Here's the brutal truth: Most trade business owners bill only for the "main job."
They lose $10Kβ$20K every single year because they forget to invoice for small, billable tasks that feel
"too minor" to track. The result? You work harder, cover costs out of pocket, and watch your margins shrink.
The following 3 invoices are the ones nearly every electrician, plumber, and GC misses.
Fix these leaks, and you'll add pure profit back to your bottom line β starting tomorrow.
β οΈ The Problem (Scope creep)
"Hey while you're here, could you add an extra outlet?" β sound familiar? Clients casually ask for small additions. Without a written change order, you work for free and blur the final bill. That "5-minute favor" costs you $75β150 each time, and it adds up fast.
β
The Simple Fix
Never touch a modification without written approval (text or email works). Before starting, send a quick estimate for the extra work. Then add a "change order" line to the final invoice. Even better, a smart invoicing tool lets you create & send change orders instantly from your phone.
β οΈ The Problem (Unpaid hours)
You spend 30 minutes driving to the supply yard, 20 minutes waiting for the general contractor, or 15 minutes on hold with a vendor. Many trades don't bill those hours because they feel "unfair" to charge β but every minute is real labor. Over a month, that's 10+ lost hours.
β
The Simple Fix
Use a timer on your phone to log every non-productive work minute (travel, waiting, material pickup). Add them as a separate "Logistics" or "On-Site Coordination" line item. A modern mobile app can track those hidden hours with one tap and turn them into billable entries β painlessly.
β οΈ The Problem (Missing markup)
You pay $100 for a specialized part, toss the receipt in your pocket, and only charge the client exactly $100. You forget your markup (20-30%) and the delivery fee. That's margin you earned but never collected. Over a year, it could be thousands in lost profit.
β
The Simple Fix
Always add 25% material markup OR a fixed delivery/handling fee ($15β$25) on every invoice. Use an expense tracker that lets you snap a photo of the receipt, auto-suggest markup, and add it to the invoice instantly. No more pocket receipts β just healthy margins.
β‘ The smarter way one tool fixes all three
Manually tracking change orders, hidden hours, and material markups is tedious. But what if you could capture every billable moment from your phone, and turn it into a professional invoice in seconds β without missing a dollar?
