Solar Software Stack
Most of the software spend happens before anyone climbs a roof
125+ tools, walked through in the order the decision actually happens — the platform that runs the shop first, then the tools built for the trade, then what it all costs at your size.
Solar inverts the usual trade economics. The install is a day or two of labor; the sale is a weeks-long consultative process involving a shade study, a production estimate, a utility bill analysis, and a financing decision the homeowner has to be walked through. Add the paperwork that follows — incentive and rebate filings, interconnection application, AHJ permitting, inspection, then permission to operate before the system can legally produce a kilowatt — and the administrative tail dwarfs the field work. Software that only manages crews solves the smaller half of the problem.
That makes design and proposal tooling load-bearing in a way it isn't for a service trade, because the proposal is a financial projection the customer is being asked to believe. It also means the real operational risk is a permit or interconnection application sitting in a queue while a financed customer waits, which is why pipeline visibility across permitting agencies and utilities matters more than dispatch efficiency. After PTO the relationship shifts again, to monitoring and production guarantees — a long-tail obligation that residential service trades simply don't carry.
What runs the shop
This is the one decision that constrains every other tool you buy — and it isn't a question of which platform is best. It's which kind of work you sell.
Pick the lane that matches how the money actually comes in, then judge platforms only against others in that lane. Comparing a residential dispatch tool to a project-costing platform tells you nothing except which one has more features.
Built around the contract rather than the call: asset histories per site, planned maintenance visits, and invoicing that survives a customer's AP department. Heavier to set up than a residential tool, and overkill if most of your revenue still walks in from homeowners.
simPRO is a cloud-based field service management and job management platform purpose-built for trade contractors. Founded in 2002 in Brisbane, Australia by an electrical contractor and a software engineering student, it covers the full job lifecycle from quoting and estimating through scheduling, dispatch, inventory, invoicing, and reporting. It is widely used by HVAC, plumbing, electrical, fire protection, and general-contracting businesses across Australia, New Zealand, the UK, and the US. The platform scales from single-trade service companies to multi-division commercial contractors with project management complexity.
Job costing against a bid is the whole product here — change orders, RFI and submittal tracking, progress billing. Necessary the moment a missed change order costs more than a week of idle trucks, and heavy overhead if you're still running a service board.
Autodesk Build is a cloud-based construction project management platform that evolved from PlanGrid and BIM 360, now part of the Autodesk Construction Cloud (Forma Build) suite. It centralizes document management, RFIs, submittals, cost management, scheduling, field operations, quality, and safety workflows across the full construction project lifecycle. Trusted on 2M+ projects globally, it is used by general contractors, specialty subcontractors, and owners on commercial, industrial, and institutional projects.
Built for solar
Most software a solar contractor runs was written for contractors in general. These were written for this trade — which usually shows up as takeoff, estimating, or compliance workflows that a general-purpose tool makes you rebuild by hand.
Solar design and sales platform — remote 3D roof modeling with LIDAR shade analysis, NEC-validated layouts, permit-ready plan sets and customer proposals, all without a site visit.
Solar design, proposal and permitting platform from Enphase — LIDAR 3D modeling, NREL/NYSERDA/CEC-verified shade analysis, and automated permit packages.
A short list on purpose — software written for solar specifically is rare, and we would rather show two real ones than pad this with general-purpose tools.
The rest of the stack, by role
Everything below fills a specific job. Tools are only compared against others doing the same job, because "is Gusto better than Procore" is not a real question — the useful question is always which payroll tool, or which documentation tool.
The books
Job costing, invoicing, and a P&L your accountant will accept without re-keying it. This is the tool you're most likely to still be running in ten years, so the switching cost is real — weight it accordingly.
Cloud ERP platform for construction and field service companies with financial management and project tracking.
ALASCO provides comprehensive ERP software specifically designed for the construction industry. It helps contractors manage their financials, projects, and operations with integrated modules.
Anterra provides financial reporting and business intelligence software specifically designed for the construction industry. It helps general contractors and specialty trades gain deeper insights into project profitability and overall business performance.
BlueTape provides flexible payment solutions and trade credit specifically designed for contractors to purchase materials and manage cash flow. It helps construction businesses extend payment terms with suppliers and streamline B2B transactions.
Payroll & crew
Timesheets, onboarding, and — on prevailing-wage work — certified payroll. The compliance paperwork here scales faster than headcount does, which is why owners usually buy this a year later than they should have.
Time tracking and scheduling software built for field service and construction companies.
Time and attendance tracking software for construction companies with GPS verification and payroll integration.
BuildForce provides a workforce management platform designed to help skilled trades contractors find, hire, and manage their labor force. It connects contractors with qualified craft professionals and offers tools for scheduling, time tracking, and compliance.
BuildStream is a workforce management platform designed for the construction industry. It helps contractors, subcontractors, and project owners manage their workforce, ensure compliance, and streamline project staffing.
Job documentation
Photos, notes, and sign-offs attached to the job rather than to somebody's phone. This is the record that settles a dispute a year after the crew left.
DocuSign is the market-leading electronic signature and intelligent agreement management platform, used by 1.7 million customers including 95% of Fortune 500 companies. Widely adopted by contractors across all trades for proposals, contracts, change orders, lien waivers, and service agreements.

Listed on NASDAQ as DOCU.
CompanyCam is a photo documentation and field communication platform purpose-built for contractors. Founded in 2015 by Luke Hansen out of his family's roofing business in Lincoln, Nebraska, the platform lets field teams capture timestamped, GPS-tagged photos and videos, annotate images, manage project timelines, run AI-powered checklists and reports, collect in-app payments, and collaborate with customers and subcontractors — all organized by job. Serving 140,000+ contractors and pros across 50+ trades, CompanyCam is a documentation-first layer that integrates with field service management, estimating, and CRM tools rather than replacing them.
PandaDoc is a cloud-based document automation and e-signature platform that helps contractors and sales teams create proposals, contracts, and quotes faster.

Getting the phone to ring
Paid lead channels and marketplaces. Genuinely useful before you have referral flow, and expensive to stay dependent on — judge these on cost per booked job, never cost per lead.
Angi (formerly Angie's List / ANGI Homeservices) is the leading US home services marketplace connecting homeowners with local service professionals across 500+ categories. Formed by the 2017 merger of Angie's List (founded 1995) and HomeAdvisor (founded 1998 as ServiceMagic), and rebranded to Angi in March 2021. The platform operates a pay-per-lead model (Angi Leads), display advertising (Angi Ads), and a fixed-price instant-booking service powered by the 2018 Handy acquisition. Angi completed its spin-off from IAC on April 1, 2025, becoming an independent public company (NASDAQ: ANGI). Revenue in 2025 was approximately $1.05B (declining YoY as platform shifted to homeowner-choice lead model). As of 2025 the platform counts roughly 200,000 active service professionals across all trades.
Thumbtack is a nationwide online marketplace connecting homeowners with local service professionals across 500+ project categories. Founded in 2008 and headquartered in San Francisco, CA, Thumbtack operates a pay-per-lead model where contractors pay only for qualified leads — never a commission on completed jobs.

Thumbtack offers AI-powered matching, professional profile pages with reviews and portfolio photos, background check and license verification badges, and integrations with ServiceTitan, Jobber, Workiz, and Google Calendar. It is strictly a lead generation and customer acquisition platform — job management, scheduling, dispatch, invoicing, and CRM must be handled in a separate FSM tool.
Largest privately-owned home improvement lead generation platform specializing in solar, roofing, HVAC, and windows, connecting contractors with pre-screened homeowner leads.
Trucks & equipment
GPS, maintenance intervals, and being able to answer "where's the van?" while the customer is still on the phone. Worth buying at roughly the third truck.

It is widely used by HVAC, plumbing, electrical, fire protection, and general-contracting businesses across Australia, New Zealand, the UK, and the US. The platform scales from single-trade service companies to multi-division commercial contractors with project management complexity.
What it costs, by size
A solo operator and a 40-truck company buying the same platform pay differently and use it differently. Pick your company type to see it highlighted first — each stack also lists the signals that you've outgrown it.
Solo / 2-Truck Owner-Operator
residential1–3 employees · $100K–$500K
The self-employed tradesperson or micro-crew running on personal hustle and minimal tooling. Jobs are dispatched from a phone, invoices are often paper or a basic app, and new work arrives through word-of-mouth and marketplace listings. Technology decisions are driven by cost sensitivity and simplicity, not capability gaps. The single most common gap at this stage: no formal scheduling or dispatch tool — appointments tracked in a personal calendar or text messages.

Picks are this archetype's typical stack where this trade has those tools, topped up with the strongest tools the trade actually has in each category.
Approximate — assumes a ~2-person company (this archetype's typical size) and one tool per category. Priced lines use each vendor's published entry price, so per-seat tools are a starting point rather than what 2 people cost. Your actual stack and headcount will change this.
You've outgrown this stack when
- →Revenue crossing $250K with repeat customer base growing, making lead-gen marketplace fees increasingly costly relative to owned relationships
- →Hiring a first technician or helper, triggering a need for payroll, scheduling visibility, and job assignment beyond the owner

Residential Remodeler / Specialty Contractor
residential5–50 employees · $1M–$15M
A project-based residential contractor — kitchen and bath, additions, roofing, windows, or specialty trade — where each job is a discrete project with an estimate, proposal, signed contract, draw schedule, and final invoice. The business runs on proposal conversion and job gross margin, not service-call volume. CompanyCam is nearly universal for documentation. The gap is almost always CRM and change-order discipline. The single most common gap at this stage: no systematic crm — leads and follow-ups are tracked in spreadsheets or the estimating tool's weak pipeline view, causing lost bids.

Commercial Service Contractor
commercial25–250 employees · $5M–$50M
A commercial-focused HVAC, plumbing, electrical, or facilities service company operating under multi-year maintenance contracts with building owners, property managers, and facility directors. Revenue is recurring and agreement-based, technicians are skilled and often certified, and regulatory compliance (OSHA, EPA refrigerant, NFPA) is a real operational burden. The FSM platform is the operational core, but fleet management, safety compliance, and customer-facing portals are persistent gaps at this tier. The single most common gap at this stage: safety compliance documentation is handled manually or in disconnected tools, creating audit risk and inconsistent incident reporting across job sites.

Frequently asked questions
How were these tools chosen?▾
Tools are only ever compared against others doing the same job — accounting against accounting, dispatch against dispatch. Within a job, we order by how often a tool shows up in real contractor stacks, then vendor tier, review rating, and pricing transparency. Never by who pays us. See /how-we-vet.
Are these prices accurate?▾
Where a vendor publishes pricing, we show it exactly. Where they don't, we show a sourced, dated estimate range instead of guessing — and label it as an estimate. Tools with neither are marked quote-only and excluded from the cost totals.
Why does my stack cost differ from the totals here?▾
The per-archetype totals assume one tool per category and a company sized to that archetype's typical range — your actual headcount, trucks, and tool choices will move the number.
Why isn't there one "best" tool at the top?▾
Because a single ranked list would be comparing your accounting software to your dispatch software, which tells you nothing. The decision is really a sequence: pick the platform that matches how you sell work, then fill in the roles around it.
