6 worked Annual Bookkeeping 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 annual bookkeeping work, not a specific client's file.
Case Study 1 · Scaling without breaking
Growth Handled Without A Missed Filing, $58,000 Freed — Equipment Rental Yard, Vancouver
Client: An equipment rental yard · Where: Vancouver, British Columbia · Engagement: 4 weeks, fixed fee
Cash freed$58,000
Compliance failuresNone
ReportingMonthly
The situation — An equipment rental yard, Vancouver, British Columbia
An equipment rental yard in Vancouver, British Columbia was opening in a second province. That meant different filing obligations and a different payroll regime. Eighteen months of unreconciled transactions and a shoebox of receipts already sat in the file.
What we did for An equipment rental yard, Vancouver, British Columbia
We rebuilt the ledger from bank and card statements and matched every receipt to a transaction. We removed duplicated input tax credits before they became a review. 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 — An equipment rental yard, Vancouver, British Columbia
Growth was absorbed without a compliance failure. $58,000 of cash was released, and the monthly reporting now flags a problem while it is still small.
Case Study 2 · Objection and relief
Desk-Review Assessment Of $39,500 Vacated — Home-Renovation Contractor, Brampton
The situation — A home-renovation contractor, Brampton, Ontario
A home-renovation contractor in Brampton, Ontario was carrying $39,500 of penalties and interest. The charges arose from sales recorded from bank deposits, so processor fees, chargebacks and refunds appeared nowhere in the ledger. Much of that amount accumulated during a period the CRA itself had delayed.
What we did for A home-renovation contractor, Brampton, Ontario
We cleared the payroll and sales tax clearing accounts every month and tied each remittance to the liability it settled. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
The result — A home-renovation contractor, Brampton, Ontario
The assessment was vacated. $39,500 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 3 · CRA review defended
$38,000 Proposed Adjustment Withdrawn In Full — Courier Subcontractor, Toronto
Client: A courier subcontractor paid by the drop · Where: Toronto, Ontario · Engagement: 10 weeks, fixed fee
Adjustment withdrawn$38,000
File closed in10 weeks
Penalties assessedNone
The situation — A courier subcontractor paid by the drop, Toronto, Ontario
A courier subcontractor paid by the drop in Toronto, Ontario received a proposal letter opening a review of annual bookkeeping. The CRA had identified a bookkeeping file where owner draws, payroll and supplier payments all landed in the same account. It proposed an adjustment of $38,000, with 30 days to respond.
What we did for A courier subcontractor paid by the drop, Toronto, Ontario
We treated the response as an evidence exercise rather than an argument. We converted the foreign-currency purchases at transaction-date rates and recorded the exchange difference at settlement instead of burying it in cost of sales. We then indexed every supporting document against the specific line the auditor had questioned.
The result — A courier subcontractor paid by the drop, Toronto, Ontario
The proposed adjustment was withdrawn in full — all $38,000 of it. The file closed in 10 weeks with no change to the assessed amounts and no penalty.
Case Study 4 · Deadline rescue
$73,000 Late-Filing Penalty Cancelled On Relief Application — Owner-Operated Trades Business, London
Client: An owner-operated trades business · Where: London, Ontario · Engagement: 4 weeks, fixed fee
Penalty cancelled$73,000
Relief applicationGranted
ReturnAccepted as filed
The situation — An owner-operated trades business, London, Ontario
An owner-operated trades business in London, Ontario had already missed one deadline and was about to miss a second. Behind it sat a payroll clearing account that had never been brought to zero, carrying a balance nobody could explain. A penalty of $73,000 was accruing.
What we did for An owner-operated trades business, London, Ontario
We split the work into what had to happen before the deadline and what could follow it. Then we recoded the meals and entertainment accounts to the statutory limit and reversed the over-claimed input tax credits before the next return went in.
The result — An owner-operated trades business, London, Ontario
The outstanding return was accepted as filed, and the taxpayer relief application cancelled $73,000 of the penalty already assessed on the earlier year.
Case Study 5 · Missed incentive claimed
Incentive Review Recovered $24,000 Across 5 Open Years — Small Law Practice, Guelph
Client: A small law practice · Where: Guelph, Ontario · Engagement: 3 weeks, fixed fee
Recovered$24,000
Open years claimed5
Ongoing trackingIn place
The situation — A small law practice, Guelph, Ontario
An incentive review at a small law practice in Guelph, Ontario started from a simple question: what has never been claimed? The answer ran to 5 years. It was driven by sales recorded from bank deposits, so processor fees, chargebacks and refunds appeared nowhere in the ledger.
What we did for A small law practice, Guelph, Ontario
We rebuilt sales from the processor settlement reports so gross sales, fees and refunds each landed in an account of their own. We documented eligibility to the standard a reviewer would apply rather than the standard a claim form requires.
The result — A small law practice, Guelph, Ontario
The credits produced $24,000 across the open years. The tracking now in place means the following year's claim is documented as the work happens rather than reconstructed afterwards.
Case Study 6 · Records and systems rebuilt
Books Rebuilt From Source, $3,900 In Unclaimed Input Tax Found — Wedding Photography Studio, Halifax
Client: A wedding photography studio · Where: Halifax, Nova Scotia · Engagement: 4 weeks, fixed fee
Unclaimed tax found$3,900
Records rebuilt25 months
ProcessDocumented
The situation — A wedding photography studio, Halifax, Nova Scotia
A wedding photography studio in Halifax, Nova Scotia could not answer basic questions about its own numbers. Input tax credits claimed on receipts that had already been claimed once sat between the bank statements and the ledger.
What we did for A wedding photography studio, Halifax, Nova Scotia
We reconciled receivables and payables to source documents and wrote off the balances that were genuinely uncollectible, with support. We then documented the process so the work does not depend on any one person remembering how it was done.
The result — A wedding photography studio, Halifax, Nova Scotia
Records rebuilt and reconciled, $3,900 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
