You're the spouse, kid, lead tech, or admin who actually drives the computer at the shop. He won't use anything new unless it works on Day 1. This checklist gets you from zero to a paid customer invoice in 20 minutes flat — so by the time he sees it, the proof is already in his pocket.
Do these in order. Print the page if it helps. By step 8, his actual customer has paid an actual invoice through an actual app — and that's an argument that ends itself.
Use his business email if he has one. The account belongs to the business; you're the operator helping him set it up.
"Service call $89", "Diagnostic $109", "Capacitor $185 installed", whatever his normal list is. You probably already have these memorized.
Paste them in from his customer list, his last invoice book, his phone contacts — wherever they live. The app accepts any common format. 30 is enough to make it real; you don't need them all.
Stripe Connect walks you through it — name, business address, bank routing + account. Standard small-business KYC. He'll need to enter his SSN himself for the verification (don't do this part for him).
"Test call, fake address, $1 service charge." Click send. You'll get the invoice in your own email. Pay it with your real card (it's only $1). Watch the dollar land in his Stripe balance.
Click refund on the test invoice. The $1 goes back to your card. Now you've proven both directions work.
The next call he picks up the phone for — type it into LMH while he talks to the customer. Customer name, address, problem description. Three fields.
"This is the next call. The customer's history is loaded. Hit send when you're done — the invoice goes to her email." That's the moment he gets it.
Total: 20 minutes. Result: a paid real invoice in his bank account.
He's been doing HVAC 20+ years and he's good at it. What he's not good at is sitting at a computer for 30 minutes deciding if new software is worth it. That's your specialty. Here's what's in it for the shop:
Invoices get sent from the truck and paid before he leaves the driveway. No more "I'll mail you a check" that becomes 60-day net.
One system. No more paper invoice book + QuickBooks + texting receipts. QuickBooks sync coming Q2 2026 will close the last loop.
Customer history is one tap away. No more digging through the paper file box on the third trip out.
