So you finally did it. The truck has your name on it, the first invoices are going out, and the phone keeps ringing. Then the paperwork starts piling up, and somewhere between the job site and the dinner table you realize you have no idea whether you are actually making money or just staying busy.
You are not alone. Every first-year electrician, plumber, HVAC tech, and renovator in BC hits this wall. The good news is that the basics are not complicated. They are just easy to ignore until the numbers stop making sense. Here is what you actually need to track from day one, in plain language, so a young trade business never gets blindsided by its own books.
What "keeping the books" really means for a trade
Bookkeeping is not busywork for accountants. It is the record of every dollar that comes in, every dollar that goes out, and where each one went. When it is done right, you can answer three questions at any moment: Am I profitable, do I have cash to pay what is coming, and what do I owe the government?
For a trades business, that last question matters more than most owners expect. Running a crew means payroll, and payroll means statutory deductions and remittances. Selling in BC means GST and PST. Hiring means WorkSafeBC coverage. Miss any of those and the penalties land before the profit does.
The five things to track from day one
You do not need to be a finance person. You need a simple system that captures five things consistently.
1. Every dollar in and out
Start with reconciliation. Every month, match your bank and credit card statements line by line to your records. It sounds basic because it is. It is also the single habit that catches double charges, missed deposits, and that one supplier invoice you forgot about.
If your books are reconciled, you always know your real cash position. If they are not, you are guessing, and guessing is what makes a profitable month feel like a scary one.
2. Job costing, so you know which work pays
This is the one most new contractors skip, and it is the one that costs the most. Job costing means tracking the labor, materials, and subcontractor costs against each job, then comparing them to what you charged.
Do it and you learn that your Tuesday renovation jobs are your bread and butter while a certain type of custom work quietly loses money. Skip it and you can run a full season without ever knowing which half of your business is actually carrying the other half.
3. Payroll and source deductions
The moment you hire your first employee, you are on the hook for source deductions: CPP, EI, and income tax withheld from their pay. You collect these on the government's behalf and remit them on a schedule. This is not optional money, and it is not yours to hold onto.
Payroll also means keeping clean records of hours, rates, vacation pay, and each remittance. When this is handled properly, your crew gets paid correctly and you never open a letter from the CRA with a knot in your stomach.
4. GST, PST, and WorkSafeBC
Three obligations catch first-year BC contractors off guard:
- GST and PST. Once you pass the small-supplier threshold, you charge GST on most sales and PST on many materials. You hold that money in trust and remit it. It was never profit, and treating it as cash flow is one of the fastest ways to get into trouble.
- WorkSafeBC. If you have workers, you register, report your payroll, and pay premiums. Getting the classification and reporting right keeps your coverage valid and your costs predictable.
- Remittance deadlines. Each of these has its own schedule. Missing one triggers interest and penalties that eat straight into your margin.
5. Receipts and records, kept simple
Every deduction you claim needs a record behind it. Fuel, tools, materials, vehicle expenses, insurance, the lot. A phone photo of a receipt sent to a dedicated folder takes ten seconds and saves hours later. Clean records are also what let a bookkeeper move fast on your behalf, which keeps your bill lower.
The mistakes that cost first-year contractors the most
Most new trade owners do not get into trouble because they spend too much. They get into trouble because they cannot see what is happening until it is too late. The patterns are predictable:
- Mixing personal and business spending in one account, which makes every month harder to untangle.
- Treating GST and payroll withholding as money you get to spend.
- Waiting until tax season to look at the numbers, when every fix is already expensive.
- Setting prices with no idea what a job actually costs to deliver.
None of these are character flaws. They are just what happens when a skilled tradesperson is forced to become an accountant overnight, with no time and no training.
When to bring in help
You can absolutely handle the basics yourself for a while. The question is when the cost of staying on top of it starts to outweigh the cost of handing it off.
A good rule of thumb: the moment you are running a small team and doing real revenue, bookkeeping stops being a chore and starts being a decision-making tool. That is the point where the right help pays for itself, because it tells you which jobs to chase, what you can safely pay yourself, and what you owe the CRA before the deadline instead of after.
