SCIerp — Modular Supply Chain, Manufacturing & Accounting ERP.
Experience how a real Enterprise Resource Planning system connects every transaction: create a product, confirm a Purchase Order (increasing incoming stock), post a Goods Receipt (increasing physical stock), confirm and ship a Sales Order, explode a Bill of Materials (BOM) to check component shortages before completing a Manufacturing Order, and verify balanced Double-Entry General Ledger postings.
Inventory & Multi-Warehouse Master (On-Hand, Reserved, Available ATP & Incoming)
Explicit formula convention: Available (ATP) = On-Hand − Reserved. Confirming a Purchase Order increments Incoming; posting a Goods Receipt (GRN) moves units from Incoming to physical On-Hand.
Multi-Warehouse Stock Balances

Manufacturing Orders, BOM Explosion, Component Shortage Gate & Work-Center Capacity
Active BOM Recipe (BOM-NS-500): 1 × NS-BOTTLE-500 requires 1 × NS-BODY-SS + 1 × NS-LID-PP + 1 × NS-SEAL-SIL on Work Center WC-02 Automated Assembly Line (12 run mins/unit + 30 setup mins; 480 available shift mins). Completion is blocked if any component has insufficient unreserved stock.
Manufacturing Orders, Capacity Loading & Component Feasibility Gate
| MO Number | Parent SKU | Build Qty | Work-Center Load | MRP Component Feasibility | Execution Action |

Finance & Immutable Double-Entry General Ledger
✓ Trial Balance Verified: Total Debits == Total CreditsEvery Goods Receipt (GRN), Customer Delivery, Inventory Adjustment, and Manufacturing Order completion automatically posts balanced double-entry journal lines below.

How ERP Connects Demand, Inventory, MRP, Capacity, and Accounting
An Enterprise Resource Planning (ERP) platform is a shared transactional database where operational events and financial records stay synchronized by design. Rather than editing numbers in disconnected spreadsheets, every physical movement passes through a state-controlled workflow:
Confirming a Purchase Order signals expected future supply (increasing Incoming), but cannot be shipped today. Only when the warehouse posts an authorized Goods Receipt Note (GRN) does physical On-Hand stock increase and post Dr Inventory / Cr Accounts Payable.
A Manufacturing Order explodes parent quantity through the Bill of Materials (BOM). If 30 bottles require 30 silicone seals and only 22 seals are available, MRP flags an 8-unit shortage and blocks release until PO-2026-101 is received.
Confirming a Sales Order reserves Available-to-Promise (ATP = On-Hand − Reserved) so the same units cannot be promised twice. Posting delivery deducts physical stock and recognizes both Revenue and Cost of Goods Sold (COGS).
