Everything Your Generator Business Needs
From the site visit to the startup test to next year's service call—one system for the whole lifecycle.
Standby Install Estimates
Quote the full scope in one document: the Generac or Kohler unit, automatic transfer switch, pad, gas line run, electrical, permits, and startup. Options like load management shown as clear line items.
Deposits Before the Unit Ships
Standby units are real money to have sitting on order. Collect the equipment deposit by card or ACH when the contract is signed, and the balance at startup—with instant payout available.
Vet Customers Before You Order
Check a homeowner against verified contractor reviews and payment history before you order a 26kW unit and book an electrician and gas fitter for the same morning. Know they pay at startup.
Maintenance Agreement Billing
Sell annual service plans at startup and bill them automatically. Scheduled reminders bring you back every year for oil, filters, plugs, and a load test—recurring revenue between installs.
Change Orders & Signatures
Longer gas runs, a meter upgrade, a panel that can't take the transfer switch—when scope changes on site, send a digital change order the customer signs from their phone.
Mobile-First Platform
Quote from the customer's backyard with the pad location in view, photograph the meter and panel for your gas and electrical subs, and collect the startup balance before you leave.

Frequently Asked Questions
Common questions from business owners
Can I collect a deposit before ordering a standby generator?
Yes—and you should. TrustPro lets you collect the equipment deposit by card or ACH the moment the contract is signed, so a Generac or Kohler unit never sits on order against a handshake. Bill the balance at startup, with automated reminders if it slips.
How does customer vetting help a generator installer?
A standby install commits you to an expensive unit, an electrician, a gas fitter, and permit fees before you see the balance. TrustPro lets you check the homeowner against verified reviews and payment history from other contractors first—so the customer who stiffed their HVAC company on a condenser doesn't get to try it on a 22kW install.
Can TrustPro manage annual maintenance agreements?
Yes. Sell the service plan at startup, and TrustPro bills it automatically and reminds you when each unit is due for oil, filters, plugs, battery check, and a load test. Maintenance agreements turn every install into a customer for the life of the unit—and they're the first call when it's time to replace it.
How does TrustPro help during storm-season demand spikes?
When an outage hits the news, the phone doesn't stop. TrustPro keeps every inquiry, site visit, and quote organized in one pipeline so the backlog doesn't swallow deals, and SMS follow-ups keep hot prospects warm while units are on backorder. When stock lands, you know exactly who's signed, who's deposited, and who's next.
Can I coordinate the electrical and gas sides of an install?
Yes. Photograph the service panel, meter, and proposed pad location at the site visit, attach notes on gas line sizing and routing, and everything lives on the job for your electrician and gas fitter. Scope changes—longer runs, meter upgrades—go out as digital change orders the customer signs before work continues.
What does TrustPro cost for a generator business?
Plans start at $29/month with a free 14-day trial—no credit card required. Payment processing is 3.1% standard or 4.1% with instant payouts, and SMS messaging starts at $0.045 per message.
The Complete Business Management Solution
Standby Generator Estimating Software
A standby quote is really four scopes in one: the unit, the electrical, the gas, and the site work. TrustPro lets you present it all as one clean, itemized estimate—the Generac, Kohler, Cummins, or Briggs & Stratton unit, the automatic transfer switch, the concrete or composite pad, the gas line run with sizing, permits, and startup commissioning. Options like load-shedding modules or Wi-Fi monitoring appear as line items the homeowner can accept or decline, and digital signatures lock the scope before you order anything. When the site visit changes the plan, the change order is two minutes on your phone.
Deposits, Startup Balances, and Vetted Customers
Generator installers carry unusual exposure: the unit is ordered weeks out, subs are scheduled, and the balance isn't due until the startup test passes. TrustPro shortens every side of that. Collect the equipment deposit at signing, bill the balance at startup with on-site card or ACH payment, and turn on instant payouts when you want the money the same day. Before any of that, customer vetting lets you check the homeowner against verified reviews and payment history from other contractors—because the person who fought their roofer over a final invoice will happily do it again with a generator already wired to their panel.
Maintenance Agreements: The Other Half of the Business
Installs make the revenue spike; maintenance plans make the business. TrustPro bills annual service agreements automatically and schedules the visits—oil and filter, spark plugs, valve check on air-cooled units, battery test, and a load test to prove the unit will actually start when the grid drops. SMS reminders fill your fall calendar with pre-winter checks, and every serviced unit stays in the system with its model, serial, and service history. When a ten-year-old unit starts throwing codes, you're the company the homeowner already trusts—and the replacement quote is already half-built.
Mobile Software for Generator Crews in the Field
Generator work happens at the meter, the panel, and the pad—not at a desk. TrustPro's mobile app lets you quote from the backyard with the install location in view, photograph the service entrance and gas meter for your subs, and capture the serial and startup readings when the unit commissions. Techs on maintenance routes see each unit's history before they open the enclosure, log what they replaced, and collect payment before the truck leaves. It works in rural driveways with weak signal and syncs when you're back in coverage—your whole generator operation in your pocket.
Grow Your Generator Business
Whether you're an electrician adding standby installs or a dedicated generator dealer with service routes, TrustPro scales with you. Keep storm-season chaos organized, convert every install into a maintenance agreement, and follow up automatically on aging quotes that stalled when the power came back on. The exclusive TrustPro Referral Network accepts one generator company per state, connecting you with homeowners actively shopping for backup power—yours alone, not auctioned to four competitors. Plans start at $29/month, so the software pays for itself the first time a deposit clears before a unit ships.
One Contractor CRM for Every Trade
TrustPro brings estimating, invoicing, scheduling, and payments together for service businesses of every kind.
