Standardize the material catalog
Assign each material a unique SKU, clear name, unit of measure, category and preferred supplier. Record cost and reorder settings consistently. Avoid duplicate names for the same item, because they split movement history and hide the real available balance.
Maintain a movement ledger
Do not overwrite quantities without context. Record opening balances, receipts, issues, adjustments and corrections as separate movements with dates and users. Current quantity should be the result of that ledger.
Connect consumption to production
Issue material against the work order and, where useful, the technician and workflow step. Save the cost at the time of consumption so later supplier-price changes do not rewrite historical case economics.
- Define who may receive, issue and correct stock
- Block or escalate consumption that exceeds on-hand quantity
- Review low-stock items against upcoming production
- Use purchase-order receiving to create inventory receipts
Review exceptions rather than recounting everything
Use low-stock, out-of-stock, unusual-adjustment and high-consumption views to focus checks. Physical counts still matter, but the movement ledger lets the lab investigate discrepancies instead of starting with no history.
Questions labs ask
Should dental lab inventory use a movement ledger?
Yes. A ledger explains each balance and preserves receipts, issues and corrections.
Why snapshot cost on consumption?
It preserves the material cost associated with the case even if the catalog cost changes later.
