Batch and expiry on consumables
Sutures, dressings, gloves and disposables carry expiry dates, and expired stock in this category is not merely a write-off but a liability. Recording batch and expiry lets you clear near-dated items in time, respond to a supplier recall, and answer the question an institutional buyer or an inspection will ask. It cannot be reconstructed after the fact.
Institutional accounts and tenders
Hospitals and nursing homes buy against purchase orders and settle on their own cycle, which is slow and document-driven. An invoice carrying their GSTIN, the PO or tender reference, HSN codes and line-wise tax is what gets cleared; anything missing waits another cycle. The delivery record with the receiver's name reconciles against their store.
Equipment, serials and warranty
Monitors, autoclaves and instruments are high-value items under multi-year warranty, and the claim is settled on the serial and date. Recording both on the invoice means a claim is traceable and honoured. Service visits afterwards recorded against the equipment give you a history that is worth real money when the institution replaces or expands.
Credit that runs long
Institutional payment cycles are among the slowest in any trade, which pushes a supplier's working capital out considerably. Ageing rather than totals is what tells you where you stand, credit limits per institution keep the exposure inside what you can carry, and a statement at month end is what their accounts department actually reconciles against.
