6 worked Small Business 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 small business bookkeeping work, not a specific client's file.
Case Study 1 · Planning that cut the bill
$64,000 Cut From The Annual Tax Bill — Dental Hygiene Clinic, London
A dental hygiene clinic in London, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left input tax credits claimed on receipts that had already been claimed once on the table.
Case 1: what we did
We modelled the current position against the alternatives before changing anything. Then we set up a documented chart of accounts, a receipt-capture workflow and a monthly reconciliation that closes within ten days of month-end.
Case 1: the result
The change saved $64,000 in the first year and repeats annually. Nothing about the filings became more aggressive. The position is simply the one the rules already allowed.
Case Study 2 · Cash and remittance control
Instalments Rebased, $61,000 Of Cash Returned To The Business — Two-Location Cafe, Calgary
A two-location cafe in Calgary, Alberta was paying instalments calculated on a prior year. That year no longer reflected the business. A receivables list that included invoices collected eleven months earlier was tying up $61,000 of cash.
Case 2: what we did
We rebased the instalments on the current-year estimate rather than the prior-year default. Alongside that, 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.
Case 2: the result
$61,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.
Case Study 3 · Records and systems rebuilt
Month-End Close Cut From 8 Weeks To 6 Days — Mobile Pet-Grooming Company, Kitchener
Client: A mobile pet-grooming company. Where: Kitchener, Ontario. Engagement: 5 weeks, fixed fee.
Close time before8 weeks
Close time after6 days
Year-endReview, not rebuild
Case 3: the situation
The accounting file at a mobile pet-grooming company in Kitchener, Ontario had a weak foundation. It was built on a payroll clearing account that had never been brought to zero, carrying a balance nobody could explain. The year-end had taken 8 weeks each of the last three years.
Case 3: what we did
We reconciled receivables and payables to source documents and wrote off the balances that were genuinely uncollectible, with support. We also moved the reconciliations into the monthly cycle, so the year-end stopped being a rebuild.
Case 3: the result
The file reconciles. Month-end closes in 6 days instead of 8 weeks, and the year-end is a review rather than a reconstruction.
Case Study 4 · Deadline rescue
Filed On Time From A Standing Start, $70,000 Penalty Avoided — Equipment Rental Yard, Ottawa
An equipment rental yard in Ottawa, Ontario came to us 7 weeks before its filing deadline. The file came with a bookkeeping file where owner draws, payroll and supplier payments all landed in the same account. A late filing would have triggered a penalty of roughly $70,000 before interest.
Case 4: what we did
We worked backwards from the deadline. 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 prioritised the items that actually gated the filing and deferred everything that did not.
Case 4: the result
The return was filed on time and complete. The $70,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 5 · Objection and relief
Desk-Review Assessment Of $20,500 Vacated — Home-Renovation Contractor, Moncton
Client: A home-renovation contractor. Where: Moncton, New Brunswick. Engagement: 7 weeks, fixed fee.
Assessment vacated$20,500
Supporting recordsNow on file
AccountCleared
Case 5: the situation
A home-renovation contractor in Moncton, New Brunswick was carrying $20,500 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.
Case 5: what we did
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. We framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
Case 5: the result
The assessment was vacated. $20,500 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 6 · Structure rebuilt
Corporate Structure Rebuilt For $30,000 Of Annual Savings — Courier Subcontractor, Halifax
Client: A courier subcontractor paid by the drop. Where: Halifax, Nova Scotia. Engagement: 8 weeks, fixed fee.
Saving per year$30,000
DocumentationComplete
Transfer basisRollover
Case 6: the situation
The structure at a courier subcontractor paid by the drop in Halifax, Nova Scotia dated from years earlier. It had been set up for a business that no longer existed. Eighteen months of unreconciled transactions and a shoebox of receipts had become expensive.
Case 6: what we did
We separated the owner’s personal spending out of the corporate accounts and cleared the resulting shareholder loan properly. The reorganisation used the rollover provisions rather than a taxable transfer, so no tax fell due on the restructuring itself.
Case 6: the result
$30,000 of annual saving, achieved on a tax-deferred basis. The minute book, elections and valuations are all in the file.
