Inventory management you can actually trust
Inventory problems rarely look like inventory problems at first. They show up as late orders, emergency purchases, a stocktake adjustment that wipes out a month's profit, or customer service promising stock that is not there.
Overview
Why this area matters
Inside an ERP, inventory is connected to purchasing, sales, manufacturing and accounting, so every movement has a cause and a financial effect. Getting the design right — locations, units, tracking and valuation — is what makes it reliable.
01Typical problems
Signs the current setup has run out of road
01
System stock ≠ shelf stock
Counts regularly disagree with the system, so nobody trusts availability.
02
Excess and shortages together
Cash tied up in slow movers while fast movers run out.
03
Valuation surprises
Inventory value on the balance sheet does not match operational reports.
04
No traceability
Cannot tell which lot went to which customer.
02Capabilities
What a well-built setup includes
01
Multi-location stock
Warehouses, zones and bins with real-time quantities and reservations.
02
Lots and serials
Traceability with expiry dates, removal strategies and genealogy.
03
Units of measure
Buy in cases, store in packs, sell in units with exact conversions.
04
Replenishment rules
Min/max, make-to-order and multi-warehouse resupply.
05
Cycle counting
Scheduled counts by ABC class or location with controlled adjustments.
06
Perpetual valuation
FIFO, average or standard cost with automatic accounting entries.
03Workflow
How the process runs end to end
- 01

04 — Technical notes
Design decisions worth getting right
Inventory is modelled as moves between locations, including virtual locations for suppliers, customers, production and scrap. This makes every quantity change traceable and lets the accounting impact be calculated consistently.
Costing method is chosen per product category and should be agreed with finance before go-live. Changing it later requires revaluation and creates reconciliation work, so we treat it as a design decision rather than a setting.
