Accounting and Field Software for Service Contractors: HVAC, Plumbing, and Electrical

If you run an HVAC, plumbing, or electrical service business, your software question is really two questions stacked on top of each other. There’s the field-service platform that runs your dispatching, scheduling, pricebook, and invoicing, and there’s the accounting system underneath that owns your books. Picking the right combination, and understanding which layer does what, is what keeps your financials clean as you grow. This guide breaks down both layers and which tools fit which size of shop.

A quick note on scope: service contractors (recurring service calls, replacements, maintenance agreements) have genuinely different software needs than project-based contractors (general contractors, remodelers). This article is about the service side. If you do longer project work, the priorities shift, and that’s a separate conversation.

The two layers of your stack

The field-service platform is the system your techs and dispatchers live in. It handles scheduling and dispatch, the pricebook, estimates and good-better-best proposals, work orders, mobile invoicing, and payment collection. This is the operational heart of a service business.

The accounting layer sits underneath and owns the books: the general ledger, financial statements, tax-ready records, and the job or class tracking that tells you which work is actually profitable. For the overwhelming majority of service contractors, this layer is QuickBooks Online.

Most field-service platforms are built to integrate with QuickBooks rather than replace it, which is why understanding both layers matters. You’re not choosing one tool, you’re choosing a combination that talks to itself cleanly.

The accounting layer: why QuickBooks Online is the default

QuickBooks Online is the de facto standard for service-contractor accounting, and the reasons go beyond habit. Nearly every field-service platform you’d consider (ServiceTitan, Housecall Pro, FieldEdge, Jobber) integrates directly with QuickBooks. Your accountant almost certainly works in it. And the support ecosystem dwarfs any alternative.

For job costing, QuickBooks Online handles service work well enough through its Projects and class-tracking features. It won’t satisfy a general contractor running a multimillion-dollar project with AIA billing, but for an HVAC company, electrician, or plumber tracking revenue and costs by job, it does the work. The plan that matters is Plus (around $115 per month as of 2026), because that’s the tier that includes project tracking. The Advanced tier (around $200 per month) adds users and reporting if you scale into it.

Xero is a capable alternative, particularly if you want unlimited users without per-seat fees, but the contractor ecosystem in the US runs on QuickBooks, and most US CPAs default to it. For most service contractors, QuickBooks Online is the path of least resistance and the broadest compatibility.

The field-service platform layer, by size of shop

This is where the choice really varies, and it varies mostly by how many techs you run and how complex your operation is.

ServiceTitan sits at the top end. It’s a comprehensive, end-to-end platform built for larger trade businesses, and it integrates with both QuickBooks Online and Sage Intacct. Pricing runs roughly $250 to $400 per technician per month, plus implementation. It’s powerful, with deep reporting and the ability to handle both service and project work, but it’s genuinely built for shops above about $2M in revenue with eight or more techs. Below that, most companies find it more than they need.

Housecall Pro targets the smaller end, roughly one to seven techs, at around $49 to $189 per month plus per-user fees. It’s clean, fast to set up, strong on customer communication and online booking, and it syncs with QuickBooks Online. The tradeoff is reporting depth: if you eventually need granular per-tech profit and loss, you can outgrow it.

FieldEdge is a strong mid-market option for HVAC, plumbing, and electrical, and is often cited for having one of the cleanest QuickBooks integrations in the market. It’s a good fit for established mid-market contractors who live in QuickBooks and want tight, real-time sync between the field and the books.

Jobber fits small to mid-sized contractors who want solid scheduling, quoting, invoicing, and payments without enterprise complexity. It’s a common step up from spreadsheets or the most basic tools.

There are others (Workiz, Service Fusion, ServiceTrade for commercial mechanical, and more), but these four cover most of the decision space for residential and light-commercial service trades.

All-in-one vs. building a stack

There are really two philosophies here, and it’s worth knowing which one you’re choosing.

One philosophy is the all-in-one platform: ServiceTitan, Housecall Pro, and FieldEdge each try to handle dispatch, CRM, invoicing, and reporting under one login, syncing to QuickBooks for the books. The advantage is one vendor, one training curve, one data source, and usually a lower total cost of ownership for a company under fifteen trucks. The tradeoff is that you inherit the platform’s opinions on every workflow, and swapping out one weak module is rarely possible.

The other philosophy is building your own stack: pick the strongest tool in each category and integrate them. This gives you best-of-breed in each spot, but you take on the integration work and the risk of gaps between systems where data gets miscoded or lost. For most service contractors, the all-in-one path is simpler and cleaner, especially early on.

How to actually choose

The honest decision framework comes down to a few questions. How many techs do you run, and what’s your revenue? That mostly sorts you between the entry tier (Housecall Pro, Jobber), the mid-market (FieldEdge), and the enterprise tier (ServiceTitan). Do you need deep per-tech and per-job profitability reporting, or just clean scheduling, invoicing, and payment? And critically, does your chosen platform integrate cleanly with the accounting layer underneath, because a field platform that syncs poorly to QuickBooks creates more bookkeeping work, not less.

That last point is where a lot of contractors get burned. The flashiest field platform is worth nothing if its accounting sync is clumsy, because you’ll pay for it every month in reconciliation headaches. The integration quality matters as much as the features.

The bottom line

For most service contractors, the answer is QuickBooks Online Plus as the accounting foundation, paired with a field-service platform sized to your shop: Housecall Pro or Jobber for smaller operations, FieldEdge for mid-market QuickBooks-centric shops, and ServiceTitan once you’re large enough to justify it. The right choice depends on your size, your reporting needs, and how cleanly the pieces talk to each other.

Software is only half the battle, though. Even the best stack produces unreliable numbers if the accounting underneath isn’t set up for how service work actually flows.
