6 worked Guelph 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 Guelph and its provincial tax regime, not a specific client's file.
Case Study 1 · Records and systems rebuilt
Books Rebuilt From Source, $16,500 In Unclaimed Input Tax Found — Plastics Moulder, Guelph
The situation — A plastics moulder, Guelph, Ontario
A plastics moulder in Guelph, Ontario could not answer basic questions about its own numbers, because a provincial payroll levy that had never been registered for or remitted sat between the bank statements and the ledger.
What we did for A plastics moulder, Guelph, Ontario
We assessed and claimed Ontario Innovation Tax Credit alongside the federal return, then documented the process so the work does not depend on any one person remembering how it was done.
The result — A plastics moulder, Guelph, Ontario
Records rebuilt and reconciled, $16,500 recovered in input tax credits that the old file could not support, and a documented monthly process now in place.
Case Study 2 · Scaling without breaking
Second-Province Expansion Handled, $58,000 Of Cash Released — Electronics Assembler, Guelph
The situation — An electronics assembler, Guelph, Ontario
Revenue at an electronics assembler in Guelph, Ontario was up sharply and cash was tighter than ever. Underneath it sat instalments still calculated on a year the business had long outgrown.
What we did for An electronics assembler, Guelph, Ontario
We rebuilt the sales ledger by customer location, applied the correct place-of-supply rate to each stream, and filed the adjusted HST returns. Every new obligation — registration, remittance frequency, provincial filing — was set up before it was triggered, not after.
The result — An electronics assembler, Guelph, Ontario
$58,000 of cash was released from the working capital cycle, and the expansion completed with every registration and filing obligation covered from day one.

What we did for A B2B SaaS company, Guelph, Ontario
We cleaned up the historical file, registered the provincial payroll account, caught up the outstanding remittances, and applied for relief on the penalty, and prepared the due-diligence package the buyer's advisers actually asked for.

The deal closed at the agreed price. $625,000 of tax was saved against the structure originally proposed, with no post-closing adjustment.

Case Study 5 · Cash and remittance control
$155,000 Of Working Capital Freed From The Tax Cycle — Fintech Startup, Guelph
The situation — A fintech startup, Guelph, Ontario
A fintech startup in Guelph, Ontario was profitable on paper and short of cash every month. 13% HST charged on every sale regardless of where the customer was located explained most of the gap.
What we did for A fintech startup, Guelph, Ontario
We recalculated the corporate tax at the 12.2% combined small business rate and rebased the instalments on the current year and built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A fintech startup, Guelph, Ontario
$155,000 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
