OpenFieldPro

OpenFieldPro is an open-source field-service management system that connects customer records, scheduling, jobs and payment in a self-hosted package. It is most suitable for service businesses with technical capacity to run their own infrastructure and tailor integrations. The unlimited, no-cost core is attractive, while its release-candidate hardening makes production risk a central buying consideration.

Overview

The system follows a lead-to-payment workflow: CRM records and property details feed scheduling and dispatch, then work orders, estimates, invoices and payments. Equipment history, service plans, documents, reviews and reporting extend it beyond basic job tracking. That breadth can consolidate office operations, but teams wanting a turnkey vendor-operated service will find self-hosting responsibilities and the stated release status significant drawbacks.

OpenFieldPro is licensed under GNU Affero General Public License version 3. Its repository includes helpers for installation, updates, backups and restores, which reduces the routine work of operating a private deployment without removing the need for someone to own that work.

Key features

CRM, customer and property records, equipment history, scheduling, dispatch, work orders, estimates, invoicing, documents, service plans, reviews and reporting cover the main administrative cycle. A dispatch board, online booking, estimate builder and invoice payments are explicitly included, making the core relevant to plumbers and other appointment-based contractors.

Technician mobile workflows have offline foundations, useful when crews work beyond reliable connectivity. Estimates handle line items, and payment workflows include offline payments, optional Stripe checkout and Stripe webhook processing. These options cover common quote-to-cash paths, though the product does not promise every payment provider or method.

A plugin registry, scoped API tokens and outbound events provide an integration surface for teams that need to connect other systems. The listed architecture—Next.js web frontend, Fastify API, React Native Expo mobile app and PostgreSQL—will be most approachable to organizations comfortable maintaining a modern JavaScript and database stack.

Security safeguards include rejecting default or short JWT secrets and wildcard or missing production CORS settings at startup. Bounded route-level rate limits apply to authentication, public booking, uploads and checkout. The project describes no telemetry or phone-home licensing, with optional entitlements verified locally, a meaningful advantage for privacy-conscious operators.

Pricing

The free plan is genuinely unrestricted on the listed operational records, so it fits growing teams that can supply hosting and administration. There is no paid tier described to provide managed hosting or vendor support. Support is handled through GitHub Issues for bugs and feature requests and GitHub Discussions for questions and ideas, which suits community-oriented teams more than organizations requiring a formal service desk.

Platforms

OpenFieldPro provides web, API, Android and iOS access, alongside self-hosted deployment. The combination supports office staff, integrations and technicians without requiring a single device ecosystem.

Who it's for

Choose it for a field-service company that wants ownership of data and deployment, unlimited core usage and the ability to integrate or modify an open-source system. It is a weaker fit for teams without server administration skills, businesses that need a mature production release immediately, or buyers seeking contractual vendor support.

Pros and cons

Pros

• Unlimited users, technicians and core records at no cost, removing growth-based seat and job charges.
• One workflow spans CRM, dispatch, work orders, estimates, invoicing and payments.
• Offline-oriented mobile foundations help technicians working with intermittent connectivity.
• Self-hosting tools, local entitlement checks and no telemetry support deployment and privacy control.
• Scoped tokens, plugins and outbound events offer practical integration points.

Cons

• Release-candidate hardening is still in progress, so production adoption carries software-maturity risk.
• Self-hosting, backups, updates and security configuration remain the customer's responsibility.
• Support is routed through public GitHub Issues and Discussions rather than a stated paid support channel.
• Payment coverage centers on offline payments and Stripe options; broader provider coverage is not established.

Alternatives

Plumbing Software is a useful category starting point when you want to compare plumbing-focused tools.

Pick Opsler instead if a hosted freemium product with Android, iOS, macOS, web and Windows apps suits a small operation; its free Budding plan is limited to two seats and 50 jobs per month.

FieldBench is preferable when you want a conventional freemium service with a one-user, 20-jobs-per-month free tier and a paid Starter option.

Choose ServiceM8 for a freemium mobile-first option whose free plan covers one user and 30 jobs per month, with SMS and AI-use charges.

Contractor+ fits buyers seeking a free-forever plan with basic CRM, up to 250 leads and clients, and five estimates or invoices monthly.

Consider BigChange when you want paid plans with support, live tracking, scheduling, mobile tools, quotes, invoices and business intelligence priced by request.

ServiceWorks is a paid alternative with a Bronze plan at $150 a month and an included API-credit allowance.

Commusoft offers paid, modular plans covering job tracking, forms, contracts, scheduling and online booking, with custom pricing.

Fieldpoint is another paid, self-hostable option with pricing supplied by request.

Verdict

OpenFieldPro is the right choice for technically capable service businesses that want an open-source, self-hosted lead-to-payment platform with unlimited core usage and strong deployment control. Look elsewhere if production maturity, managed hosting or formal support matters more than ownership and zero license cost.
