Units of measure and conversions
Work with stock and purchase/make units while preserving the conversion used by each source document, so catalogue edits do not rewrite historical quantities.
Buy in one unit, keep stock in another
A supplier may sell cartons while the warehouse keeps individual units. Products define the stock/sales unit and the purchase/make unit, with the applicable conversion rules. Purchasing and manufacturing use their configured unit; stock availability is compared in stock units. This separates operational quantities from measurements such as package weight or inspection minutes.
Keep the original conversion with the document
A receipt, manufacturing activity or other source-linked child uses the authoritative source's saved conversion. Changing today's catalogue rate does not change what an earlier order meant. Product-specific conversion ownership also supports internal inventory items that do not yet have a finance-product link, preserving their identity if a sales link is added later.
What to know before you start
Configure units before operational use. The system does not guess missing historical conversions or silently revalue old movements using a new rate.
Practical questions
Will changing a conversion fix an old order?
No. Saved documents preserve their original interpretation. Historical inconsistencies need an explicit review rather than a catalogue overwrite.
Are package weights quantity conversions?
No. Package measurements, quality samples and operation durations are different concepts from product quantity units.
Continue the workflow
Inventory product catalogue
Manage stocked products, internal components, purchasing units, tracking choices and costing in an operational catalogue connected to your commercial documents.
Inventory purchase orders
Order inventory from suppliers, keep expected quantities and dates visible, and distinguish what has been received from what has been billed.
Manufacturing orders
Create a manufacturing job for a make-enabled product, release a frozen BOM recipe and track materials, operations and finished quantities through completion.
