Two numbers per project, and the honest one comes last
The estimate margin is a plan; the post-punch-list margin is a fact, and the distance between them is the most useful number in the company. We close every project with a review: actual trade costs, crew hours including the return visits, supplier invoices against quoted allowances, change orders billed and unbilled, line by line against the estimate. Do that for a year of projects and the pattern stops being anecdote. Certain project types, certain estimates, certain trades show up as the consistent source of fade, and next year's pricing gets built on what actually happened rather than what was hoped.
Where renovation margin leaks
| Leak | How it happens | The control |
|---|---|---|
| Unpapered change orders | Scope changes agreed at the site door, built, never billed | No change starts without a signed, priced change order |
| Allowance overruns | The client picks tile above the allowance and the difference surfaces after close, or never | Allowances tracked at selection and billed when the choice is made |
| Punch-list labour | Weeks of return visits after the final draw, with no budget line behind them | A punch-list reserve in every estimate; hours coded to the job until it truly closes |
| Long-lead price moves | Cabinet and stone prices shift between the quote and the order | Quote validity windows in the contract; orders placed at signing |
| Warranty callbacks | This year's crew quietly fixing last year's projects | A separate warranty cost line, priced back into future bids |
None of these leaks is exotic. Each is invisible in a books-only view and obvious in a per-project one, which is why the CFO work sits on top of project-level records rather than a single profit line.
Change orders are a finance function
The hallway yes is the most expensive sentence in renovation. A change order priced before the work carries its real cost, the trade quotes, the crew hours with their WSIB and site-insurance burden, the schedule impact, plus margin. A change agreed verbally carries whatever someone can reconstruct at the final invoice, argued with a client who remembers it smaller. The discipline is procedural, and finance owns enforcing it: every change priced, signed and scheduled before material is ordered, billed with the next stage draw rather than parked for the end, and synced from Houzz Pro or Buildertrend into the books so change revenue is visible per project instead of folded into the base contract. Owners are often surprised which way their change-order margin runs once it is measured at all.
Cash that looks bigger than it is
A renovator's bank balance flatters. Inside it sit deposits for stages not yet built, money already promised to the cabinet shop, trade invoices in the approval queue, and HST that was never yours. The CFO view nets that out per project: what each job holds in unearned deposits, what it still needs to finish, and whether the company is quietly using this project's deposit to complete the last one. That pattern is the renovation firm's classic failure. Caught early it is a scheduling and pricing problem; caught late it is a problem with your clients' money. A rolling cash view across signings, stage draws and supplier deposits shows the pinch weeks before it arrives, and when growth genuinely needs outside money, a van fleet, a showroom fit-out, Business Financing Advisory sizes and negotiates the facility.

The funnel, the showroom and the quarterly table
Design retainers are the leading indicator: signed design agreements today are construction starts months from now, so tracking the design funnel tells you about crew load and cash long before the schedule does. The showroom is the other standing question, and it deserves a number: what it costs per year against how many signed contracts genuinely started in it, measured like any other marketing spend. A quarterly sit-down over closed-project margins, the design funnel, the per-project cash position and pricing is where those calls get made. That is what a Fractional CFO engagement looks like for a renovation firm in the GTA: senior finance work at a written, quoted scope, running on the project-level books our End-to-End Accounting service keeps current. Filing what happened is the floor; deciding what happens next is the job.
