      So sphiscated accounting systems I must say. For what? Never saw an irs payable in any return they asked me to prepare although I’m no licensed accountant. No names no whistle just a honest google review. Makes me wonder what an accountant does, cooking books or AICPA reporting them. No mark up in my basis. The roc building is beyond comprehension though, they even do SNL up or down stairs never got to see a show so I don’t know

      Deloitte completely failed implementation of Army IgnitEd, which led to thousands of service members paying out of pocket for education expenses. The circus that we watched unfold leaves me with zero confidence in the services that this firm provides.

Frequently Asked Questions

What do Montreal accounting firms do?

Montreal accounting firms help businesses and individuals stay financially organized and navigate Quebec and Canadian tax laws. They handle day-to-day money matters and offer guidance to support better financial decisions. Core services include: 

What information do I need to provide to an accounting firm?

At the beginning of your collaboration with an accounting firm, you will need to provide basic identification documents (legal name, tax ID, and contact details), your previous year's tax filing, and all pertinent financial records.  

These financial records must cover all sources of income, including forms like W-2s, 1099s, and investment documentation, as well as proof of all deductible expenditures, i.e., receipts, invoices, and bank statements. 

How do Montreal accounting companies calculate their rates?

Montreal accounting companies typically use three core structures when calculating their rates: hourly billing, fixed project fees, and annual retainer packages. The final cost is determined by the scope and complexity of the services, specifically whether the work involves just bookkeeping and basic tax filing or advisory services as well (auditing, tax planning), as well as the firm’s specialization and location.  

How can I verify an accounting company's credentials?

You can verify an accounting company's credentials by checking the public register of the Ordre des comptables professionnels agréés du Québec (CPA Order) to confirm that the individual CPAs are members in good standing and authorized to practice public accounting. Additionally, it is recommended to search the Order's records for any disciplinary decisions or limitations on their practice rights. 

Can Montreal accounting firms scale services as my business grows?

Montreal accounting firms are typically well-equipped to scale their services as your business grows, transitioning from basic compliance and bookkeeping for smaller operations to more complex assurance, tax planning, and fractional CFO advisory roles as your needs evolve.  

The majority of the firms offer modular packages that allow businesses to add services like audit preparation, business valuation, and specialized international tax advice as their needs expand.
