Full Finance Office — Mississauga & GTA
Full Finance Office for Mississauga SMBs — Your Whole Accounting + Finance + Tax Function, One Mississauga Partner
We don’t just do your taxes. We don’t just keep your books. We become your finance department — replacing your in-house controller, bookkeeper, tax accountant, and advisor with a single AI-first CPA firm based in the Greater Toronto Area.
Mississauga + Toronto + Brampton + Oakville coverage
Bookkeeper + controller + tax CPA + CFO advisor, one firm
Assurance capability for reviews and audits when needed
One monthly invoice, no billing-by-the-hour surprises
The “Full Finance Office” Concept
What does it mean to outsource your entire finance function?
A full finance office is not a bookkeeper. It is not a tax preparer. It is the complete finance and accounting infrastructure that a 10–50 employee business needs to operate at a professional level — financial reporting, corporate and personal tax, payroll oversight, assurance, strategic advisory, and CRA representation — all delivered by a single engaged CPA principal.
When you engage Insight Accounting CPA as your Full Finance Office, you are not outsourcing tasks. You are replacing a function. We become your finance department. Every number that leaves your business goes through a CPA. Every tax decision is planned, not reacted to. Every financial statement is signed by a Licensed Public Accountant.
Who It’s For
10–50 Employee Mississauga Business
You have revenue and complexity, but you haven’t justified a full-time CFO or controller. You’re at the inflection point where a part-time bookkeeper and year-end CPA isn’t enough.
Owner-Manager Who Wants Out of Finance
You should be running your business, not reconciling accounts. You want to hand over the entire finance function and trust it’s covered.
Growing Construction or Trades Company
Job costing, holdback management, subcontractor T4As, and CIS compliance require a CPA who understands construction. We do.
Professional Services Firm
Dental, medical, legal, engineering: professional corporation tax planning, spouse salary strategies, and personal holding company structures require specialist knowledge.
NPO or Registered Charity
Charitable registration compliance, T3010 filing, restricted fund accounting, and audit/review requirements for government funding — all in one place.
Multi-Entity Group
Holding company + operating company + real estate entity? We manage intercompany flows, consolidated reporting, and group tax planning as a single engagement.
What We Replace
Monthly financial reporting, budget vs. actual variance, year-end close — all handled without a $90K salary.
Full-cycle bookkeeping in QBO or Xero, supervised and reviewed by a CPA principal.
T2 corporate, T1 personal, HST filings, T4/T5 slips — all under one roof, year-round.
Strategic financial advisory integrated into your monthly engagement, not billed separately by the hour.
What We Add
Anomaly detection, variance flagging, and report drafting accelerated by AI tools — reviewed by Bader.
As a Licensed Public Accountant, Bader can sign review engagements and audits — required by many lenders and government grants.
Not year-end reactive filing. Quarterly tax planning reviews are built into every Full Finance Office engagement.
Letters, audits, objections — Bader handles CRA directly, so you don’t have to.

- Discovery Call (30 min): We review your current setup, pain points, and goals. We give you an honest assessment of what you need and what you don’t.
- Scoping & Proposal: We send a fixed-fee proposal with a clear scope of work, deliverables, and timeline. No vague retainers.
- Onboarding (1–2 weeks): Secure QBO/Xero access, review of prior-year returns and financials, intake meeting with key team members.

Pricing Approach
Fixed Monthly Fee — Scoped After Discovery
Estimated range: $4,000 – $12,000/month + HST
Full Finance Office engagements are priced as a single fixed monthly fee covering all included services. Factors that affect pricing include number of entities, transaction volume, employee count, payroll complexity, and advisory hours. Assurance engagements (review or audit) are scoped separately.
Frequently Asked Questions
What does “full finance office” actually mean?
It means we replace every finance function your business needs: bookkeeping, monthly financial reporting, T2 corporate tax, T1 personal tax, HST filings, payroll oversight, CRA representation, strategic advisory, and assurance when required. One engaged CPA principal touches every deliverable. You stop managing multiple vendors and start having a single point of accountability for your entire financial function.
Can you handle a review or audit engagement for a Mississauga business?
Yes. Bader A. Chowdry is a Licensed Public Accountant (LPA) under CPA Ontario, which authorizes him to sign review engagements and perform audits of companies that do not require a PCAOB-registered auditor. Many lenders, government programs, and charitable funders require reviewed or audited financial statements. This capability is available as part of a Full Finance Office engagement or as a standalone assurance engagement.
Is this service available for multi-entity groups in Mississauga?
Yes. Multi-entity groups — typically a holding company, one or more operating companies, and sometimes a real estate entity — are a core use case for Full Finance Office. We handle consolidated reporting, intercompany transactions, group tax planning, and the T2 filings for each entity under a single engagement.
Do you work in-person with Mississauga clients?
Most of our work is done remotely via video call and secure file-sharing platforms. For Mississauga and GTA-area clients, we are available for in-person meetings at your office or a mutually convenient location on request. Year-end and onboarding meetings are the most common in-person touchpoints.
How is this different from just hiring a CPA firm for year-end?
A year-end CPA engagement is reactive: they receive your books in April and file your T2 in June. A Full Finance Office engagement is proactive and year-round: monthly reporting keeps your books current, quarterly tax planning prevents surprises, and strategic advisory runs in parallel with your business decisions. You get a finance department, not a once-a-year invoice.
Can I start with a smaller engagement and scale up?
Absolutely. Some clients start with monthly bookkeeping + T2 filing and progressively add payroll oversight, monthly reporting, advisory, and assurance as their business grows. Your engagement scope is reviewed annually and can be amended with reasonable notice. You are never paying for services you don’t need yet.
