|Most businesses will use several units of measure at some time or the other.
Take purchases –you can order in the units you are comfortable with and receive goods in a different unit - for e.g., order in Pcs, receive in Kgs. Similarly you could record sales in the units that your customer is comfortable with. This flexible ‘compound’ unit of measures ensures that Tally.ERP 9 does not impede your way of working.
Some commodities like cotton, have 'peculiar' problems –the unit of stock often used is 'bales', yet trade is in Kgs. With changes in weather, cotton loses or gains weight due to changes in moisture content. If you used Kgs for your records, you would lose the ability to manage stock count and stock take of bales; if you used bales, you would have a mismatch in the actual quantity transacted. This problem is compounded in real life since each bale carries a different weight of cotton.
With Tally.ERP 9 you can manage all these by recording both Kgs and bales in transactions at the same time. Stock valuation will be done in Kgs; inventory count can be managed in bales!
You receive some supplies –the Invoice shows 5 Pcs. and the actual count shows 6 Pcs.! Were you to enter your receipt as 6 Pcs., there will be a mismatch between the voucher and physical document, resulting in an audit objection. Entering 5 Pcs. would mean that one piece is not recorded. Tally.ERP 9 supports 'actual' and 'billed' quantities, thus de-linking the inventory count from the financial impact of the transaction. With this you can also receive and deliver free samples and manage the variations that occur now and then.
Therefore compound units, alternate units and billed/actual quantities should deliver the capabilities needed for most, if not all, of your requirements.
