What accounting and bookkeeping services do you provide in Canada?

We can provide complete financial services to Canadian businesses, including bookkeeping, payroll, GST/HST reconciliation, accounts receivable and payable, compilation engagements, investment accounting, and preparation of corporate and personal tax returns. Every engagement is tailored to your industry, province, and CRA requirements so that you receive what you need.

How do you meet the CRA regulations and Canadian tax laws?

Our CPA-designated professionals are abreast of all CRA bulletins, legislative developments, and provincial tax changes. We have a proactive compliance calendar of all clients, the dates of T2 returns, T4 slips, HST/GST remittances, and annual corporate filings. A deadline will never be a surprise; we submit before the deadline and maintain our records audit-ready at all times

Do you deal with businesses in all provinces and territories of Canada?

Yes, we have customers in Ontario, British Columbia, Alberta, Quebec and all other provinces and territories. Our team is fully conversant with provincial tax, WSIB, and WCB obligations, as well as provincial-specific filing requirements. In companies with operations in more than one province, we handle your compliance as a single, integrated interaction.

Which accounting software will you use, and can it work with my current systems?

Our major partners in cloud accounting are QuickBooks Online, Xero, Sage 50, FreshBooks, and Dext, and our payroll partners are Wagepoint and Ceridian Dayforce. When you are already on one of these systems, we fit right into your already existing workflow. Otherwise, we will advise you, establish you on, and transfer you to the appropriate platform that suits your business.

How much does your service cost?

We use the scale of the business, its complexity and the volume of transactions, and charge transparent fixed monthly fees no unexpected end-of-year invoices. We can only provide the correct figure by booking a free 15-minute discovery call, during which we evaluate your needs and offer a concise, obligation-free proposal. Our fees are offset by the tax savings and efficiencies that we find for most clients.

Can you assist me when books are overdue or if I have not submitted returns?

Yes, being up-to-date on overdue books and unfiled returns is among the most frequent cases that we service. We will examine your records, recreate lost data, and perk up all outstanding limited filings, including voluntary disclosure applications to the CRA, where necessary. When we are caught up, we put systems in place to prevent such situations in the future.

How do I get started with Aone Outsourcing Solutions in Canada?

ust reserve your free 15-minute discovery call – it is free; no documents are needed. We negotiate on your behalf, analyse your needs, and draft a proposal that suits you. After being engaged, you will be onboarded into our secure client portal and then assigned a professional as your main point of contact. The majority of clients are implemented in five to seven business days.
