Item Master Software | Units of Measure
Order in cartons. Invoice in pieces. Post in kilograms.
Primary, secondary and conversion factors per item. The PO uses one unit, the customer invoice another, the books a third. Conversion runs automatically. The audit trail captures the unit at every transaction.

Compliance + integrations
GST invoice in the unit the buyer ordered.
Section 31 + Rule 46 require the unit on the GST invoice. The system supports per-document unit with the conversion documented. The HSN summary uses the primary unit consistently.

Units of Measure FAQ
What buyers ask.
Variable conversion (e.g., a kg of fish has variable piece counts) how is it handled?
Variable conversion is supported per batch. Each receipt captures the actual conversion factor (e.g., this batch has 4.2 pieces per kg). Issues use the batch-specific factor. The audit trail captures the factor per batch.
Our customers order in one unit and we stock in another. Does that break anything?
No, and it is the normal case rather than the awkward one. Purchase in cartons, sell in pieces, hold stock in kilograms: each document uses the unit that makes sense for it, and the conversion is documented on the item so every module reads the same one. What breaks is doing this without a stored conversion, which is how a stock count and a sales report end up disagreeing by a factor of twelve.
Can we change the primary unit after it has been used?
Changing the primary unit retroactively is supported but requires CFO approval and a transition workpaper. The change captures the conversion of historical balances; the audit trail logs the change as a tracked event.
Configure one item with three units. See the documents flow.
Free trial, one item. Set primary, secondary, conversion. Raise a PO in cartons, a GRN in pieces, an invoice in kilograms. Watch the conversion in the audit trail.
