If you're a contractor — electrician, plumber, HVAC tech, roofer, or general trades business — bookkeeping is usually the last thing on your mind.
You're focused on jobs, crews, materials, and getting paid. And bookkeeping? It gets pushed to "later." That's where problems start.
Why Bookkeeping Is Harder for Trades Businesses
Trades businesses are not like typical service businesses. You're dealing with:
- Multiple jobs at once
- Cash + e-transfer + invoices
- Material purchases across suppliers
- Subcontractors and labour costs
Which means your numbers get messy fast.
The Most Common Bookkeeping Mistakes (Trades)
1. Mixing Personal & Business Spending
Using one account for everything leads to missed deductions, confusion at tax time, and CRA risk.
2. Not Tracking Job Costs Properly
Most contractors don't track materials per job, labour per job, or actual profit per project. So you don't know which jobs are actually making money.
3. Falling Behind Monthly
"Catch up later" turns into months of backlog, inaccurate numbers, and stress at tax time.
4. GST Confusion
Trades businesses often collect GST but don't set it aside, and forget to claim input tax credits. This leads to surprise tax bills.
5. No Clear Profit Visibility
You might be busy — but are you profitable? Without proper books, you're guessing.
What Good Bookkeeping Looks Like (Simple System)
You don't need anything complicated. You need consistency.
-
Separate Accounts
Get a business bank account and a business credit card. Keep them separate from personal finances.
-
Track Monthly (Not Year-End)
Categorize expenses, reconcile accounts, and review cash flow every month.
-
Job-Level Tracking (Game Changer)
Know your job revenue, material costs, labour, and profit per project. This is how real businesses scale.
-
Stay GST-Ready
Track GST collected vs paid. Avoid surprises at remittance time.
Why This Matters
Good bookkeeping helps you:
- Know your real profit
- Avoid CRA issues
- Price jobs properly
- Grow with confidence
Final Thought
Most trades businesses don't fail because of lack of work. They struggle because the numbers aren't clear. Fix the numbers — and everything else gets easier.
