A custom ERP replacing a legacy accounting system. Built for a 24-person team in Alexandria. Production since 2026.
Sigma had outgrown its legacy accounting software. The system was server-only, ran on a single PC, and couldn't model the business honestly: separate finance from operations, track maintenance contracts vs new installations, manage a technician fleet, reconcile inter-property bills with the building owners.
The brief was simple: rebuild the entire business OS, multi-user, web-first, in Arabic, modeled on how Sigma actually operates — not on what off-the-shelf software allows.
Each module shipped as a distinct phase. Each phase had its own QA workflow, screenshot record, and team-onboarding session before the next began.
544 customer records imported from legacy. Active vs inactive segmentation.
Maintenance contracts with auto-renewal logic, fee escalation, and payment tracking.
Recurring schedule per elevator, technician assignment, completion logging.
Open ticket queue with priority, age, and SLA tracking. Auto-escalation rules.
WIP tracker per technician. Daily route sheets. Parts requisitions.
New install pricing engine. Standard component codes. Auto-generated PDFs.
QA checklist enforcement before any quotation, work order, or contract closes.
Daily cash ledger. Inter-property settlements. Bank reconciliation.
2.14M EGP outstanding tracking. Aging buckets. Payment reminders.
13-sheet payroll engine. Variable × evaluation %. Disciplinary deductions.
Monthly P&L per division. Owner cockpit dashboard.
Inventory, suppliers, projects, attendance, technician evaluation, commissions, reports …
Arabic RTL throughout. Not a translation layer — the system was designed RTL-first, including charts, tables, and date formats.
Owner-only at first. Then accountant, then ops manager, then technicians. Each role saw only what they needed.
No data loss. 544 customers, 200+ active contracts, 7 years of payment history migrated from legacy with zero gaps.
Owner self-evident. The system explains itself. The owner doesn't need a manual to use it.
Boring tech is a gift. We chose stable, proven tools that we'll still want to maintain in five years.
"What used to take three hours of paperwork takes ten clicks now. The owner sees yesterday's numbers at sunrise." — Internal Sigma feedback, 2026 Q2
