Stock updates automatically as you go about your normal day — billing a sale, recording a purchase, or processing a return all move the number without any extra effort. For everything else (damage, theft, a physical count that doesn’t match), BillBasket gives you a manual stock adjustment with a reason attached, so the ledger stays honest.

​
Understanding the fields

The Inventory screen’s Adjust stock dialog is where you correct a count by hand:
  • Current stock — shown read-only at the top of the dialog so you can see what BillBasket currently believes the count is before you change it.
  • Quantity (+/-) — a signed number: enter a positive number to add stock, a negative number to remove it. This is a change, not a new total — you’re telling BillBasket how much to move the count by, not what the count should become.
  • Reason — a dropdown explaining why you’re adjusting: Correction, Damage, Theft, or Opening stock. This is required so every adjustment leaves a clear audit trail of why stock moved outside of a normal sale or purchase, not just that it did.
Batch-tracked products can’t be adjusted from this dialog — their stock comes from their individual batches/lots, so a blanket manual adjustment would throw off the batch ledger. For those products, correct stock by adding or editing a batch instead.

The Products list’s Current Stock column reflects live inventory — this count went up after a purchase was received and back down after a sale, with no manual step in between.

1

Selling reduces stock automatically

When Suresh bills Meena Devi for a packet of Amul Milk 500ml, its stock count drops by one automatically — no manual update needed.
2

Purchases add stock back

A few days later, Rajesh Sharma records a purchase of Amul Milk from Bansal Wholesale Traders, and the stock count rises to reflect the new delivery.
3

A return adjusts stock too

When Meena returns an unopened Tata Salt packet, BillBasket adds it back to stock as part of processing the return.
4

Check for low-stock warnings

Rajesh opens the Inventory section and sees Parle-G Biscuits flagged as low stock, prompting him to place a fresh order with Bansal Wholesale Traders.
5

Make a manual correction when the count is off

During a physical count, Rajesh finds two fewer packets of Tata Salt than BillBasket shows. He opens Adjust stock for the product, enters “-2” as the quantity, picks “Correction” as the reason, and saves — the stock count and the audit trail both reflect the fix.
