They Switched to Aone—and Never Looked Back
We’re a growing e-commerce business, and reconciling daily sales from multiple platforms was becoming a nightmare. Aone set up automated systems and now everything syncs like magic. Our books are finally accurate and up to date.

Arnaud T.
E-commerce Store Owner, TorontoOur year-end books were always a scramble. As a nonprofit, we needed clean, audit-ready books, but we didn’t have the in-house staff. Aone Outsourcing Solutions stepped in with expert year-end support. Now, audits are smooth, and we have peace of mind.

Aisha R.
Nonprofit Director, CalgaryWe were paying a local accountant too much for too little. The service was slow and expensive, and we always felt in the dark. With Aone, we pay less and get more. Reports are clear, service is fast, and we finally feel in control.

Jason T.
Construction Firm Owner, MontrealPayroll errors were costing us time and trust with employees. We struggled with T4s, missed deductions, and keeping up with CRA changes. But thank God Aone’s payroll team came in and cleaned everything up. Now our staff gets paid accurately and on time, every time.

The overall cost of outsourcing accounting is determined by the transactions and services that might be due. The cost of accounting and bookkeeping can start from hundreds of dollars and can go to thousands of dollars in Canada.
Outsourcing your bookkeeping services means getting a professional accounting firm to help your company compile your finances. All these correspond to such tasks as invoicing, payroll, accounts payable, and bank reconciliation. Contracting out of such processes relieves your time and means you can focus on other business operations.
Outsourcing is beneficial because it removes time from your hands, saves cost and increases efficiency by allowing you to hand over tasks involving tax preparation, payroll handling, and bookkeeping to experts. It also means that you would not violate any Canadian regulations and, therefore, you can have more time to focus on business growth.
Our team also holds profound knowledge and experience working with the Canada Revenue Agency (CRA) regulations. Your business goes through checking that it meets all the regulatory requirements.
Yes! We provide outsourcing services to various industries, including healthcare, e-commerce, real estate, law firms, manufacturing, and professional services. Our accounting solutions are customised to meet industry-specific compliance and financial needs.
Absolutely! We ensure accurate bookkeeping and timely tax filings, reducing last-minute stress. Our tax professionals help optimise tax savings with GST/HST filings, corporate tax returns, and deductions.
Our team stays updated with CRA guidelines and Canadian tax laws. We ensure compliance with financial reporting standards, tax regulations, and industry-specific requirements to keep your business audit-ready.
Yes! We use cloud-based accounting software like QuickBooks, Xero, and Sage, allowing you to access real-time financial data from anywhere while ensuring data security and accuracy.
By outsourcing, you get accurate financial reports, timely invoicing, and efficient accounts payable/receivable tracking. This helps maintain healthy cash flow, reduce late payments, and improve overall financial planning.
Hiring an in-house accountant can be costly due to salaries, benefits, and training expenses. Outsourcing provides access to a team of experienced professionals at a lower cost, ensuring expertise in Canadian tax laws, compliance, and financial management—without the overhead of hiring full-time staff.
