Radon Mitigation Business Invoicing App (2026)
Radon mitigation is a flat-priced system install with variables — sump versus slab, fan size, exterior routing — usually on a real estate closing deadline. ShowTheReceipts ($15/mo) saves the system tiers and add-on lines, takes a deposit when the date is booked, and sends a same-day invoice with the post-mitigation test result attached, which is what the closing file actually needs.
How we picked
Entry-plan prices as published in 2026, taken from each vendor's own pricing page or a recent third-party summary. Judged on the solo mitigator's real workflow — flat system pricing with configuration variables, deadline-driven scheduling, post-test documentation, and fast invoicing to buyers, sellers, or agents — not on continuous radon monitor fleets, lab result portals, or state reporting systems.

Someone else’s deadline runs your calendar
Radon work is nearly always attached to a real estate transaction. The closing date is fixed, the inspection period is short, and everyone involved is anxious — which makes scheduling and documentation the whole product, alongside the pipe.

The lines a mitigation quote needs
- System type — sump tie-in, sub-slab suction, crawlspace membrane
- Additional suction points — per point
- Fan — by model and static pressure
- Routing — interior versus exterior, with finish considerations
- Electrical — dedicated circuit if required
- Sealing — cracks, sump lid, membrane edges
- Post-mitigation test — its own line
The paperwork is what the closing needs
An installed system with no test result is, to a closing agent, an unfinished job. Send the invoice and the post-test together — it closes the file, satisfies the buyer, and gets you paid inside the transaction rather than after it.
Confirm the payer in writing
Buyer, seller, agent, or split — decide it before the truck moves. Once the house closes, everyone’s incentive to sort out your invoice evaporates simultaneously.
Frequently asked questions
How should a radon system be priced?
As flat tiers by configuration — sump-pit tie-in, sub-slab suction with one or two suction points, crawlspace membrane — with fan size, exterior routing, and electrical as add-on lines. Hourly pricing makes no sense to a buyer working against a closing date and no sense to you once you've installed fifty.
Who do I invoice on a real estate transaction?
Whoever agreed to pay, confirmed in writing before you install — buyer, seller, or occasionally split at closing. 'The other side is paying' is how more mitigators than you'd think end up chasing a completed job weeks after the house changed hands.
Should the post-mitigation test be a separate line?
Yes. It's a distinct service performed 24-48 hours after the system runs, it's what the closing file needs, and printing it separately shows the buyer they're getting verification rather than a promise.
Do I need a deposit?
On closing-deadline work, a deposit at booking holds the slot on a calendar everyone wants. Fan, pipe, and a full day are committed the moment you schedule — a deposit is what makes a cancelled contract someone else's problem, not yours.
