Free Field Service Software Compared (2026)

Search for free field service software and most of what comes back is a free trial: 14 days, then a bill. That's fine if you're ready to pay. It's not much help if you're one person with a van, a phone and a stack of paper invoices, trying to get organized before you can afford another monthly subscription.

A handful of tools do have plans that stay free. Each one has a catch: one user, 30 jobs a month, no invoices, or no schedule. The trick is picking the catch you can live with.

This guide lists seven field service and job management tools with real free plans, what each free plan includes and leaves out, and the popular tools that only offer trials. We make Clevra, so it's listed first. Its free plan has limits too, and we'll spell them out.

Plans and prices were checked on each company's own site on October 28, 2026.

Free field service software in one minute

• Clevra Free: 1 user, unlimited customers, estimates, scheduling, invoices, card payments and a client portal. No time limit.
• ServiceM8 Free: 1 user and 30 jobs a month, with scheduling, estimates, invoicing and the iPhone app.
• Zoho FSM free edition: up to 20 users, but only 30 appointments and 30 invoices a month.
• Connecteam Small Business: up to 10 users with a time clock, schedule and forms, but no estimates or invoices.
• Square Invoices Free: unlimited estimates and invoices, but no job schedule.
• Contractor+ Freedom: an all-in-one contractor app, capped at 5 estimates or invoices a month.
• MaintainX Basic: free work orders for maintenance teams, with no invoicing.

Free plan or free trial?

A free plan stays free until you choose to upgrade. A free trial ends on a date, and then you pay or lose access. Jobber, Housecall Pro, Workiz and Kickserv only offer trials. Joist used to have a free plan and ended it in 2024.

When a free plan is the deal you're after, check three things before you load in your customers: how many users it allows, how many jobs or invoices a month, and what the first paid plan costs when you outgrow it.

Seven free plans, in detail

1. Clevra Free: the whole job, for one person

Clevra is field service software for trade crews of 1 to 15 people, and its Free plan runs the whole job for a solo operator. A homeowner fills in your request form; you send an estimate they approve online; the approved estimate becomes a job on your calendar; and when the furnace is running again, you Generate Invoice and they pay by card from the link.

What's included: one user, unlimited customers, a CRM with notes and multiple properties per client, estimates, scheduling and dispatch, invoices, Stripe card payments with no Clevra platform fee, a client portal, timesheets and a sales pipeline. Email reminders go to clients the day before a visit. There's no time limit and no card needed to sign up.

What's not: Clevra branding appears on your estimates, invoices and portal. Checklists and inspection reports, texts to clients, QuickBooks, automations, advanced reports and AI features start on Pro. The free plan is one user, so the day you hire, you move to Pro at $49 a month ($39 billed yearly) for up to 5 users, or Business at $99 ($79 yearly) for up to 15.

Where Clevra falls short. The Technician app is an iOS beta that can't take photos or payments yet, and there's no Android app. There's no Tap to Pay, ACH, online self-booking or GPS. Card payments are in US dollars only. Every new account can try Pro or Business free for 14 days before settling on a plan (compare plans).

2. ServiceM8 Free

ServiceM8 is a polished, iPhone-first job management app from Australia, available in the US since 2016. Its free plan is for sole operators: 1 user and 30 jobs a month, with scheduling, estimates, invoicing, payments, recurring jobs and the mobile app. Texts cost 10¢ each.

Forms, job costing and asset management need a paid plan. Paid plans have unlimited users and are priced by jobs, from $29 a month for 50 jobs. See our ServiceM8 alternatives guide.

3. Zoho FSM free edition

Zoho's field service app has a free edition that allows up to 20 users, which is unusual. The limit is volume: 30 appointments and 30 invoices a month, and 1 GB of storage. It covers work orders, invoicing, payments and a mobile app for techs.

The calendar view, job costing and offline access are on paid plans, starting with Standard at $30 a month. It's a reasonable pick if you already use other Zoho apps.

4. Connecteam Small Business

Connecteam's Small Business plan is free for up to 10 users, with a GPS time clock, a schedule, unlimited forms and team chat. For a crew that mainly needs to know who's working where, it's hard to beat.

It doesn't send estimates or invoices or take customer payments, so you'd pair it with another app for the money side. Paid hubs start at $29 a month billed yearly. See our Connecteam alternatives guide.

5. Square Invoices Free

Square Invoices sends unlimited invoices, estimates and contracts for free, with deposits, reminders and e-signatures. You pay per transaction: 3.3% + 30¢ for online cards on the free plan.

There's no job schedule or crew calendar, and it isn't built for trades. If you already take payments with Square and keep your schedule elsewhere, it's a simple free option. Plus is $20 a month and lowers the card rate.

6. Contractor+ Freedom

Contractor+ is an all-in-one app for build and service contractors. Its free Freedom plan holds 250 leads and clients and lets you send 5 estimates or invoices a month, which is enough to try it on real jobs.

Scheduling and most other features sit on paid plans, from Pro Team at $58 a month for 2 users. See Clevra vs Contractor+.

7. MaintainX Basic

MaintainX is work order software for maintenance and facilities teams, now part of Autodesk. Basic is free forever with unlimited work orders, though only 2 can have attached procedures, 2 can repeat, and you get 5 photos a month.

It has no estimates, invoices or customer payments, because it's built for an in-house maintenance team, not a business billing customers. For free work orders inside a building you manage, it's a strong choice.

Also free, for one piece of the job

• Busybusy: free GPS time tracking and job costing for unlimited users.
• Wave: free estimates, invoices and bookkeeping, with no scheduling.
• Odoo: one app free with unlimited users; adding a second app, like invoicing, moves you to a paid plan.

Popular tools with no free plan

• Jobber: 14-day trial; Core $49 a month for 1 user billed monthly.
• Housecall Pro: 14-day trial; Basic $59 a month billed yearly, or $79 monthly.
• Workiz: 7-day trial; prices on request.
• Kickserv: 30-day trial; Start $60 a month for up to 5 users.
• Joist: free plan ended in 2024; from $10 a month for 5 documents.

Free software for plumbers, HVAC techs and electricians

There's no separate free "plumbing software" or "HVAC software" worth chasing. The free plans above work for any trade that books visits and bills for them. What changes by trade is the paperwork: a gas safety check, a backflow test, a panel inspection or a drain camera report.

If your trade sends a report after every job, check that the free plan can do it. Most can't: in Clevra and ServiceM8, forms and reports are paid features. See how Clevra is set up for plumbing, HVAC and electrical work.

How to pick

• You work alone and want the whole job, from estimate to payment: Clevra Free or ServiceM8 Free.
• You work from an iPhone and run fewer than 30 jobs a month: ServiceM8 Free.
• You have a small team and low volume: Zoho FSM's free edition.
• You mostly need a time clock and schedule for a crew: Connecteam.
• You only need to send invoices: Square Invoices.
• You run maintenance inside your own buildings: MaintainX.
