MOQ purchase decision
01

Demand: forecast and orders

02

Inventory: available, inbound, safety

03

Supply: lead time, MOQ, pack

04

Economics: price, freight, holding

05

Risk: stock-out, expiry, cash

MOQ is a constraint, not a target

When net need is 60 and MOQ is 100, buying 100 may create excess while buying none risks service.

Compare consolidation, delay, alternate supply, accepting MOQ, and declining demand on total cost and risk.

Calculate real net requirement

Combine forecast and confirmed orders, subtract usable stock and reliable inbound, then include safety, loss, and lead-time demand.

Blocked, inspection, or uncertain inbound inventory is not automatically available.

Structure supplier constraints

Store MOQ, minimum value, pack multiple, price breaks, lead time, transport lot, shelf life, scope, and effective dates.

Do not leave contract logic only in buyer memory.

Compare complete economics

Balance holding, storage, expiry, and cash against stock-out, expedite, and customer impact.

Scenarios support a buyer; they should not silently approve an irreversible order.

Test boundary products

Use slow, valuable, perishable, seasonal, shared-material, price-break, and delayed-supply cases.

BI0 can be evaluated for purchasing analysis; constraint logic, optimization, approval, and writeback need POC verification.

Make net requirement auditable

A useful formula combines lead-time demand, safety stock, usable inventory, reliable inbound, and committed shortage. Define every status and horizon. Blocked stock and late inbound cannot silently count as available.

Prevent double counting confirmed orders already consumed by the forecast. Show all inputs and versions so a buyer can explain the recommendation.

Version MOQ, pack, and price-break rules

Store supplier, item, plant, currency, MOQ, minimum value, pack and pallet multiples, price breaks, lead time, shipment calendar, shelf life, scope, and effective dates.

Apply MOQ, then pack and order-level constraints, with reasons. Shared minimum value across items requires supplier-order evaluation rather than independent SKU rounding.

Compare complete alternatives and uncertainty

Evaluate early consolidation, supplier-order pooling, delay, alternate supply, substitution, accepting shortage, or declining low-value demand. Include purchase, freight, holding, expiry, cash, expedite, and service effects.

Use conservative, base, and optimistic scenarios where demand or shortage cost is uncertain. The system informs an approval; it should not silently commit an irreversible order.

Use a multi-period inventory trajectory

Extra units can cheaply cover known next-period demand or become obsolete at season end. Simulate through lead time, review period, and lifecycle. A price break is not a saving when surplus cannot be consumed.

Account for transfer time, qualification, and regional restrictions. Enforce quantity conservation and show ending inventory, shortage days, expiry, and peak cash.

Test boundary cases and verify BI0 scope

Exercise zero need, just-below MOQ, pack conflict, short shelf life, delayed inbound, cancellation, shared MOQ, price breaks, and capacity limits. Reconcile quantity and rule explanations in historical replay.

BI0 may support purchasing analysis, while master data, optimization, approval, and ERP writeback require verification. Without reliable demand and inventory state, report conflicts and scenarios rather than a globally optimal order.
