Software for the yard running portable generators.

A portable generator is the unit a rental yard sends when a job needs power before the grid gets there — or when the grid drops and the work cannot stop. It runs the tools on a new pad, the lights on a night pour, the pumps that keep a lease producing, and the stage at a weekend event. That flexibility is also what makes generators hard to run as a fleet. They are small enough to vanish on a crowded truck, they live or die on fuel and oil the customer is supposed to watch, and a quiet backup set can foul itself sitting idle while a loaded set burns through a service interval in a week. EquipFlow handles generators the way the yard that built it does — dispatch, billing, maintenance, and return inspection on one record per unit, with the hour meter and the fuel level both captured at return.

Built inside Rental King, right now.

Rental King is a heavy-equipment rental yard in Odessa and Midland, TX. They run portable generators, manlifts, forklifts, light towers, generators, compressors, and water trucks on MSA contracts through the Permian Basin — 24/7, oilfield pace. EquipFlow was designed and first deployed inside that yard. Every feature was tested against their live operation before it shipped. The product runs there today.

Generators are the unit where small leaks add up fast, because the yard runs a lot of them and each one carries fuel, accessories, and the risk of walking off a site. A set that comes back a half-tank short is a refueling cost the yard eats unless the fuel condition was recorded out and in. A set that left without the right cord ends or cam-lock tails is a return trip that kills the margin on a short rental. And a backup unit billed at active rates when it sat untouched, or sitting idle and never billed standby at all, is money read wrong in either direction. When dispatch, billing, maintenance, and inspection all read from one unit record, the dispatcher sends the right accessories, the bookkeeper reconciles fuel and standby without rebuilding the month from memory, and the mechanic services against real run hours rather than a guess. That single-record discipline is what keeps a high-count generator fleet from bleeding quietly.

How EquipFlow handles portable generators on the dispatch board.

A portable generator is small enough to disappear, and that is the first dispatch problem. The unit gets loaded under light towers, pumps, and tooling on the same truck, so the board treats every generator as its own line on the rental record rather than a loose item that rides along uncounted. The second problem is everything that goes with it: a generator without the right cord set, cam-lock tails, or the transfer-switch pigtail the customer expected is a dead delivery and a return trip, so the dispatcher confirms the power-connection accessories on the record before the truck leaves the gate. Fuel matters too — a set dispatched on fumes burns the customer's first hour topping off, so the fuel-out condition is set at dispatch. Because the same wattage class double-books easily across overlapping jobs, the board surfaces the conflict at assignment, not at the gate, on the same responsive screen at any hour.

Billing portable generators — MSA, standby, and site-level tax.

Portable generators rent on day-and-week cycles far more than the hour-meter machines in the yard, so the customer record carries the right cycle and any MSA rate override per equipment class — a jobsite power package and a quiet inverter set bill at their own negotiated rates without the dispatcher holding a sheet in their head. Fuel is the line that gets lost: a generator goes out topped off and should come back topped off, so the rental record tracks the fuel-out condition and the return inspection records fuel-in, turning a short tank into a refueling charge instead of a write-off. When a set sits wired to a panel as backup and never carries load through a shutdown or a rig move, standby is billed at a rate separate from active days. Delivery, pickup, cord and cam-lock add-ons ride the same invoice. Tax follows the delivery-site record, and invoices post to QuickBooks Online on close.

Maintenance on portable generators.

Generator PM is hour-meter driven, and the meter is the only honest record of how hard a set ran, because a unit can idle quietly for a week on a backup job or scream at full load on a fleet of welders for the same calendar span. The hour reading posts when the return inspection records it, and the maintenance module advances the PM clock from that reading so the next service lands on real run time. Oil is the killer on small engines — these sets hold little of it and burn through it under sustained load — so PM leans hard on oil and filter service alongside the air filter, the spark plug or glow plug, and the valve lash check. Stale fuel is the other recurring repair: a carburetor left wet with gummed gasoline becomes a no-start that ties up a bay. Work orders, parts, and meter history live on the unit record, which is also where a damage charge from a return inspection becomes a repair ticket.

Portable Generator return inspections.

Two inspection rhythms apply. The operator-facing check is the customer's responsibility while the set is on rent — oil level, fuel, and a clear exhaust path matter because a generator starved of oil or run in an enclosed space fails fast and dangerously. The yard's own control is the return inspection: before a generator comes off rent, the driver runs a mobile-web checklist on a phone — no app install — records the hour-meter reading and the fuel level, and attaches required photos that cannot be skipped. Generator-specific checks belong here: that the set actually starts and produces power under a brief load, that the breakers and receptacles are intact and not melted, that the cord ends and cam-lock lugs are not burned, and that the engine holds oil without weeping. The inspection ties to the rental record before the truck leaves the customer site, so a dispute over a dead set or a short tank has photos and a timestamp behind it.

What you give up running portable generators in EquipFlow.

EquipFlow is a web app, so the return inspection needs a signal to load. On a remote pad or a back-lot event with no coverage, the driver cannot finish the mobile inspection at the customer site; most yards run it at the yard on return instead, which means the fuel reading, the load check, and the photos land later than ideal. There is no automated fuel metering or telematics today — fuel level and run hours are read by a person at the return inspection, not pulled from the set. And the billing logic is built around the day-week-and-standby model rental yards actually run; a yard with an unusual power-by-the-kilowatt or sub-metered structure should bring it to the demo to be scoped honestly.
