One blended margin
All revenue in one line, all costs in another. The kitchen reno that lost $6k and the panel upgrade that made $9k average out to "fine," and you keep bidding both.

Know which jobs actually made money.
A full calendar and an empty account usually means a few jobs lost money and nobody could see it. We code materials, subs, labour and site costs to each job as they land, keep holdbacks and progress billing straight, and handle the T5018 and WSIB paperwork that comes with crews.

Where trade books go wrong
Three ways profitable trades go broke on paper.
Busy is not the same as profitable. These are the three gaps that hide the difference.
Holdbacks in limbo
10% of every billing sits unpaid by design. Untracked, it's revenue you forget you're owed, and HST that gets remitted in the wrong period, or twice.
Holdbacks receivable, HST timed right
Subs with no paper trail
E-transfers to subcontractors all year, then a scramble when the T5018 return is due and WSIB asks for clearance certificates you never collected.
Sub payments tracked all year
Every job, its own little P&L.
Materials, subs and labour coded to the job they belong to, as they happen.
The number that changes your bidding
One job, costed honestly.
When every receipt, sub invoice and crew hour lands on the right job, the P&L stops being a mystery. You see which job types, which customers and which price points actually carry the business, while there's still time to bid differently.
We set this up in QuickBooks Projects and keep it fed from your bank, supplier invoices and payroll, no extra admin on your side.

Trades FAQ
The questions that come up first.
If construction is your main business and you pay subcontractors, the CRA requires an annual T5018 information return reporting what you paid each one. We track sub payments all year, so the slips are a button-press, not an archaeology project.
Ontario's Construction Act lets customers hold back 10% of each billing until lien periods expire. It's earned revenue you can't collect yet, and the HST on it generally isn't collectible until the holdback becomes payable. We track holdbacks as their own receivable so the cash and the HST both land in the right period.
Yes, that's the point. Costs are coded to each job as they happen, so every month you see margin by project, not one blended number. Bidding gets easier when you know which kinds of jobs actually make money.
Pricing is one flat monthly fee, quoted after a free review of your books depending on job volume, sub count and payroll. QuickBooks with project tracking, reconciliation, HST filing and job-cost reporting are included.
