Return terms differ by supplier — some give full credit, some part, some only before a cut-off date.

How it is worked out

The stock’s cost is packs × purchase rate. A return in time brings back the supplier’s credit; whatever the credit does not cover is still a loss. If the packs expire on the shelf, the whole cost is lost.

  • Cost = packs × rate
  • Credit = cost × credit %
  • Saved = credit (against expiring on the shelf)

An example

Twelve packs bought at ₹80 each, and the supplier credits 80% of the rate.

  • Cost: ₹960
  • Credit on return: ₹768 — loss ₹192
  • If they expire on the shelf: loss ₹960

Questions

How early should I return near-expiry medicines?

It depends on the supplier — many accept returns only for some time before the expiry date. Keep each supplier’s terms written down and look 90 days ahead every week.

Is GST part of the loss?

GST on the purchase comes back as input credit for a registered shop, so the rate before GST is used here.

How does MedBox24 help with expiry?

The expiry centre lists batches expiring in 30, 60 and 90 days, and a purchase return to the supplier fixes the stock and the supplier’s balance together.
