6 worked Waterloo 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 Waterloo and its provincial tax regime, not a specific client's file.
Case Study 1 · Planning that cut the bill

Filing positionUnchanged in risk
The situation — A medical imaging clinic, Waterloo, Ontario
A medical imaging clinic in Waterloo, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly. It still left instalments still calculated on a year the business had long outgrown on the table.
What we did for A medical imaging clinic, Waterloo, Ontario
We modelled the current position against the alternatives before changing anything. Then we rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns.
The result — A medical imaging clinic, Waterloo, Ontario
The change saved $22,500 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 · Records and systems rebuilt
18 Months Reconciled And $20,500 Of Input Tax Recovered — Millwork Shop, Waterloo

We rebuilt from source rather than correcting on top of the existing file. We registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty. Then we set the routine that keeps it clean.
The result — A millwork shop, Waterloo, Ontario
18 months reconciled to the bank. The close now takes 10 days, and $20,500 of previously unclaimable input tax was recovered in the process.
