Bespoke Field Service Automation: How We Built Servexa CRM for Seamless Dispatch & GMB Reviews

For modern local service agencies—whether dealing with security installations, HVAC servicing, network setup, or plumbing—manual tracking is a major bottleneck. Managing technicians over phone calls, copy-pasting customer details into raw Google Sheets, and tracking down payments manually wastes hours daily. Furthermore, using generic SaaS CRM products (like Salesforce or Zoho) incurs heavy per-user monthly subscription fees and doesn't support field service workflows natively. The solution is Custom CRM Development. By building a bespoke web application tailored to your exact operations, you obtain role-based access, lifetime free setups, and seamless third-party API integrations. In this case study, we walk through the design of Servexa CRM, a custom field operations CRM engineered by Ashish Kumawat to streamline technician routing and automate Google reviews.

1. The Technician mobile View: Direct dispatching in the Field

One of the biggest leaks in service operations is poor field communication. Technicians receive incomplete addresses or client details via WhatsApp groups, leading to delays. In Servexa CRM, we solved this by designing a mobile-first, simplified Technician Portal. When an admin assigns a ticket, the technician (e.g. Amit Sharma) sees only their active pending jobs. The card shows essential details: Customer Name (e.g., Ashish Kumawat), direct contact triggers, service requirements (e.g., CCTV Installation), and Google Maps coordinates for direct navigation. Once finished, the tech writes a quick completion note, uploads verification photos, and marks it done, instantly removing it from their list and notifying the admin:

2. The Admin Dispatch Hub & Job Sheets Management

For business owners and managers, keeping track of multi-technician schedules is chaotic. The Admin Dashboard in Servexa CRM introduces a structured Job Sheets & Assignments manager. Admins can create a ticket via a simple '+ New Job Assignment' form, specify priority (High/Medium/Low), input client location details, set estimated quotes, and allocate the ticket to a specific technician from their squad. The grid lists jobs filtered by status (All, Pending, In Progress, Completed), allowing admins to audit progress and trigger invoices in seconds once jobs are marked completed by field staff:

3. Auditing Technician Performance & Quality Control

To maintain high service quality standards, admins need visibility into individual performance. The Squad Manager dashboard displays detailed metrics for each technician, including active vs. completed jobs and the total sales revenue generated. Admins can open a technician's performance card to review their entire history audit, showing exact timestamps, written completion reports, and uploaded photos of the completed field installation. This ensures accountability and helps calculate performance bonuses with zero human bias:

4. Automating GMB Reviews & Annual Maintenance (AMC) Follow-ups

Building a strong brand requires positive customer reviews, yet manually requesting them is often forgotten. Servexa CRM integrates a powerful Follow-up & AMC Reminder engine. When a technician marks a CCTV or networking job as completed, the CRM schedules post-service tasks. For example, it schedules a follow-up 3 days later to request a Google My Business (GMB) review, or 6 months later for a routine maintenance check. Admins can click a direct 'WhatsApp' button next to the reminder, which opens WhatsApp Web pre-populated with a personalized templates, significantly boosting review collection rates and driving local map rankings:


All client details, past service history logs, map links, and review triggers are centralized in a single drawer inside the Client Directory, allowing one-click actions for customer relations:
