ERP coverage
We work across every major ERP and accounting platform.
Sage, SAP, Dynamics 365, Syspro, NetSuite, Odoo, Xero and more: the ERPs and accounting platforms South African companies actually run, and the global leaders behind them. Your system stays in place. We build the layer around it.

Capabilities
One team from operational problem to production system.
We combine consulting, industrial engineering and software delivery to design the missing layer between your current systems and the way your business needs to operate.
02
Custom CRM
Sales and customer platforms designed around your actual commercial process, not a generic funnel.
03
Management intelligence
Turn fragmented operational data into decision-ready reporting, profitability views and live management visibility.
04
Workflow automation
Automate handovers, approvals, reminders, information capture and repetitive administration across teams.
05
Custom applications
Internal platforms, quotation tools, mobile applications and customer portals engineered around the business.
06
Applied AI
Use AI to accelerate delivery and build practical capabilities such as extraction, summarisation, voice capture and prompts.
Industry focus
Built for businesses where operations are complex and visibility matters.
Our strongest fit is with established organisations that already use ERP or business software but still depend on disconnected processes around it.
Manufacturing & industrial
Production, steel, engineering, mining supply and industrial operations.
Construction & engineering
Project-based organisations, specialist contractors and technical groups.
Field services
Electrical, plumbing, HVAC, compliance and maintenance businesses.
Distribution & logistics
Multi-branch, inventory-led and operationally complex organisations.
Selected systems
See the operational layer, not only the consulting around it.
Three views show the kind of systems MC designs around ERP data and real business processes. The fourth, Luminary, is the live ERP MC built for manufacturing and field service businesses.
Management intelligence
A decision layer over the systems already running the operation.
Connect operational data, cost logic and management reporting in one browser-based platform, without replacing the ERP underneath it.

A product we built and ship
We don't just consult. We build and ship software.
Luminary is the ERP MC built for manufacturing and field service businesses: CRM, quoting, work orders, scheduling, job cards, stock, purchasing, invoicing and live profit per job, on one login, for companies that have outgrown spreadsheets but do not belong on enterprise ERP.
Sold via Luminary Software (Pty) Ltd. Available at luminarysystems.co.za
Quote to cash on one record
Pipeline, work orders, purchasing and invoicing share the same customer, job and stock records. Nothing is retyped.
Built for the floor and the field
Scheduling, timesheets and job cards designed for crews in vehicles and teams on the shop floor, not consultants at desks.
Profit visible per job
Labour, purchase orders and hours roll up into gross profit per job and department on true cost, before the month closes.
Sits beside your accounts
Invoices sync to Sage, Xero or Pastel, so the books always agree with what happened on site.

Speed without shortcuts
Move rapidly from business problem to working system.
Faster prototyping and development mean more time can be spent validating the solution with real users and improving the parts that create operational value.
Built to evolve
A long-term systems partner, not a once-off software handover.
We design for iteration, adoption and expansion so the platform can continue evolving alongside the company, its people and its data.
