Due-Diligence Accounting Support Frequently Asked Questions

Direct answers to what Canadian business owners actually ask before hiring an accountant.

How much does Due-Diligence Accounting Support cost in Canada?

Due-Diligence Accounting Support starts at a fixed fee quoted before any work begins. The quote is locked at the outset and does not change mid-engagement, and you pay only after you have reviewed and approved the deliverable. Compare every plan on our transparent pricing page.

What documents do I need for Due-Diligence Accounting Support?

At minimum: prior-year returns and notices of assessment, your bank and credit-card statements for the fiscal period, payroll records if you have employees, and GST/HST filings. We send a checklist tailored to your situation after the free 15-minute call.

How long does Due-Diligence Accounting Support take?

Most engagements are completed within 3 to 5 business days once your documents are complete. Catch-up work covering multiple years takes longer, and we tell you the realistic timeline before you commit rather than after.

What happens if the CRA reviews or audits my filing?

We respond on your behalf at no extra charge for any return we prepared. Every figure we file is supported by documentation retained in your file, which is what turns a CRA review from a crisis into correspondence. See how our CRA audit support works.

Can you handle late or missed filings?

Yes. Late filing penalties compound at 5% of the balance owing plus 1% per month, so the cost of waiting is real. We prioritise catch-up work and, where eligible, file under the CRA's Voluntary Disclosures Program to reduce penalties.

Do you work with businesses outside major cities?

Yes. We are a cloud-based practice serving every province and territory, so your location does not change the price or the service. Browse our coverage across Canada to find your city.

Which industries do you specialise in for Due-Diligence Accounting Support?

We work across construction, healthcare, e-commerce, professional services, restaurants, real estate, transportation, technology and non-profits, each with its own deduction profile and CRA scrutiny patterns. See all industries we serve.

What makes Due-Diligence Accounting Support different from filing it myself?

Software applies the rules you already know about. A CPA finds the ones you do not: capital cost allowance timing, the small business deduction threshold, shareholder loan repayment rules, and TOSI exposure on family dividends. The fee is usually smaller than the deductions it surfaces.

What is included in Due-Diligence Accounting Support services?

Our due-diligence accounting support services include complete filing, compliance management, and strategic advice customized to Canadian tax laws.

How do I start with Due-Diligence Accounting Support services?

You can start by booking a free 15-minute call. We will review your files, provide a fixed quote, and start working immediately.
