6 worked Internal Controls Review 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 internal controls review work, not a specific client's file.
Case Study 1 · Scaling without breaking
Growth Handled Without A Missed Filing, $47,000 Freed — Business Preparing for Sale, Brampton
Client: A business preparing for sale · Where: Brampton, Ontario · Engagement: 7 weeks, fixed fee

ReportingMonthly
The situation — A business preparing for sale, Brampton, Ontario
A business preparing for sale in Brampton, Ontario was opening in a second province. That meant different filing obligations and a different payroll regime. A prior-year restatement with no note explaining what changed already sat in the file.
What we did for A business preparing for sale, Brampton, Ontario
We prepared a due-diligence-ready statement set with supporting schedules for each material 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.
The result — A business preparing for sale, Brampton, Ontario
Growth was absorbed without a compliance failure. $47,000 of cash was released, and the monthly reporting now flags a problem while it is still small.

The situation — A corporation restating a prior year, Edmonton, Alberta
Nothing was wrong at a corporation restating a prior year in Edmonton, Alberta. The filings were on time and accurate. What they were not was planned. A bonding limit capped because the last statements were prepared on a cash basis had never been reviewed.
What we did for A corporation restating a prior year, Edmonton, Alberta
We described the revenue and inventory policies in the basis-of-accounting note in terms a lender could follow without asking a question. We ran the numbers across both the corporate and personal returns, so the saving was real rather than deferred into someone else's hands.

$55,000 came off the combined corporate and personal tax bill, and the structure holds for future years without further work.

What we did for A company under a bank covenant, Moncton, New Brunswick
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, we prepared the supporting schedule for every material balance in advance, which cut the queries the engagement had to raise.

$82,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.

A contractor bidding on bonded work in Saskatoon, Saskatchewan could not answer basic questions about its own numbers. A bank asking for a review engagement while the file only supported a compilation sat between the bank statements and the ledger.
What we did for A contractor bidding on bonded work, Saskatoon, Saskatchewan
We converted the records to the accrual basis, restated the comparative year with proper disclosure, and rebuilt the statement package around the bonding company’s requirements. We then documented the process so the work does not depend on any one person remembering how it was done.

Records rebuilt and reconciled, $3,000 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
