Glossary & Principles for Inventory
Authoritative definitions, accounting conventions, and operational methodology benchmarks.
Reorder Point (ROP)
The predetermined inventory threshold level that triggers a replenishment purchase order to avoid running out of stock during the supplier lead time window.
Landed Cost Calculation
The total all-inclusive cost of acquiring inventory, including the vendor's purchase price, freight shipping, customs duties, import tariffs, insurance, and handling fees.
Bill of Materials (BOM)
A comprehensive, hierarchical list of all raw materials, sub-assemblies, components, and labor routings required to manufacture a finished product.
3-Way Invoice Matching
An internal financial control process that cross-references the vendor's invoice, the internal purchase order (PO), and the receiving report (Goods Receipt Note) before authorizing payment.
Inventory Relational Database Schema & Data Integrity
In Great ERP, Inventory operates on an enterprise-grade normalized relational schema. Unlike disconnected SaaS applications that rely on eventual-consistency REST calls, every transaction executed in Inventory immediately locks dependent records using pessimistic database concurrency control, guaranteeing 100% data consistency across ledgers.
Foreign keys enforce strict referential integrity. Deleting master items or accounts is blocked whenever historical Inventory ledger transactions exist.
Automated event hooks broadcast state modifications to sibling modules in real time, triggering instant inventory reservations and general ledger postings.
Every create, update, or approval action in Inventory logs the operator UUID, before/after values, and client IP for compliance auditing.
Enterprise Deployment & Onboarding Protocol for Inventory
Follow this structured 5-step operational protocol to configure, sanitize, and validate Inventory for production readiness:
Master Data Preparation & Ingestion
Extract and clean historical records from legacy tools. Validate field structures against Great ERP's standardized CSV import templates before staging.
Role-Based Permission Assignment
Configure granular access levels for department members. Define distinct viewer, creator, and managerial approval roles to ensure strict internal control.
Sandbox Simulation & Cross-Module Verification
Process mock transactions in the staging sandbox. Verify that transactions flow accurately into General Ledger accounts, inventory balances, and tax reports.
End-User Operational Certification
Conduct guided workflow walkthroughs with operational staff. Ensure team members can efficiently create records, run reports, and resolve common exceptions.
Production Go-Live & Post-Cutover Auditing
Lock legacy software from further inputs, switch live transaction processing to Inventory, and perform daily closing audits throughout the first month.
