Every growing trades business eventually faces the same hiring decision and almost everyone gets the order wrong. The instinct is to hire another technician, another set of hands generating revenue. The actual highest-leverage hire, almost every time, is the first office person. The one who answers the phone, runs the schedule, takes payment, and gets you out of the truck. They don't generate revenue directly; they let you generate two to three times more of it.
This is also the hire most owners delay too long. The reasons are predictable: I can do it myself, the office work isn't that much, I can't afford it yet, I don't know exactly what they'd do. All of these are usually wrong by the time you're asking them. The signals below tell you you're past the point where the answer is "yes, hire now."
The signals you're ready.
You don't need all of these to be true, but if three or more are showing up regularly, the decision is made.
Quotes after dinner. Invoicing on Sundays. Payroll at 11pm. If the only time you can get to the administrative work is after the work day ends, you've quietly added a second job. Hiring an office person ends that second job.
Calls go to voicemail because you're under a sink. Quotes that should go out same-day take three days. Customers who would have booked don't, because the next plumber called back faster. Every lost call has a revenue number attached. Most shops underestimate it by half.
Once there are two or three techs in the field, the dispatch and coordination job is real. Scheduling the next day's work, making sure parts arrive at the right job, handling the mid-day call about a problem. This is a job, and it stops fitting between your own appointments.
The shop has been at the same revenue for two or three quarters. Not because demand is missing, but because there's no capacity to schedule it, quote it, and bill for it. You're the bottleneck and the team is waiting on you. This is the most expensive signal. You can usually calculate exactly what the missing revenue is.
What the role actually does.
The mistake is hiring "an office person" without defining what they own. Without a clear scope, they show up Monday, you give them three things to do, and then you keep doing everything else because you don't quite trust they can handle it. Six months in, they've done three things really well and nothing else changed.
The right scope for the first office hire is broad but defined. They own:
- The phone. Every inbound call during business hours goes to them. They book, they qualify, they escalate when needed.
- The schedule. They own the daily and weekly job board. You provide priorities; they sequence the work.
- Quoting follow-up. Quotes go out, they track them, they follow up on the ones that haven't decided in three days.
- Invoicing and payment. Once a job is done, they invoice. They follow up on overdue accounts.
- Basic customer service. Routine questions, scheduling changes, post-job satisfaction calls.
That's not five jobs; it's one job, and any competent organized person who likes structure can do it. The hiring difficulty is not finding the skills. It's finding the right temperament. Calm under pressure. Comfortable on the phone. Detail-oriented. Doesn't need constant direction. The skills can be taught; that personality can't.
The hiring criteria that matter.
Three criteria. Everything else is noise:
Phone presence. You will hear it on the first call. Are they warm? Clear? Do they put customers at ease? An office person who sounds anxious on the phone will lose you bookings; one who sounds confident will close them.
Organizational instinct. Ask in the interview: "How do you keep track of your own commitments? Walk me through it." If the answer involves a system (a calendar, a to-do app, a notebook with a routine), they have the instinct. If the answer is "I just remember" or vague, they don't.
Cultural fit with the customer base. Trades customers are mostly homeowners with practical problems. Your office person has to make them feel like they're being taken seriously by someone competent. The wrong cultural register (too corporate, too casual, too anxious) costs you on every call.
Skills you can teach in two weeks: the software, the scripts, the pricing, the standard responses. Personality you can't teach. Hire for personality. Train for skills.
The first 90 days.
The most common failure of the first office hire is not the hire. It's the onboarding. You're busy, they're new, you give them the password and assume they'll figure it out. They figure out maybe 60 percent of it; the rest stays as questions they keep bringing to you, and within three months you're frustrated they're "not picking it up" while they're frustrated nothing was actually documented.
The fix is a structured first 90 days. Doesn't have to be complex:
- Days 1 to 14: shadow you. Sit in on calls, watch the scheduling, see how quotes are built. Take notes.
- Days 15 to 30: they handle the easy stuff with you as backup. Inbound calls for routine bookings, basic scheduling, invoice generation.
- Days 31 to 60: they own the day-to-day. You check in once daily, in writing, on what's outstanding.
- Days 61 to 90: they own everything in scope. You meet weekly to discuss patterns, not transactions.
By day 90 you should be spending one to two hours per week on operations they manage, down from twenty or thirty. That's the math of the hire. If it isn't tracking there by month three, either the role isn't scoped right or the person isn't the right fit. Both are fixable.
The order of delegation.
Don't try to hand everything over at once. The order that works:
- Inbound phone calls and routine scheduling (week 3). Immediate relief.
- Invoicing and payment processing (week 4-5). Cash flow accelerates because invoices go out faster.
- Quote follow-up (week 6-7). Win rate improves because nobody falls through the cracks.
- AR collections (week 8-10). Aged receivables drop because someone's actually calling.
- Vendor calls and supplies coordination (week 10-12). Truck stock issues stop being a daily fire.
Each handoff gets a documented process. Not a 20-page SOP, just a one-page how-we-do-this. The documentation forces you to actually decide how you want it done, which is its own benefit.
Make the decision.
- Today: count how many of the four signals are true for your shop right now.
- If three or more: draft the role description using the scope above. Aim for $22-30/hr (Ontario range for an organized admin role) plus the burden math from the labour rate article.
- This month: post the role. Interview for personality first, skills second. Reference-check rigorously.
- Before they start: write the 90-day plan. Make their first two weeks a real shadowing period, not a "figure it out" period.
