Starting a trades business, 9 habits that keep every job profitable

Being good at the trade is the start. Running a profitable trades business takes a few business habits, and they're easiest to build when you're small. These apply whether you're a plumber, an electrician, an HVAC tech or a roofer.
1. Know your real cost per hour
Add up what it actually costs to run the business each month (truck, insurance, tools, phone, software, your own pay), then divide by the hours you can realistically bill. That number is your floor. Price below it and every job loses money, however busy you are.
2. Build a price list, even a rough one
A price list makes quoting faster and more consistent. Start with your common jobs and materials, and refine it as you go. Customers trust consistent prices, and so do the people you hire.
3. Quote fast, and quote in writing
The first clear written quote often wins. Send it the same day if you can, with what's included and what isn't, and make it easy to approve.
4. Take deposits on bigger jobs
A deposit covers materials and filters out customers who aren't serious. Put the payment schedule in writing on every quote.
5. Photograph your work
Before and after photos protect you in disputes, support warranty and insurance claims, and become your best marketing. Keep them on the job, not scattered across phones.
6. Write down every change
"While you're here, can you also..." is how margins disappear. Price the change and get a yes in writing before doing it.
7. Keep business money separate
Open a business bank account and keep business money in it. It makes taxes simpler, and if you form an LLC, keeping finances separate is part of what protects your personal assets. Talk to an accountant early. It costs less than fixing a mess later.
8. Get paid on completion, not "when they get around to it"
Send the final invoice the day the job is done, and make it easy to pay by card or bank transfer. The longer an invoice sits, the less likely it gets paid in full.
9. Make the customer experience your advantage
Show up when you say, tell customers what's happening, clean up, and ask for a review when you're done. In the trades, reputation is the cheapest marketing there is.
Guildmark helps with most of these out of the box: a price list per trade, quotes customers sign on their phone, photos on every job, change notes that stay with the job, and (soon) deposits and payments. It's free to start, with unlimited users. Join the waiting list.
