Why I Built Right Hand

Right Hand started with a phone call to my brother.

He's a master plumber in Northern Colorado. Three kids. Contractors up there are hurting for work right now. Not him. He's got more than he can handle, because he's the guy you call when the first guy screws it up.

On that call I asked him about his last five jobs. What he did, what he charged, what the materials cost.

His answer:

“I haven't billed in the last two weeks.”

Two weeks of completed work. Customers happy, money earned, and not one invoice sent. He also couldn't tell me what any individual job had actually made him, because he'd never had the time to break one down. This from a tradesman at the top of his market, running on a few hours of sleep, doing fourteen-hour days.

That conversation reframed the problem for me. My brother doesn't have a work problem — he has an office problem. He is simultaneously the plumber, the receptionist, the scheduler, the estimator, and the bookkeeper. The first job happens in crawlspaces all day; the other four are supposed to happen at the kitchen table at night, competing with dinner and bedtime. Predictably, they lose. Calls go unanswered, quotes go out late, and finished work sits unbilled — not from carelessness, but from arithmetic. There are only so many hours.

This pattern isn't unique to him. Most of the several million home-service businesses in the US are one-person operations, and the industry data tells the same story everywhere: roughly a quarter of calls to home-service businesses go unanswered, fewer than 3% of callers leave a voicemail, and most simply call the next contractor on the list. The solo operator's biggest competitor isn't another tradesman — it's his own missed calls and unsent invoices.

The existing solutions didn't fit him. Field-service platforms are built on the assumption that a business will grow into an office: learn a dashboard, live in an app, pay per seat, eventually hire someone to manage the software. That's a reasonable model for a five-truck shop. It's a poor one for a tradesman who is deliberately staying solo and needs the administrative work to disappear, not relocate into another system he has to operate.

Some background on me: I'm not a software company, and I didn't come to this from the tech side. I spent the past few years working in the remodeling world, and I'm pursuing a PhD in industrial-organizational psychology — the study of how work affects people and how to design it better. What I saw in my brother's situation was a textbook case of role overload: one person doing five jobs, with the invisible four quietly taxing the visible one. I couldn't answer his phone for him. But this was a solvable design problem.

So I built Right Hand around three principles.

It works where the contractor already works: the text thread. No app to download, no dashboard to learn. When a customer calls and he's under a sink, Right Hand answers, asks the right questions, checks his real schedule and drive time, and books the job. When a job is done, he texts “Smith done, invoice $1,850” — the invoice goes out, payment comes back, and QuickBooks stays current. The two-weeks-unbilled problem disappears, because billing now takes less effort than not billing.

It knows its limits. Right Hand never quotes a price and never negotiates. Anything involving pricing, scope changes, or technical judgment gets escalated to the contractor. If a message looks like an emergency, it flags him immediately and holds the response for his approval. The business's name is on the truck; the judgment calls stay with its owner.

It's priced for a business of one. Free to start, no per-seat pricing, no contract. It earns a small percentage when the contractor actually gets paid — which means the incentives point in one direction: helping him collect.

The measurable result I care about is simple: work billed the week it's finished, calls answered while he's on the job, and evenings that belong to his family instead of the backlog. The industry has spent a decade building software for contractors who want to become managers. Right Hand is for the ones who just want to do the work — and have the office run itself.

If you run a one-person shop and any of this sounds familiar — especially the unbilled work — it's free to try, with no credit card and nothing to install. It works in the text thread you already use.
