Customer screening: the red flags to catch before you take the job

The bad job you saw coming and took anyway

Every trade has one. The job you knew was trouble the second the phone rang, and you took it anyway, because work is work and the truck payment doesn’t care about your feelings. The customer nitpicked every line on the quote. Then argued the invoice. Then left a one-star that had nothing to do with the quality of the work. And here’s the part that stings: you knew. The signs were all over that first call. You just wanted the job more than you wanted to listen.

Screening customers has nothing to do with being picky or acting like you’re too good for the work. It’s about money. A bad customer costs you more than one rough afternoon. He costs you the hours on the phone, the deposit you never thought to ask for, the review that scares off three good jobs, and the profit from two clean ones you could’ve run instead. Spotting him early is one of the highest-paid skills in this business, and nobody ever teaches it.

The tells on the first call

Most red flags show up before you ever leave the shop. You just have to be listening for them, instead of hearing the word “money” and stopping there.

• Leads with price. They want your cheapest number before they've even told you what's actually wrong. Somebody shopping on price alone will leave you the day a cheaper truck pulls up.
• Runs down every contractor who came before you. If the last three guys were all crooks and idiots, do the math on where that leaves you.
• Won't let you look. Demands a firm price sight unseen, then gets cagey when you offer to come out and see the job in person.
• Haggles a number that doesn't exist yet. If they're negotiating before you've even quoted, the fight over the final bill is already on the calendar.

None of these is a dealbreaker on its own. A guy can ask about price and still turn out to be the best customer you get all year. But when two or three of them stack up on the same call, that’s a pattern, and the pattern usually holds right through to the last payment.

What shows up at the estimate

Then you drive out to look, and the job starts telling you things the customer didn’t.

There’s the half-finished work the last contractor walked away from. Ask yourself why he walked. Sometimes the job was over his head. Just as often, it was the person standing next to you. Watch for the customer who won’t put anything in writing, or the one who’s already changed his mind twice while you’re standing in the room. And really watch the one who slips a word like “lawyer” or “chargeback” into friendly conversation, like it’s a normal thing that happens to regular people.

And watch the money talk closest of all. “I’ll pay you when it’s done and I’m happy” sounds reasonable right up until you sit with it. Happy is a moving target, and the customer is the one holding it. No deposit, everything due at the end, payment hooked to a feeling instead of the finished work. Congratulations, you’re the bank now, and the loan has no due date.

“"I'll pay you when I'm happy" isn't a payment plan. It's a moving target, and the customer holds the goalposts.

Your gut is data. Check it anyway.

Sometimes there’s no single flag you can point to. Just a knot in your stomach that says don’t. Listen to it. That feeling is every job you’ve ever run, adding itself up into a warning you can’t quite put into words yet.

You don’t have to run on the feeling alone, though. Test it. Ask for a fair deposit and watch what the customer does with it. A good one pays without a fuss, because he gets that you have materials to buy and a business to keep running. Somebody who acts insulted by a normal deposit just showed you exactly how the final payment is going to go. That one move screens out more bad jobs than any hunch ever will.

Give people a little room, too. A customer who got torched by a bad contractor last year might come off prickly and suspicious, and nine times out of ten he isn’t scheming, he’s just been burned and it still shows. The skill is telling scared apart from scheming. Scared settles down the minute you’re straight with him and prove you know your trade. Scheming just goes looking for a new angle.

Walk away, or price for the trouble

Once you’ve spotted it, you’ve got two honest moves, and both beat gritting your teeth through a job you already regret.

You can pass. “I don’t think I’m the right fit for this one, but I hope you get it sorted.” No lecture, no burned bridge, just a clean no. Turning down money will always feel wrong in the moment. It feels a whole lot better than the three weeks you’d have spent regretting the yes.

Or you take it with your eyes open and price for the risk. Bigger deposit. Progress payments, so you’re never more than a few hundred dollars out of pocket at any point. Every line of the scope written down and signed before you start. If a customer is going to eat three hours of your week in phone calls and hand-holding, that time belongs in the number. Charge for it, and one of two good things happens: the job turns into decent money, or he goes off to find somebody cheaper to torture.

Where a CRM earns its keep

Screening isn’t a one-time thing you do on the first call and forget. It’s a habit, and a habit needs somewhere to live. That problem customer you swore you’d never take again is easy to forget by next spring, right up until his name lands back on your schedule and it all comes flooding back. Write it down while it’s fresh.

That’s a good chunk of what a real CRM does for you. ToolbagCRM keeps the full history on every customer, so the note you left last year, slow to pay, argues every invoice, deposit required, is sitting right there the next time that number calls in. It lets you require a deposit before the job ever hits the calendar, and send an estimate the customer signs from his phone, so the scope is locked down before anybody turns a wrench. The whole crew, office and field, runs on one flat price with no per-seat charge, so the tool that protects your margin isn’t quietly eating it. Founders pricing is $99/mo for your first three months, then $150/mo locked for the life of the account.

You’ll never screen out every bad job. One slips through now and then, and that’s the cost of doing business with the public. But a perfect record was never the goal. The goal is to stop letting the worst handful of customers eat the profit you earned on all the good ones. Catch most of them at the door, and the whole year runs a little easier.
