Fixit Labs: Device Management & Service Center ERP Platform

Architecting an end-to-end cloud operations and device management platform for electronics repair centers. Unifies intake ticketing, automated technician assignment, parts inventory tracking, and client SMS alerts in real time.

The Problem: Lost Devices, Unsynced Parts & Anxious Clients

Electronics repair businesses and authorized device service facilities face rapid operational complexity. In traditional workshops, repair tickets are noted on paper tags, parts inventory is recorded in disparate spreadsheets, and customers repeatedly call front desks demanding status updates.

Technicians frequently duplicated diagnostics work, misrouted parts across workbench queues, or failed to record warranty claims accurately. Management had no real-time visibility into repair bottlenecks, average diagnostic turnaround, or bench profitability.

"Operational software for service centers must be fast, resilient, and transparent. Every repair stage—from diagnostics intake to component soldering and client handover—demands an unambiguous, traceable state machine." Udara Priyadarshana — Full-Stack Engineer

The Architectural Choice: State-Driven Service Workflows

I engineered Fixit Labs with a clean, domain-driven Laravel backend architecture coupled with a responsive frontend dashboard:

• Strict Ticket State Machine: Every device moves through enforceable lifecycle states: INTAKE -> DIAGNOSING -> AWAITING_APPROVAL -> IN_REPAIR -> QA_TESTED -> READY_FOR_PICKUP. Invalid status leaps are rejected at the API boundary.
• Real-Time Parts Inventory Deduplication: As technicians assign replacement screens, batteries, or microchips to a repair ticket, parts inventory is atomically decremented with low-stock alerts dispatched automatically.
• Automated Omnichannel Customer Alerts: Triggered SMS and email notifications update customers upon diagnosis completion, cost estimates, and pickup readiness, eliminating over 60% of inbound customer check-in calls.
• Multi-Branch Access Control: Strict role-based permissions separating shop floor technicians, store managers, and accounting staff with audit logs on every action.

// Transition Device Repair Status & Dispatch Real-Time Webhook/SMS
public function transitionStatus(RepairTicket $ticket, string $nextState, array $partsUsed = []): TicketResult 
{
    return DB::transaction(function () use ($ticket, $nextState, $partsUsed) {
        // Enforce lifecycle invariant
        $ticket->validateTransition($nextState);

        // Reconcile replacement parts inventory ledger
        foreach ($partsUsed as $partItem) {
            InventoryLedger::deduct($partItem['sku_id'], $partItem['quantity'], $ticket->id);
        }

        $ticket->status = $nextState;
        $ticket->updated_at = now();
        $ticket->save();

        // Fire background notification to client
        event(new TicketStatusUpdatedEvent($ticket));

        return new TicketResult($ticket, true);
    });
}

Measured Outcomes & Business Value

Deployed across multi-location electronics repair facilities, Fixit Labs modernized daily operations:

• 60% Reduction in Inbound Customer Phone Calls: Automated SMS notifications provided end-to-end transparency.
• 35% Faster Repair Turnaround: Technicians gained clear visibility into awaiting diagnostics vs benchwork queues.
• Zero Parts Leakage: Real-time inventory reconciliation ensured every SMD component and display replacement was billed accurately.
