🎯 Why ΣEM for your workshop?

Designed by sheet metal and mechanical professionals, for professionals, ΣEM answers the specific challenges of your trade:

🔧 Your activity

• Industrial sheet metal: bending, laser/plasma cutting, punching, welding
• Precision mechanics: turning, milling, grinding
• Mold manufacturing: design, machining, fitting
• Industrial subcontracting: multi-customer management, varied series

💡 Your day-to-day problems solved

Problem	ΣEM Solution
📋 Complex quotes with many operations	Detailed BOMs, machining routings, automatic time/cost calculation
⏱️ Real-time production tracking not possible	Live dashboard, shop-floor time tracking, progress by work order
📦 Raw material management (sheets, bars, tubes)	Stock by dimensions, material traceability, replenishment proposals
🔄 Chaotic shop planning	ASAP scheduling with finite capacity, priority management, machine load
📊 Unclear project profitability	Actual vs. forecast cost tracking, margin analysis per order
🚚 Limited customer/supplier traceability	Full history, attached documents, technical notes

✨ Specialized business features

🏭 Production Module (MES)

• Machining routings: define operations (cutting, bending, welding, machining...)
• Bills of Materials (BOM): raw materials, components, sub-assemblies
• Shop planning: ASAP scheduling with finite capacity, inter-operation delays (global setting or per operation pair, in shop hours), load per machine/work center
• Work orders: automatic generation from quotes
• Production time tracking: real-time tracking by operation
• Quality control: control sheets, non-conformities

🛠️ Tooling

• Press brake punch designer: parametric profile or manufacturer library, bent-part simulation, PDF export, browsable press brake tooling catalog
• Turning tool configurator (ISO 5608 / 6261 / 1832): code assembled step by step, holder ↔ insert compatibility check, optional creation of the matching stock item
• Tool stock: each tool can be linked to the stock item that carries its quantity and minimum

📋 Sales Management

• Detailed quotes: multiple lines, options, variants
• Cost calculation: material + labor + subcontracting
• Opportunity tracking: from lead to delivery
• Order acknowledgments sent to the customer
• Multi-currency and multi-language support
• Customer history: all orders at a glance

📦 Inventory & Procurement

• Dimension-based management: Sheet 2000x1000x3mm, Tube Ø50x3...
• Traceability: batches, serial numbers, material certificates attached to documents
• Stock movements: receipts, issues, transfers, weighted average cost (CUMP)
• Physical inventory: guided counting, valued summary, variance table
• Replenishment: minimum + reserved needs − stock − on order, one draft purchase order per supplier
• Suppliers: pricing, lead times, evaluation

💰 Accounting & Invoicing

• Invoicing: invoices, credit notes, returns
• VAT: multi-rate management
• Payments: settlement tracking
• Analytics: profitability by project, customer, period
• Email: SMTP configured from the application, sending log, PDF attached automatically

👥 Human resources

• Leave balances per employee, leave type and reference period (CP, RTT, time off in lieu...)
• Absence requests with an approval workflow
• Payroll export (CSV / XLSX): absences, clocked hours and production hours per employee, in a neutral format that any payroll software can map
• Skills matrix: authorizations per employee and per machine, with expiry tracking
• Employee file: confidential documents (contract, payslips, certificates) restricted to the employee and HR

🗂️ Document management with built-in CAD viewers

• Unified attachments: products, quotes, orders, delivery notes, invoices, purchases, non-conformities, stock movements, companies and opportunities share one file store
• Private storage: files live outside the web root and are served through authenticated routes
• Viewers loaded on demand (opening a PDF never downloads the 3D engine):
  • 3D meshes: STL, OBJ, PLY, 3MF, glTF (three.js)
  • 3D CAD: STEP, IGES, BREP via OpenCascade compiled to WebAssembly — no server-side converter
  • 2D CAD: DXF, plus PDF, images and spreadsheets

🔧 Maintenance (CMMS) & shop floor

• Maintenance plans and work orders per machine
• Andon alerts: real-time escalation from the shop floor
• Shop reports: booked vs. estimated time, scrap, machine load
• Kanban and GTD boards, Gantt chart, machine load planning
• Nesting: preparation screen by cutting resource, material and thickness — nesting computation available in the commercial edition
• Attendance and energy consumption tracking

✅ Quality, EHS & compliance

• Non-conformities, inspection projects, audit planner, FMEA
• Control device calibration with automatic alerts
• EHS: incidents, risks, trainings, regulatory conformities
• GDPR: soft deletes, activity log, anonymization service, data export and erasure, automatic weekly purge, self-service requests

🔌 Integrations & automation

• Electronic invoicing (French 2026 reform): Factur-X / EN 16931 output, PDP gateway with SUPER PDP and Qonto drivers — invoice issuing and lifecycle tracking, supplier invoice inbox matched against purchase receipts, statuses reported back to suppliers, directory lookup
• FEC export for French accounting
• Nest2Prod: order push and sheet stock synchronization
• LDAP / Active Directory user import
• REST API (Laravel Sanctum) and an integrated AI assistant
• Automatic backups (spatie/laravel-backup) and Laravel Pulse application monitoring

💼 Industry use cases

Example 1: Fine sheet metal workshop

Context: 15 people, bending + laser cutting + welding

ΣEM usage:

• Quotes with detailed routings (laser → deburring → bending → welding)
• Planning across 3 press brakes and 2 lasers

• Real-time tracking of work orders in progress

Goal: faster planning, less dormant stock

Example 2: Precision mechanics

Context: Automotive subcontracting, medium series

ΣEM usage:

• BOMs with certified raw materials
• Machining routings (turning → milling → heat treatment → grinding)
• Integrated quality control (inspection sheets per work order)
• Full traceability from material to finished part

Goal: traceability records ready for an ISO 9001 audit

Example 3: Mold manufacturer

Context: Plastic injection molds, complex projects

ΣEM usage:

• Multi-phase quotes (study, roughing, finishing, trials)
• Subcontracting management (heat treatments, polishing)
• Real-time project profitability tracking
• Centralized technical documentation

Goal: better cost control, on-time delivery

⚙️ Post-Installation Configuration

Important: Before adding lines to a quote, configure:

1. Default VAT: Go to Accounting → VAT and mark an item as default
2. Default Unit: Go to Methods → Units and mark an item as default

Without these settings, you cannot add lines to quotes.

php artisan loadtest:seed	Generate a realistic dataset for load testing. --scale=.	php artisan loadtest:seed --scale=0.5

⏱️ Scheduled tasks & queue

The scheduler (routes/console.php) drives the daily backups (backup:run, backup:clean, backup:monitor), the e-invoicing sync every 15 minutes (wem:pdp:sync), the weekly GDPR purge (rgpd:purge) and the monthly activity-log cleanup. Register it once on the server:

* * * * * php /path/to/artisan schedule:run >> /dev/null 2>&1

On Windows, run php artisan schedule:run every minute from the Task Scheduler, and keep the queue worker alive as a service (NSSM, for example).

A queue worker is required for asynchronous work (emails, integrations, exports):

php artisan queue:work redis --sleep=3 --tries=3

Note: do not run php artisan route:cache — it freezes the locale resolved at cache time and breaks the localized routes.
