How to do inventory
Counting is the easy part. Trusting the result is the real work.
Doing an inventory count means comparing what physically exists with what the system believes is available. A simple method avoids two extremes: an improvised count nobody knows how to use afterwards, and a fifteen-page procedure that turns three shelves into a military operation.
01
Prepare the scope
Decide what will be counted, in which location and with which unit. A box, one piece and one litre are not interchangeable. Unit ambiguity produces more discrepancies than the arithmetic itself in a surprising number of small inventories.
If the catalogue is large, split it by area or category. Critical products can be verified first while stable references wait for another session. Cycle counting spreads this work without stopping the entire operation.
02
Count physical stock
Count what is actually available, not what should be there according to the last order. Open, damaged, reserved or displaced products need a convention decided before the count so two people can reach the same result.
On mobile, the product record or scanner reduces identification errors. The user enters physical quantity; the system already knows theoretical stock and can calculate the difference. Removing mental subtraction makes the check faster and eliminates an unnecessary source of error.
03
Record discrepancies
When physical quantity differs, correct stock with an inventory movement rather than silently replacing the number. History then preserves the fact that a discrepancy existed and can reveal references that drift repeatedly.
Repeated differences deserve a simple investigation: confusing unit, movement too slow to record, stock spread across locations or users following different routines. The count often reveals the process problem more than it solves it.
04
Use the result
A completed count should lead to a decision. Products under threshold can enter the purchase list, target stock says where to replenish to and coverage helps distinguish a real urgency from a quantity that merely looks small in isolation.
Keep the verification date too. It helps choose the next check according to risk and lets stable products be counted less frequently. The objective is not counting often for its own sake; it is maintaining a quantity reliable enough to act before a stockout.
