PricingCustom quote, implementation costs $10k-$50k+

Editor's takeServiceTitan fits HVAC companies scaling past simple scheduling into serialized inventory and multi-warehouse tracking. The exclusive Lennox integration gives real-time pricing and ordering that few rivals match. The tradeoff is a long, costly rollout better suited to larger teams.

How much does ServiceTitan cost to implement?

Implementation typically runs $10,000 to $50,000 depending on complexity, with monthly costs often cited around $200 to $500 per user.

Does ServiceTitan integrate with Lennox?

Yes. Lennox named ServiceTitan its exclusive Field Service Management partner, giving users real-time product availability and electronic purchase orders.

PricingImplementation from $50,000, mobile licenses from $90/user/mo

Editor's takeFIELDBOSS runs inside Microsoft Dynamics 365 rather than integrating with it, with native touch points into Business Central. The mobile app works fully offline, letting technicians pull equipment history in basements and elevator shafts with no signal. That depth costs real money, since implementation starts at $50,000, with mobile licenses from $90 per user monthly.

How much does FIELDBOSS cost to implement?

Implementation fees start at $50,000. Mobile user licenses start at $90 per user monthly, and back office licenses start at $185 per user monthly.

Does FIELDBOSS work without internet access?

Yes. The mobile app runs fully offline, giving technicians access to service history and checklists. This works in basements or areas with no cell signal.

Editor's takeRO App, formerly RemOnline, publishes exact pricing starting at EUR29 a month, a rarity in field service software where quotes are the norm. It handles multi-warehouse inventory, bin locations, and serialized stock, and messages customers directly through WhatsApp and SMS inside work orders. The base plan covers only 3 employees before per-user fees kick in, and the product leans more toward EMEA markets than the US.

How much does RO App cost?

Pricing is public, starting at EUR29 a month for the Startup plan and reaching EUR99 a month for Enterprise, with a free 7-day trial and no credit card required.

How many users are included in the base plan?

Editor's takeZapium prices by feature tier, not by seat, so growing HVAC teams do not get penalized for adding technicians. Its asset-centric design handles equipment hierarchies and condition-based maintenance triggers that many field service tools treat as an afterthought. The reporting engine is the weak spot, with users asking for more flexibility to customize output.

No. All three pricing tiers, from $299 to $699 per month, come with no user cap at all.

Yes. It supports asset hierarchies, QR code lookup, and condition-based maintenance triggers for detailed equipment tracking.

Editor's takeVAI's S2K Enterprise runs on IBM Power Systems and keeps its mobile field app working even when technicians lose signal in basements or remote sites, syncing once connectivity returns. Serial and lot tracking come built into the base system rather than as paid add-ons, a rarity among HVAC-focused ERPs. The tradeoff is scale: a 20-user minimum near $175 per seat and a $25,000-plus implementation put it out of reach for small contractors.

Does VAI S2K Enterprise work without internet access?

Yes. The mobile field service app operates regardless of internet connection status and syncs data once connectivity returns, according to VAI's own mobile product page.

What is the minimum team size for VAI S2K Enterprise?

20 users. Pricing is estimated at $175 per user per month with a 20-user minimum, plus implementation services that typically start at $25,000, per a third-party ERP pricing breakdown.

PricingOne-time fee from $9,995, plus onboarding

Editor's takeAcctivate turns QuickBooks into something closer to an ERP for HVAC distributors, adding serial and lot tracking, multi-warehouse management, and automated purchasing that QuickBooks alone lacks. Its perpetual license model starts near $9,995 plus onboarding fees, a real capital outlay compared to monthly SaaS tools, but it can lower long-term cost for established shops. Field service reach is limited, since the native mobile app only runs on Android, leaving iOS users on remote desktop workarounds.

How much does Acctivate cost?

It uses a one-time license fee starting around $9,995 for the Starter package, plus mandatory onboarding fees of $2,000 to $4,000 depending on the tier.

Does Acctivate have an iOS app?

No. The native mobile app is designed for Android devices only, so iOS users must connect through a Remote Desktop app instead.

PricingFree plan (100 items), Advanced $29/mo, QuickBooks needs Premium

Editor's takeSortly lets HVAC technicians scan parts with a standard smartphone camera and keeps working offline in basements or on roofs, syncing automatically once back online. Its 'no training or manuals' design and 20,000-plus business user base back a 4.5-star rating across major review sites. The catch is QuickBooks Online sync, which only unlocks on the Premium plan at $299 a month, a steep jump from the $29 Advanced tier most small shops start on.

Does Sortly sync with QuickBooks?

Yes, but only on Premium and Enterprise plans. QuickBooks Online integration is not available on the lower-tier Ultra plan, per Sortly's own help documentation.

Does Sortly need training to use?

No, according to the company and users. Sortly's interface is designed so no training or manuals are required, and G2 reviewers confirm it's easy to train new staff on.

PricingStandard from $229/mo; Inventory management requires Ultimate (quote-based)

Editor's takeWorkiz solves a specific HVAC headache: knowing what's actually in each technician's van. Its 'container' system tracks stock per vehicle, and technicians can assign parts to a job directly from the mobile app, automatically deducting from that van's count. The catch is pricing: full inventory management, the feature this comparison is built around, is exclusive to the custom-quoted Ultimate plan, not the $229-a-month Standard tier. Workiz also carries a lower Trustpilot score than its G2 rating, with documented complaints about billing and difficult cancellations.

Does Workiz's Standard plan include inventory management?

No. Inventory management is exclusive to the Ultimate plan, which requires a custom quote. The Standard plan starts at $229 a month but does not include full inventory tracking.

How does Workiz track van inventory?

It uses a 'container' system where each van functions as its own trackable location. Technicians assign parts to jobs from the mobile app, and the system deducts stock from that specific van automatically.

Editor's takeServiceWorks leans on one specific edge. It is the only platform with direct Marcone inventory integration, letting technicians pull parts automatically into orders. That backend strength does not carry over to the phone in a tech's pocket, though. Reviewers call the mobile app buggy, and one Play Store review says it drains a full battery in 4 to 5 hours.

What makes ServiceWorks different for HVAC companies?

Its Marcone inventory integration is exclusive. The company says ServiceWorks is the only software connected to Marcone inventory, letting technicians automatically pull parts availability and add them to orders.

Is the ServiceWorks mobile app reliable?

Reviews say no. Users report frequent crashes and one Play Store review describes the battery draining from full to zero in 4 to 5 hours. This is the platform's most significant documented weakness.
