6 worked Department Profitability Analysis case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to department profitability analysis work, not a specific client's file.
Case Study 1 · Deadline rescue
Filed On Time From A Standing Start, $43,000 Penalty Avoided — Mid-Sized Services Firm, Guelph
Client: A mid-sized professional services firm. Where: Guelph, Ontario. Engagement: 10 weeks, fixed fee.
Penalty avoided$43,000
Turnaround10 weeks
FiledOn time
Case 1: the situation
A mid-sized professional services firm in Guelph, Ontario came to us 10 weeks before its filing deadline. The file came with a growth plan with no forecast behind it and no financing lined up. A late filing would have triggered a penalty of roughly $43,000 before interest.
Case 1: what we did
We worked backwards from the deadline. We separated customer prepayments from earned revenue in the reporting, so the cash position and the tax position were visible at the same time. We prioritised the items that actually gated the filing and deferred everything that did not.
Case 1: the result
The return was filed on time and complete. The $43,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 2 · Records and systems rebuilt
Books Rebuilt From Source, $16,000 In Unclaimed Input Tax Found — Expanding Manufacturer, Vancouver
Client: A manufacturer planning a plant expansion. Where: Vancouver, British Columbia. Engagement: 9 weeks, fixed fee.
Unclaimed tax found$16,000
Records rebuilt31 months
ProcessDocumented
Case 2: the situation
A manufacturer planning a plant expansion in Vancouver, British Columbia could not answer basic questions about its own numbers. A covenant breach discovered only when the bank called sat between the bank statements and the ledger.
Case 2: what we did
We traced each borrowing to what it actually funded and kept the interest deduction on the portion used to earn business income. We then documented the process so the work does not depend on any one person remembering how it was done.
Case 2: the result
Records rebuilt and reconciled, $16,000 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Case Study 3 · Cash and remittance control
Instalments Rebased, $72,000 Of Cash Returned To The Business — Fast-Growing E-Commerce Brand, Winnipeg
A fast-growing e-commerce brand in Winnipeg, Manitoba was paying instalments calculated on a prior year. That year no longer reflected the business. Revenue up 40% year over year and a bank balance that kept falling was tying up $72,000 of cash.
Case 3: what we did
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, we added the balance sheet and a cash view to the monthly package, so the owner saw working capital move rather than only profit.
Case 3: the result
$72,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
Case Study 4 · Planning that cut the bill
$67,000 Saved By Correcting What Prior Filings Had Missed — Practice Adding Partners, Saskatoon
Client: A professional practice adding partners. Where: Saskatoon, Saskatchewan. Engagement: 9 weeks, fixed fee.
Saving identified$67,000
RecurringYes
Positions documentedAll
Case 4: the situation
A professional practice adding partners in Saskatoon, Saskatchewan asked for a second opinion on department profitability analysis. That followed three years of rising tax. The review found a borrowing drawn for an unrelated personal purchase with the interest claimed against the business.
Case 4: what we did
We built the comparison first: current structure against two alternatives. Then we set a quarterly tax provision, so the instalments and the year-end balance were funded before they came due.
Case 4: the result
First-year saving of $67,000, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 5 · Scaling without breaking
Growth Handled Without A Missed Filing, $140,000 Freed — Contractor Scaling Bids, Regina
Client: A construction company bidding larger contracts. Where: Regina, Saskatchewan. Engagement: 10 weeks, fixed fee.
Cash freed$140,000
Compliance failuresNone
ReportingMonthly
Case 5: the situation
A construction company bidding larger contracts in Regina, Saskatchewan was opening in a second province. That meant different filing obligations and a different payroll regime. A healthy bank balance made up almost entirely of deposits for work not yet performed already sat in the file.
Case 5: what we did
We built a rolling thirteen-week cash-flow model, tightened collections, and renegotiated supplier terms so the growth stopped consuming the bank balance. We then put monthly reporting in place. That let the owner see the cash effect of growth while there was still time to act on it.
Case 5: the result
Growth was absorbed without a compliance failure. $140,000 of cash was released, and the monthly reporting now flags a problem while it is still small.
Case Study 6 · CRA review defended
$88,000 Proposed Adjustment Withdrawn In Full — Subscription Business, Windsor
Client: A subscription business tracking churn. Where: Windsor, Ontario. Engagement: 8 weeks, fixed fee.
Adjustment withdrawn$88,000
File closed in8 weeks
Penalties assessedNone
Case 6: the situation
A subscription business tracking churn in Windsor, Ontario received a proposal letter opening a review of department profitability analysis. The CRA had identified an owner making hiring decisions on last quarter’s bank balance. It proposed an adjustment of $88,000, with 30 days to respond.
Case 6: what we did
We treated the response as an evidence exercise rather than an argument. We rebuilt the reporting around gross margin by service line, which showed two of five offerings were losing money at the current price. We then indexed every supporting document against the specific line the auditor had questioned.
Case 6: the result
The proposed adjustment was withdrawn in full — all $88,000 of it. The file closed in 8 weeks with no change to the assessed amounts and no penalty.
