where a quantity came from.
- Stock updates on every invoice, return and note
- Godowns, stock transfer notes and a warehouse matrix
- Bill of materials and production orders
- Reorder suggestions from your last 30 days of sales
- Barcode and QR scanning with a scanner or phone camera
How stock moves with every document
In JustBill you don’t update stock by hand after billing. When you save a document, the stock of each product on it changes at once, and a stock movement entry records the quantity, the direction and the document that caused it. Open any item to see its full movement history.
| Document | Effect on stock |
|---|---|
| Sales invoice | Reduces stock |
| Delivery challan | Reduces stock |
| Sales return / credit note | Adds stock back |
| Purchase invoice | Adds stock |
| Purchase return / debit note | Reduces stock |
| Quotation, proforma, purchase order | No change |
Inventory management software features for everyday stock control
Live stock per item
Current quantity, unit and a minimum stock level for each item. Items at or below their minimum show up in the low-stock alert on your dashboard.
Adjustments with approval
Record damage, samples or count differences with a reason. Set a quantity threshold, and larger adjustments wait for an admin to approve them before stock changes.
Item kits
Group items that sell together, such as a gift hamper or a spare-parts set, and add the whole kit to an invoice as separate lines.
Stock and valuation reports
Stock summary, low-stock summary, item-wise sales and purchase, and inventory valuation on FIFO or weighted average cost, with Excel export.
Barcodes and QR labels
Save a barcode on each item, scan it with a USB scanner or your phone camera, and print QR label sheets for products that have no barcode.
Bulk import
Bring in your item list, kits and BOMs from CSV. Item imports report problems row by row, so you can fix the file and upload it again.
Godowns, stock transfers and the warehouse matrix
If you keep goods in more than one place, such as a shop, a back room and a rented godown, create each location as a godown and record how much of each item is kept there.
- Stock transfer notes: move items from one godown to another with a numbered transfer note. JustBill checks that the source godown has enough stock before completing it, and cancelling a completed transfer moves the stock back.
- Transfer PDF: print the note and send it with the goods so the receiving location can check quantities on arrival.
- Warehouse matrix: one grid of items against godowns, so you can see where stock is sitting before you promise a delivery.
Manufacturing with a bill of materials
For small units that assemble or process goods, JustBill links raw materials to finished goods through a bill of materials (BOM). Our manufacturing use case shows how it fits with billing and purchases.
- 1
Define the BOM
Pick the finished item and list each component with the quantity used to make one unit.
- 2
Create a production order
Enter how many units you are making and, if you use godowns, where the run happens.
- 3
Complete the run
JustBill checks every component first. If anything is short, it tells you what is missing and changes nothing. Otherwise it uses up the components and adds the finished goods in one step.
- 4
Keep the record
Each completed run writes a stock movement for every component and an audit log entry, so you can trace how finished stock was produced.
Reorder before shelves go empty
The reorder report compares your current stock with your sales invoices from the last 30 days. It flags an item when stock is at or below its minimum level, or when less than a week of stock is left at the current selling pace.
- Days of cover for each flagged item, most urgent first
- A suggested order quantity of about one month’s demand, topped up to clear any shortfall below the minimum
- Stock, minimum level and 30-day sales side by side, so you can adjust the quantity before ordering
Use the list to raise a purchase order for your supplier. Purchase orders can go through an approval step above an amount you set, and stock comes in when you record the supplier’s purchase invoice.

Frequently asked questions
What is inventory management software?
Inventory management software tracks how much of each product you have, where it is kept and how it moves in and out. In JustBill it is part of your billing, so every GST invoice, return and purchase changes stock without a separate entry. You also get movement history, low-stock alerts and valuation reports.
Does JustBill update stock automatically when I create a GST invoice?
Yes. Saving a sales invoice or delivery challan reduces stock, and a purchase invoice adds to it. Returns and credit or debit notes reverse the quantity, and editing or deleting a document corrects stock as well. Service items are never counted as stock.
Can I track stock in more than one godown or warehouse?
Yes. You can create godowns, record quantities in each and move goods between them with numbered stock transfer notes. The warehouse matrix shows every item against every godown on one screen.
Can I use a barcode scanner with JustBill?
Yes. Save the barcode on the item, then scan it on the POS screen with a USB scanner that types the code and presses Enter, or use your phone camera from the item picker. For products without a barcode, print a QR label sheet from the items list.
How does JustBill value my closing stock?
JustBill has inventory valuation reports on both FIFO and weighted average cost, which you can export to Excel for your CA. Reports are included from the Silver plan upwards.
Can JustBill handle manufacturing with a bill of materials?
Yes. You define a BOM for each finished item, create a production order for the quantity you want and complete it. JustBill checks component stock first and stops the run if anything is short, so production never takes a component below zero.
