1. The Hybrid Edge-to-Cloud Architecture

Zero Internet Dependency

Pure-cloud software grinds to a halt the moment fibre drops. Legacy on-premise software dies when a physical server fails. NexusERP eliminates both single points of failure.

2. Specialist Trade, Estimation & Manufacturing

Built for Yards & Merchants

Standard retail systems struggle with millimeter dimensions, sheet cutting waste, building plan take-offs, and in-house manufactured assemblies. NexusERP embeds specialist calculators directly into the quotation and inventory pipeline.

MODULE: EST-TAKEOFF

Building Plan Quantity Estimator

Turns architectural dimensions (Walls, Strip Foundations, Slabs, Rooms, Openings, Drywall, Ceilings, Paint, Tiling, Sanware Kits & Roofs) into itemized POS Quotations. Features a Two-Tier SKU Map so multiple salespeople can customize project brands or clone budget alternatives without cross-user collisions, plus automatic truck-load weight calculation.

MODULE: GLS-JOBCARD

Glass Calculator & Cutting Jobcards

Calculates exact pane areas (m²) from millimeter measurements across 15+ glass and mirror profiles, auto-calculates perimeter glazing putty (kg), groups cuts by SKU onto a formal quote, and prints a version-controlled Workshop Cutting Jobcard (v1, v2, v3) that tracks every dimension revision.

MODULE: MFG-BOM

Manufactured Items (Sum-of-Parts BOM)

Build custom in-house products (e.g. picnic benches, pre-hung doors, truss kits) from a Bill of Materials plus labour. Whenever a raw component (timber, screws, glue) increases in cost via GRV or import, NexusERP alerts management to either auto-update selling prices or absorb the variance into profit.

MODULE: POS-OMNI

Omni-Channel Counter & Yard POS

Auto-detects desktop terminals vs. mobile tablets. Enforces real-time debtor credit limits, spawns automatic Buyout Logs and Client Requisitions when ordered quantities exceed stock on hand, and protects floor margins with instant Supervisor PIN price-override verification.

3. 5-Tab Master Data Hub & Cost-Blind Security

Strict Counter Margin Protection

Every screen in NexusERP is governed by a Deny-by-Default Role-Based Access Control (RBAC) engine. Counter sales staff can quote and invoice across four customer price tiers (Tier 1 Retail, Tier 2 Trade, Tier 3 Bulk, Tier 4 Contract/Cost+) while remaining 100% blind to wholesale unit costs and gross profit percentages—which are stripped directly at the database query layer unless the user's security profile holds explicit financial clearance.

Interactive 4-Tier Matrix & 2-Way Shopify Sync

Authorized buyers manage products inside a unified 5-Tab Master Data Hub featuring a live Bidirectional 4-Tier Pricing Matrix. Web-active items sync to Shopify in the background with a Dual-Threshold Safety Buffer that reserves floor stock for walk-in trade before online orders can deplete inventory.

4. Double-Entry Financial Core & Supply Chain

Zero External Sync Fragility

NexusERP eliminates fragile third-party accounting bridges by operating its own native Double-Entry General Ledger, Chart of Accounts, Bank Reconciliation, Cashup, VAT Control (Account 2100), and Debtor/Creditor Sub-Ledgers.

Automated Operational & General Ledger Posting Matrix Real-Time Double-Entry
Operational Event Automated Operational & Stock Action Real-Time General Ledger Posting
POS Tax Invoice & Tender Deducts Stock on Hand (SOH), verifies debtor credit limit, logs hardware terminal & cashier session. Cr Revenue, Cr Output VAT (15%), Dr POS Clearing / Debtor Control, Dr COGS, Cr Inventory Asset.
Credit Note / RMA Return Restores SOH to warehouse bin, applies optional restocking fee, links to original invoice number. Dr Sales Returns, Dr Output VAT Reversal, Cr Debtor Account / Cash Clearing.
Supplier GRV & Freight Waybill Updates SOH, apportions 3rd-party courier freight into landed unit cost, queues ZPL shelf labels. Dr Inventory Asset, Dr Input VAT, Cr Accounts Payable Control (Supplier & Freight Creditor).
Merchandising Sign-Off & Claims Mobile floor verification of received GRVs; variances auto-spawn priced Supplier Claims. Flags GRV discrepancy value and blocks duplicate supplier invoice capture.
Return to Supplier (RTS) Deducts returned stock, enforces anti-fraud check against double-reversal of historical GRVs. Dr Creditor Sub-Ledger Balance, issues official numbered Debit Note.
Smart Procurement Queue Monitors Min/Max levels, Shopify safety buffers, and floor staff restock requests to auto-build POs. Tracks committed Purchase Order liability from Draft to Issued and Completed.
5. Biometric Workforce, Payroll & WMS Dispatch

32-Day Payroll Recovery Calculator

NexusERP integrates directly with Hikvision facial recognition and fingerprint terminals, pooling infinite daily punches per employee. It enforces configurable grace buffers (e.g., 20-minute early / 15-minute late no-pay windows), auto-offsets short time, and caps unauthorized overtime—typically recovering its entire software cost in 32 days.

6. Multi-Company & Corporate Multi-Branch Scale

Master-Tenant Isolation

Each company or branch operates in its own isolated database space—preventing ID collisions and ensuring that a sub-branch never goes offline if Head Office loses connectivity.
