E-Commerce Case Studies

6 worked E-Commerce 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 e-commerce work, not a specific client's file.

Case Study 1 · Scaling without breaking

Second-Province Expansion Handled, $107,000 Of Cash Released — Supplements Brand, Kelowna

Client: A supplements brand  ·  Where: Kelowna, British Columbia  ·  Engagement: 3 weeks, fixed fee

The situation — A supplements brand, Kelowna, British Columbia

Revenue at a supplements brand in Kelowna, British Columbia was up sharply and cash was tighter than ever. Underneath it sat equipment and asset classes assigned by guesswork rather than the CCA schedule.

What we did for A supplements brand, Kelowna, British Columbia

We reassigned the asset classes on the CCA schedule and corrected the opening balances. Every new obligation — registration, remittance frequency, provincial filing — was set up before it was triggered, not after.

The result — A supplements brand, Kelowna, British Columbia

The situation — A consumer electronics reseller, Red Deer, Alberta

A consumer electronics reseller in Red Deer, Alberta asked for a second opinion on e-commerce accounting and tax after three years of rising tax. The review found seasonal revenue reported without matching the costs that produced it.

What we did for A consumer electronics reseller, Red Deer, Alberta

We built the comparison first — current structure against two alternatives — and then aligned the reporting calendar with the sector’s own seasonal cycle rather than a generic year-end.

The result — A consumer electronics reseller, Red Deer, Alberta

First-year saving of $43,000, with the same benefit recurring. Every position taken is documented and supported in the file.

Case Study 3 · Cash and remittance control

Cash returned$44,000
Instalment basisCurrent year
ReviewedQuarterly

The situation — A pet products retailer, London, Ontario

A pet products retailer in London, Ontario was paying instalments calculated on a prior year that no longer reflected the business. Sector deductions claimed on a general-business basis rather than the e-commerce rules was tying up $44,000 of cash.

What we did for A pet products retailer, London, Ontario

We rebased the instalments on the current-year estimate rather than the prior-year default, and documented the positions to the standard the CRA applies to this sector specifically.

The result — A pet products retailer, London, Ontario

$44,000 of cash stayed in the business, the penalty cycle ended, and the instalment position is reviewed each quarter against actual results.

Case Study 4 · Records and systems rebuilt

Month-End Close Cut From 6 Weeks To 6 Days — Direct-To-Consumer Apparel Brand, Winnipeg

Client: A direct-to-consumer apparel brand  ·  Where: Winnipeg, Manitoba  ·  Engagement: 6 weeks, fixed fee

Close time before6 weeks
Close time after6 days
Year-endReview, not rebuild

The situation — A direct-to-consumer apparel brand, Winnipeg, Manitoba

The accounting file at a direct-to-consumer apparel brand in Winnipeg, Manitoba was built on a chart of accounts that told the owner nothing about e-commerce margin. The year-end had taken 6 weeks each of the last three years.

What we did for A direct-to-consumer apparel brand, Winnipeg, Manitoba

We reviewed every sector-specific deduction against the current rules and claimed the ones that had been missed and moved the reconciliations into the monthly cycle, so the year-end stopped being a rebuild.

The result — A direct-to-consumer apparel brand, Winnipeg, Manitoba

The file reconciles. Month-end closes in 6 days instead of 6 weeks, and the year-end is a review rather than a reconstruction.

Case Study 5 · Deadline rescue

Filed On Time From A Standing Start, $67,000 Penalty Avoided — Amazon FBA Seller, Calgary

Client: An Amazon FBA seller  ·  Where: Calgary, Alberta  ·  Engagement: 5 weeks, fixed fee

Penalty avoided$67,000
Turnaround5 weeks
FiledOn time

The situation — An Amazon FBA seller, Calgary, Alberta

An Amazon FBA seller in Calgary, Alberta came to us 5 weeks before its filing deadline with industry-specific reporting obligations nobody had flagged. A late filing would have triggered a penalty of roughly $67,000 before interest.

What we did for An Amazon FBA seller, Calgary, Alberta

We worked backwards from the deadline. We rebuilt the chart of accounts around how a e-commerce business actually earns and spends, prioritising the items that actually gated the filing and deferring everything that did not.

The result — An Amazon FBA seller, Calgary, Alberta

The return was filed on time and complete. The $67,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.

Case Study 6 · Objection and relief
