Operational CRM & Dispatch
Real-Time Dispatch: < 0.2s Routing
01 / Problem & Constraints

Manual Dispatch Overhead & High-Latency Job Allocation

A commercial field service company managing dozens of mobile technician units operated across fragmented legacy software, paper dispatch logs, and manual phone calls. As service volume grew, delayed technician routing caused customer dissatisfaction, overlapping assignments, and severe invoicing delays.

Constraint 01

Manual telephone dispatching creating 30-45 minute operational delays per emergency call

Constraint 02

Disconnected legacy ERP software unable to provide real-time field technician status

Constraint 03

Lack of automated customer notifications resulting in heavy inbound support call volume

Constraint 04

Double-entry bookkeeping required to reconcile completed service tickets into billing systems

02 / Architectural Approach

Centralized Real-Time Command Center with Bi-Directional ERP Sync

Infynic engineered a centralized dispatch operating system. Field requests are ingested automatically, mapped geographically, and assigned to qualified technicians based on real-time availability. Field updates sync back to corporate dispatch boards via WebSockets and reconcile automatically with legacy ERP databases.

SYSTEM EXECUTION FLOW
Inbound Dispatch Ingestion → Geo-Proximity Matcher → Technician App → Legacy ERP Sync
[01]

JOB INGESTION

Service requests are ingested via web portals, customer hotlines, and commercial partner APIs.

[02]

GEO-PROXIMITY ASSIGNMENT

PostGIS spatial algorithms match job coordinates to active technician geofences and skillsets.

[03]

REAL-TIME FIELD TELEMETRY

WebSocket streams broadcast job acceptance, travel progress, and job completion events.

[04]

ERP SYNCHRONIZATION

Asynchronous worker queues transform completed job summaries into legacy ERP ledger entries.

Key Architectural Decisions & Rationale

DECISION 01

PostgreSQL with PostGIS Spatial Indexing

Enables microsecond spatial queries to calculate technician proximity and estimated arrival windows.

DECISION 02

Decoupled Asynchronous ERP Integration Bridge

Isolates the modern real-time dispatch interface from legacy ERP downtime or slow relational queries.

DECISION 03

WebSocket Stream with HTTP Polling Fallback

Provides instant updates to dispatchers while ensuring reliable connectivity for technicians in low-signal areas.
