VitrioKnow what is ready to use.
Quantity is only useful when the lot is usable. Expired and quarantined stock stays out of this example’s available balance.
Completed activity becomes reagent usage.
Ten completed runs, using 0.30 mL each, consume 3.00 mL from the eligible lot. Replaying the same event cannot deduct it twice.
A stock decision becomes a clear request.
This example requests 23.00 mL at ₦2.00 per mL: ₦46.00 before additional costs. A draft request does not increase stock or commit a purchase.
Two responsibilities. Two recorded decisions.
Real approvers use their own authenticated accounts. This preview shows an already-reviewed example; it cannot approve or send an actual order.
Stock changes when goods are accepted.
The example delivery adds 23.00 mL once. Creating an order never counted it as stock. A receipt stays linked to its lot and purchase order.
Check the invoice against the evidence.
Compare what was ordered, accepted and invoiced. A successful match supports a finance review; it does not transfer any money.
