FieldOps | Multi-Vendor Service Management Platform With Flutter Mobile App

FieldOps is a field service management platform for AC, appliance, cleaning, pest control, repair and similar service companies. It runs your own service company and, if you switch it on, a multi-vendor marketplace of other service companies: a platform admin console, a company workspace for work orders, dispatch, customers, assets, contracts, quotations, invoices, inventory and teams, a customer portal, a public website with online booking and live job tracking, and a native Flutter app for technicians, managers and customers (Android and iOS). One item, two deliverables: the Laravel 13 web platform (1,121 routes, including 170 REST API v1 routes) and the Flutter app that uses that API.

Technicians accept jobs, navigate, check in, fill checklists, take before/after photos, use parts from their van stock, collect the customer’s signature and payment, and keep working offline. Customers book online, follow the technician on a map, approve quotations and pay invoices. English, Bangla, Arabic (right-to-left) and French are included on the web and in the app.

AI Disclosure

Optional AI features use YOUR own Anthropic (Claude) account. Job summaries and service reports, customer reply drafts, request classification, checklist generation and knowledge-base answers send the job notes, messages and uploaded documents involved to Anthropic’s Claude API with the API key you configure (a platform key, or each company’s own key). No key is included; without one the AI buttons stay off and the rest of the platform works normally. Usage is billed to you by Anthropic and is not included in the item price. A monthly token cap, a rate limit and a usage log are built in. AI tools were used to create this item. AI tools assisted in creating parts of the source code (Laravel and Flutter), the documentation, the README files and the listing graphics. The listing graphics are built from real screenshots of the running application; no AI-generated images are shown as product screens. All code and content were reviewed and tested by the author, and the item ships with its automated test suites.

Third-Party Accounts and Costs

You need your own accounts with these services and pay their fees directly. None of them is included in the item price. Payment gateways: SSLCommerz, Stripe, bKash, PayPal, Razorpay, Paystack, Flutterwave (per-transaction fees; manual / offline and bank transfer work without any gateway) SMS through any HTTP SMS provider, and WhatsApp Cloud API (Meta) for customer messages Firebase (Google) for push notifications in the app, under Google’s terms Anthropic API key for the optional AI features E-mail delivery: SMTP, Amazon SES, Postmark or Mailgun Google reCAPTCHA keys (optional) and your own OSRM routing server for route optimisation in production Hosting, domain and SSL; Apple Developer and Google Play Console accounts to publish the app All of these integrations were tested with simulated responses in the automated tests; test each one with your own sandbox credentials before going live.

The demo logins are also offered on the demo login page. On the demo, password changes, payment and messaging credentials, system update, backup download and deleting companies, accounts or users are blocked, and the demo data is restored every 6 hours, so please do not change the demo passwords. A fresh installation creates only the company and admin account you enter in the installer.

The screenshots of this item show the web platform (admin console, company workspace, customer portal, website) and the Flutter app, captured from a seeded installation.

Important Notes About Third-Party Services

Your own accounts and keys: payment gateways (SSLCommerz, Stripe, bKash, PayPal, Razorpay, Paystack, Flutterwave), your SMS provider, WhatsApp Cloud API, e-mail delivery, Firebase Cloud Messaging, Anthropic (AI), Google reCAPTCHA and an OSRM routing server are external services. You create your own accounts and supply your own API keys. These providers charge their own fees, which are not included in the item price. Hosting, domains and Apple/Google developer accounts are not included either.

How integrations were tested: payment gateways, SMS, WhatsApp, push, AI, OSRM, reCAPTCHA and the purchase code check were verified during development with simulated (faked) HTTP responses in the automated test suite. Test each integration with your own sandbox credentials before going live.

Honest notes: message drivers default to a log file until you configure them. Route optimisation uses a public OSRM demo server by default; use your own server in production. Map tiles come from OpenStreetMap under its usage policy. Accounting is a CSV export for QuickBooks or Xero, not a live sync. The app’s job chat has no realtime push. Build, sign and test the app on your own Android and iOS devices before publishing. Composer, npm and Flutter packages remain under their own licences (see the documentation for credits).
