The operating system for workshops.
Slabs OS runs the whole workshop — customers, jobs, quoting, invoicing — one system, built on Linux. The core is free forever. You only pay for modules you actually use.
The model
Free core. Fair modules. No lock-in.
Workshop software shouldn't cost a monthly ransom before it earns you a cent. The core handles the daily essentials — free, forever, any workshop size. Modules add on when you need them.
Customers & CRM
Customer records, contact history, vehicle and machine notes, reminders.
Jobs & job cards
Intake to handover: statuses, checklists, photos, technician notes.
Quoting & invoicing
Quotes that convert to jobs and invoices. VAT-ready, PDF output.
Inventory & parts
Stock levels, supplier lists, low-stock alerts, cost tracking.
Notifications
Job-ready SMS, WhatsApp and email notifications, follow-ups.
Reporting
Revenue, turnaround times, technician hours, parts margins.
Booking calendar & payments
Public booking page, PayFast/Yoco links on invoices, deposits.
Multi-branch
Multiple workshops, one OS instance, consolidated reporting.
No lock-in
Standard formats, documented backups, export everything. Your data leaves with you.
