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.
GSTN UQC list. Are all our units mapped?
Yes. The system maps your internal units to the GSTN UQC list (NOS for pieces, KGS for kilograms, LTR for litres, etc.) automatically. Where a UQC mapping is uncertain, the tax reviewer is flagged at item creation.
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.
